Device setting facilities:
The control system includes 4 DIP switches and 2 trimmers which can be used to set additional control
system functions.
DIP switch functions:
DIP 1: OFF The solenoid valve works without time limitations.
Solenoid valve time
limitation ON The solenoid valve on duration is limited to the time with which trimmer
1 is set (0.5….60 minutes). If the maximum operating level has not
been achieved within this period, the solenoid valve (K1) is switched off
and the collective error messaging system (K4) is activated if
necessary (see DIP 4).
DIP 2 OFF Dry run protection works without time limitation. When the water level
sinks below the "dry run protection" electrode, the pump (K3) is
switched off. It is only switched on again once the water level has
reached minimum operating level.
Dry run protection
time limitation
ON Dry run protection works with without time limitation. When the water
level sinks below the "dry run protection" electrode, the pump (K3) is
switched off. It is switched on again once the "dry run protection"
electrode has been immersed in water for 60 seconds, or if the water
level has reached the minimum operating level.
