Example: Use of IN 1
When IN 1 is activated the pump is
blocked and the signal "F1" is
displayed
ex. IN 1 could be connected to a
float
Example: Use of IN 2
When IN 2 is activated the regulating
pressure becomes "P1"
(switch over active setpoint:
SP or P1)
Example: Use of IN 3
When IN 3 is activated the electric
pump is blocked and the signal "F3"
is displayed
ex. IN 3 could be connected to a
safety pressure switch with
manual reset
