Malfunction Cause Remedy
•
Incorrect mixture
•
Gas supply pipe mal-
function
•
The inlet pressure has
dropped below the min.
•
Clean filters in the inlet or
replace if necessary
(see Sec. 7.4)
•
Check inlet pressures
(see tech. data, Sec. 9)
•
Incorrect mixture
•
Incorrect setting of pro-
portion.
•
Solenoid valve leaks. A
very low flow is still
passing through the so-
lenoid valve, filling the
receiver up to control
pressure
•
Receiver pressure / max.
switching point setting to
high
•
Receiver pressure is
correctly set, but sole-
noid valve does not cut-
off the mixed gas flow at
max. receiver pressure
set-point
•
Incorrect pressure drop
between inlet-, control-,
max. receiver pressure
under flowing conditions
•
Alter setting due to require-
ment
•
Isolate mixed gas line down-
stream of the receiver and
observe receiver pressure
gauge. If receiver pressure
exceeds set max. value
(switching point) check cor-
rect setting of pressure switch
first
•
Solenoid valve faulty.

•
Follow manual, alter pressure
settings, if necessary
•
Solenoid valve opens/
closes in very high frequen-
cy (less than 2-3 sec.)
•
Size of mixed gas re-
ceiver does not fit with
mixer capacity
•
Restrictions between
mixer and receiver or in-
correct pipe-diameter
•
Mixed gas consumption
is slightly beneath mixed
gas max. capacity
•
Observe recommendation of
manual, install receiver of
suitable size
•
Check pipe and pipe-
diameter and install tube with
sufficient diameter
•
Increase inlet pressure/ con-
trol pressure to achieve high-
er capacity
•
No lights on alarm
module
•
No power supply
•
Alarm module faulty
•
Check connection to the
mains or connect to the
mains
