Burner Control CBR
Electrical Connections
Please follow all applicable safety regulations. Depicted configurations may differ from the actual scope of delivery, procedures however,
remain principally the same.
Tools:
•
screw driver
•
wrench
•
multi meter
Parts:
•
Burner controls CBR (ready for connecting and pre-
configured to customers specifications)
•
M8x1,25 screws or threaded studs (with washers and
nuts) 4x
Attention! Components under tension and high voltage!
Mount the burner control unit CBR in close proximity to the
burner. For mounting purposes the CBR has 4 molded nuts
(female threads) incorporated into the rear of the unit -
M8x1,25 (12mm deep).
Select a mounting location at which the ambient temperature
will not exceed 60°C .
From process control, connect the power supply 230V 50/60Hz
(optional 115V 50/60Hz) as well as the release signal „Safety
chain“, interlocked with the application safety chain, to the
control box. Make the connections according to the electrical
schematics supplied by WS. All connections must be fused
properly (depending on wire lengths, wire gauge, ambient
temperature, and power draw). The „safety chain“ signal
carries the load from the ignition transformer and the gas
valves connected to the burner. Signal exchange for burner
control can be hard wired (refer to electrical schematics) or it
can be achieved via Profibus communications (optional).
Connections from the CBR to the electrical components of the burner are pre-wired and pre-assembled
according to customer specifications. Please refer to the electrical schematics.
Please note, that NiCr-Ni dual thermocouples and the UV sensor must not be attached (changed)
with power ON. Danger of electrocution if phases of power supply are not connected correctly!
Prior to commissioning, all electrical connections and signal exchange must be verified by trained
electricians in accordance to local codes and regulations.
