PROGRAM MENU
9.7 Selector
This screen enables the use of various fertilizer stock tanks. Every dosing program can be connected to one (or more)
selectors. Using the selector outputs you can choose which fertilizer stock will be connected to each dosing program.
Use the '+/-' keys to assign a selector to a dosing program.
9.8 Filter Flushing
Configuring the required process for filter flushing is allowed. Define the following before configuring this screen:
• Stop Irrigation During Filter Flushing
: Yes/No
• Stop Dosing During Filter Flushing: Yes/No
• Time Between Flushing (hh:mm): Time interval between two consecutive Flushing cycles. The time is only
counted during irrigation.
Example: If the time between flushing is set to 01:00 it means that a flushing cycle will be activated after 1
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.
