1. PV and Controller Installation

Please follow manufacturer instructions for PV installation. Every PV installation must be equipped with a PV disconnect switch. Suitable switches are available from LORENTZ.

Install the controller close to the PV array in a shaded location to minimize cable length on the input side.

2. Electrical Installation

1. Pump wiring: The ECDrive must be connected to the

terminals L1, L2, L3 and to the earth connector the pcb. Observe rotation direction.

2. Accessories wiring: Connect a source low protector to terminals 1 and 2 (required). Remote control switches must be connected to terminals 3 and 4, water meters to terminals 5 and 6, 4– 20mA sensors to terminals 7 and 8 or 9 and 10, water sensors to 13, 14 and 15 and the SunSensor module to terminals 16 and 17. Terminals 11 and 12 are an output relay switch.

3. DC input wiring: Connect the positive terminal of the PV array to +, the negative terminal to −. Observe max. input voltage. If the controller is connected to a battery then battery mode must be activated in PumpScanner.

4. Grounding: A protective earth connection must be wired to the earth connector below the pcb.

2 Receipt, Storage and Handling

Check upon receipt that the packaging is undamaged and complete. If any abnormity is found, contact your supplier.

LORENTZ pumps are supplied from the factory in proper packing in which they should remain until they are to be installed at the site. Handle the pump with care and avoid unnecessary impacts and shocks.

Prolonged intermediate storage in an environment of high humidity and ﬂuctuating temperatures must be avoided. Moisture condensation may damage metal parts. Non-compliance can void the warranty. It is recommended storing the parts in a closed and dry room.

The motor, the pump end and controller can be stored (not used) in the range of –20 °C to +65 °C (–4 °F to +149 °F). The components should not be exposed to direct sunlight.

3 Product Speciﬁcation

3.1 General

LORENTZ solar submersible and surface pump systems are designed to efﬁciently deliver high volumes of water running exclusively on solar power. They are typically used in irrigation projects and for wide area drinking water applications where they reliably meet the most demanding requirements, economically, without pollution and without a grid connection or diesel generator.

A typical solar pumping system is composed of a PV generator array, a pump and a solar pump controller. Based on the design philosophy that it is more efﬁcient to store water rather than electricity, there is no energy storing device such as a storage battery in a typical solar pumping system.

The PV generator, an aggregation of PV modules connected in series and in parallel, absorbs solar irradiation and converts it into electrical energy, providing power for the whole system. The pump controller controls and adjusts the system operation and adjusts the output frequency in real-time according to the variation of sunlight intensity to realize the maximum power point tracking (MPPT).

Each LORENTZ pump system consists of a pump end, pump motor and a controller. This modular concept keeps all electronics above ground even for submersible pumps, simplifying servicing and lowering cost of ownership.

3.2 Features

LORENTZ pumps have the following features:

 Engineered in Germany using high quality non

corrodible materials  IP65/ NEMA 3A corrosion resistant controller housing  Pump control based on power available  ECDRIVE DC Brushless motors, speciﬁcally designed for

solar operation with up to 92% efﬁciency  Monitoring and management including on-board record-

ing of up to 5 years of performance data, smart device

access via PumpScanner Android™ App and integration

to LORENTZ pumpMANAGER remote management

service optionally available.

3.3 Approvals / Certiﬁcation

LORENTZ PS2 systems are sold in more than 130 countries. Versions and approvals requirements will vary from country to country. Please see the actual controller labelling to conﬁrm exact version and approvals marking. Full approvals certiﬁcates can be found on partnerNET.

4 Operating Conditions

Ambient requirements: PS2 pump systems can be oper-

ated up to 3000 meters above sea level and at an ambient temperature of up to 50 °C. When the temperature reaches the limit the power will be reduced automatically. The PS2 controller is designed for use in environments classiﬁed as pollution degree 3 in accordance with IEC-664-1: Conductive pollution occurs, or dry non-conductive pollution, which becomes conductive due to condensation, is to be expected.

Fluid: LORENTZ PS2 Helical Rotor (HR) and Centrifugal pumps can be used for drinking water supply, livestock watering and irrigation applications not containing solid or long ﬁbred particles larger than sand grains, with a max. grain size of 2 mm. The max. permitted sand content is 50 ppm, a higher sand content will reduce the pump life considerably due to wear. The max. salt content is 300-500 ppm at max. 30°C / 85°F. Defects due to pumping other liquids are not covered by the warranty.

LORENTZ PS2 Pool pumps can be used in chloride water, salt water and sea water swimming pools. When used in salt and sea water pools, the pump must be inspected and cleaned regularly.

LORENTZ PS2 BOOST pumps can be used for clean water applications only. The water must not contain any abrasive particles. It is highly recommended to install an intake strainer to protect the pump from any dirt ingress. Please refer to “8.6.4 Filtering” on page 54 for further information.

Fluid temperature: Depending on the type of your LORENTZ pump system, different requirements for ﬂuid temperatures apply:

PS2 centrifugal submersible - The maximum ﬂuid temperature for centrifugal submersible pumps is +50°C

(122 °F).

PS2 centrifugal surface - The maximum ﬂuid temperature for centrifugal surface pumps is +70°C (158 °F).

PS2 pool pumps - The maximum ﬂuid temperature for pool pumps is +60°C (140 °F).

PS2 helical rotor (HR) submersible - Designing and

building helical rotor pumps for a narrow range of ﬂuid temperature is important to ensure the best possible efﬁciency. LORENTZ PS2 helical rotor pumps are available in ﬁve different temperature classes:

Temp. class 0: 0 – +10 °C (32 – 50 °F) Temp. class 1: +10 – +20 °C (50 – 68 °F) Temp. class 2: +20 – +30 °C (68 – 86 °F) Temp. class 3: +30 – +40 °C (86 – 104 °F) Temp. class 4: +40 – +50 °C (104 – 122 °F)

The pumps have a tolerance range of ±2 °C (±3.6 °F) regarding the respective temperature ranges, except for the lowest allowed temperature of 0 °C.

The temperature class is part of the pump units’ name tag, please refer to chapter”3.4 Naming” on page 8. The pump system shall only be operated within the temperature range speciﬁed upon ordering.

CAUTION – PS2-200 HR pump ends and pump units must always be ordered with the next higher temperature class, to avoid starting problems in weak irradiation conditions.

CAUTION – Operating the pump outside of the speciﬁed temperature range can lead to reduced efﬁciency and/or damage the pump and can void the warranty.

INFORMATION – Due to the precise tolerances within LORENTZ HR pumps there may be situations where a higher temperature class pump than the actual water temperature is recommended. These recommendations are based on prior experience of local water impurities and particulates within the water.

PS2 boost surface - The maximum ﬂuid temperature for boost pumps is +80°C (176 °F).

12 Pump System Sizing & Layout Diagrams

6 Pump System Sizing & Layout Diagrams

6.1 Pump System Sizing

To professionally size and install a water pumping system, depending on the pump type and application various variables need to be taken into consideration:

Static head - Vertical height from the dynamic water level to the highest point of water delivery.

Suction head - Vertical height from the water level to the pump inlet where the water level is below the pump inlet.

Pressure losses - Loss of water pressure due to pipe length and friction caused by pipe material and additional pipe line elements like elbows, valves.

For solar water pumping additionally local irradiation levels are necessary to calculate the available power during each day and the effect on water output.

To easily manage and consider the different variables, LORENTZ strongly advises to size pump systems with LORENTZ COMPASS, the solar pump planning software.

COMPASS is the LORENTZ tool for designing, planning and specifying solar pump systems. It

is available for download to all LORENTZ partners on partnerNET.

COMPASS is a PC-based tool to simply specify solar pumping systems in real time. It is based on NASA weather data and uses precise algorithms for even the most complex calculations.

By selecting the location from a list of more than 250,000 cities, entering the total dynamic head (TDH) and the necessary amount of water per day the software will automatically show suitable pump systems and the necessary size of the PV generator.

For more complex situations COMPASS offers features from suction head calculation to pipe type speciﬁc pressure loss calculation.

NOTE - Always ensure the values used for sizing with COMPASS match the conditions on site. Incorrect parameters can lead to a wrong sizing report.

7.1 General

WARNING – All electrical connections must be performed by qualiﬁed experts only.

WARNING – Do not dismantle the controller while still connected to the power supply! Before any installation, maintenance or inspection activities wait at least two minutes after the power supply has been disconnected from the controller!

CAUTION – To avoid multiple starts of the pump in twilight conditions, the Sun Sensor module must be connected and conﬁgured for all PS2-1800 CS-F and all PS2-4000 pump systems. Operating without a Sun Sensor module can lead to increased wear or damage to the pump. Such damage is excluded from the warranty.

CAUTION – Never let the pump run dry. Dry running will damage the pump and void the warranty. LORENTZ requires a dry run protection for every pump system.

For more information on mandatory accessories and their installation, please refer to “7.6.3 Pump Accessories Wiring” on page 27 and “9 Pump Accessories Installation” on page 57.

Treat the controller as industrial waste when processing the discarded controller. It is possible that some components could produce toxic and harmful gas.

A plug kit is available separately from the controller if plug connectors shall be used.

Figure 2: PS2 controller

DC Disconnect Switch

Electrical Conduit

Every solar pump system must be equipped with a properly sized DC disconnect switch. The switch must be installed between the PV generator and controller. It must meet the following requirements:

 minimum rating according to “Table 1: Minimum DC

disconnect rating” on page 17

 continuous current rating according to maximum

current of the connected PV generator or higher

 the switch must be rated for DC current, not AC

A PV disconnect switch matching all requirements above can be purchased from LORENTZ.

CAUTION – The use of a properly sized

disconnect switch is an important safety measure and obligatory for a professional installation of a solar pump system.

Table 1: Minimum DC disconnect rating

Controller Min. DC disconnect switch rating

PS2-150 50V DC

PS2-200 100V DC

PS2-600 150V DC

Electrical conduit is recommended. We recommend the use of an electrical conduit (pipe) to protect outdoor wiring from the weather, from human activities and from damage caused by animals. If you do not use a conduit, use a strong, high-quality outdoor cable. Where cables enter the junction box, install sealed strain-relief cable glands.

Wire sizes

For signal cables, the min. wire size should be 1.5 mm² (16AWG). For power cables, the min. wire size should be 2.5 mm² (14AWG). Compare your wire sizes to the LORENTZ COMPASS sizing reports. Cables should be shielded to meet EMC the requirement.

