252 Actual signals and parameters
STOP
Detection of very low inlet pressure stops the drive. The
drive starts again if the pressure exceeds the supervision
level.
1
FAULT
Detection of very low inlet pressure trips the drive on a fault. 2

4406 DI STATUS
INLET
Selects the digital input for connection of a pressure switch
at the pump/fan inlet. The “normal” state is 1 (active). If the
selected input switches to 0 (inactive), the action defined by
is executed after the
expires.
