• Prg (%) – calculated opening percentage of the channel.

• Max (%) – Maximum opening percentage of the channel.

The Prg. (%) and Min/Max (%) are calculated according to the fertilizer channel flow rate, allowed deviation and actual/measured water flow rate.

When EC/pH control is active the Open (%) will change according to the difference between the actual and the calculated EC/pH values.

If the Open (%) is close to the Min (%) or Max (%) it means that there is a big deviation between the fertilizer program settings to the actual injection ratio. The Open (%) cannot be higher than the Max(%) and cannot be lower than the Min (%), if it is identical to one of them than the NMC-64 controller will not be able to reach desired EC/pH values and the fertilizer program setting must be rechecked.

To enter any of the menus, press the corresponding numeric key or scroll to the desired item using the up/down arrow keys and press Enter; a new window will appear. The first menu under PROGRAM is IRRIGATION.

1.1 IRRIGATION

The Irrigation Program screen consists of all settings for automatic irrigation starts. It depends heavily on the Water Run Time and Dosing Program screens and therefore they must be filled before irrigation can actually take place.

The NMC-64 consists of 15 irrigation programs.

IRRIGATION PROGRAM

Program: 1 Priority 1 Const. 40%

Start Time Cycles Delay(Min.)

Valve #: Run Time #: Fert.Prog #:

Day: 04/06 Dose/Water

1 2 3 4 5 6 F W - F W F

• Program – Select a program by entering the program number and confirm by pressing Enter.

• Priority - Priority determines the order in which programs will take place. If start time is the same, higher priority programs come first. Higher priority programs do not stop currently operative programs.

If start time and priority are same, lower irrigation program number takes place first.

Priority ranges between 0 and 15, 15 being the highest.

• Const / Daily / Cond.:

• CONST. – Increase or decrease the amount of water for all valves included in

this program. 0% means the quantities will be as specified in the Water Run Time program, 100% will be twice the amount and –50% will be half the amount specified in the Water Run Time Program. To decrease enter the required percentage of change, press +/- key and than confirm with the Enter key. The percentage of change will be active until specified otherwise by the user.

Page 20

NMC-64 Irrigation

• DAILY – Increase or decrease the amount of water for all valves included in this program. 0% means the quantities will be as specified in the Water Run Time program, 100% will be twice the amount and –50% will be half the amount specified in the Water Run Time Program. To decrease enter the required percentage of change, press +/- key and than confirm with the Enter key. The percentage of change will be active only for the present day and will be automatically changed back to zero on End Day time.

CONST. % and DAILY % does not change Quantity / time of water before and water after settings nor dosing quantities.

• Cond. – Choose a Condition program to start / stop irrigations. Irrigations will be started and stopped according to the settings of the relevant Condition program (see CONDITION program for additional information).

The Condition program has the third priority after active irrigation and uncompleted irrigation (see paragraph

Priority specifications for additional information).

It is impossible to set same Condition program for two different programs.

For example: In the table above if the program was started manually or due to a Dry

Contact the irrigation in days 2 and 3 will take place as usual, meaning irrigation will be given as set in the associated Run Time Programs and fertilizer will be injected as set in the associated Fertilizer Programs.

• Start time (hh:mm) - Enter up to 6 start times (periods) per day for each program.

• Cycles - Set the number of irrigation cycles for each period. The first cycle starts at

the specified start time; subsequent cycles will start after the specified delay time.

• Delay - Time between start of a cycle until the beginning of the next cycle. For example if the set Run Time is 30 minutes and the Delay is 45 minutes the second cycle will start 15 minutes after the end of the first cycle.

• Valve # - The NMC-64 can operate valves in any required order; set the valve number, press enter, the following window will appear:

Select ‘–‘ (minus) and press ENTER to set the valve to operate alone or ‘+’ (plus) to operate together with the next valve. Several valves can be set to work together, as a group. Valves set, as a group will have the same Run Time program and the same Dosing Program. Each irrigation program can include a maximum of

Page 21

User & Installation Maunal Software

40 valves in any required order (all of them together, one after the other, a few groups, etc’).

• Run Time # – attach a Run Time Program to a valve or a group of valves. When setting valves to work individually, a Run Time Program should be set for each valve. When setting a few valves to work together (“+” mark between them) a Run Time Program should only be set for the first valve, the rest of the valves will follow this setting.

the quantity set in the Run Time Program will be the quantity given for all valves set to operate together, not per valve (for further specifications of the Run Time Program see 1.2 WATER RUN TIME).