For outdoor use, cables meeting the requirements of 60245 IEC 66 are recommended. For indoor use, the recommended cable type is deﬁned in 60245 IEC 57. The installer must always consider the local situation, codes of practice and regulations and use a cable that meets these requirements.

7.4 Controller Placement

7.5 Mounting, Space and Ventilation Requirements

The controller must be protected from water, moisture and animals, so keep the controller box sealed. Place the controller in a dry and sufﬁciently ventilated environment.

Place the controller close to the solar array, not the pump, to reduce the risk of lightning damage. The controllers’ input circuitry is more sensitive to surges than its output. Therefore it is safest to minimize the length of the input wiring.

Electronic devices are most reliable when they are protected from heat. Mount the controller where it is shaded from the midday sun. An ideal location is directly under the PV generator. If no shade is available, cut a piece of sheet metal and bolt it behind the top of the controller. Bend it over the controller to provide shade. This is especially important in extremely hot locations. Extreme heat may trigger a thermal function in the controller causing it to reduce the power consumption or turn it off. The controller housing can reach high temperatures when operating at high ambient temperatures. This is normal and will not reduce the expected lifetime of the controller or its components.

PS2 controllers can be mounted side by side.

For grounding of the front cover the cover screws must be tightend to a minimum torque of 2Nm.

All PS2 controllers have a fan-less design; they are cooled by air convection. It is strictly advised not to install the controller in an additional enclosure. If an additional enclosure is necessary a sufﬁcient vertical airﬂow (from bottom to top) has to be ensured to allow sufﬁcient cooling.

PS2 controllers have a keyhole mounting system to simplify mounting on appropriate surfaces. For mounting on poles and similar structures the PS2 is compatible with the LORENTZ PM accessory brackets for a maximum of convenience.

When mounting the PS2 controller with the LORENTZ PM accessory brackets tighten the screws diagonally and evenly.

CAUTION – do not over tighten the mounting screws on the PS2 housing when using the PM accessory brackets to avoid damage to the PS2 controller housing.

CAUTION – When using PM accessory brackets, for high performance systems and/or with high ambient temperatures a backplate must be installed between the controller and the PM accessory brackets to preserve the funnel effect of the cooling ﬁns. Operating without a backplate can lead to insufﬁcient cooling which will result in reduced performance.

For controller dimensions, cf. “Table 3: PS2 Controller dimensions for installation” on page 20.

7.6 Wiring the Controller

WARNING – All electrical connections must be performed by qualiﬁed experts only! Unqualiﬁed handling might lead to shock, burns, or death.

WARNING – Beware of high voltage. Never work on a system connected to power or within two minutes after disconnection to avoid electric shock hazard.

Before starting to work on the electrical system make sure that all components are disconnected from the power source. Do not work on any components when power is connected or within two minutes after disconnection. The controller needs time to discharge.

Switch the system on only when all work is completed.

CAUTION – The controller should only be connected to power after correct wiring or the controller might get damaged.

CAUTION – Do not install disconnect switches in the power wires between the motor and pump controller. Connecting the motor wires to a switched-on controller may cause irreparable damage. Such damage is excluded from the warranty.

CAUTION – Solar-direct systems only – Do not connect any electrical load to the PV generator other than the LORENTZ pump controller. Connection of a battery charger, active solar tracker controller, electric fence charger, or other load simultaneously with LORENTZ PS2 systems may interfere with the controller and prevent proper operation.

CAUTION – Measure the voltage before connecting power to the controller. Voltage (open circuit) must not exceed the max. DC input (refer to “Table 2: Technical data of the PS2 controller” on page 18).

7.6.2 Pump Wiring

The motor cables of the pump have a marking to allow correct wiring. Connect the wires using this sequence:

 1: Motor cable L1  2: Motor cable L2  3: Motor cable L3

 : Ground connection

If necessary, interchange any two phases to reverse direction. Refer to chapter “8 Pump Installation” on page 32 for detailed pump installation instructions.

7.6.3 Pump Accessories Wiring

Terminals 1 and 2

To protect the pump from being damaged by dry running connect a suitable source low protection switch to terminal 1 and 2. Every pump system must be equipped with dry run protection. If dry run protection is not needed, add a jumper wire between these two terminals.

CAUTION - Never let the pump run dry. Dry running will damage the pump and void the warranty. LORENTZ requires a dry run protection for every pump system.

Terminals 3 and 4

Connect any kind of external switch for remote control of the controller. To run the pump the switch must be closed (NC). If no switch is used the terminals No. 3 and 4 have to be connected with a jumper cable (factory setting).

Terminals 5 and 6

Install a water meter in the pipeline and connect it to terminal 5 and 6. The output of the water meter must be an impulse signal. The time between two impulses must not exceed 5 minutes. The DataModule can handle up to 10 impulse per second. Select a water meter appropriate for the expected ﬂow. The ﬂow can be viewed with the LORENTZ PumpScanner software.

Terminals 7 and 8 / 9 and 10 Any suitable sensor for 24VDC supply voltage, current (signal) range of 4–20mA and load impedance of 100Ω can be connected, e.g. LORENTZ pressure sensor, LORENTZ liquid level sensor. The sensor must then be conﬁgured in PumpScanner.

Terminals 11 and 12 This is a potential-free signal output contact that can be conﬁgured in PumpScanner to control third party devices. It is rated for: 24VAC, 24VDC, 1A.

Terminals 13, 14 and 15 Connect a water sensor to detect the presence of water, this is usually installed on the suction side of surface pumps for dry run protection. If no water sensor is connected a jumper wire must be installed between terminals 14 and 15 (factory setting). The maximum allowed current for sensor supply is 20mA.

Terminals 16 and 17 Connect a LORENTZ 1.5Wp Sun Sensor module module. This PV module is used to measure the solar irradiation and allows you to set irradiation dependent START / STOP values for the pump. These settings can only be done via LORENTZ PumpScanner.

CAUTION – Only connect a suitable sensor to terminals 7 and 8 / 9 and 10 / 13, 14 and

15. Never create a short circuit. Observe the polarity of the pressure sensor.

CAUTION – An input voltage higher than speciﬁed in “Table 5: Max. voltage input” on page 28 will damage the controller and void the warranty. Damage may occur if the solar generator array is wired incorrectly. Measure the voltage and conﬁrm the polarity before connecting the power to the controller.

Connect the positive terminal of the PV modules to + and the negative terminal of the PV modules to –. Connect the protective ground wire to an appropriate ground system. Refer to “7.6.1 Terminal Descriptions” on page 22 for terminal descriptions and to “7.6.6 Grounding” on page 30 for grounding instructions.

7.6.5 Input Wiring for Battery-based Systems

CAUTION – The PS2-4000 pump system can not be operated from batteries.

The battery mode for PS2-150 to PS2-1800 controllers must be activated in PumpScanner. This will deactivate the MPP-Tracking function and activate the Low Voltage Disconnect (LVD).

Connect the PS2 controller directly to the battery and NOT to the load terminals of the charger as the terminals may not be rated for the starting load current of the pump. The PS2 controller has a low voltage disconnect function to protect the battery from being deeply discharged.

Some charge controllers monitor the capacity of the battery and regulate the charging accordingly. This method does not work when the PS2 controller is connected to the battery. In order to provide correct charging the charger should be set to voltage orientated regulation. This may require a jumper to be set in the charger. Check the manuals of the charger manufacturer.

Short circuit protection: Install a fuse or circuit breaker near the power source. Use a 30 A circuit breaker or a time delay (slow blow) fuse.

Low-voltage disconnect function: Lead-acid batteries can be permanently damaged by over-discharge when the voltage falls below a critical point. To prevent this, the PS2 battery system controller will turn off at low voltage for at least 20 minutes, and turn back on only after the battery has recovered signiﬁcantly.

Battery high run mode: If high run mode is activated in PumpScanner, the low voltage disconnect points for 12V batteries are changed to OFF at 12.3VDC, ON at 13VDC.

7.6.6 Grounding

Before starting to work on the electrical system make sure that all components are disconnected from the power source. Only switch on the system when you have ﬁnished all work.

Grounding is mandatory to protect the users from potentially fatal electric shocks. It also protects against electric charging or a short circuit inside the device. This is accomplished through clamping, bolting or other mechanical means to provide an effective grounding path to the earth to ensure safe operation at all time.

The grounding is also important to the system for lightning protection. In general it is meant for indirect lightning strikes and induced electrical potentials during operation of the pump system.

Before installation, contact the local code authorities to determine the necessary grounding requirements.

Insufﬁcient ground source: Where there is an inadequate ground source you can use a grounding rod. A grounding proﬁle rod should be located not more than 4 – 5m (13 – 16 ft) from the controller. The cable must not carry any mechanical loads. The rod must be completely buried in the ground (2.5 m/8 ft below ground level). You must refer to local standards and requirements. The grounding cable should be a copper cable with a cross section of not less than 16 mm2 (AWG 6).

A protective earth connection must be linked to the controllers earth connector which is located below the pcb and marked with the protective earthing symbol . The protective earth wire of the motor must also be connected to the controllers earth connector.

The protective earth connection can also be linked to the grounding bolt on the outside of the controller near the cable glands.

All metallic support structures and electrical enclosures must be grounded.

For grounding of the front cover the cover screws must be tightend to a minimum torque of 2Nm.

For grounding of the PV generator, follow manufacturer instructions.

LORENTZ pump systems are extremely efﬁcient. It is important to keep this efﬁciency throughout the entire system. A main reason for loss of efﬁciency is pipe pressure losses. Make sure that you have included the pipe pressure losses during the sizing process of your system.

Consider a smart pipeline design from the beginning.

CAUTION – Consult COMPASS or a pipe pressure sizing chart to determine the correct size. Oversize the pipe line to reduce the pressure drop.

CAUTION – The length of the inlet and of the outlet pipeline must be considered for the calculation of the pressure losses

CAUTION – Only run the pump when it is completely preﬁlled with water (surface pumps), submersible pumps must be completely submerged. This means there must be no air in the pipes.

CAUTION – For surface pumps, air locks must be avoided at the inlet pipe line. Avoid sharp 90° elbows and sharp pipe size adaptors.

8.2 Pump System Type

8.1.2 Cable Splicing

To connect the motor cable with a cable extension you should connect the cable ends with a splicing kit.

It is very important that the cable joints are fully sealed otherwise moisture could cause a short circuit. This will damage the pump system.

For more information about connecting cable ends with a splicing kit see the “submersible cable splicing” manual in the package of the splicing kit.

