PUMP TECHNICAL DATA
10. Level detector connection
1. Minimum level detector (low level S1):
Level detector must be connected to protect the water pump
working. Water level in basin is detected by this level detector (J17
sensor indicates minimum water level NO, take a look on CCB2.0
manual).
2. Maximum level detector (high level S2):
The maximum level is used as a security system in a float valve
regulation water feed possible failure event. It must not be used to
regulate the fresh water inlet.
I
n case the equipment has a filling
solenoid valve, connect it to this level so that it is cut for safety
(J16 sensor indicates maximum water level NC, take a look on
CCB2.0 manual).
Remark:
