4.1.6 Outdoor installation

The enclosure class of MLE motor is a NEMA 3 rating. If you install the motor outdoors, provide the motor with a suitable cover and open the drain holes to avoid condensation on the electronic components. See figs 2 and 3.

When fitting a cover to the motor, observe the guideline in section 4.1.5 Ensuring motor cooling.

The cover must be sufficiently large to ensure that the motor is not exposed to direct sunlight, rain or snow. Grundfos does not supply covers. We therefore recommend that you have a cover built for the specific application. In areas with high humidity, we recommend that you enable the built-in standstill heating function. See section 7.21 "Standstill heating".

Fig. 2 Examples of covers (not supplied by Grundfos)

In order to maintain the UL mark, additional requirements apply to the equipment. See Appendix, page 66.

4.1.7 Drain holes

When the motor is installed in moist surroundings or areas with high humidity, the bottom drain hole must be open. The enclosure class of the motor will then be lower. This helps prevent condensation in the motor as the motor becomes self-venting, and it allows water and humid air to escape.

The motor has a plugged drain hole on the drive side. You can turn the flange 90 ° to both sides or 180 °.

Fig. 3 Drain holes

4.2 Electrical installation

values stated on the nameplate. The wires in the motor terminal box must be as short as possible.

Excepted from this is the separated ground conductor which must be so long that it is the last one to be disconnected in case the cable is inadvertently pulled out of the cable entry.

In order to avoid loose connections, make sure that you have pressed home the terminal block for L1, L2 and L3 in its socket when you connect the supply cable.

For maximum backup fuse, see section 10.4.1 Supply voltage.

4.2.4 Additional protection

DANGER

Electric shock

Death or serious personal injury

- Only use residual-current circuit breakers (ELCB, GFCI, RCD) of type B.

The residual-current circuit breaker must be marked with the following symbol:

If you want to supply the motor through an IT network, make sure that you have a suitable motor variant. If you are in doubt, contact Grundfos.

Corner grounding is not allowed for supply voltages above 3 x 480 V, 50/60 Hz.

power supply switch, backup fuses and additional protection

Fig. 7 Power supply connection, three-phase motors

The total leakage current of all the electrical equipment in the installation must be taken into account. You find the leakage current of the motor in sections 10.3.2 Leakage current and

10.4.2 Leakage current (AC).

This product can cause a direct current in the protective ground conductor.

Overvoltage and undervoltage protection

Overvoltage and undervoltage may occur in case of unstable power supply or a faulty installation. The motor is stopped if the voltage falls outside the permissible voltage range. The motor restarts automatically when the voltage is again within the permissible voltage range. Therefore, no additional protection relay is required.

The motor is protected against transients from the

TM05 3942 1812TM05 3495 1512

power supply according to EN 61800-3. In areas with high lightning intensity, we recommend external lightning protection.

Overload protection

If the upper load limit is exceeded, the motor automatically compensates for this by reducing the speed and stops if the overload condition persists.

The motor remains stopped for a set period. After this period, the motor automatically attempts to restart. The overload protection prevents damage to the motor. Consequently, no additional motor protection is required.

Overtemperature protection

The electronic unit has a built-in temperature sensor as an additional protection. When the temperature rises above a certain level, the motor automatically compensates for this by reducing the speed and stops if the temperature keeps rising. The motor remains stopped for a set period. After this period, the motor automatically attempts to restart.

Protection against phase unbalance

Three-phase motors must be connected to a power supply with a quality corresponding to IEC 60146-1-1, class C, to ensure correct motor operation at phase unbalance. This also ensures long life of the components.

4.2.5 Connection terminals

The descriptions and terminal overviews in this section apply to both single- and three-phase motors.

For maximum torques, see section Torques, page 64.

Connection terminals, LCSE and VLSE

LCSE and VLSE pumps have a number of inputs and outputs enabling the pumps to be used in advanced applications where many inputs and outputs are required.

