Burner Control CBR
A FLOX
®
burner without the safety relevant temperature
acquisition via a NiCr-Ni dual thermocouple for release of
FLOX mode, must utilize the safety relevant inputs for
release of FLOX/Flame modes (XOR signal processing).
Input signals must are to be determined and activated by fail
safe temperature supervision. FLOX mode may only be
activated at the FLOX input terminal if the furnace temperature
is > 850°C via an active signal (230V AC L1 or optional 115V
AC L1). The input of the Flame release terminal must be
deactivated. A drop in temperature below the FLOX release
threshold, the FLOX release signal must be deactivated and the
Flame release signal must be activated. Switch over must occur
within one second, otherwise a fault shut-off will occur (F 57)
Prior to activating FLOX
®
mode, the FLOX/Flame switching logic, especially the electrical
connections, must be validated by trained personnel. Validation to be performed with the gas
supply turned off. Incorrect implementation can result in
EXPLOSION!
Electrical connects are made directly inside the CBR terminal
section (remove power and lock out). As an option, the CBR
can be supplied with an industrial connector for power supply
and input/output signals.
Profibus is optional and the interface is provided in form of a
Profibus connector (9 pin sub-D)
The CBR is pre-wired and tested at our facility. A project
specific electrical schematic is included inside every CBR.
Prior to commissioning, wire termination and controls must be verified and tested diligently by
trained professionals, in accordance to local regulations.
NOTE: all parameter settings are documented on the burner test data certificate. This certificate is
archived according to WS serial numbers. Please notify our electrical engineering department of any
changes made.
