Switch/Pot.
Functions
Potentiometer for FLC-settings:
P1 for No. 1 pump
P2 for No. 2 pump
P3 for No. 4 pump
P4 for No. 3 pump
P8 to set pump stop time delay (0 – 2 min)
P9 to set pump stop time delay on low water cut-out (0 – 2 min)
Setting pressure setpoints (see pump duty chart, Fig. 5)

S 1
Effect reversal for input low-water cut-out:
S 1 open: Plant runs on closed contacts on terminals WM,
plant stops on open contacts on terminals WM
S 1 closed: Reverse action.
S 2
Test run:
S 2 open: Test run activated
S 2 closed: Test run deactivated
S 5
Sensor input:
S 5 open: Plant stops on opening of sensor contacts (without fault signal)
S 5 closed: Plant runs on opening of sensor contacts (oll pumps)