The pumps have these connections:

• three analog inputs

• one analog output

• two dedicated digital inputs

• two configurable digital inputs or open-collector outputs

• Grundfos Digital Sensor input and output

• two Pt100/1000 inputs

• two LiqTec sensor inputs

• two signal relay outputs

7.4.1 "Constant pressure"

7.4.2 "Constant temperature"

Pump variant

"Constant pressure"

LCSE ● VLSE ●

We recommend this control mode if the pump is to deliver a constant pressure, independently of the flow in the system. See fig. 35.

Fig. 35 "Constant pressure"

This control mode uses the factory-fitted pressure sensor, if any, which measures the outlet pressure of the pump.

For pumps without a factory-fitted sensor, you must connect a pressure sensor to one of the analog inputs of the pump. You can set the pressure sensor in the "Assist" menu. See section

7.41 "Assisted pump setup".

Examples

• One external pressure sensor.

Pump variant

"Constant

LCSE* VLSE ●

* You can install LCSE with an optional pressure sensor for constant-pressure control.

The pumps have a factory default setting of gain (K time (T

) and integral

However, if the factory setting is not the optimum setting, you can change the gain and the integral time:

• Set the gain within the range from 0.1 to 20.

• Set the integral-action time within the range from 0.1 to 3600 seconds. If you select 3600 seconds, the controller functions as a P controller.

Furthermore, you can set the controller to inverse control. This means that if you increase the setpoint, the speed is

reduced. In the case of inverse control, you must set the gain within the range from -0.1 to -20.

General rules of thumb If the controller is too slow-reacting, increase the gain. If the controller is hunting or unstable, dampen the system by

reducing the gain or increasing the integral time.

7.15 "Limit-exceeded function"

Pump variant

LCSE ● VLSE ●

This function can monitor a measured parameter or one of the internal values such as speed, motor load or motor current. If a set limit is reached, a selected action can take place. You can set two limit-exceeded functions meaning that you can monitor two parameters or two limits of the same parameter simultaneously.

The function requires setting of the following:

"Measured"

Here you set the measured parameter which is to be monitored.

"Limit"

Here you set the limit which activates the function.

"Hysteresis band"

Here you set the hysteresis band.

"Limit exceeded when"

Here you can set if you want the function to activate when the selected parameter exceeds or drops below the set limit.

• "Above limit". The function is activated if the measured parameter exceeds the set limit.

• "Below limit". The function is activated if the measured parameter drops below the set limit.

"Action"

If the value exceeds a limit, you can set an action. You can select the following actions:

• "No action". The pump remains in its current state. Use this setting if you only want to have a relay output when the limit is reached. See section 7.9 "Signal relays" 1 and 2 ("

• "Warning/alarm". A warning is given.

•"Stop". The pump stops.

•"Min.". The pump reduces speed to minimum.

•"Max.". The pump increases speed to maximum.

"Limit-exceeded

function"

Detection delay

You can set a detection delay which ensures that the monitored parameter stays above or below a set limit in a set time before the function is activated.

Resetting delay

The resetting delay is the time from which the measured parameter differs from the set limit including the set hysteresis band and until the function is reset.

Example:

The function is to monitor the outlet pressure from a CRE pump. If the pressure is below 5 bar for more than 5 seconds, a warning must be given. If the outlet pressure is above 7 bar for more than 8 seconds, reset the limit exceeded warning.

The function requires that a LiqTec sensor has been fitted and connected to the pump.

When you have enabled the LiqTec function, it stops the pump if dry running occurs. Restart the pump manually if it has been stopped due to dry running.

"Dry running detection delay"

You can set the "Low-flow stop function" to these values:

•"Not active"

• "Energy-optimal mode"

• "High-comfort mode"

• "User-defined mode" ("Customised operating mode").

When the low-flow stop function is active, the flow is monitored. If the flow becomes lower than the set minimum flow (Q pump changes from continuous operation at constant pressure to start-stop operation and stops if the flow reaches zero.

), the

min

The advantages of enabling the "Low-flow stop function" are the following:

• no unnecessary heating of the pumped liquid

• reduced wear of the shaft seals

• reduced noise from operation. The disadvantages of enabling the "Low-flow stop function" may

be the following:

• The delivered pressure is not completely constant as it fluctuates between the start and stop pressures.

