7.1.6 Faults during ignition
Faults occurring during ignition may have 4 causes.
1. In case of additionally monitoring the pilot flame, the pilot flame may not suffi-
ciently be detected.
 Check the pilot flame for stable operation
 Check that the pilot flame is sufficiently visible within the viewing scope of the
compact flame detector, and change pilot burner adjustment if required.
 Realign the flame detector and check for cleanness of the viewing port
 Measure the flame radiation captured by the compact flame detector (section
7.1.4), and optimise alignment if required.
 Increase sensitivity if required.
2. Interference
Refer to section 7.1.5
3. If the flame has trouble to start-up, a timely recognition of the flame may be ham-
pered by an excessive start-up suppression.
4. Defect in the device
7.1.7 Faults during operation
Faults occurring during operation may have 3 causes.
1. The main flame may not sufficiently be detected.
- Check the main flame for stable operation - provide for visibility throughout the
operating range
- Check the compact flame detector for proper alignment and make sure that
the viewing port
- Measure the flame radiation detected by the compact flame detector (section
7.1.4), optimise alignment if required
- Increase the sensibility if required
2. Interference refer to section 7.1.5
3. Defect on the device
7.2 Troubleshooting
on apparently immaculate functioning according to the indicator elements
1. Check the output contact fuse and the contact
- Disconnect the flame detector from the supply voltage
- Check the normally-closed output contact at the 1st clamping point behind the
flame detector between the brown (BR) and the white (WH) connection wire
(avoid low-resistance continuity check – fuse 500 mA)
- Connect the flame detector to the supply voltage
- Check with simulated flame between the brown (BR) and the green (GN) con-
nection wire
