81.01
Inlet prot ctrl
Enables the primary supervision of pump inlet pressure and
selects the action taken when low inlet pressure is detected.
The selected action is taken only after the measured
pressure has remained below the pressure limit (
) for longer than the value of parameter
The pressure can be measured using an analog pressure
sensor or a pressure switch.
The input for an analog sensor is defined by parameter
. With an analog sensor, a separate
action for “very low inlet pressure” can be defined using
parameter
The input for a pressure switch is defined by parameter
.
Not used
Primary inlet pressure supervision not used.
0
Alarm
Detection of low inlet pressure produces an alarm after the
delay defined by parameter
expires.
1
Fault
Detection of low inlet pressure trips the drive after the delay
defined by parameter
expires.
2
No.
