Meaning of the REC 27.100A2 system
Relay supervision error
The safety relay contacts have joined together or the safety
relay has been powered by an external power supply
Relay supervision error
The relay does not start up
Relay internal checking error
Relay internal checking error
Relay internal checking error
Contact sampling internal error
Blocked upon irregularity
Contact request internal error
Voltage monitoring test internal error
Low level of power supply
Reset power supply voltage
Mains voltage supervision internal error
flame control meter internal error
Life cycle of the flame control in the critical interval
(250,000 Start ups)
Life cycle of the flame control exceeded
Interruption of fuel limiting meter input
EEPROM access internal error
57
Recommended measures
Check the contacts:
1. flame control connected to the power supply: the fan output
must be without voltage.
2. Disconnect the power supply. Disconnect the fan. The
resistive connection between the fan output and the neutral wire
is not allowed.
If one of the 2 tests fails, replace the flame control because the
contacts are definitively joined together and it is no longer
possible to guarantee safety.
Carry out a reset; if the error arises repeatedly, replace the unit
Carry out a reset; if the error arises repeatedly, replace the
flame control
Carry out a reset; if the error arises repeatedly, replace the
flame control
Software version V03.10: If error C:99 D:3 occurs during the
standardisation of the VSD, temporarily deactivate the Alarm
function at the start of the pre-purging phase (parameter 210 =
0) or interrupt the signal controller-ON
Carry out a reset; if the error arises repeatedly, replace the
flame control
Can be caused by capacitive loads or presence of DC voltage
on the main power supply of the flame control. The diagnostic
code indicates the input in which the problem arose
Carry out a reset; if the error arises repeatedly, replace the
flame control
Carry out a reset; if the error arises repeatedly, replace the
flame control
Insufficient mains voltage.
Conversion of the diagnostic code
Voltage value (230 V AC : 1.683)
Error code for the carrying out of a reset in the event of power
supply restoration (absence of error)
Carry out a reset; if the error arises repeatedly, replace the
flame control
The envisaged life cycle of the flame control has been
exceeded. Replace it.
The switch-off threshold has been reached.
Too many disturbance impulses on the input of the fuel meter.
Improve the electromagnetic compatibility.
Carry out a reset, repeat and check the last setting of the
parameters. Restore the group of parameters: if the error arises
repeatedly, replace the flame control.