• The frequent starts/stops of the pump may in some applications cause acoustic noise.

The impact of the above disadvantages very much depends on the setting selected for the stop function.

The "High-comfort mode" setting minimizes pressure fluctuations and acoustic noise.

Select "Energy-optimal mode" if the main priority is to reduce the energy consumption as much as possible.

Possible settings of the stop function:

• "Energy-optimal mode" The pump automatically adjusts the parameters for the stop function so that the energy consumption during the start-stop operation period is minimized. In this case, the stop function uses the factory-set values of the minimum flow (Q fig. 67.

) and other internal parameters. See

min1

• "High-comfort mode": The pump automatically adjusts the parameters for the stop function so that the disturbances during the start-stop operation period are minimized. In this case, the stop function uses the factory-set values of the minimum flow (Q fig. 67.

) and other internal parameters. See

min2

• "User-defined mode" ("Customised operating mode"): The pump uses the parameters set for ∆H and minimum flow (Q

respectively for the stop function. See fig. 67.

English (US)

TM06 4267 1815

Fig. 67 Difference between start and stop pressures (∆H) and

minimum flow rate

In start-stop operation, the pressure varies between the start and stop pressures. See fig. 67.

In "User-defined mode" ("Customised operating mode"), ∆H has been factory-set to 10 % of the actual setpoint. ∆H can be set within the range from 5 to 30 % of actual setpoint.

The pump changes to start-stop operation if the flow becomes lower than the minimum flow.

The minimum flow is set in % of the nominal flow of the pump (see the pump nameplate).

In "User-defined mode" ("Customised operating mode"), the minimum flow has been factory-set to 10 % of nominal flow.

"Low-flow detection"

Low flow can be detected in two ways:

1. A built-in low-flow detection function which is active if none of the digital inputs are set for flow switch.

2. A flow switch connected to one of the digital inputs.

1. Low-flow detection function: The pump checks the flow regularly by reducing the speed for a short time. If there is no or only a small change in pressure, this means that there is low flow. The speed is increased until the stop pressure (actual setpoint + 0.5 x ΔH) is reached and the pump stops. When the pressure has fallen to the start pressure (actual setpoint - 0.5 x ΔH), the pump restarts.

– If the flow is higher than the set minimum flow, the pump

returns to continuous operation at constant pressure.

– If the flow is still lower than the set minimum flow (Q

min

), the pump continues in start-stop operation until the flow is higher than the set minimum flow (Q higher than the set minimum flow rate (Q

). When the flow is

min

), the pump

min

returns to continuous operation.

2. Flow switch: When the digital input is activated for more than 5 seconds because there is low flow, the speed is increased until the stop pressure (actual setpoint + 0.5 x ΔH) is reached, and the pump stops. When the pressure has fallen to start pressure, the pump restarts. If there is still no flow, the pump quickly reaches the stop pressure and stops. If there is flow, the pump continues operating according to the setpoint.

Operating conditions for the low-flow stop function

You can only use the stop function if the system incorporates a pressure sensor, a non-return valve and a diaphragm tank.

Always install the non-return valve before the pressure sensor. See figs 68 and 69.

"Set minimum flow"

Set the minimum flow (Q

) in this display. This setting

min

determines at which flow rate the system is to change from continuous operation at constant pressure to start-stop operation. The setting range is 5 to 30 % of rated flow.

Factory setting

See section 10. Technical data.

"Diaphragm tank volume"

The stop function requires a diaphragm tank of a certain minimum size. Set the size of the installed tank in this display.

In order to reduce the number of start-stops per hour or to reduce the ∆H, install a larger tank.

Install the tank immediately after the pump. The precharge pressure must be 0.7 x actual setpoint.

This function is typically used in pressure-boosting applications and ensures a smooth startup of systems with for instance empty pipes.

Startup takes place in two phases. See fig. 70.

1. Filling phase. The pipes are slowly filled with water. When the pressure sensor of the system detects that the pipes have been filled, phase two begins.

