※
※
When the water level rises and the water
surface comes in contact for more than one (1)
second
with the electrodes, the pump will
restart.
The pump will stop 1 minute later.
The pump will also stop after a continuous
dry run, in some cases.
If the water surface comes in contact for more than
one (1) second with the electrodes within 1 minute,
the pump will operate continuously even though the
timer has tripped.
As the water level drops and the water
surface recedes from the electrodes, the
timer trips to drain water.
The electrodes of the level relay unit are
submerged, causing the current to operate
the pump.