CAUTION – Cable splice failures are a common source of errors. Check the splice for proper connections.

CAUTION – Bad cable splicing can damage the controller and/or the pump. Such damage is excluded from the warranty.

Depending on your pump system, please refer to the correct chapter for installation instructions:

To determine the type of system you have, please refer to chapter “3.4 Naming” on page 8.

34 Pump Installation

8.3 Submersible Pumps

For submersible pumps only: The ECDrives are water lubricated and therefore preﬁlled with water. If the motor is stored for more than three months, the water will have been pressed out; the rotor must be turned by hand before use to ensure that the rotor is not stuck.

8.3.1 Wiring the Pump

CAUTION - No disconnect switches must be installed between the motor and the pump controller. Connecting the motor wire to the switched-on controller might irreparably damage it. Such damage is excluded from the warranty.

CAUTION – If the pump wires are in the wrong order, the motor will run in reverse and the pump will not function correctly. Damage may result. Check the direction before installing the pump. The proper direction is counter-clockwise when viewed from above.

CAUTION – Never let the pump run dry. Dry running will damage the pump and void the warranty. LORENTZ requires dry run protection for every submersible pump system.

Figure 9: Exemplary LORENTZ submersible pumps

The motor cables of the pump have a marking to allow correct wiring. Connect the wires using this sequence:

 1: Motor cable L1  2: Motor cable L2  3: Motor cable L3

 : Ground connector

The submersible pump must be submerged in water before checking the correct rotational direction. The correct rotation direction for submersible pumps is counter-clockwise, viewed from the top. It is also labelled with an arrow on the pump end.

The testing process for rotational direction depends on the pump type. Please refer to the next page for detailed instructions on testing helical rotor (HR) and centrifugal submersible pumps. To determine which type of pump you have, please refer to “3.4 Naming” on page 8.

HR Pumps:

Centrifugal Pumps:

The HR pumps are positive displacement pumps and hence will only deliver ﬂow rate when running with correct rotation direction. They will be damaged when running in reverse.

A new pump “out-of-the-box” is shipped from the factory with a temporary lubrication ﬁlm on the rotor which allows a test run of max. 5 seconds in total without submerging the pump. Once the pump came in contact with water the temporary lubrication is gone and the pump must not be operated without being completely submerged! Submerging only the inlet is not sufﬁcient and will result in damage to the pump end.

Check the rotational direction as follows:

(1) Connect the pump to the controller and power supply.

(2) Observe the information regarding HR pump testing

above and follow them strictly!

(3) Start the pump and check the rotation direction by

observing the motor shaft at the pump inlet.

(4) Compare to the indicated rotation direction on the

pump end.

(5) In case the direction is wrong, switch off immediately

and change two of the three phase leads.

(6) Start the pump again and check the rotation direction.

Do not exceed 5 seconds of combined testing time.

Check the rotational direction as follows:

(1) Connect the pump to the controller and power supply.

(2) Start the pump and check the delivered ﬂow rate.

(3) Stop the pump, disconnect the power supply and

change two of the three phase leads.

(4) Start the pump again and check the delivered ﬂow.

(5) Stop the pump, disconnect the power supply and com-

pare the ﬂow rates from point 2 and 4. The wiring with the better ﬂow rate has the right rotational direction.

(7) The pump will only deliver water ﬂow when running

with correct rotation direction.

36 Pump Installation

8.3.2 Installation and Handling

To lower the pumps into the borehole, a crane or hoist is recommended, depending on the size and weight of your pump system.

All parts have to be strong enough to withstand the weight of the pump, the motor, the motor cable and the pipe system.

It is also helpful to lower a pump dummy into the borehole before you lower the pump to make sure that the hole is completely free and the pump can slide into the hole without obstructions.

WARNING – Never stand under suspended loads.

WARNING – Always take suitable security precautions (e.g. a strong safety rope) to safeguard the pump against slipping into the well during installation!

CAUTION – Be careful not to bend the pump, take particular care with centrifugal (C) pumps with a high number of stages. Make sure that the pump never stands on the motor cable, that the cable does not get jammed or damaged by sharp ledges or that the cable is not pulled or jerked where it enters the motor.

Round off the edges of a ﬂange to prevent damage to the cable. Do not ﬁx the cable tightly. Leave space for the pipes to expand. The cable needs to get ﬁxed every 3 m.

NOTE – Measuring and noting down the distances between the ﬁxing will help to lower the pump to the right depth.

Figure 10: Fixing of the motor cable at a joint and a strait pipe

tape

During the process of lowering the pump into the well the motor cable has to be ﬁxed properly to the pipe, see “Figure 10: Fixing of the motor cable at a joint and a strait pipe” on page 36. Where a plastic pipe is used, the longitudinal stretch of the pipe under load has to be considered by leaving a sufﬁcient gap between the pipe and the cable! The cable should be ﬁxed with water-resistant tape. It is a good installation practice to form a loop with the motor cable near the pump and repeat it about every 40 m / 130 ft along the riser pipe. This will keep any tensile forces away from the motor cable.

To extend the motor cable pay attention to chapter “8.1.2 Cable Splicing” on page 33.

8.3.3 Installation Depth

8.3.4 Removal

Make sure that the pump unit is suspended properly and is not in contact with sand and mud from the well bottom. It is recommended to install the pump above the ﬁlter zone (= water entry zone) of the well to keep the sand content in the water low and ensure proper cooling of the motor.

CAUTION – The pump must be submerged completely. Never let the pump run dry. Dry running will damage the pump and void the warranty. LORENTZ requires a dry run protection for every pump system.

CAUTION – If the pump does not hang above the ﬁlter zone a ﬂow sleeve is necessary.

If you have to remove the pump system it is the same principle as the installation in reverse order. When removing the pump the pipes will be full of water and will be heavier.

CAUTION – When the pump system is lifted out of the well the pipes are full of water. This causes additional weight.

In the table below you can see the additional weight of the water per meter pipe length.

8.3.5 Additional Features

8.3.5.1 Safety Rope

We recommend the use of a safety rope as a loss insurance. If the pipe breaks because of start-up torques of the motor, too much weight, pipe corrosion or wrong installation a safety rope can prevent the total loss of the pump system and damage to the well.

Choose a safety rope that can handle the weight of the whole installation and the water inside the pipes. The rope material must be water-resistant. Near the well head the rope needs to be UV-resistant or protected from sunlight.

CAUTION - Do not use a nylon rope. Nylon is known to absorb water over time which will weaken the rope.

8.3.5.2 Plastic Pipes

When the pipes are strong enough the use of plastic pipes is possible. If you are not sure about the strength of your pipes contact the pipe manufacturer.

CAUTION - The pipes must be strong enough to hold the whole weight of the pump, the motor, the pipe system and the water in the pipes. It must also withstand the water pressure generated by the total dynamic head.

8.3.5.3 Stilling Tube

For the maximum recommended sand content, before any signiﬁcant detrimental effects occur, check chapter “4 Operating Conditions” on page 9.

A higher content will cause excessive wear within the pump and reduce the pump’s life span considerably. Any pump that is blocked by sand will not be covered by warranty.

To reduce the amount of particles entering the pump, a stilling tube can be installed, see “Figure 11: Stilling tube”.

Figure 11: Stilling tube

CAUTION - When using plastic pipes you should always use a safety rope.

8.4 CS-F Surface Pumps

8.4.1 Placement and Foundation

Rain and weather protection – The pump is equipped

with IPX4-type motor protection. If it is installed outside, the pump must be protected from rain and direct sunlight. This will increase the durability of your pump.

CAUTION – CS-F pumps must not be submerged in water or subjected to rain or dripping water.

CAUTION – If the pump is installed in a humid area, effective ventilation and aeration must be provided in order to prevent condensation.

CAUTION – When installing in very small installation spaces the natural cooling may be insufﬁcient. Carefully consider the ventilation in order not to exceed the maximum ambient temperature.

CAUTION – The pump might heat up in operation. The pump must not be installed on combustible surfaces. Strong incombustible surfaces should be used, e.g. concrete or stone surfaces.

Foundation – An arrow on the pump base shows the

direction of the ﬂow of the ﬂuid through the pump. It is recommended to install the pump on a concrete foundation. The foundation must be level and should have min. approx.

1.5 times the weight of the pump to absorb vibration, shock and strain.

Connecting the pump to the foundation – Fastening the pump to the foundation should be done exclusively by means of properly sized bolts or threads (dowels) in order to avoid any movement of the pump unit.

CAUTION – The pump must be mounted vertically.

Space – During installation, make sure that there is enough

space available to permit subsequent disassembly of the motor unit. It is recommended to have at least 1m of free space above the pump.

Figure 12: Exemplary LORENTZ surface pumps

40 Pump Installation

8.4.2 Pump Motor Wiring

WARNING – The wiring has to be done by qualiﬁed service personnel only.

WARNING – Beware of high voltage! Electric shock hazard!

The ECDRIVE must be connected to the terminals L1, L2, L3 and the ground connector. The ECDRIVE requires four-conductor (four-wire) cable between the controller and the motor. The three wires L1, L2 and L3 carry power. The fourth wire carries ground. Connect the ground wire to the ground connection below the pcb in the controller. Grounding helps to prevent shock hazard if there is a fault in the motor.

The correct order of the three motor phases is marked on the motor cables itself. Prior to splicing the order of the motor phases should be transferred to the cable. This will simplify the wiring.

CAUTION – No disconnect switches must be installed in power wires between motor and pump controller. Connecting the motor wires to a switched-on controller may cause irreparable damage which is excluded from the warranty.

CAUTION – If the pump wires are in the wrong order, the motor will run in reverse and may damage the pump. Never let the pump run dry, not even for the purpose of checking the direction of rotation.

Check the correct rotation direction after the pump is ﬁlled with water, see chapter “8.4.5.2 Rotary Direction” on page

44.

8.4.3 Installation and Handling

Handling – When lifting the pump use the eyebolts at the

motor housing. If that is not possible lift the pump at the motor ﬂange by using a holder or straps.

Strainer – If pipelines are welded together metal pieces might be present in the pipeline. Before pump installation, the inlet pipeline must be carefully cleaned. It is recommended to install a strainer about 1 m / 3 ft in front of the pump inlet to avoid pump damage due to any kind of impurities (cp. “Figure 13: Strainer”). The pressure drop of the strainer must be considered in the suction lift calculation.

