7.1 Device Delay Configuration

The Device Delay Configuration screen enables defining the startup and shutdown order of the irrigation process.

• On (mm:ss): On is the definition of the startup order. The set times are taken from procedure startup. The
device with the shortest time will be started first and shifted to procedure startup. Therefore it is recommended
that the device that is to be started first be set as 00:00 (automatically changes to --:--).

• Off (mm:ss): Off is the definition of the shutdown order of the irrigation process. The set times are taken from
procedure shutdown. The device with the shortest time will be stopped first and shifted to procedure
shutdown. Therefore it is recommended that the device that is to be stopped first be set as 00:00

The NMC-Junior Pro can include up to six pumps. Each valve (irrigation, cooling or misting) can be connected to one
of the pumps or to the pump station. The pump station is a group of pumps (out of the six possible pumps) that will be
started in accordance with the required flow. The Pump Station configuration screen allows you to define which pumps
are part of the station, the capacity of the various pumps and their startup and shutdown delays.

Pump Station Configuration

Pump Station Configuration

The NMC-Junior Pro automatically calculates the expected flow and determines which pump (or pumps) should be
started (see Valve Configuration for additional information regarding flow calculation). The NMC-Junior Pro will start
the minimal number of pumps required to supply the calculated flow rate.

If several pumps should be started, the NMC-Junior Pro starts from the largest to the smallest and will turn them off
from the smallest to the largest.

• Pump No.: Pump number.

• Capacity: Define pump capacity in m3 or gallon. This will be the maximum pump capacity, above which the

NMC-Junior Pro will turn on another pump (if available).

• Stability (mm:ss): 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 (see

Pump Startup Order

• Off Delay (mm:ss): 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 (see Pump Shutdown Order

SYSTEM CONFIGURATION PROCEDURE

7.3 Valve Configuration

Valve configuration allows you to configure devices such as pumps, main valves and drainage measurement of
valves.

• Valve No.: Indication of the valve number.

• Pump: Define which pump or pump station should be started when irrigating this valve. When choosing

Station, the NMC-Junior Pro will choose which and how many pumps should be started to supply the required
(calculated) flow. See

• Pump Station Configuration on page 38 for more information).

• Main Valve: Define which main valve should be opened when starting each valve.

• Water Meter: Configure a water meter to each valve. This option is only possible when the flow calculation

(water meter type) is Standard.

Note: Make sure that you define an operative water meter. There is no protection against defining a water meter



that isn’t properly defined in the system.

Note that when operating using Water Source (refer to Water Meter, page 41) a valve is not configured to a specific
water meter. In this case, all water meters set in the system are relevant for each irrigation; their pulses are calculated
for the flow rate. Therefore the Water Meter column is irrelevant in the Valve Configuration table.

Note: Make sure that you define an operative water meter. There is no protection against defining a water meter



that isn’t properly defined in the system.

Note: When using more than one water meter only start two valves that are configured to the same water meter;



the NMC-Junior Pro uses only the water meter connected to the leading valve and does not sum the flow from
the rest of the water meters. Dosing in this manner can create unexpected alarms and malfunctions!

• Drain Meter: Define which drain meter this valve is connected to.

• Drain Type: Define drainage type:

Total: Drainage is collected from the complete valve area.



Sample: Drainage is collected from a representing part of the valve area.



Note that it is possible to set several valves to the same drain meter when working by 'Total'. The system does not
allow operating several valves on the same meter when operating by 'Sample'.

• Sample %: When using sample drainage measurement it is required to define the ratio of the sample area to
the complete valve area.

Page 39

NMC-Junior Pro Installation Manual

SYSTEM CONFIGURATION PROCEDURE

7.4 Valve Flow Rate

• Nominal: Define nominal valve flow rate (m3/h or gallon/min). The NMC-Junior Pro uses the set nominal flow
rate for calculating the ratio between valves when starting a few valves together, the boundaries for alarms,
the total flow rate for calculating how many pumps to start, etc. Therefore it is recommended to try and set the
nominal flow rate as close as possible to the actual flow rate.

• Minimum: Minimum valve flow rate, under which the system will generate a low flow alarm. When changing
the Nominal flow rate this setting is automatically set to 25% under the nominal flow, and can be manually
changed.

• Maximum: Maximum valve flow rate, above which the system will generate a high flow alarm. When changing
the nominal flow rate this setting is automatically set to 25% above the nominal flow, and can be manually
changed.

Note: When starting several valves simultaneously the system will sum their nominal, minimal and maximal flow



rates. An alarm will be generated only if the measured flow rate is lower than the total minimum, or higher than
the total maximum.

Note: When starting several valves simultaneously, the quantities between them will be divided based on the



ratio of their nominal flow.

