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)