• Dosing Program - attach a Dosing Program to a valve or a group of valves. When setting valves to work individually, a Dosing Program should be set for each valve. When setting a few valves to work together (“+” mark between them) a Dosing Program should only be set for the first valve, the rest of the valves will follow this setting.

• Day (xx/xx) – enables to define whether the program should irrigate, fertigate or be turned off on different days. The right setting enables to define the day’s cycle. The left setting enables to define the current day of the cycle.

Dose

WATER

NONE

Select one of Dose, Water or None and press ENTER. Dose means fertigation (water + dosing), Water means irrigation without dosing and None means the program is idle in that day.

Day: 04/06 1 2 3 4 5 6

Dose/Water D - W - D -

In the example above “Day: 04/06” the cycle days is 6, the current day is day 4. Day 2 and 5 are set to fertigate, day 3 is set to irrigate water only, and on days 2, 4 and 6 the program is idle.

When starting irrigation manually or due to Dry Contact the program will be activated regularly even if in Cyc. Day the Fert./Water definitions are set to WATER or NONE for the current day.

Page 22

NMC-64 Irrigation

Setting an irrigation that is longer than 24H:

An active irrigation will not change when the irrigation is longer than 24 hours there will be no changes in current sequence according to Cycle Days.

Example 1: If cycle days is 1 and the irrigation length is 30 hours, the irrigation will repeat itself every 30 hours, so that it will be continues irrigation.

Example 2: In order to perform an irrigation that is longer than 24 hours with stops in between, the day cycle should be more than 1. In the example above, if irrigation Run Time is set to 30 hours the program will operate as follows:

1. Fertigate for 30 hours

2. 1 day without irrigation.

3. Irrigate water only for 30 hours.

4. 1 day without irrigation.

5. Fertigate for 30 hours

6. 1 day without irrigation.

The NMC-64 includes 10 predefined dosing programs. Each program can operate according to one of four methods. Each channel can be set to give a different amount, overlapping between the various channels is possible.

Dosing programs can later be assigned to a valve or a group of valves in table

1.1

IRRIGATION

• Method – select one of four methods:

1. P.Qty (1/1000) - Proportional quantity. Each dosing channel can be set to to

give a different amount. The set amount is 1 part (Liter or Gallon) fertilizer/Acid per 1000 parts (m

/h or 1000 Gallons) of water.

• For example:

• Channel -1- is set to 5.0 (liters or gallons).

Page 24

NMC-64 Irrigation

• Set water quantity is 3.5 (m3/h or 1000 gallons).

The actual meaning of this setting is that 5.0 (liters or gallons) of fertilizer will be mixed with each cubic meter (1000 gallons respectively) of water passing through the system. The total quantity of fertilizer that will be given is 5.0 * 3.5 = 17.5 liters (Gallons).

2. P.Time (hh:mm) - Proportional time. Each dosing channel is independently given the time to fertilize. The NMC-64 divides this time equally within the given irrigation time (quantity) set in

• For example:

• Dosing channel -1- is set to 00:10, dosing channel -2- is set to 01:00.

• Set irrigation time is 03:00 hours.

The NMC-64 will proportionally divide the set fertigation time for each dosing channel across the set irrigation time (quantity). Dosing channel -1- will be on for a few pulses, their total time will be 10 min. Dosing channel -2- will be on for a few pulses (not necessarily the same amount), their total time will be 30 min.

1.2 WATER RUN TIME.

3. Time. (hh:mm) - Each dosing channel is given the time to fertilize. The dosing will be done in one bulk that will start after the water before time (quantity) set in

--:-- --:-- <NONE> One Shot <NONE>

• Start Dry Con. – Set the dry contact number for starting the irrigation.

• Trigger Type – Choose one of three trigger types:

1. One Shot – if the Start Dry Contact is closed for more than 20 seconds the associated irrigation program will be started. The contact must open and close to initiate another irrigation.

2. Multi shot – if the Start Dry Contact is closed for more than 20 seconds the associated irrigation program will be started. If the contact is still closed when the irrigation has finished another irrigation will be initiated.

Page 26

NMC-64 Irrigation

Notice that the Start Dry Contact doesn’t necessarily have to open and close in order to initiate another irrigation, is simply has to be closed when the irrigation has finished.