2. Pressure build-up phase. The system pressure is increased until the setpoint is reached. The pressure build-up takes place over a pressure build-up time. If the setpoint is not reached within a given time, a warning or an alarm can be given, and the pumps can be stopped at the same time.

The ramps determine how quickly the pump can accelerate and decelerate during start-stop or setpoint changes.

You can set the following:

• acceleration time, 0.1 to 300 seconds

• deceleration time, 0.1 to 300 seconds. The times apply to the acceleration from 0 rpm to maximum

(fixed) speed and the deceleration from maximum (fixed) speed to 0 rpm, respectively.

At short deceleration times, the deceleration of the pump may depend on load and inertia as there is no possibility of actively braking the pump.

If the power supply is switched off, the deceleration of the pump only depends on load and inertia.

7.44 "Multi-pump setup" ("Setup of multi-pump system")

"Multi-pump setup"

Pump variant

LCSE ● VLSE ●

The multipump function enables the control of two pumps connected in parallel without the use of external controllers. The pumps in a multipump system communicate with each other via the wireless GENIair connection or the wired GENI connection.

You can set a multipump system via the master pump, that is the first selected pump.

If two pumps in the system are configured with an outlet-pressure sensor, they can all function as master pumps and take over the master pump function if the other should fail. This provides additional redundancy in the multipump system.

The multipump functions are described in the following sections.

7.44.1 "Alternating operation"

Alternating operation functions as a duty/standby operating mode and is possible with two pumps of same size and type connected in parallel. The main purpose of the function is to ensure an even amount of running hours and to ensure that the standby pump starts if the duty pump stops due to an alarm.

Each pump requires a non-return valve in series with the pump. You can choose between two alternating operation modes:

• "Alternating operation, time"

Change from one pump to the other is based on time.

• "Alternating operation, energy"

Change from one pump to the other is based on energy consumption.

If the duty pump fails, the other pump starts.

7.44.2 "Backup operation"

Backup operation is possible with two pumps of same size and type connected in parallel. Each pump requires a non-return valve in series with the pump.

One pump is operating continuously. The backup pump is operated for a short time each day to prevent seizing up. If the duty pump stops due to a fault, the backup pump starts.

10.1 Operating conditions

10.1.1 Maximum number of starts and stops

The number of starts and stops via the power supply must not exceed four times per hour.

When switched on via the power supply, the pump starts after approximately 5 seconds.

If a higher number of starts and stops is desired, use the input for external start-stop when starting and stopping the pump.

When started via an external on/off switch, the pump starts immediately.

10.1.2 Ambient temperature

Ambient temperature during storage and transportation

Minimum: -22 °F (-30 °C) Maximum: 140 °F (60 °C).

Ambient temperature during operation

Minimum: -4 °F (-20 °C) Maximum: 122 °F (50 °C). The motor can operate with the rated power output (P2) at 122 °F

(50 °C), but continuous operation at higher temperatures reduces the expected product life. If the motor is to operate at ambient temperatures between 122 °F (50 °C) and 140 °F (60 °C), select an oversized motor. Contact Grundfos for further information.

10.1.3 Installation altitude

If the motor is installed above 6560 ft (2000 m), it does not comply with SELV/PELV classification.

Installation altitude is the height above sea level of the installation site.

Motors installed up to 3280 ft (1000 meters) above sea level can be loaded 100 %.

• Motors installed more than 3280 ft (1000 meters) above sea level must not be fully loaded due to the low density and consequent low cooling effect of the air. See fig. 72.

10.1.4 Humidity

Maximum humidity: 95 %. If the humidity is constantly high and above 85 %, open the drain

holes in the drive-end flange. See section Fig. 2 Examples of

covers (not supplied by Grundfos).

10.1.5 Motor cooling

To ensure cooling of motor and electronics, observe the following:

• Position the motor in such a way that adequate cooling is

ensured. See section 4.1.5 Ensuring motor cooling.

• The temperature of the cooling air must not exceed 122 °F (50 °C).

Keep cooling fins and fan blades clean.