Pipe system – We advise that pipe expansion joints are used close to the pump on both inlet and outlet to reduce noise and vibration (cp. “Figure 14: Pipe expansion joints”). It is recommended that you install a gate valve in the suction and discharge pipeline close to the pump to avoid draining of the pipe while cleaning (e.g. ﬁlters), repairing, servicing or replacing the pump system.

WARNING – Inlet and outlet pipes must be mounted to the pump housing free of tension.

CAUTION – Make sure that the suction pipe is sealed with no leaks, otherwise the pump will not prime or will prime insufﬁciently.

CAUTION – The pumps are shipped with plastic covers on the pump inlet and outlet. Remove them before connecting the pipes to the pump.

Check valve – A check valve at the inlet pipe is needed

to assure that the pump and its suction pipeline remains completely water ﬁlled during the time the pump is switched OFF. Always install a check valve with one inch (1”) larger diameter than the suction pipe in order to avoid too much suction pressure drop. For example if the suction pipe size is 3”, then a 4” check valve should be installed.

42 Pump Installation

8.4.4 Suction Head

The maximum suction head is limited by the local air pressure, the water temperature of the medium, the pipe losses and the NPSH value of the pump.

CAUTION – If the suction pressure in the pump is lower than the vapor pressure of the ﬂuid, cavitation will occur. Cavitation creates noise and will damage the pump. Damage due to cavitation is not subject to warranty. To avoid cavitation, the pressure of the ﬂuid must be maintained above its vapor pressure at all points as it passes through the pump.

The maximum suction head (H) must be calculated in advance. The LORENTZ pump sizing software COMPASS can be used for NPSH calculation.

8.4.5 Initial Start-up

CAUTION – Never start the pump if it is not ﬁlled with water and has not been vented. The pump and suction pipe must be fully ﬁlled with clean water otherwise the pump will be damaged

8.4.5.1 Filling Pump with Water

The pump and the whole suction pipe must be fully ﬁlled with clean water.

If the water source level is higher than the pump inlet:

1. Close the gate valve in the outlet pipe and loosen the air vent screw.

2. Open the gate valve in the suction pipe slowly.

3. Tighten the air vent screw when water streams out continuously.

If the water source level is below the pump inlet:

Suction pipeline and pump must be ﬁlled with water manually.

1. Close the gate valve in the outlet pipe and open the gate valve in the suction pipeline.

2. Loosen the air vent screw and ﬁll clean water into the pump through the ﬁller pipe.

3. Fasten the air vent screw after the pump and the suction pipeline are completely ﬁlled with water.

WARNING – Do not start the pump until it has been ﬁlled completely with water.

WARNING – Make sure that the installed shutoff valves in the suction and pressure lines are completely open during operation, the pump must never run with shutoff valves closed!

Figure 15: Vent and drain holes

CAUTION – Installing a suitable ﬁller pipe is highly recommended for proper priming of the pump system. A pump system which is not primed completely will likely get damaged when it is switched on.

CAUTION – A nonreturn valve must be installed at the start of the inlet pipeline otherwise it is impossible to prime the pump successfully.

8.4.5.2 Rotary Direction

CAUTION – Never let the pump run dry, not even for the purpose of checking the direction of rotation! Dry running will damage the pump and void the warranty.

Switch on the power supply and look at the rotary direction by looking at the motor fan. An arrow on the pump unit indicates the correct direction of the rotation.

Viewed from the top, the pump turns counterclockwise.

8.4.5.3 Final Check-up

Check whether the foundation bolts are fastened, the pump and suction pipes are completely ﬁlled with water, the voltage of the power supply is correct and that the pump turns correctly. Make sure all pipelines are connected tightly and can supply water normally. Make sure there is no closed valve or other obstruction in the water line.

8.5 Pool Surface Pumps

8.5.1 Placement and Foundation

CAUTION – This pump is for use with permanently-installed pools. Do not use with storable/temporary pools.

CAUTION – The drain hole/pipe on the bottom between pump housing and motor must never be clogged or sealed. Blocking the drain hole will result in an internal build-up of water which will damage the motor! Ensure that any drainage cannot cause consequential damage! If necessary provide a suitable drip pan.

CAUTION – If the pump is installed in a humid area, effective ventilation and aeration must be provided, in order to prevent condensation.

CAUTION – The pump must be mounted in horizontal position.

WARNING – The pump might heat up in operation. The pump must not be installed on combustible surfaces. Strong incombustible surfaces should be used, e.g. cement or stone surfaces.

Rain and weather protection – The pump is equipped

with IPX4-type motor protection. If it is installed outside, the pump must be protected from rain and direct sunlight. This will increase the durability of your pump.

Foundation – Installing the pump on a concrete foundation is recommended. The foundation must be completely even and level. Its purpose is to absorb vibration and strain in addition to preventing stress on pipe ﬂanges.

Connecting the pump to the foundation – Fastening the pump to the foundation should be done exclusively by means of M8 bolts or threads (dowels) in order to avoid any movement of the pump unit.

8.5.2 Pipe Sizing

Operating noise – Make sure, by applying appropriate

measures, that the local environment will not be impaired by pump operating noise.

Table 7: Operating noise

Pump system Max. noise level

PS2-600 CS-17-1 65db

PS2-1800 CS-37-1 68db

Space – During installation, make sure that there is enough space available to permit subsequent disassembly of the motor unit in the direction of the motor fan (minimum 120 mm / 4.7”) and of the strainer basket above (minimum 140 mm / 5.5”).

When installing in very small spaces the natural cooling may be insufﬁcient and additional ventilation may be required. Carefully consider the ventilation in order not to exceed the maximum ambient temperature.

LORENTZ pump systems are extremely efﬁcient. It is important to keep this efﬁciency throughout the entire system. A main reason for loss of efﬁciency is pipe pressure losses. Make sure that you have allowed for pipe pressure losses during the sizing process of your system.

CAUTION – Consult COMPASS or a pipe pressure sizing chart to determine the correct pipe size. Oversize the pipe line to reduce the pressure drop.

CAUTION – The length of the inlet and of the outlet pipeline must be taken into consideration when calculating pressure losses.

CAUTION – Air locks must be avoided at the inlet pipeline. Avoid sharp 90° elbows and sharp pipe size adaptors.

Figure 17: Prevent air locks in pipes Figure 18: Avoid 90° elbows and size adaptors

8.5.3 Installation and Handling

CAUTION – The pump unit may be installed at either a maximum of 3 m / 9’10” below (gravity feed) or above (suction mode) the water level.

The suction lift may be signiﬁcantly reduced by ﬂow resistance in the suction line (if the pipes are very long and/or insufﬁciently dimensioned). The suction/inlet pipe should be as short as possible.

NOTE – Inlet and outlet of PS surface pumps for pools are metric sized. The pumps are supplied with adaptors which are compatible with local market requirements.

When ordering pumps for US/imperial (inch) markets adaptors are provided to connect standard NPS (inch) pipes.

When ordering pumps for metric markets adaptors are provided to allow connection of the next sized up metric pipe. The table below shows the outer pipeline dimensions for the pump inlet and outlet pipe using the supplied adaptors.

The nominal pipe size (NPS) and the outer dimensions (OD) values are not equal between 1/8 to 12” sizes. For example, the OD of an NPS 2” pipe is actually 2.375”. Please pay attention to the actual dimensions of the pool pipework.

Before joining the pipework to the connecting pieces of the housing, the adhesive surfaces must be cleaned completely. Pay attention to the gluing and safety instructions of the adhesive manufacturer.

Pipe system – We advise that pipe expansion joints are used on both sides near to the pump to reduce noise and vibration. It is recommended that you install a gate valve in the suction and discharge pipeline close to the pump to avoid draining of the pipe while cleaning (e.g. ﬁlters), repairing, servicing or replacing the pump system.

CAUTION – Inlet and outlet pipes must be mounted to the pump housing in a way that is free of tension.

CAUTION – Make sure that the suction pipe is sealed with no leaks, otherwise the pump will not prime or will prime insufﬁciently.

Check valve – If the pump is installed above water level a

check valve at the bottom of the inlet pipe is needed in order to ensure that the pump and its suction pipeline remain completely water ﬁlled during the time the pump is OFF. In order to minimize pressure losses, the check valve should be sized correctly. Always install a check valve which is one inch (1”) larger than the suction pipe in order to avoid too much suction pressure drop. For example, with a 3” suction pipe a 4” check valve should be installed.

Strainer – Never operate the pump without having the strainer basket in the pump housing. A full or dirty strainer will impair the ﬂow rate and the ﬁltration. The strainer basket must be regularly emptied and cleaned. Pay attention to chapter “12.2 Cleaning the strainer”.

48 Pump Installation

8.5.4 Initial start-up

CAUTION – Never start the pump if it is not ﬁlled with water

8.5.4.1 Filling Pump with Water

Where the water level is above the pump inlet:

(1) Close the gate valve of the inlet and outlet pipe.

(2) Loosen the lid above the strainer basket by turning

anticlockwise (i.e. you may use the opening device included in the delivery). Coat the O-ring seal with petroleum jelly, close the lid by hand and make sure that it ﬁts properly (thread is not jammed). Failure to do this will result in the pump not priming correctly.

(3) Open the gate valve in the inlet and outlet pipe slowly.

(4) Reopen the lid a little to remove the remaining air

below the lid. As soon as water starts to stream out of the lid, tighten it by hand.

Where the water level is below the pump inlet:

(1) Open the gate valve in the suction pipeline.

(2) Loosen the lid above the strainer basket by turning

anticlockwise (i.e. you may use the opening device included in the delivery). Slowly ﬁll the pump and the suction pipeline with water until the pump housing is completely ﬁlled with water. Coat the O-ring seal with petroleum jelly close the lid by hand and make sure that it ﬁts properly (i.e. that the thread is not jammed). Failure to do this will result in the pump not priming correctly.

CAUTION – A check valve must be installed at the beginning of the inlet pipeline.

CAUTION – Do not start the pump until it has been ﬁlled with water completely.

8.5.4.2 Rotary Directon

8.5.4.3 Final Check-up

CAUTION – Make sure the pump turns freely, especially after extended periods of down-time. To check this, put a screwdriver into the slot at the fan end and turn by hand in the direction of rotation. If necessary remove fan cover and turn the fan by hand.

CAUTION – Never let the pump run dry, not even for the purpose of checking the direction of rotation!

An arrow on the pump unit indicates the correct direction of rotation. Switch on the power supply and look at the rotary direction by looking at the motor fan. If the direction is wrong, swap over any two of the power wires at the controller.

