mode, press the START key to run pump, press the STOP key to stop pump.
NOTE: In manual state, the unit doesn’t receive signal from float switch
or pressure switch.
AUTO MODE:
Press the MODE key to switch to auto mode. Once the unit is in AUTO mode,
the pump will start or stop according to the signal from sensor, float switch or
pressure switch.
FAULTS AND PROTECTION:
During pump running, if dry run, overload, under voltage, over voltage etc.
failures happen, the control unit immediately stops the pump, displays it on the
LCD screen and automatically executes a check for restarting conditions after a
built-in time delay has elapsed. The control unit recovers automatically until all
the abnormal conditions have been cleared. However, the recovery time of the
control unit is different for different faults.
Details of recovery times for each fault have already been explained in this
manual. Recovery time for dry run and overload can be altered and set as per
needs. However, recovery times and values for under and over voltage are factory
set and can’t be altered.
NOTE: To reset immediately without waiting for recovery time, cut off
power supply and again switch on.
