Check flame stability.
Check wiring.
Check flame sensor.
Check Parameter 774, 775 and 788.

Flame signal goes out immediately after ignition
H/Ü
If the flame extinguishes within three seconds after ignition, fault H010 is shown;
after that, fault H004 appears.
Check the flame stability.
Check the flame sensor setting.
Check the sensitivity of the sensor.
The deactivation time for the "Flame signal" digital input amounts to <200ms!
For this reason, a flame fault can also have another cause, e.g.:
- The solenoid fuel valve closes (EMC, low voltage)
- "Gas pressure < min" deactivation time <1s.

Internal fault: 5 sec. outside light monitoring period not kept
The fault can occur during an internal self-test.
Reset the fault. In the process, switch the mains voltage off and on again if neces-
sary.
Check all fuses in the device.
If the fault persists despite reset
exchange the device or respective card

relay module not connected or missing 24V supply for relay
Check the wiring between FMS and relay module 660R0016 and fuse F2 on the
FMS front panel.
FMS with relay module type 660 R 0016 V4.3 when the burner is at a standstill:
Check the wiring between FMS and 660 R 0016 V4.3.
If the wiring has been performed correctly:
Exchange relay module type 660 R 0016 V4.3.

main flame signals appears during ignition
If parameters 774 and 775 are set to value 3 or 4, only the ignition flame may be
present during ignition (up to the beginning of the second safety time). If the main
flame is detected in this time, fault S013 is displayed.
Check the flame sensor setting. The main flame sensor must detect only the main
flame and not the ignition flame.

The fault can occur during an internal self-test.
Reset the fault. In the process, switch the mains voltage off and on again if neces-
sary.
Check all fuses in the device.
If the fault persists despite reset
exchange the device or respective card.