3. Only If On - the associated Irrigation program will be turned on providing the Start Dry Contact has been closed for more than 20 second and will remain on as long as the contact is closed.

• Stop Dry Con. – Set the dry contact number for stoping the irrigation. Since the Stop Dry Contact is “stronger” than the Start Dry Contact the associated irrigation program will not be started as long as the Stop Dry Contact is closed.

1.5 AGITATOR

1.7 FILTER FLUSHING

Enables to define the required process for filter flushing.

Notice that there are a few steps that should be defined prior to this screen:

• Table

 Stop irrigation during filter flushing - yes/no

 Stop fertilizing during filter flushing - yes/no

6 3 0

Time Between Flushing (hh:mm) - Time interval between two consecutive Flushing cycles. The time is only counted during irrigation.

Example: If time between flushing is set to 01:00 it means that after 1 hour of irrigation a flushing cycle will be activated.

• Flushing Time (mm:ss) – Flushing time of each Filter (output).

• Delay Between Filters (mm:ss) - The delay time between flushing of one filter to

the next. This time is usually used to enable buildup of pressure.

Page 28

NMC-64 Irrigation

• Delta Pressure – Define whether filter flushing can be operated due to Delta Pressure dry contact (Yes / No).

• Delay Delta Pressure (mm:ss) – define the time that the Delta Pressure dry contact input must be closed for before a filter flushing cycle will be initiated. This time is usually used to prevent unnecessary flushes from taking place.

• Delta Pressure Reiteration – number of consecutive filter flushing cycles due to Delta Pressure that can take place without any breaks before the NMC-64 will generate an alarm indicating that the Delta pressure sensor is defective. The NMC64 will than ignore the Delta pressure input and will continue flushing only according to the set Time between Flushing until the alarm is reset.

• Dwell Time Main Filter Valve (Sec) – define how much time before the filter flushing cycle is started the main filter valve must be on for. This output is typically used to control a pressure-sustaining valve or to start a booster pump.

1.8 COOLING

The cooling / humidification program is used to keep the greenhouse temperature below a set value and / or the humidity above a set value. Each program can be set to maintain temperature or humidity as its first priority.

There are 5 Cooling programs available with 2 periods in each program. The periods can be defined to overlap thus creating “dynamic” cooling or humidification.

Different temp. and humidity sensors can be connected to each program.

There are a few steps that should be defined prior to this screen:

If the temperature is below the highest value of the two periods humidification will not take place.

• From (hh:mm) – Set the start time of the Cooling / Humidification program.

• To (hh:mm) – Set the end time of the Cooling / Humidification program

The Cooling program will only be operative in the defined window of opportunity (between start “From” to end “To” times). Each Cooling / Humidification program can be operative on different hours.

• Above t

/ Below RH –

(when status is cooling) - Start cooling above this temperature.

Cooling will stop if the temperature drops below the internal dead-band of

. For example if set to 30o cooling will start when the temperature is

0.5 above 30

and will stop when it drops below 29.5o.

• Below RH (when status is humidification) - Start humidification below this humidity. Humidification will stop if the humidity goes above the internal deadband of 1%. For example if set to 80% humidification will start when the humidity is below 80% and will stop when it is above 81%.

• Below RH / Above t

–

• Below RH (when status is cooling) - Stop cooling above this humidity. Cooling will be resumed when the humidity drops below the internal deadband of 1%. For example if set to 80% cooling will stop when the humidity is above 80% and will be resumed when the humidity drops below 79%.

Page 31

• Above t

(when status is humidification) – Stop humidification when the temperature is below this temperature. Humidification will be resumed when the temperature goes above the internal dead-band of 0.5o. For example if set to 25 will be resumed when it goes above 25.5

humidification will stop when the temperature drops below 25o and

• On – define the On time of the Cooling valve.

• Off – define the Off time of the Cooling valve.

If On = 0, there is a constant rest.

If Off = 0, there is a constant work (In the time frame).

• Cool # - assign cooling valves to this program. The assigned cooling valves will be operated sequentially in groups. The size of the groups (maximum cooling parallel) is defined in screen 6.2 SYSTEM SETUP.

• Temp. Sens. – assign Up to 2 temperature sensors for this program.

• Hum. Sens. – assign up to one humidity sensor to this program.

If there is a malfunction in one of the temperature sensors, a message will be displayed and that sensor will be taken out of the average temperature calculation. If all the temperature sensors are out of order, the controller will operate according to the first active line.