Check that the foundation bolts are fastened, the strainer basket is installed, the pump is fully ﬁlled with water, the voltage of the power supply is correct and that the pump turns correctly. Make sure all pipelines are connected tightly and can supply water normally. Recheck the tight ﬁt of the lid, after the pump has run. Due to suction pressure it might be necessary to retighten it.

CAUTION – Make sure that the installed shut-off valves in the suction (inlet) and pressure (outlet) lines are completely open during operation. The pump must never be allowed to run with shut-off valves closed.

50 Pump Installation

8.5.5 Service and Maintenance

8.5.5.1 General Maintenance

Motor – The motor requires no maintenance. It has no

brushes or other frequently wearing parts.

CAUTION – If ball bearings need replacing, bearings with C3 air and high-temperature grease (approx. 180 °C / 360 °F) must be used!

Pump end – The pump mechanism (pump end) is lubricat-

ed only by water and requires no maintenance. It may wear after some years, especially if there are abrasive solids in the water. If sand accumulates in the pool or pipes as a result of normal pumping, it is best to take periodic measurement of the pump’s performance. A worn pump end can be easily replaced in the ﬁeld.

If the pump is running with seawater, the pump end must be cleaned periodically. The strainer basket must also be cleaned regularly to avoid excessive salt built-up.

8.5.5.2 Cleaning the Strainer

CAUTION – The strainer basket must be periodically emptied. A full or dirty strainer will impair the pump’s ﬂow rate and the ﬁltration.

(1) Shut down pump

(2) Close shut-off valves

(3) Open lid. If this is not possible by hand, use the

opening device (included in the delivery). Remove the strainer basket, clean and replace it.

(4) Close lid

(5) Open shut-off valves

(6) Restart pump

8.5.5.3 Use with salt water or sea water

In use, crystallized salt will build up in the pump. The rate of build-up (crystallization) will depend on the concentration of the salt and the temperature of the air and water. In salt water pools, the pump must be inspected and cleaned regularly by removing the drain plug and ﬁlter. When the salt deposits cannot be easily cleaned the pool professional must disassemble the pump and clean it. See chapter “8.5.5.4 Replacement of the Mechanical Seal” on page 51 for disassembly instruction.

8.5.5.4 Replacement of the Mechanical Seal

The sealing between the motor and the pump housing is done by means of a mechanical seal. It is normal for a few drops of water to seep in once in a while, especially during the break-in period. Depending on the nature of the water and the duration of operation, the mechanical seal may become leaky after some time. If the water penetrates con-tinuously, replace the complete mechanical seal with a new one. The seals must be replaced by a competent person.

Dismantling – Switch off the pump and disconnect it from the power supply. The mechanical seal always has to be replaced completely. To do so it is not necessary to dismount the complete pump – only the motor unit has to be removed from the housing by loosening the hexagonal socket screws.

Remove the fan cover of the motor by loosening the three screws. Put a screwdriver into the slot of the motor shaft (fan side), hold it and remove the impeller cap screw and the O-ring.

CAUTION – The impeller cap screw (with plastic head) has a left-handed thread. That means the screw must be turned clockwise (top view) to remove it.

The impeller is screwed onto the motor shaft (right-handed thread). Hold the motor shaft with the screw driver (fan side) and unscrew the impeller.

CAUTION – The impeller is secured by LOCTITE 480 (similar to Cyanoacrylate immediate glue).

Assembly – Apply some petroleum jelly at the edges of the

mechanical seal before pressing it in.

Follow these instructions in reverse for reassembly.

CAUTION – Before reassembly clean the surfaces of the components with alcohol or with a clean paper tissue.

Carefully lever the mechanical seal out of their ﬁxations with a screwdriver.

52 Pump Installation

8.6 Boost Surface Pumps

8.6.1 Placement and Foundation

WARNING – PS2 Boost pumps must not be submerged in or exposed to other sources of water, e.g. rain.

Operating noises – Make sure, by applying appropriate

measures, that the environment will not be impaired by any sound produced by the pump.

Space – During installation, make sure that there is enough space available to permit subsequent disassembly of the motor unit.

WARNING – The pump might heat up in operation. It must be installed on a non ﬂammable surface.

Connecting the pump to the foundation – Fastening

the pump to the foundation should be done exclusively by using bolts, threads or dowels in order to avoid blocking the removal of the motor unit.

CAUTION – Inlet- and outlet-pipes must be attached to the pump free of tension.

8.6.2 Pump Motor Wiring

L1 – L2 – L3 – ECDRIVE requires four-conductor (four-wire)

cable between the controller and the motor. The three wires L1, L2 and L3 carry power. The fourth wire carries ground. To reverse direction of rotation reverse any two phases.

CAUTION – No disconnect switches must be installed between motor and pump controller. Connecting the motor wire to the switched-on controller can cause damage. Such damage is excluded from the warranty.

CAUTION – starting the boost pump without setting the controller to boost mode will damage the pump. Such damage is excluded from the warranty.

Figure 19: LORENTZ boost pump

8.6.3 Installation Position

The pump may be mounted horizontally or vertically.

CAUTION – When installing the pump vertically, the pump head must be facing downwards.

Rigid mounting – is not required in most installations. In

a non battery system, the pump starts gradually and does not jerk with the start. In a battery system it will jerk slightly, but can be stabilized by mounting it to a small wooden board. The pump may be hung vertically on a rope. Observe the pump to ensure pipes are not overstressed or loosened as it starts.

CAUTION – Do not mount the pump directly to a wall or wood ﬂoor in your home. This will increase the noise.

Changing the pump head position – The pumps’ ﬁt-

tings can be changed to face sideways or downwards. The pump head may be rotated to a different position by loosening the clamp screws that secure the pump to the motor. Before installing the pump, inject water into the inlet and run the pump.

The pump may be installed either max. 3m below (gravity feed) or above (suction mode) the water level. Thereby the geodetic head between liquid level and pump inlet must not exceed 3m. The suction lift may be signiﬁcantly reduced by ﬂow resistance in the suction line (if the pipes are very long and/or insufﬁciently dimensioned).

54 Pump Installation

8.6.4 Filtering

CAUTION – Sand, clay, rust or other solids will cause rapid wear or immediate damage to the pump.

lf your water is free of any contamination, the LORENTZ PS Boost inline ﬁlter will provide sufﬁcient protection. The use of the LORENTZ intake strainer is recommended as third-party solutions may not be sufﬁcient. Since water conditions can be subject to change, the additional use of a ﬁlter is recommended.

A 30 inch intake ﬁlter/foot valve is necessary for pumps lowered into wells. For other installations an inline ﬁlter is best, installed close to the pumps’ intake. lf ﬁlters are expected to clog often, maintenance may be minimized by plumbing two or more ﬁlters in parallel. The inline ﬁlter has a clear bowl so its condition may be observed.

CAUTION – Have replacement cartridges ready.

Filter cartridges are available at retailers and local wa-

ter system suppliers. LORENTZ recommends the use of 10-20-micron “spun polypropylene” type ﬁlters. Carbon taste and odor cartridges have less capacity for dirt, more resistance to ﬂow, and are more expensive to use. Use them only if you have taste and odor problems.

A ﬁlter cartridge may look clean and still be clogged, due to ﬁne silt embedded in the ﬁbres. If the pump becomes increasingly noisy over time, it is usually due to a clogging ﬁlter cartridge. On the other hand a cartridge that looks discoloured may not be clogged. As long as the pump runs quietly, the ﬁlter is okay to use. The pump noise is an indicator for the need to change cartridges.

Iron pipes or ﬁttings will introduce abrasive rust particles if installed on the intake side of the pump. Dirt is also introduced as pipe joints are assembled, especially in a trench.

CAUTION – Make sure inlet lines and ﬁttings are ﬂushed clean before attaching them to the pump.

The inline ﬁlter may have a red push button valve to release pressure for maintenance. If the ﬁlter is placed more than a few feet above the water source (at lowest level) the suction may open the valve and introduce air. Prevent this by sealing the surrounding area of the push button with silicone sealant or epoxy, or replace the button with a nut, tightened down.

8.6.5 Plumbing Design

CAUTION – New pumps are covered with foam plugs to prevent contamination. Remove the foam plugs before connecting pipes.

CAUTION – Handle the pump with caution, never use force on it.

Minimize suction lift – to max. 3 m total pressure loss

(2 m for pumps with ﬂow rate greater than 400 l/h (105 US Gal)). The less suction lift, the more reliable and quiet the pump will be. The motor may not be submerged, this will damage the pump.

Intake pipe – The intake pipe may run any reasonable horizontal distance, although it is best to keep it short. Use large pipe for the intake (1 to 1 ½” for larger booster pumps). Slope the intake line from the water source up towards the pump. Avoid humps in the intake line that cause air pockets which can block the ﬂow.

CAUTION – Avoid leaks in the suction line. The pump will prime insufﬁciently or not at all.

The intake pipe must be sized generously to avoid high pressure drop at peak ﬂow rate, or the pump will be noisy and will wear rapidly.

Use pipe reducer ﬁttings to adapt the pumps’ inlet or outlet to larger pipe size where necessary. Larger pipe sizing does not have a negative effect.

CAUTION – The intake must not be restricted by undersized pipe, excessive suction lift, or a clogged ﬁlter.

CAUTION – Excessive suction at the pump intake causes cavitation, resulting in noise and rapid pump wear.

CAUTION – Do not use thin wall hose or soft tubing on the pumps’ intake. It may collapse under suction and restrict the ﬂow.

CAUTION – Do not use polyethylene pipe for the suction side. It is prone to leakage at the ﬁtting.

Inline ﬁlter – Inline ﬁlters should be mounted horizontal-

ly and as low as possible. This prevents any air trapped from blocking the water ﬂow.

Foot valve – The foot valve is a check valve installed at the water intake. It is required in any situation where the pump is located higher than the lowest water level of the water source. A high quality spring loaded type is recommended to avoid loss of prime. A check valve allows water to ﬂow one way only.

56 Pump Installation

8.6.6 Freeze Protection

Priming the pump – Priming a pump means complete-

ly ﬁlling its intake and suction line with water. This must be done if the pump is mounted higher than the water source. A removable plug or a valve must be installed at the highest point in the suction plumbing. Prime the pump and intake line by pouring water into the opening until it is ﬁlled completely. Your foot valve prevents loss of prime by not allowing water to ﬂow back into the water source. The pump will create sufﬁcient vacuum to self-prime to around 3 m/10 ft (less at high elevations), but only when it is in new condition and wet inside. A priming plug is always recommended if the pump is installed above the water source. Using a good quality ball valve instead of a plug is recommended, especially if frequent priming is expected.

