Operation PS2/PSA2 1503L/2203L
Electrode
level sensor
operation
The following chart and diagram explain the actions of the electrode level sensor,
the timer, and the water level during normal operation..
Stage Electrode Level Sensor Pump Water Level
1 When the electrode level sensor contacts
water, the resulting electric current causes
the pump to operate. Operation
starts
(drainage) Falls
2 When the water level drops below the
electrode level sensor, a timer is activated.
The pump keeps operating. (No electric
current –>Timer activates.) Operation
remains
(drainage) Falls
3 The pump keeps operating for
approximately one minute. (The pump
resumes the operation if the electrode
level sensor contacts water again within
one minute.) Operation
remains
(drainage) Falls
4 The pump stops one minute later. (The
pump may not stop operating for a longer
period of time.) Operation
stops Rises
5 When the water level rises again and
contacts the electrode level sensor, the
pump starts operating again. Operation
starts again
(drainage) Falls
