SYSTEM CONFIGURATION PROCEDURE
7.2 Pump Station Configuration
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.
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
schema).
• 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
schema).
• Station (Yes/No): Define whether the pump is part of the pump station.
The following is a startup and shutdown order schema according to the settings above and a calculated flow rate of 60