Check valve at the pump outlet – A check valve at the pump outlet is required if there is more than a 10 m/30 ft lift above the pump, or in any pressurizing system. This allows a more easy start of the pump. It also prevents back ﬂow when changing ﬁlter cartridges.

Pipe unions – If you run rigid piping (copper or PVC) directly to the pump, unions are required. Unions make pump replacement easy, without the need to cut and re-solder or re-glue the pipe. “Copper Flex Connectors” commonly used for water heaters may be used instead.

Figure 20: LORENTZ boost pump installation kit

CAUTION – The pump must be protected from freezing. Freezing may damage the pump.

CAUTION – When insulating the pump for freeze protection the motor must be excluded to prevent overheating.

9 Pump Accessories Installation

CAUTION – To avoid multiple starts of the pump in twilight conditions, the Sun Sensor module must be installed and conﬁgured for all PS2-1800 CS-F and all PS2-4000 pump systems. Operating without a Sun Sensor module can lead to increased wear or damage to the pump. Such damage is excluded from the warranty.

CAUTION – Never let the pump run dry. Dry running will damage the pump and void the warranty. LORENTZ requires a dry run protection for every pump system.

CAUTION – Installing a surge protector at all switch inputs is recommended, damaged inputs due to electric surges are not covered by the warranty.

Figure 21: Well probe ﬁxing

9.1 Well Probe

The well probe contains a mechanical ﬂoat with a magnet inside. When the probe is submerged, the ﬂoat rises, and the magnet actuates a switch. The switch closes (makes contact) to indicate the presence of water. If the water level drops below the probe, the ﬂoat drops, and the switch opens (breaks contact): The controller will stop the pump. When the water level recovers and the switch closes again, the controller will delay the restart for 15 minutes for the water level to recover. To force a quick restart, turn the controller off, then on again. The switch is sealed, so the contacts never touch the water.

Submersion depth – The maximum submersion depth is 50 meters.

Fixing – Along with the probe two cable ties are provided. For a pump that is to be installed in a vertical position, clamp the probe to the pipe just above the pump outlet, as shown in “Figure 21: Well probe ﬁxing”. Splice the two wires of the probe using the splice kit components that are packed with the probe. The assembly procedure is the same as the main pump splice.

Wiring to the controller – The well probe must be wired to the controller at terminal 1 and 2, cf. “7.6.3 Pump Accessories Wiring” on page 27.

Potential problems with the well probe in surface water – The probe has a moving ﬂoat. It is highly resistant

to deposits and debris. However, the ﬂoat can become stuck where algae or water creatures are present in surface water..

58 Pump Accessories Installation

Possible solutions are:

 Fix the probe independently of the pump and pipe

(clamped to a weight, but not to the drop pipe). This way, it can be pulled out for inspection or cleaning without the need to lift the pump. (This may not be feasible if the well casing is smaller than 6 in)

 Pull the probe out periodically (with the pump, if neces-

sary) for testing and inspection. The pump should stop a few seconds after the probe leaves the water.

 Wrap the probe in a protective screen (ﬁberglass

window screen, for example).

 Use a different type of ﬂoat switch. You can use any

switch that makes contact on rise (normally open).

 Use an encapsulated switch instead of the well probe

if there is enough space for it to operate properly, for example the LORENTZ ﬂoat switch.

CAUTION – Never let the pump run dry. Dry running will damage the pump and void the warranty. LORENTZ requires a dry run protection for every pump system.

CAUTION – The well probe must be positioned vertically, within 10°. If the pump is not to be installed vertically, ﬁnd an alternative way to mount or suspend the probe, so that it is located higher than the pump, and in a vertical position.

9.2 Float Switch (Full Tank Shut-off)

We recommend the use of a ﬂoat switch or other means to prevent overﬂow of your tank. This will stop the pump when the tank is full, then reset when the level drops. This conserves ground water, prevents overﬂow, and eliminates unnecessary pump wear. PS2 controllers allow the use of a small signal cable to a remote ﬂoat switch, even if the tank is a long distance away.

Float switch requirements:

(1) A switch must be used, not wet electrodes. (2) The preferred system requires a ﬂoat switch to OPEN

contact on rise to turn the pump OFF. This is called “normally closed” (N.C.).

Float switch cable requirements:

(3) Two wires are needed. (4) Minimum wire size 1mm² / AWG 18. This is good for a

distance as far as 600 m / 2,000 ft. (5) The cable must be suitable for its environment. (6) If it must run a long distance, use twisted-pair shielded

cable to reduce the chance of damage from light-

ning-induced surge.

Figure 22: Float switch scheme

Grounding shielded ﬂoat switch cable – If you use shielded cable, connect the shield to ground at the controller only. Do not ground the shield at the ﬂoat switch. This will reduce surges induced by nearby lightning.

Operation of the ﬂoat switch system – When the water level is high, the ﬂoat switch will stop the pump. The remote switch indicator on the controller will light up. When the water level drops, the ﬂoat switch will signal this to the controller. The indicator light will turn off, and the pump will restart if sufﬁcient power is available.

Wiring to the controller – The ﬂoat switch must be wired to the controller at terminal 3 and 4, cf. “7.6.3 Pump Accessories Wiring” on page 27.

Manual remote control switch – The ﬂoat switch circuit can be used with a manual switch to turn the pump on and off from a distance. Use any simple on/off switch available from an electronic supply, electrical supply, or hardware store (it only carries low voltage, very low current). Wire it according to the illustration above, for a normally closed ﬂoat switch.

9.3 Water Meter

For information on the water meter installation, please refer to the manufactures manual. Pay attention to the installation position, ﬂow direction and the calming section.

Basic rule: The water meter should have 10 nominal diameters straight pipe ahead of the meter and 5 nominal straight pipe diameters after to ensure proper ﬂow through the meter

9.4 Sacriﬁcial Anode

The LORENTZ Sacriﬁcial Anode is designed for use with LORENTZ pump ends. Where solar pump ends operate in aggressive water conditions acidic water can attacks the passive layer of the high quality-steel pump end. This corrosion reduces the life time of the product. The LORENTZ Sacriﬁcial Anode contributes to the protection of the pump system from this type of corrosion and extends the pumps life.

For further information about the Sacriﬁcial Anode please refer to the COMPASS datasheet.

Figure 24: LORENTZ Sacriﬁcial AnodeFigure 23: LORENTZ Water Meter

9.5 Liquid Level Sensor

9.6 Pressure Sensor

The LORENTZ range of liquid level sensors use pressure to measure the level or water in a well or tank. The sensors can be used for long term water level monitoring and also for pump control in applications where a well probe cannot be used.

For further information about the Level sensor please refer to the COMPASS datasheet.

Figure 25: LORENTZ Liquid Level Sensor Figure 26: LORENTZ Pressure Sensor

The LORENTZ range of liquid pressure sensors are used to measure the pressure in a pipe. The sensors are commonly used to measure the pressure at a well head or feeding into irrigation systems.

For more information about the pressure sensor please refer to the COMPASS datasheet. Ensure that the pressure sensor is suitable for your application regarding pressure range and temperature resistance.

62 Pump Accessories Installation

9.7 Sun Sensor module

The LORENTZ Sun Sensor module allows an irradiation level to be set at which the pump is switched on. This means the Sun Sensor module will not allow the pump to start until there is sufﬁcient irradiation to power the pump to the point of water delivery.

The PS2-1800 and PS2-4000 controllers are supplied with a special small 1.5 Wp PV module (pre-wired for crimping). This PV module is used to measure the solar irradiation and allows you to set irradiation dependent START / STOP values for the pump.

These settings can only be done via LORENTZ PumpScanner. (Please check LORENTZ partnerNET and the “PS DataModule and PumpScanner” manual).

Correct Sun Sensor module settings are given in the COMPASS report, subject to correct parameters. These settings must be checked on site to make sure that the parameters entered in COMPASS match the conditions on site and that the Sun Sensor module is working as intended.

Mount the Sun Sensor module with the same alignment as the solar array that powers the pump system. For example, if the solar array is tilted at an angle of 20°, the PV panel for the Sun Sensor module should be tilted exactly the same. You can ensure this by mounting the PV module on the frame of the PV module array.

CAUTION – Do not use any other PV module than the one available from LORENTZ or the PS2 controller will be damaged.

CAUTION – Voltage reversal of the Sun Sensor module will lead to damage of the controller.

Figure 27: LORENTZ Sun Sensor module

9.8 Surge Protector

9.9 PV Disconnect with Lightning Surge Protection

CAUTION – Installing a surge protector at all well probe and remote switch sensor inputs is recommended, damaged inputs due to electric surges are not covered by the warranty.

CAUTION – Surge protectors provide an extended protection, not a guaranteed safety. Damages caused by electric surges are not covered by warranty.

CAUTION – When installing surge protectors, correct polarity must be ensured.

Surge protectors are designed to protect electrical devices from voltage spikes. The surge protectors are to be connected in series to the sensor/input, ideally within the PS controller case. It can only be used for well probe, remote switch and water meter terminals. It can not be used for analog input 1, 2, water sensor and the relay output. For more information on the surge protector please refer to the datasheet in COMPASS.

The LORENTZ PV Disconnect series is a PV connection box with an integrated disconnect switch and optional integrated lightning surge protector. The box is designed to connect one PV module string (6 strings for the 440-40-6) with the pump controller by using the terminal clamps located inside the box. The DC-rated disconnect switch is used as a manual circuit breaker between the solar array and the load. This switch is easily accessible by opening the hinged lid at the bottom spring lock.

The use of a properly sized DC disconnect switch is an important safety measure and obligatory for a professional installation of a solar pumping system. The switch must be installed between the solar generator and the pump controller. It must meet the electrical requirements of the connected devices. The PV Disconnect has been designed to cover the range of PS pump systems PS2-150 to PS2-4000.

Optionally a lightning surge protection device can be purchased from LORENTZ that ﬁts into a pre-built hole of the PV Disconnect. It requires proper grounding to fulﬁl its protective function. There are a number of different devices available to suit the voltage level of each controller type.

For more information on installing the PV Disconnect please refer to the PV Disconnect manual.

72 Troubleshooting

12 Troubleshooting

Please read this section carefully in case you experience any problems with the pump system and follow the checklists. Should technical support by LORENTZ become necessary, always provide the model and serial numbers.