If you would like to operate the program by time only, set as follows:

Set Status to cooling or humidification (not important). Set the Above t°. and Below RH to 0. Define required On and Off times and the program will work accordingly within the set time frame.

4.3 UNCOMPLETED PROGRAMS

The Uncompleted Programs table provides information of programs that could not be completed. It is important to understand the difference between this table and the Uncompleted Irrigations table; this table consists only of irrigation cycles that haven’t been started and could not be completed during current day. This can happen due to wrong setup of the system (more tasks than could be completed) or because the system was not active for a long period of time, for example due to power failure, and could not complete its tasks.

When a few pumps are connected to the irrigation process the NMC-64 automatically calculates which pump (or pumps) should be started. The calculation is done by summing up the nominal flow of all valves defined to work together and starting the minimal number of pumps required to supply the calculated flow rate. If a few pumps should be started the NMC-64 will start from the smallest to the largest and will turn them off from the largest to the smallest.

• Pump No. – pump number.

• Capacity – define pump capacity. This will be the maximum pump capacity, above

which the NMC-64 will turn on another pump (if available).

• Stability – define stability time. Stability time is the startup time required for current pump before next pump can be started up. Stability time is usually used to prevent voltage drop down and water hammer.

• Off Delay – define off delay. Off delay will be the delay time for current pump to stop after last pump has stopped. This delay is usually used to prevent water hammer.

• Irrig. (Yes/No) – define whether the pump is connected to the irrigation process.

• Cooling – define whether the pump is connected to the cooling process.

• Misting – define whether the pump is connected to the misting process.

Only one pump can be connected to the cooling process, and one pump to the misting process.

• React - Set whether the channel should be set to increase

• EC – the channel is used to increase measured EC.

• pH – the channel is used to decrease measured pH.

• Passive – the channel is idle to changes in measured EC/pH.

• HO – the channel is used to increase measured pH.

If EC & pH control is off, or channel is used for proportional injection only (for example in order to inject chemicals) set reaction to passive.

• High % - set a limiting injection percentage. This percentage will limit the deviation from set dosing recipe when NMC-64 is injecting more than defined in order to try and reach the target EC/pH values.

• Low % - set a limiting injection percentage. This percentage will limit the deviation from set dosing recipe when NMC-64 is injecting less than defined in order to try and reach the target EC/pH values.

If only EC/pH protection is required, with no correction, set fertilizer’s reaction to passive and EC/pH control (

LED’s indication

Several LED’s in the system can indicate the essence of a current problem.

CPU LED- In normal operation the LED will blink to indicate a watchdog update.

•

When the led isn’t blinking for a few seconds the system will reset. If the led hasn’t resumed blinking (LED OFF) than there is a major fault, probably in the CPU board.

•

OUTPUT LED- In normal operation the LED will blink to indicate a relays

update; every blink indicates that the main CPU updated the relays status and that communication between the cards is OK. In case of a malfunction, in communication or power, the led will stop blinking.

•

Communication LED’s- 2 communication LED’s indicate communication

between NMC-64 and PC / modem. When the LED’s aren’t blinking there is no communication between the NMC-64 and the PC / modem.

Problems and trouble shooting:

# Problem description Troubleshooting

Check led blinking. If the led on the output cards aren’t blinking, then the problem is probably that the I2C bus is pulled down by one of the cards.

Relays are not working, there are no sensor readings, and there is no communication with the hardware.

One of the output cards isn’t working at all.

(LED is switched off)

Alarm messages:

 Temp Sensor Shorted.

 Temp Sensor Opened.

 Temp Sensor User Err.

 Out Temp Sen. Shorted

 Out Temp Sen. Opened

 Out Temp Sen. Fail

Disconnect the output cards and digital input cards one by one and check whether the LED’s of the remaining cards starts blinking or the sensor’s readings are correct.

If you can’t find the faulty card it is probable that the CPU card is faulty, contact the Netafim dealer closest to you.

The reason for this problem is probably a short circuit in one of the relay coils. The short activates a thermal fuse on the power supply card.

Replace the relay card.

The reason for these problems could be that one of the sensors is shorted or disconnected.

Check the alarm messages to see sensor’s number and failure description; “Opened” or “Shorted”.

Connect Ohmmeter between the black and red wires of the temperature sensor and check if there is 30 kOhm. There are variations in the readings of the ohmmeter according to temperature. If the temperature is higher then 25°C the resistance will decrease and if the temperature is lower then 25°C the resistance will increase.