• Ratio: Set volume per pulse of each water meter or auxiliary meter.

• Type: Define type of flow calculation:

Standard: In this function valves which are operated in a group should be connected to the same water



meter.

Note: If a few valves configured to different water meters will be started simultaneously, the NMC-Junior Pro



uses the flow measured by the water meter connected to the leading valve.

Water source: The NMC-Junior Pro will sum or deduct flow measured simultaneously from a few water



meters. When choosing this function an additional column called ”SUM” will appear, this column
enables to define which water meters should be summed and which deducted from the total measured
flow.

Note: Flow calculation type is a general definition for all water meters, therefore when changing type of water



meter for one of the water meters the type will be changed for all water meters.

Note: When setting flow calculation (water meter type) to Water source it is not possible to configure valves to



water meters.

• Sum: Define whether flow measured by each water meter should be added to the total measured flow or
deducted:

“+” Flow measured by this water meter will be added to the total measured flow.



“–” Flow measured by this water meter will be deducted from the total measured flow.



Note: Since flow cannot be negative, if the controller measures negative flow it will show zero.



Note: If all valves are set to "–" the system ignores the measured flow and will use the nominal flow (based on



the nominal flow).

SYSTEM CONFIGURATION PROCEDURE

Note: It is very important to choose the correct flow meter for the application. Choosing a wrong flow meter might



result in measurement errors or an inaccurate control. For instructions regarding how to choose the correct water
meter see NMC-Junior Pro Irrigation > General > Flow meter determination.

7.6 Dosing Channel Configuration

• Pump: Select the type of dosing pump:

Venturi: The dosing unit consists of Venturi driven injectors. The dosing booster will be turned on when



fertigation is active.

Hydraulic: The dosing unit consists of hydraulic fertilizer pumps. The dosing booster is not needed and



will not be turned on when Fertigation is active. When working with hydraulic pump, the method can
only be Liter/Pulse and EC & pH control is not possible.

Electric: The dosing unit consists of electrical fertilizer pumps. The dosing booster is not needed and



will not be turned on when Fertigation is active.

• Method: Select the operating method:

Liter/Pulse: Define whether a dosing meter is connected to this channel and used for control purposes.



Set the volume per pulse on the Ratio column.

Time (cc/sec): Define whether the calculated flow rate of the dosing channel is in CC (gallons) of



fertilizer per second.

Time (Liter/min): Define whether the calculated flow rate of the dosing channel is in liters (gallons) per



minute.

Time (Liter/Hour): Define whether the calculated flow rate of the dosing channel is in liters (gallons) per



Hour.

• Ratio

Method is Time: Define calculated flow rate, this will be the flow rate of the channel when completely



open.

Method is Liter/Pulse: Define the volume per pulse.



• React: Set the required use of the channel:

EC: The channel is used to increase measured EC, meaning it will be opened more when the measured



EC is lower than the set EC.

pH: The channel is used to decrease measured pH, meaning it will be opened more when the



measured pH is higher than the set pH.

Passive: The channel does not respond to changes in measured EC/pH, meaning it will be opened as



set in the dosing program regardless of the EC/pH values.

Alkali: The channel is used to increase measured pH, meaning it will be opened more when the



measured pH is lower than the set pH.

Note: If EC/pH control is off, or the channel is used for proportional injection only (for example in order to inject



chemicals) set reaction to passive.

• High %: set an injection percentage limit. This percentage will limit the deviation from set dosing recipe when
NMC-Junior Pro is injecting more than specified in order to try and reach the target EC/pH values.

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

Page 42

NMC-Junior Pro Installation Manual

SYSTEM CONFIGURATION PROCEDURE

• V/P(L/G): This parameter is disabled when operating by Liter/Pulse. Define the volume per pulse of the
dosing meter (liters or gallons). Only required when using a dosing meter for measurement and alarm
purposes. When using a dosing meter for control purposes the volume per pulse of the dosing meter should
be defined on the Ratio column. The letter between the brackets indicates whether the volume units are in
Liter or Gallon.

7.7 Dosing Configuration

• EC Control: Define whether EC control should be operative.

• pH Control: Define whether pH control should be operative.

• EC Alarms: Define whether EC related alarms are operative. When EC control is set to ‘Yes’, EC Alarms are

automatically set to ‘Yes’ and cannot be changed.

• pH Alarms: Define whether pH related alarms are operative. When pH control is set to ‘Yes’ pH Alarms are
automatically set to ‘Yes’ and cannot be changed.

• Minimum On Time (sec): Define the minimum time the dosing regulator can be open. This feature is used to
protect the regulator from being excessively turned on and off. The minimum allowed on time is 0.4 seconds.