12.1 Pump does not run

Most problems are caused by either wrong cable connections (in a new installation) or failed connections, especially insufﬁciently tightened cables that come loose from a terminal. Please check the wiring. The System status light will indicate that the system is switched on and a power source is connected to the controller. It indicates that voltage is present but in a solar-direct system there may not be sufﬁcient power to start the pump. In this case it will attempt a restart every 120 seconds.

12.2 Pump attempts a Restart every 120 Seconds

The controller will emit a low noise as it tries to start the pump. The pump will start to turn or only vibrate a little.

(1) There may be insufﬁcient power reaching the controller.

A solar-direct (non-battery) system should start if there is sufﬁcient sun to cast a slight shadow. A battery system should start if the supply voltage is higher than what is listed in “Set points for low voltage disconnect” on page 29.

(2) If the pump was recently connected (or reconnected)

to the controller, it may be running in reverse direction due to a wiring error.

(3) If the motor shaft only vibrates but does not turn, it

may have power on only two of the three motor wires. This will happen if there is a broken connection or if you accidentally interchanged one of the power wires with the ground wire.

(4) The pump or pipe may be blocked by mud, clay, sand

or debris

CAUTION – if the pump is blocked, it has to be cleaned. Repeated starting of a blocked pump may cause damage to the motor. This will void the warranty.

12.3 Flow Rate is to low

Check if the pipeline dimensions are correct as pressure losses will reduce the ﬂow. Ensure that there is no leakage in the pipeline.

12.4 General checklist

Check the PV generator

Make sure the PV generator is facing the sun and there is no partial shading of the array. A partial shading of as little as 10% of the arrays’ surface can stop the pump.

Check all wires and connections

Carefully check for improper wiring (especially in a new installation) and wiring condition. Wires are often damaged by animals if they are not enclosed in conduit (pipe). Pull on wires slightly to check for failed connections.

Check the controller

(1) Loosen the screws from the front of the controller to

access the terminal block where the wires connect.

(2) Check for a burnt smell. This will indicate a failure

of the electronics. Look for burnt wires, bits of black debris, and any other signs of lightning damage.

(3) Inspect the grounding wires and connections. Most

controller failures are caused by an induced surge from nearby lightning where the system is not effectively grounded. Ground connections must be properly made and free of corrosion.

74 Troubleshooting

Check the dry running protection

If the controller indicates “source low” when the pump is submerged in water or draws from a sufﬁcient water source, check the dry running protection system. The probe is mounted on, or near the pump. If inspection is not feasible, you can measure the well probe for continuity with a multimeter. The Well Probe should show continouity when it is submerged in the water.

Check the ﬂoat switch

If the controller indicates “remote switch” when the storage tank is not full, inspect the ﬂoat switch system. If your system has a ﬂoat switch, it will be mounted in the tank. If inspection is not feasible, you can bypass the switch or test it electrically.

Force a quick start

If you restore a connection or bypass the probe or ﬂoat switch, there is no need to wait for the normal time delay. Manually switch the on/off switch (or the power source) off and on to reset the system. The pump should start immediately if sufﬁcient power is present.

If the pump responds to the bypass tests but not to the ﬂoat switch, the wires may be shorted (touching each other) or open (broken) or the switch may be stuck with debris, or out of its correct position.

Quick checklist

Make sure

(1) the pump is suited for the total lift that is required.

(2) the “max. RPM” adjustment in PumpScanner is not the

reason for perceived low pump performance.

(3) the solar array is receiving sufﬁcient sun light without

shading on the modules, the PV generator is oriented properly and tilted at the correct angle. Inspect and test the PV generator circuit and the controller output, as stated. Take notes of your measurements.

(4) all wires and pipe runs are sized adequately for the

respective distance.

(5) there is no leak in the output pipe from the pump.

Could the issue not be resolved, please raise a service case with LORENTZ including the service support forms available on partnerNET, model and serial numbers and your measurements.

2 Réception, stockage et

manipulation

Vériﬁer à la réception que l’emballage est intact et non endommagé. Pour toute anomalie détectée, contacter le fournisseur.

Les pompes LORENTZ sont expédiées de l’usine dans un emballage approprié dans lequel elles doivent rester jusqu’à leur installation. Manipuler la pompe avec soin et éviter tout choc et impact inutiles.

Tout stockage intermédiaire prolongé dans un environnement se caractérisant par une forte humidité et des températures variables doit être évité. L’humidité et la formation de condensation peuvent endommager les parties métalliques. Une non-conformité peut annuler la garantie. Il est recommandé de stocker les pièces dans une pièce fermée et sèche.

Le moteur, la tête de pompe et le contrôleur peuvent être stockés (inutilisés) dans une plage de -20°C à +65°C (-4°F à +149°F). Les composants ne doivent pas être exposés à la lumière directe du soleil.

3 Spéciﬁcation des produits

3.1 Généralités

Les systèmes de pompe solaires de surface et immergées LORENTZ sont conçus pour fournir efﬁcacement d’importants volumes d’eau, et ce uniquement avec de l’énergie solaire. Ils sont habituellement utilisés pour des projets d’irrigation et pour des applications d’eau potable à grande échelle où ils répondent de manière sûre aux exigences les plus pointues, d’un point de vue économique, sans générer de pollution et sans raccord au réseau ou générateur diesel.

Un système de pompe solaire type est composé d’un générateur pour panneaux PV, d’une pompe et d’un contrôleur de pompe solaire. Reposant sur le principe qu’il est plus efﬁcace de stocker de l’eau plutôt que de l’électricité, le système ne possède aucun dispositif de stockage d’énergie tel qu’un accumulateur électrique comme dans un système de pompe solaire standard.

Le générateur PV, accumulation de plusieurs modules PV raccordés en série et en parallèle, absorbe le rayonnement solaire et le transforme en énergie électrique, fournissant de l’énergie à l’ensemble du système. Le contrôleur de la pompe contrôle et règle le fonctionnement du système; il paramètre la fréquence de sortie en temps réel en fonction de la variation de l’intensité d’ensoleillement, aﬁn d’obtenir une optimisation de puissance (MPPT).

Chaque système de pompe LORENTZ est composé d’une tête de pompe, d’un moteur de pompe et d’un contrôleur. Ce concept modulaire garde tous les composants électroniques au-dessus du niveau du sol, même pour les pompes immergées, aﬁn de faciliter l’entretien et de réduire le coût d’exploitation.

4 Conditions de fonctionnement

Conditions ambiantes: les systèmes de pompe PS2

peuvent fonctionner jusqu'à une altitude de 3000m au-dessus du niveau de la mer et à une température ambiante de 50°C maximum. Si la température atteint la valeur limite, l'alimentation électrique est automatiquement réduite. Le contrôleur PS2 a été conçu pour une utilisation dans des environnements correspondant au degré de pollution3, conformément à la norme IEC-664-1: Présence d'une pollution conductrice ou d'une pollution sèche, non conductrice, qui devient conductrice par suite de la condensation qui peut se produire.

Liquide: les pompes centrifuges et à rotor hélicoïdal (HR) LORENTZPS2 peuvent être utilisées pour l’approvisionnement en eau potable, les abreuvoirs et les systèmes d’irrigation ne contenant pas de particules solides ou à longues ﬁbres d’une taille supérieure à celle de grains de sable, d’un diamètre maximal de 2mm. La teneur en sable maximale autorisée est de 50ppm; une teneur plus élevéeréduirait considérablement la durée de vie de la pompe enraison de l’usure. La teneur en sel maximale est de 300-500ppm à une température maximale de 30°C/85°F. Les défectuosités dues au pompage d’autres liquides ne sont pas couvertes par la garantie.

Les pompes de piscine LORENTZPS2 peuvent être utilisées dans de l'eau chlorurée, de l'eau de mer et de l'eau salée. Lorsqu’elle est utilisée dans des piscines à eau salée et eau de mer, la pompe doit être inspectée et nettoyée régulièrement.

Les pompes LORENTZPS2BOOST peuvent être utilisées pour les applications d’eau propre uniquement. L’eau ne doit contenir aucune particule abrasive. Il est vivement recommandé d’installer un ﬁltre d’entrée pour protéger la pompe de toute intrusion de poussière. Se reporter à «8.6.4 Filtration» page54 pour plus d’informations.

Température du liquide: selon le type de système de pompe LORENTZ, différentes exigences s’appliquent aux températures du liquide:

PS2 centrifuge immergée – La température maximale du liquide pour les pompes centrifuges immergées est de

+50°C (122°F).

PS2 centrifuge de surface – La température maximale

du liquide pour les pompes centrifuges de surface est de

+70°C (158°F).

PS2 centrifuge de piscine – La température maximale du liquide pour les pompes de piscine est de +60°C (140°F).

PS2Boost de surface – La température maximale du liquide pour les pompes Boost est de +80°C (176°F).

PS2 à rotor hélicoïdal (HR) immergée – La conception

et la fabrication de pompes à rotor hélicoïdal pour une petite plage de température de liquide sont importantes pour assurer la plus grande efﬁcacité possible. Les pompes hélicoïdales PS2 de LORENTZ sont disponibles dans cinq classes de températures:

Classe de temp. 0: 0 – +10°C (32 – 50°F) Classe de temp. 1: +10 – +20°C (50 – 68°F) Classe de temp. 2: +20 – +30°C (68 – 86°F) Classe de temp. 3: +30 – +40°C (86 – 104°F) Classe de temp. 4: +40 – +50°C (104 – 122°F)

Les pompes ont une marge de tolérance de ±2°C (±3,6°F) pour chacune des plages de température, sauf pour la plus faible température autorisée de 0°C.

La classe de températures est indiquée dans la dénomination de l'unité de pompage, se reporter au chapitre «3.4 Dénomination» page8. Le système de pompe ne doit fonctionner que dans la plage de températures spéciﬁée à la commande.

AVERTISSEMENT – Les têtes de pompe etles unités de pompage PS2-200HR doiventtoujours être commandées pour laclasse de températures immédiatement supérieure, pour éviter tout problème de démarrage dans des conditions de rayonnement faibles.

AVERTISSEMENT – Faire fonctionner la pompe hors de la plage de températures spéciﬁée peut réduire son efﬁcacité et/ oul’endommager, et peut annuler lagarantie.

INFORMATION – En raison de la précision des marges de tolérance des pompes LORENTZHR, il peut être recommandé d'employer une pompe correspondant àune classe de température supérieure àlatempérature réelle de l'eau. Ces recommandations se basent sur l'expérience accumulée avec des sources d'eau qui peuvent contenir des impuretés et desparticules solides en fonction de leur situation géographique.

