Dosing liquid softener, valve -Y4
Burner programme selected and flow present:
–
Pulse time liquid softener is approx. 85ms, equals ap-
prox. 0.5 ml.
–
The waiting time between the pulses depends on the
position of the DIP switches and the set level:
NOTE
Dip switch 3 and 4 OFF only for HDS 9/50.
Flow switch (-S7) and pressure switch (-S11)
Upon the start, the electronics waits for approx. 1 minute
until the two signals are synchronous. This is necessary,
as the flow is already present shortly after the start, how-
ever, it takes a certain time until the pressure is built up, too
(e.g. due to air in the device). For this reason, the check of
the synchronicity of both switches takes place only after 1
minute after the start, then the two signals must be syn-
chronous within 4 seconds.
Flow switch closed and pressure switch closed within 4
seconds:
–
Diesel engine is running.
Flow switch open and pressure switch open within 4 seconds:
–
Diesel engine is not running.
Flow switch closed and pressure switch open within 4 seconds:
–
Diesel engine stops.
–
ERROR 5
is displayed.
Flow switch open and pressure switch closed within 4 sec-
onds:
–
Diesel engine stops.
–
ERROR 5
is displayed.
NOTE
In the frost protection mode only flow, but no pressure may
be applied! Should pressure be detected,
ERROR 5
oc-
curs.
Level switch detergent (-S12)
Initial start-up:
Plug the float switch into the control.
Switch on the device, wait for 20 seconds.

NOTE
For HDS 13/20 and HDS 17/20 only. As soon as the device
with the detergent is detected, the solenoid valve deter-
gent (-Y2) is activated when the gun is pressed. The quan-
tity of the detergent is controlled via the dosing valve.
Level switch float container (-S13)

–
Filling level OK.
Float contact open:
–
Diesel engine stops after 4 seconds.
–
ERROR 4
