Fault lock-out

15 Fault lock-out
The control unit has identified errors on individual heater components
and faults during the starting procedure.
The heater is shut down (fault lock-out) if:
– No or incorrect start
– Temperature sensor defective
– Temperature limiter interrupt or short circuit
– Flow plug defective
– Blower speed too low or short circuit or break
– Error in the metering pump or overheating guard circuit (start phase
only)
– Undervoltage less than 10 V or overvoltage greater than 15 V and for
longer than 20 seconds (on 12 V heater)
– Undervoltage less than 20 V or overvoltage greater than 32 V and for
longer than 20 seconds (on 24 V heater)
– Control unit defective
– Overheating
The fuel supply is stopped if the heater overheats.
The heater continues to run in the same way as if it is switched off
manually.
After it stops the control unit will be set to fault lock-out. The overheating
is indicated by the indicator flashing 10 times.
Rectify the cause of the fault.
To reset the fault switch the heater off briefly (at least 2 seconds) and
then on again.

15.1. Error code output
NOTE:
The error code is output if the heater is fitted with a control element after
an error has occurred by the switch-on indicator/error code indicator
flashing. After 5 seconds of fast flashing, the error code will be output by
a sequence of long flash pulses, the number of flashes is shown in the
table below.
If the heater is fitted with a combination timer, an error message will
appear on the display of the timer after a fault occurs. If the control
element is used the error number is indicated by the indicator light
flashing:
F 00 Control unit error / incorrect parameter set /
warm start recognition
F 01 No start (after 2 attempts to start) / no flame formation
F 02 Flame failure (repeated >5)
F 03 Undervoltage or overvoltage
F 04 Premature flame recognition
F 06 Temperature sensor interrupt or
temperature sensor short-circuit
F 07 Metering pump interrupt or metering pump short circuit
F 08 Fan motor interrupt or fan motor short circuit or
blower motor incorrect speed
F 09 Glow plug interrupt or glow plug short circuit
F 10 Overheating
F 11 Temperature limiter interrupt or temperature limiter short circuit
F 12 Setpoint generator (interrupt / short circuit)