6 Schémas de conception et de dimensionnement d’un système de pompe

6.1 Dimensionnement d’un système de pompe

Pour dimensionner et installer d’une manière professionnelle un système de pompage d’eau, plusieurs variables doivent être prises en compte selon le type de pompe et l’application:

Hauteur statique – Hauteur verticale du niveau dynamique de l’eau jusqu’au plus haut point de livraison.

Hauteur d’aspiration – Hauteur verticale du niveau de l’eau à l’entrée de la pompe à l’endroit où le niveau de l’eau est au-dessous de l’entrée de la pompe.

Pertes de pression – Perte de pression de l’eau due à la longueur du tuyau et au frottement causé par le matériau du tuyau et les éléments ajoutés à la tuyauterie tels que coudes, vannes.

Pour un pompage d’eau solaire, il est aussi nécessaire de connaître le rayonnement local pour calculer la puissance disponible chaque jour et l’effet sur le débit d’eau.

Pour gérer facilement et prendre en considération les différentes variables, LORENTZ recommande vivement de dimensionner des systèmes de pompe avec LORENTZ COMPASS, le logiciel de planiﬁcation des pompes solaires.

COMPASS est l’outil de LORENTZ pour concevoir, planiﬁer et spéciﬁer les systèmes de pompes solaires. Il peut être téléchargé par tous les partenaires

LORENTZ sur partnerNET.

COMPASS est un outil qui s’utilise sur PC permettant de spéciﬁer simplement les systèmes de pompes solaires en temps réel. Il se base sur les données météorologiques de la NASA et utilise des algorithmes précis pour les calculs même les plus complexes.

En sélectionnant l’emplacement dans une liste de plus de 250000villes, en saisissant la hauteur manométrique et le volume d’eau nécessaire par jour, le logiciel indiquera automatiquement les systèmes de pompes adaptés et la taille nécessaire du générateur PV.

Pour des situations plus complexes, COMPASS propose des fonctionnalités telles que le calcul de la hauteur d’aspiration ou de la perte de pression spéciﬁque au type de tuyau.

REMARQUE – Toujours s’assurer que les valeurs utilisées pour le dimensionnement avec COMPASS correspondent bien aux conditions sur site. Des paramètres incorrects peuvent entraîner un rapport de dimensionnement erroné.

7.1 Généralités

ATTENTION – Tous les raccordements électriques doivent être effectués par desspécialistes qualiﬁés uniquement.

ATTENTION – Ne pas démonter le contrôleur lorsqu’il est branché à l’alimentation électrique! Avant toute installation, maintenance ou inspection, attendre au moins deux minutes après avoir débranché le contrôleur de l’alimentation électrique.

AVERTISSEMENT – Pour éviter des démarrages à répétition de la pompe dansdes conditions de luminosité changeantes, le module SunSensor doit être raccordé et conﬁguré sur tous les systèmes de pompage PS2-1800CS-F et PS2-4000. Son fonctionnement sans module SunSensor peut entraîner une usure accrue ou un endommagement de lapompe. Ce type d'endommagement n'est pas couvert par la garantie.

AVERTISSEMENT – Ne jamais faire tourner

la pompe à sec. L’utilisation de la pompe àsec endommagera cette dernière et annulera la garantie. LORENTZ exige une protection contre le fonctionnement à

secpour chaque système de pompe.

Pour plus d’informations sur les accessoires obligatoires et leur installation, se reporter à «7.6.3 Câblage des accessoires de la pompe» page27 et «9 Installation des accessoires de lapompe» page57.

Le contrôleur est un déchet industriel qui doit être mis au rebut en conséquence. Certains composants sont susceptibles de produire des gaz nocifs et toxiques.

Un kit de prise est disponible séparément du contrôleur encas d'utilisation de ﬁches mâles.

Figure2: contrôleur PS2

Sectionneur CC

Conduite électrique

Tout système de pompe solaire doit être équipé d’un sectionneur CC correctement dimensionné. Le sectionneur

doit être installé entre le générateur PV et le contrôleur. Ildoit satisfaire aux exigences suivantes:

 valeur nominale minimale selon le «Tableau1:

puissance nominale minimale du sectionneur CC» page17

 courant continu nominal selon le courant maximum

Il est recommandé d’utiliser une conduite électrique. Nous recommandons l’utilisation d’une conduite (tuyau) électrique pour protéger le câblage extérieur des intempéries, des activités humaines ou des dommages causés par des animaux. En l’absence d’une telle conduite, utiliser des câbles de qualité élevée pour usage extérieur. Utiliser également des presse-étoupes d’étanchéité anti-traction au niveau de l’entrée des câbles dans la boîte de jonction.

Section

Pour les câbles de signaux, la section minimum est de 1,5mm2 (AWG16). Pour les câbles d'alimentation, la section minimum est de 2,5mm2 (AWG14). Comparer ses sections de câble aux rapports de dimensionnement de LORENTZCOMPASS. Les câbles doivent être blindés de façon à répondre aux exigences en matière de compatibilité électromagnétique.

Pour un usage à l'extérieur, il est recommandé d'employer des câbles répondant aux exigences de la norme 60245 IEC66. Pour un usage en intérieur, le type de câble recommandé est déﬁni dans la norme 60245 IEC 57. Le monteur devra tenir compte des spéciﬁcités, réglementations et codes de bonne pratique locaux et employer un câble qui répond à ces exigences.

7.4 Mise en place du contrôleur

Le contrôleur doit rester protégé de l’eau, de l’humidité et des animaux. Son boîtier doit donc toujours être étanche. Positionner le contrôleur dans un endroit sec et sufﬁsamment ventilé.

Placer le contrôleur à proximité du panneau solaire, pas de la pompe, pour réduire le risque de dommages dus à la foudre. Les circuits d’entrée du contrôleur sont plus sensibles aux surtensions que ceux de sortie. Il est ainsi plussûr de limiter la longueur du câblage d’entrée.

Les équipements électroniques présentent une plus grande ﬁabilité lorsqu’ils sont protégés contre la chaleur. Placer le contrôleur à l’ombre du soleil de midi. La partie sous le générateur PV constitue un emplacement idéal. En l’absence d’ombre, boulonner une plaque de métal derrière le contrôleur et la plier de sorte à former un écran au-dessus de celui-ci. Cette protection est particulièrement importante dans les zones climatiques très chaudes. Une température excessive est susceptible d’activer la protection thermique du contrôleur, provoquant une réduction de la consommation électrique ou l’arrêt du contrôleur. Le boîtier du contrôleur peut atteindre des températures élevées lorsqu’il fonctionne à des températures ambiantes importantes. C’estnormal et cela ne réduira pas la durée de vie attendue du contrôleur ou de ses composants.

7.5 Exigences de montage, d’espace et de ventilation

Les contrôleurs PS2 peuvent être montés côte à côte.

Pour la mise à terre du couvercle frontal, les vis du couvercle doivent être serrés avec un couple de serrage minimal de 2 Nm.

Les contrôleurs PS2 ne disposent pas de ventilateur; ils sont refroidis par convection d’air. Il est vivement conseillé de ne pas installer le contrôleur dans un coffret supplémentaire. Si un coffret supplémentaire est nécessaire, un débit d’air vertical sufﬁsant (de bas en haut) doit être garanti pour que le refroidissement soit sufﬁsant.

Les contrôleurs PS2 ont un système de ﬁxation par des trous de serrures pour simpliﬁer le montage sur les surfaces appropriées. Pour le montage aux poteaux et aux structures similaires le PS2 est compatible avec les accessoires de supports de ﬁxations LORENTZ pour un maximum de commodité.

Lorsque vous ﬁxez le contrôleur PS2 avec les accessoires de supports de ﬁxation LORENTZ, serrez les vis diagonalement et uniformément.

AVERTISSEMENT – ne serrez pas trop les vis de montage au boîtier PS2 quand vous utilisez les accessoires de supports de ﬁxation pour éviter d’endommager le boîtier du contrôleur PS2.

AVERTISSEMENT – lorsque vous utilisez les supports de ﬁxation, pour les systèmes de haute performance et/ou dans les régions avec des températures ambiante élevées, il faut installer une plaque arrière entre le contrôleur et les supports de ﬁxation pour empêcher l’effet d’entonnoir des ailettes de refroidissement. Le fonctionnement sans plaque arrière peut mener à un refroidissement insufﬁsant qui entraînera une performance réduite.

Pour connaître les dimensions du contrôleur, se reporter au «Tableau3: dimensions d’installation du contrôleur PS2» page20.

7.6 Câblage du contrôleur

ATTENTION – Tous les raccordements électriques doivent être effectués par des spécialistes qualiﬁés uniquement. Une manipulation effectuée par une personne non qualiﬁée peut entraîner un choc, des brûlures ou la mort.

ATTENTION – Haute tension. Ne jamais travailler sur un système sous tension ou dans les deux minutes suivant son débranchement aﬁn d’éviter tout chocélectrique.

Avant de commencer à travailler sur le système électrique, s’assurer que tous les composants sont débranchés de la source électrique. Ne pas travailler sur des composants lorsqu’ils sont sous tension et attendre deux minutes après les avoir mis hors tension. Le contrôleur a besoin de temps pour se décharger.

Mettre le système sous tension uniquement lorsque toutes les tâches sont terminées.

AVERTISSEMENT – Le contrôleur doit uniquement être mis sous tension après uncâblage correct, à défaut de quoi il risquerait d’être endommagé.

AVERTISSEMENT – Ne pas installer de sectionneur sur les câbles d’alimentation entre le moteur et le contrôleur de la pompe. Le fait de brancher les câbles du moteur à un contrôleur sous tension peut entraîner des dommages irréparables. Cetype d'endommagement n'est pas couvert par la garantie.

AVERTISSEMENT – Systèmes sans batterie uniquement – Ne pas raccorder d’équipement électrique supplémentaire (hors contrôleur de pompe LORENTZ) au générateur PV. L’ajout d’un chargeur de batteries, d’un contrôleur de suivi de trajectoire, d’un chargeur de clôture électrique ou de tout autre appareil parallèlement aux systèmes LORENTZPS2 est de nature à interférer avec le fonctionnement du contrôleur et empêcher son bon fonctionnement.

AVERTISSEMENT – Mesurer la tension avant de relier l’alimentation au contrôleur. La tension (circuit ouvert) ne doit pas dépasser l’entrée c.c. max. (se reporter au«Tableau2: données techniques du contrôleur PS2» page18).
