Meaning for the LMV5x system
Fault with Base Unit (LMV5)
Wrong contact position of SR relay
Wrong contact position of ignition
Wrong contact position of BV relay
The diagnostic value is made up of the following faults or their
combinations (the individual diagnostic codes are added up in
hexadecimal format)
Contact position fault SV-oil
Contact position fault V1-oil
Contact position fault V2-oil
Contact position fault V3-oil
Contact position fault SV-gas
Contact position fault V1-gas
Contact position fault V2-gas (also caused by loose neutral)
Contact position fault V3-gas
Fault in connection with plausibility check.
For cause of fault, refer to diagnostic code
No fuel selection
No defined fuel train parameterized or undefined type of fuel
Variable "Train" not defined
Variable "Fuel" not defined
Operating mode with LC not defined
Prepurge time gas too short
Prepurge time oil too short
Safety time 1 gas too long
Safety time 1 oil too long
Ignition off time > TSA1 gas
Ignition off time > TSA1 oil

Corrective action
If fault occurs sporadically: Improve EMC
Check wiring on igniton transformer
1) Check to see if any source is feeding back voltage
onto the input. If so eliminate the voltage source.
2)Check for switches in the saftey loop that are opening
and closing again very quickly. This could be a pressure
switch or a low water cut-out that is on the edge of
opening and is "chattering". All outputs are powered
through the saftey loop, so the microprocessor that
monitors the outputs can detect this, resulting in a fault.
If fault occurs sporadically: Improve EMC
Select a fuel externally (by energizing or de-energizing
terminals) or selct a fuel through the AZL.
Select the proper fuel trains for gas and or oil (see
section 4)
Select a fuel externally (by energizing or de-energizing
terminals) or selct a fuel through the AZL.
The time defined by PrepurgeTmeGas(Oil) is less than
the time defined by parameter MinT_PrepurgeGas(Oil).
Change so that PrepurgeTmeGas(Oil) is longer than
MinT_PrepurgeGas(Oil). See section on settings.
The time defined by Max SafteyTGas(Oil) is less than
the time defined by parameter SafteyTmeGas(Oil).
Parameter Max SafteyTGas(Oil) can only be changed
by Siemens. Lengthen SafteyTmeGas(Oil).