• Minimum Off Time: Define the minimum time the dosing regulator can be off. This feature is used to protect
the regulator from being excessively turned on and off. The minimum off time allowed is 0.4 seconds.

• EC Coarse Tuning (0-10): EC Coarse Tuning is used to adjust the speed and strength of the EC control. A
higher value will result in faster correction but might lead to over shooting (see Appendix 1 – General > EC/pH
correction adjustment for further information).

• EC Fine Tuning (0-10): EC Fine Tuning is used to fine tune the EC control shooting (see NMC-Junior Pro
Irrigation > Part 2 > General > EC/pH correction adjustment for further information).

• pH Coarse Tuning (0-10): pH Coarse Tuning is used to adjust the speed and strength of pH control. A higher
value will result in faster correction but might lead to over shooting (see NMC-Junior Pro Irrigation > Part 2 >
General > EC/pH correction adjustment for further information).

• pH Fine Tuning (0-10): pH Fine Tuning is used to fine tune pH control shooting (see NMC-Junior Pro
Irrigation > Part 2 > General > EC/pH correction adjustment for further information).

• Control Cycle (sec): Define the control cycle for EC/pH control. This should be the time it takes the system
since it injected fertilizer/acid until the change in recognized by the system.

• EC/pH Averaging (0-Low, 20-High): Averaging factor for EC/pH measurement. EC/pH averaging should be
used to enable correction when injection is not homogenous.

• Dosing Booster Off Delay (mm:ss): Define the time that the dosing booster should be left on after dosing
has ended. This time is usually used to circulate the acid and nutrients in order to prevent high concentrations
in the area of the venturies and dosing booster when the system is idle.

• Dosing by QTY. Method:

Bulk: All channels set to QTY (quantity) dosing method will inject the set quantity in one bulk, starting



after water before quantity/time has elapsed.

Spread Out: The set dosing quantity of all channels set to QTY (quantity) dosing method will be spread



throughout the irrigation.

The figure above shows “Day: 04/06”, meaning the number of the days in the cycle is 6, and the current day is day 4.
Day 1 and 5 are set to dose, day 3 is set to irrigate water only, and on days 2, 4 and 6 the program is idle.

9.1.1 Setting Irrigation that is Longer than 24 Hours

If a cycle day is 1 and the irrigation length is over 24 hours, the irrigation will repeat itself continuously, which means
continuous irrigation.

Note: Dosing operates according to ('D-W') for the same day and not according to the setting when the irrigation



has started. If irrigation starts at 18:00 and on this day dosing is set ('D'), the irrigation crosses midnight to a day
where no dosing is set ('W'), dosing stops at midnight!

9.2 Influence Program

NMC Irrigation Junior Pro enables adjusting irrigation settings according the following factors (labeled “Influences” on
the screen):

• Solar radiation

• Amount of drainage

• Amount of fertilizer present in the drainage

• VPD

• Temperature

These Influences can adjust the following irrigation settings:

• EC

• Radiation Sum (RadS)

• Minimum Rest Time (MinT)

For example, a grower may want to increase the EC based on the Solar Radiation. Alternatively, he may want to
decrease the MinT based on the drainage.

• Using the Influences

• Setting the Influences

9.2.1 Using the Influences

• Set an Influence to increase or decrease the setting.

• Changes to the setting are in percentages (for example, a 10% increase in the EC level).

• Several Influences adjust the EC setting. The final adjustment amount is based on the sum total of the

different Influences.

• You enter up to three points for each Influence setting. Irrigation Junior Pro automatically calculates the curve
based on these points.

• You can program up to 15 different programs (corresponding to the 15 irrigation programs)

• After configuring an Influence, you must enable it (under ACTIVE/SOURCE).

9.2.2 Setting the Influences

1. Go to Install > Device Layout.

2. Define relays as dosing channels, as required.

3. Go to Program > Irrigation.

This setting actually means 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 given the time to fertilize independently. The NMC­Junior Pro divides this time equally within the given irrigation time (quantity) set in 1.2 WATER RUN TIME

.

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-Junior Pro will proportionally divide the set fertigation time for each dosing channel across the set

• Trigger Type: Choose one of three trigger types:

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 irrigation.

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, irrigation will be
initiated.

Note: Notice that the Start Dry Contact does not necessarily have to open and close in order to initiate irrigation.

hour of irrigation (regardless of DP status).
If set to zero (--:--), flushing will only take place if triggered by a DP.

• 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 allow pressure buildup.

• Delta Pressure (Digital): Define whether filter flushing can be triggered due to digital Delta Pressure (Yes /
No).

