4x Flashing (Fault: Monitoring of Air Pressure
Adjustment Voltage)
When operating two detector modules both LED’s flash. To eliminate a fault,
follow the steps below in sequence.
Step Possible Cause Diagnostics Measures
1 Setting of potentiometer
R3 for pressure-
dependent air flow ad-
justment is incorrect. Measure the voltage (DC)
on the measuring points
MP2 (+) and MP3 (-) with
a multimeter.
The standard pressure is
1.2 V; variations might
occur due to an adjust-
ment of the pressure-
dependent air flow.
If the measured voltage
lies outside the range of
0.5 V and 1.9 V, the
poten-tiometer R3 setting
is incorrect.
Notice: A fault occurs if
voltage is lower than 0.2
V or higher than 2.3 V.
Re-adjust the voltage
between measuring points
MP2 (+) and MP3 (-) with
the potentiometer.
For air pressure- inde-
pendent adjustment: 1.2 V
For air pressure-
dependent adjustment
according to air pressure
adjustment table in ap-
pendix.
2 Main board defective The voltage cannot be
adjusted in step 1.
Switch off the device.
On main board, pull the
connection cable off the
detector module.
Switch on power and let
the device run for a few
minutes.
The baseboard is defec-
tive if the voltage on MP2
and MP3 cannot be prop-
erly adjusted with the
potentiometer.
Notice: When operating
without detector module,
the diagnosis LED flashes
7x.
Replace main board
3 Detector module defec-
tive
Switch off the device.
Connect cable of the 1st
detector module with the
base board and detector
module.
If there is still a fault, the
detector module is defec-
tive.
Switch on power and let
the device run for a few
minutes.
When using two detector
modules, the process
must be repeated for the
second module. Replace detector module
4 If a fault cannot be eliminated after following the above steps, contact Wagner
Group GmbH and give a description of the fault together with the flash code
readings.
