7.2 PUMP CONFIGURATION

Pump configuration screen enables to define the capacity of the various pumps, their
startup and shutdown delays, and configure them to the processes.
Pump Capacity
No. m3/h
1 10.000
2 20.000
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.
