Please follow all applicable safety regulations. Depicted configurations may differ from the actual scope of delivery, procedures however,
remain principally the same.
Attention: Danger of electrocution!
Remove power (lockout and tag out) prior to working on electrical components.
Fault trouble shooting by authorized trained professionals! Repair attempts on the CBR will void
the warranty!
Improper attempts at repairs and incorrect electrical connections, for example providing power to
output terminals can cause gas valves to pen and destroy the CBR – fail safe operation can no
longer be guaranteed!
Attention: Danger to life and limb by electrical shock!
Remove power from any electrical components prior to commencing work!
Only trained, authorized professionals are permitted to perform electrical work. Repairs of the CBR are not
permitted – warranty voided if attempted. Incorrect repairs or electrical connections e.g. powering
outputs can open gas valves and destroy the CBR – fail safe functionality of the unit is no longer
guaranteed.
Most faults can be reset, thus restarting the burner, by pressing the local reset button

for a minimum of
¼ second, or by activating the remote reset signal.
In case of reoccurring fault, avoid multiple or continuous reset attempts and determine the root, cause of
the fault by trouble shooting the burner.
Reset attempts are limited to five (5) per 15 minute interval. (refer to fault
F 04
)
Each reset will initiate a restart, indicated by a flashing:
8 88
This is always followed by several seconds of air purge and burner a relight attempt (look at parameter).
For some faults the CBR can be configured so that they do not cause a shut-off of the burner. The fault is
then indicated on the CBR display.
Please contact the WS service department if a fault persists and can not be reset.
Power down the burner control box and close the manual gas shut-off valve. Isolate the burner from the
exhaust system (i.e. Shut-off valve or blind flange). The faulting burner should be locked out and tagged
out to prevent unintended activation.
