Activity

Function
Lower water level until it is below the
switchpoint "Pump ON". Electrode rod 3
emerges
LED 3 illuminated
amber
Pump output contact 10/12 closed, 10/11 open.
Fill vessel until switchpoint "Pump OFF" is
exceeded. Electrode rod 3 enters the liquid
LED 3 not
illuminated
After the adjusted time delay (0-30s): Pump
output contact 10/12 open, 10/11 closed.
Relay 3 is de-energized too early or too late: Increase or decrease time delay with the aid of the potentiometer and
let electrode tip 3 emerge or enter the liquid again. Repeat the process until you have found the correct switchpoint
for the pump. If 30 sec. time delay is not enough for filling the boiler, select the operating mode "on-off pump
control".
ON/off pump control (fill control) = electrode rod 2 and 3
Set potentiometer for time delay to 0 sec.
Lower water level until it is below the
switchpoint "Pump ON". Electrode rods 2
and 3 exposed.
LEDs 2 and 3 are
illuminated
Pump output contact 10/12 closed, 10/11 open.
Fill vessel until switchpoint "Pump ON" is
exceeded. Electrode rod 2 enters the liquid
LED 2 not
illuminated
Fill vessel until switchpoint "Pump OFF" is
exceeded. Electrode rod 3 enters the liquid
LED 3 not
illuminated
Pump output contact 10/12 open, 10/11 closed.
Electrode rods 2 and 3 = on-off pump control (discharge control)
Set potentiometer for time delay to 0 sec.
Fill vessel until switchpoint "Pump ON"
is exceeded. Electrode rods 2 and 3
submerged.
LED 2 not illuminat-
ed, LED 3 illuminated Pump output contact 10/12 closed, 10/11 open.
Lower water level until it is below the
switchpoint "Pump ON". Electrode rod 3
emerges.
LED 3 not
illuminated
Lower water level until it is below the
switchpoint "Pump OFF". Electrode rod 2
emerges.
LED 2 illuminated
Pump output contact 10/12 open, 10/11 closed.
