3x Flashing (Fault: Monitoring of Fan 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 operating voltage too low Measure the operating
voltage (DC) of TITA-
NUS
®
with a multimeter.
The measuring value
must lie between 14V and
30V.
Correct the supply voltage
2 Fan connection depolar-
ised The fan is at a stand-still.
Switch off the device.
On main board, clamp off
the connection cable of
fan.
Switch on power and let
the device run for a few
minutes.
If there is no collective
fault, the connection of
the fan is defective. Check ventilator connec-
tion to main board
(red - cl. 1; black - cl. 2)
3 Fan defective or blocked The diagnosis from step 2
points to depolarisation of
the ventilator. The con-
nection is correct.
Measure the ventilator
voltage (DC) of the con-
nected fan with a multime-
ter.
If the voltage lies outside
the limits shown below,
the fan is defective.
Adjusted ventilator volt-
age 6.9V: max. 7.6 V min.
6 V adjusted fan 9 V :
max. 10 V min. 7.8 V Because the fan cannot
be re-moved from the
housing, the complete unit
must be exchanged
4 Main board defective No cause could be estab-
lished in steps 1-4.
Switch off the device.
Replace the main board
with one of the same type.
Switch on power and let
the device run for a few
minutes.
If the main board was the
cause of the fault, this
should now be corrected. Replace defective main
board
5 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.