For example:

37.5 kOhm - in 20°C

24.1 kOhm - in 30°C

Cold Start procedure

Cold Start resets the NMC-64 to the original factory settings. This procedure should be performed after replacing a software version, when reinstalling the controller or when instructed by Netafim technician.

To perform a cold start:

1. Disconnect the NMC-64 power supply.

2. Turn power on, press and hold the delete key until cold start pop-up screen appears.

3. If you choose No, the NMC-64 will continue to its usual power up procedure; settings will remain untouched.

4. if you choose Yes NMC-64 will perform cold start procedure; controller will start with Ram and EPROM cleaning procedure. All controller settings will be erased and restored back to default factory settings. All history will be erased.

5. After cold start procedure has ended NMC-64 will return to the main screen; to use NMC-64 controller start installation from beginning.

It is recommended to save NMC-64 settings to Data-plug and / or PC before starting the cold start procedure. This will enable to restore previous settings and setup if required.

NMC-64 Irrigation

Short Circuit Control

General Description:

The NMC-64 uses a fuse to prevent damage due to high current short circuits; if a high current short circuit occurs the fuse either burns (in the plastic box version) or pops (in the metal box version).

In order to enable the NMC-64 to continue operating functioning devices the NMC-64 incorporates a short circuit detection mechanism. When a short circuit is detected the NMC-64 performs a test procedure to detect the faulty outputs, an alarm indicating that a short circuit was detected is given and an events indicating which outputs are faulty are registered.

Functionality:

When a short circuit is detected the system starts searching for the specific device which is causing it. The relay cards are shut down one after the other starting from card # 8 down to card # 1. When detecting a card that has a short circuit the relays are tested one after the other and those that have a short circuit are disabled.

Once a short circuit occurs an alarm is generated (one for all devices) and an event is given (

4.12 SYSTEM LOG) for each device that is detected with a short circuit.

Reset:

Outputs that are short-circuited (market “AL” in table 5.1 TEST > RELAYS ) are not turned on automatically and can not be manually turned on. After fixing the shortcircuit reset the alarm (table

3.1 ALARM RESET), the outputs are now functional.

Short-Circuit Threshold Level (A/D):

The NMC-64 CPU uses the short circuit detection mechanism to measure the 24VAC current load and translates it to an A/D reading of 0-999. The short-circuit threshold is user defined and depends on various parameters; 24VAC transformer size, number of devices to be operated simultaneously, power consumption per device, distance between controller to devices, cables dimension and resistance, etc’.

Setting Short-Circuit Threshold Level:

• Operate the maximum amount of devices to be used load possible).

simultaneously (maximum

• View measured A/D load on lower side of table

• Calculating desired threshold level:

• If the measured A/D value is up to 60 add 30.

5.1 RELAYS and write it down.

Page 83

User & Installation manual Appendix

• If the measured A/D value is 60 to 300 add about 50%.

• If the measured A/D value is above 300 add 150.

• Set the calculated value on table

Setting a higher value will result in a less sensitive system; system will detect short circuits in devices that are near the system but it will not be sensitive to devices that are further away.

The system will not always be able to detect short circuits in devices that are far away from the system (dependent on the cable length, resistance, etc’). Such short circuits generate a lower A/D reading, which might even be less then a reading of an operative device that is near the system.

To disable the short-circuit control set the value to 999.

Input/Output cards identification

3.3 ALARM DEFINITION “Short Output Level”.

• After Cold Start, the controller zeroes the cards data that is in the memory and researches the system.

• After identifying the cards, the controller saves the results.

• Once a minute, the controller runs a check on all the cards and makes sure that

the cards are connected and working properly.

• In case a card is missing or failed, the controller displays a message on the screen. If the card is found within a minute, the message disappears, if not, the message turns to an alarm.

• After RESET ALARM the controller turns off the alarm and refers to the missing card as not existing.

• In order to add a card you must turn off the power, place the card and turn the power back on. The controller searches for new cards in every power renewal and adds the new cards to the list.

• The new cards are now considered as cards that must always be found.

• Alarms for cards do not reset automatically. Reset the alarm manually from the

controller or the P.C.

Page 84

NMC-64 Irrigation

Analog Input Card:

• If only one card is present it will always be number 1, regardless of its position.

• When add a card to a system that already has one Analog input card, the new card

will be number 2 regardless of its position.

