Signification
At transgression of the adjusted time during
base load operation pumps do change.
'IS DEACTIVATED' effects that each
modification occurs only after reaching the
level 'BASE LOAD OFF'.
This function may be used to monitor the
flow rate of the pump.
Here unto a time above the normal pump-
down time has to be adjusted. A switch
occurs if the requested pump has not
pumped down under the switch-on point
within the adjusted time. After 3 consecutive
the error "Run-time Alarm" occurs.
The turn-on delay of the pump only functions
after a restart of the control system (e.g.
after a power failure). With "normal" switch
operation via the levels N1 and N2, this
setting is not relevant.
This function may be used to avoid the
simultaneous switch-on of several pumping
stations after a mains failure.
After having reached the turn-off level, the
pumps are still running for the adjusted
amount of time.
When both pumps are requested at the
same time, the second pump will be
switched on after the adjusted time, e.g. to
avoid mains overload.
If this function is deactivated, only one
pump works, e.g. to avoid overload of the
wastewater system.
If the adjusted value is reached, the
monitoring system of the pump motor current
effectuates the shutdown of the pump,
accompanied by a notice of malfunction.
The malfunction has to be acknowledged
manually by pressing the key
Attention : If the nominal current is
adjusted to 0 A no monitoring of the motor's
charging rate occurs !
Pump P1, P2 are briefly started if no request
occurs by the switch-on level within 24
hours.
If the ATEX mode is enabled, the 24h
starting is only taking place if the turn-off
level is exceeded.