• Delay Delta Pressure (mm:ss): Define the time that the Delta Pressure (digital or value) must be active
before a filter flushing cycle will be triggered. This time is usually used to prevent unnecessary flushes from
taking place.

• Delta Pressure Reiteration: Number of consecutive filter flushing cycles triggered by the Delta Pressure that
can take place without any breaks, before the NMC-Junior Pro will generate an alarm indicating that the Delta
pressure sensor is defective. The NMC-Junior Pro will than ignore the Delta Pressure and will continue
flushing according to the set Time Between Flushing only, until the alarm is reset.

The Cooling/Humidification program is used to keep the 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.

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

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

The Status can be defined as Cooling or Humidification, the aim of the status field is to help the user to understand the
process that should take place by placing the related set point first (i.e. above t° when the status is cooling OR bellow
RH when the status is Humidification)

Note: There are a few steps that should be defined prior to this screen: see Cooling Configuration.

COOLING/HUMIDIFICATION PROGRAM

• Program: Choose the required program 1 to 8, press ENTER to confirm.

• Status: define whether the program’s first priority is maintaining temperature or humidity.

• Cooling: the program’s priority is temperature. If the two periods are overlapping and there are different

settings in each period, dynamic cooling will take place.

Example:

• Settings:

Period 1 is set between 08:00 to 16:00. The cooling process should work above temp. of 30oC and



Below RH of 80%.

Period 2 is set between 08:00 to 16:00. The cooling process should work above temp. of 40oC and



Below RH of 80%

On time is fixed to 30 sec in both periods.



Off time is 3:00 minutes which relates to the lowest temperature setting (30°C)



Off time is 1:00 minute which relates to the highest temperature setting (40°C)

opened.

• Off (hh:mm:ss): Define the Off time of the Cooling valve. If Off time is set to zero the Cooling valve will be
constantly On.

• Cool #: Assign cooling valves to this program. The assigned cooling valves will be operated sequentially in
groups. The number of groups (different cooling programs) which can be operated simultaneously (maximum
cooling parallel) is defined in screen 6.2 SYSTEM SETUP

• Temp. Sens.: Assign Up to two temperature sensors for this program.

• Hum. Sens.: Assign up to two 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 the required On
and Off times and the program will work accordingly within the set time frame.

9.10 Misting

The misting program is a time scheduler used to open/close a misting valve or any other device that is operated
sequentially. Up to 40 misting programs can be preset.

Note that there are a few steps that should be defined prior to this screen, see the Misting Configuration Table on
page 45.

• Mist No.: Assign a mist valve to the program. It is possible to associate the same misting valve to several
programs.

• Start (hh:mm): Set the start time of the Misting program. If start time is set to 00:00, it will automatically be
changed to --:--, meaning the program is not operational.

• End (hh:mm): Set the end time of the Misting program. The Misting program will only be operational in the
defined time window (between Start to End times). Each Misting program can be operational on different
hours.

• On: Define the On time of the misting valve. If On time is set to zero the MISTING valve will not be opened.

• Off: Define the Off time of the MISTING valve. If Off time is set to zero the MISTING valve will be constantly

On.

The table is sorted according to mist number as the first priority, and start time as the second priority. The Mist No. will
always appear in groups in an increasing order so that the orientation is quick and easy.

Each mist group has an inside start time sorting, so that a later start is moved to the end of the group. If you delete a
row (by zeroing the Mist .No.) it will be moved to the end of the table and the rest of the rows will move one step up.
Pressing the menu key does this sorting.

Note: When misting is on all related devices (e.g. misting valve, main valve and pump) are operational. When



misting is off, only the pump continues to operate

COMMUNICATION

• Controller Number: Select the controller number for communication. The controller number in the controller
and in the PC should match in order for the communication to work. Each controller in the network must have
a unique number.

WATER SOURCE

• Flow Rate – Start From: Select whether the flow rate calculation in an irrigation will begin either with the
value Zero (which means that the flow rate will increase according to pulses received), or a Nominal value
calculated using all the active valves in the irrigation. The calculation method is important primarily for dosing
and EC/pH control. When using a controller which operates with relatively slow pulses, it is recommended to
choose the Nominal flow rate option due to inaccurate flow calculation in the first stage of the irrigation. When
operating with slow pulses and starting with a Zero value, it will take a long time for the controller to reach its'
actual flow rate value. When operating by fast pulses, choose either Zero or Nominal.

• Calculated Flow Delay: This parameter is relevant only when Nominal is being selected in the previous
parameter. This parameter defines the time the controller uses its' nominal flow rate value before switching to
the calculated one. In this period LOW FLOW and HIGH FLOW alarms will not be detected.

To enable this parameter, set the Water Meter to Water Source. Refer to Water Meter, page 41.