• Two cards installed in the system (After Cold Start), are numbered from right to left.

Digital Input Card:

• Cards numbering is according to the jumpers setting on the cards.

• If you add a new card with an identical number to one already in, the controller

sends a message of a numbering conflict and will disregard the new card. Turn off the power and change the new card’s number (Jumper).

• If after Cold Start there are 2 cards with identical numbers, the controller will recognize the right-sided one and will ignore the left one. Turn off the power and change the jumper position on the left-sided card.

Electrical grounding

Electrical equipment can be destroyed or slowly damaged by voltage spikes, lightning hits, etc’. Proper electrical grounding in combination with the NMC-64 internal protections is essential to protect the system, reduce the risk of damage and prolong its lifetime.

Correct selection and installation of equipment will protect your system and reduce the risk of human injury.

Proper grounding provides an easy path for electrical current to return to its source. A grounding system should tie all non-current carrying conductors to earth ground (0 volts). The grounding system should present a minimum resistance to current flow. Make sure all items used are in proper condition, for example, a corroded wire clamp attaching a ground wire to a ground rod might add 100 ohms or more resistance to a system.

Less than 5 ohm will be considered as a good ground.

Ground Rods

Ground rods are used to efficiently connect the system to earth where current may be dissipated in the soil.

• Material:

Ground rods should be copper clad or galvanized steel.

• Diameter:

Minimum 5/8”, preferably 3/4”. Generally the larger the rod diameter, the lower it’s resistance to current flow.

Page 87

User & Installation manual Appendix

• Length:

Minimum 2.5 meters (8 feet), preferably 3-meter (10-foot). A longer ground rod will reach a soil with higher moisture content. Moist soil carries current much better than drier soil.

• Single grounding:

It is important that there is only one grounding location where a rod or series of rods are connected to each other using a ground wire.

Independent ground rods will increase the risk of current, from a lightning strike for example, being dissipated through one rod and reentering the system through an adjacent rod.

• Location;

Close to the main circuit breaker panel and in moist soil. For example in an area that is usually wet from a drip or a low spot where water drains. Make sure the area is well protected from damage by lawnmowers, tractors, etc’.

Page 88

NMC-64 Irrigation

• Rod installation

Drive the rod into the earth until about 10 cm (4 inches) is left above grade. If it is impossible to drive the rod to the proper depth, it is acceptable to lay the rod horizontally, 80 cm (2.5 feet) below grade.

In case the rod is exposed to damage, for example by lawnmowers or tractors it can be installed in a hole, about 20 cm (8 inches) deep so that the rod is about 10 cm under grade and 10 cm above hole level.

The National Electric Code (NEC) mandates two ground rods unless you can show less than 10 ohms resistance with one rod.

Ground Wire

The ground wire is a large copper wire that connects the main circuit breaker panel to the ground rod.

• Material:

Ground rods should be copper clad or galvanized steel.

• Diameter:

Typically, 16 mm (6-gauge) copper wire is sufficient. If the wire run is greater than 20 feet, 20 mm (4-gauge) wire should be used.

• Length:

Minimum 2.5 meters (8 feet), preferably 3-meter (10-foot). A longer ground rod will reach a soil with higher moisture content. Moist soil carries current much better than drier soil.

The ground wire should be protected from damage by lawnmowers, tractors, etc’. It should be buried minimum 15 cm (6 inches) under grade for protection and enter the house as soon as possible. It is important that the wire not be cut; it should remain continuous.

Ground Clamps

Ground wires should not be merely wrapped around a ground rod. Ground clamps are used to attach a ground wire to a ground rod. The most common clamp is known as an acorn clamp.

Make sure the ground clamps you select are rated for outdoor use. Do not use pipe clamps rated for inside water lines or hose clamps to attach the ground wire.

Page 89

User & Installation manual Appendix

Ground connection

What Should Be Grounded?

Any equipment that is or could become energized, even accidentally, should be grounded. Current from lightning, strikes objects in a random fashion. Accounts of lightning strikes reveal scenarios most of us could not predict.

Electric circuits should be wired with a 3-wire conductor consisting of hot, neutral and grounding wires. The grounding wire should be attached cleanly and securely to devices or systems to be grounded. The other end of the grounding wire should be attached to the ground bus on the main panel.

Lightning Protection

1. Connect the shield to the ground at one end (controller side) of long shielded

wires such as for temperature and humidity sensors. When extending cables for temperature sensors and humidity sensors also connect the shield through the extension.

