TRD EN676
921 0 0 Relay driver self-test : output terminal 11 or 66 (ETAMATIC) faulty.
H/Ü Fault during an internal self-test.
Reset the fault; switch the mains voltage off and on again if necessary.
Check all fuses in the device.
If fault messages are constantly appearing one after the other

exchange the
device or respective card.
FMS with 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 660 R 0016 V4.3.
FMS with 660 R 0016 V4.3 at start of burner:
From the start of the burner, relay module type 660 R 0016 V4.3 checks the follow-
ing outputs:
- Ignition transformer (terminal 86)
- Ignition valves (terminal 85)
- Oil valves (terminal 84)
- Main Gas 1 (terminal 82)
- Main Gas 2 (terminal 83)
If faults H921 (in case of starting with gas as the fuel), H923, H924 (in case of start-
ing with O
2
as the fuel) occur by the time ignition is completed, the following faults
may be present:
- Lack of or too little firing rates at terminals 82 through 86
- Failure of fuses F1-F4 or F6
- Actual defect in one of the safety-related switching channels
For further troubleshooting, the diagnostic mode can be activated (see DLT6089/
DLT6065).
