14.2 Error code table with hints on troubleshooting

Hints on the cause of the fault
Curvepoints of the ignition position are out-
side the end switch positions.
Curvepoints of «AUX1 / AUX2» curve are
outside the end switch positions.
When comparing the parameters in the in-
ternal data storage with those in the RZD20,
a difference was discovered.
This code also appears when the RZD20 is
replaced!
The signals between burner control or load
controller and RVW26... have an inadmissi-
ble signal combination.
Signal combinations inadmissible in terms of
time were detected on the signal lines to the
burner control, or an inadmissible signal
transition was detected.
Phase 1 in the program sequence of the
RVW26... was longer than 30 s.
Signal «LK-AUF» at terminal «Y10» of the
RVW26... was not present after 30 s.
RVW26... was longer than 150 s.
Signal «Fuel valve» at terminal «Q2» of the
RVW26... was not present after 150 s.
Signal statuses at terminals «F1» and «F2»
were not unambiguous during phases 1...7
and «Run». In phases 0, 8 or 9, «F1» and
«F2» are at AC 230 V.

Hints on troubleshooting
Reprogram the ignition position.
Check end switch position. If required, readjust
and measure the end switches.
Check curve.
If required, readjust and measure the end
switches.
Note compensation of hysteresis!
Check if the RZD20 is correctly plugged in.
Trigger copy process to / from the RZD20 to the
external / internal storage (programming level 7
«SavePar» / «GET_PAR»).
Check parameters and reset them if necessary.
Also refer to chapter «Replace data storage
module RZD20».
Check connecting wires between burner control
and RVW26... for false wiring, loose wires,
short-circuits or inadmissible contactor con-
tacts.
Measure voltages at «Y10» and «Y20».
If one of the voltages is inside the inadmissible
range (50...187 V), the outputs of the load con-
troller must be decoupled with relays.
Check wiring between burner control and
RVW26...
Check correct functioning of burner control.
Check compatibility of burner control and
RVW26...
Also refer to fault code «-08».
Check wiring between burner control and
RVW26..., especially the connecting lines to
terminals «Q3» and «Y10» of the RVW26...
Check correct functioning of the burner control.
Check wiring between burner control and
RVW26, especially the connecting line to termi-
nal «Q2» of the RVW26...
Check correct functioning of the burner control.
Check wiring at terminals «F1» and «F2».
Admissible statuses are described in section
«Selection of fuel».