2. Run a heavy wire directly from the ground terminal to the ground rod, which must also be connected to the electrical service ground. The Ground should be less than 5 ohm resistance.

3. Do not use light wires for these ground connections. They must carry heavy lightning currents, sometimes exceeding thousands of amperes. The galvanized plate of the NMC-64 is the ground reference for it. You may connect the heavy ground wire using spare screws on it. Do not use the shielding of sensor and low voltage wiring as lightning grounds.

4. Ensure that all ground connections go to a single local point. When lightning strikes, grounds a foot or two apart will be at significantly different voltages. If you have several electronic boxes with individual grounds, connect all these together to a single point. This should continue to the ground rod or the electrical service. In particular, avoid grounding any controls remotely through shield wiring.

Page 90

NMC-64 Irrigation

ELECTRICAL CONNECTIONS

1. Install electronic equipment in a separate ventilated control room that is protected from extreme temperatures and dirty environments. Place the controls so that the operators can conveniently use the control and read indicators and displays.

2. Give your installation a professional appearance, with all wiring in conduit or neatly installed. Keep low voltage wires separate from high voltage wires.

3. Use shielded wiring for low-level signals. For buried wiring (building to building runs) use high grade jell filled cables that are impervious to moisture.

4. Seal cable entry points and control boxes to prevent contamination and corrosion. If you use silicon sealant with acetic acid cure, keep the control open and ventilated until cured. Otherwise, the acetic acid will attack the metal parts, including circuitry.

Page 91

User & Installation manual Appendix

SENSORS AND SHIELD WIRING

1. Do not use shields to create a path for lightning. For long shield wires, such as

building to building runs, connect the shield to ground at one end only, to

reduce the chance of conducting lightning from one building to another.

2. When splicing sensors to longer wires, ensure that the splice is waterproof. Use adhesive lined heat shrink (marine grade) to make waterproof connections.

3. Use a good compression connector for splicing. This is better than soldering. Do not simply twist wires together and then cover with electrical tape. This also includes wiring for the shield.

4. Keep sensor wiring separate from other power distribution and high voltage wiring. Ensure that lightning on other wiring will not transfer to the sensors.

5. Install outside temperature sensors so that the sun will not cause false readings, and so that exhaust air from the building will not affect the sensor.

Caution, risk of danger (read the manual)

Caution, risk of an electric shock.

Protective conductor terminal.

Earth (ground) terminal.

WARNING: Controller contains HIGH VOLTAGE, which can cause injury or death. Disconnect power supply before opening enclosure attempting connections. The connection of the mains power supply to the controller, pump starts and relay contacts that contain HIGH VOLTAGE should be performed by a licensed electrical contractor in accordance with all local, state and national elect

rical codes.

EC/pH correction adjustment

In order to set your system for optimal dosage the NMC-64 incorporates an advance PID algorithm that is suited specifically for that purpose.

Set your dosage as follows:

• Set a runtime program with sufficient time, 30 minutes or so (

TIME).

• Manually start a valve associated with the above set runtime program, no need to attach a dosing program (

To prevent damage during system tune up make sure you choose a valve that is not irrigating an active crop section.

• Manually open one of the fertilizer channels through table 5.1 TEST > RELAYS and measure the time until the NMC-64 recognizes the change (the EC should start going up). Make the same test for an acid channel.

• Manually stop the open valve.

• Choose the longest time of the two, add about 15% to it and set it as the control

cycle (table 7.7 DOSING CONFIGURATION).

• Put the coarse and fine-tuning to 1 (table 7.7 DOSING CONFIGURATION).

• Set a dosing program with reasonable settings (table

• Start the valve again, this time with the above set dosing program.

• While the system is fertigating and after verifying that there are no large

irregularities between set and actual flow start increasing the coarse tuning value until the system gets to an accuracy of about 0.3 to 0.4 to each direction. Than start increasing the fine-tuning until reaching the best possible accuracy.

2.3 START/STOP VALVE).

1.3 DOSING PROGRM).

1.2 WATER RUN

• After reaching a good accuracy stop the valve and start it again with fresh water only for a few minutes, until the system is flushed.

• Start the valve again, this time with the same dosing program you used before and check how long it takes the system to stabilize. If it takes it a long time try slightly increasing the coarse and fine-tuning.

Make sure you don’t set the coarse and fine tuning to strong as this will result in an unstable injection (overshoots and down shoots).
