CAUTION
DO NOT USE A BURNER CONTROL MOTOR WHICH
INCORPORATES A 24-VOLT TRANSFORMER WITH
THIS PANEL.
If you are retrofitting this panel to an existing system, it
may be necessary to remove the cover(s) from your
existing control motor to determine whether or not It
incorporates the transformer If it does, physically remove
the transformer or, at a minimum, cut/remove all leads
originating from the transformer and tape them to prevent
accidental shorting or grounding
IF
A
CONTROL
MOTOR
WITH
A
24-VOLT
TRANSFORMER IS CONNECTED TO THIS PANEL,
EXTENSIVE DAMAGE TO THE MODEL UDC3000
MICROPROCESSOR TEMPERATURE CONTROLLER
WILL RESULT.
The BCS-3000 is compatible with
Barber-Colman
medium and high torque motors. Other actuators may
require revised electrical hookup
A. GENERAL INFORMATION
The BCS-3000 tabletop control panel provides burner management and temperature control of a single pilot-ignited burner
firing on either gas or oil. The spark ignited, gas fired pilot Is interrupted after the main burner flame has been established.
Two Honeywell UDC3000 series microprocessor based controllers are provided for temperature control. The temperature
controllers are electrically linked to the burner control motor to automatically adjust the burner firing rate to keep the
process temperature near setpoint.
The STACK TEMPERATURE controller thermocouple senses the temperature of the exhaust gases while the MATERIAL
TEMPERATURE controller thermocouple Is positioned to read the temperature of the material as it exits the dryer. Both
instruments generate a motor positioning output based on the difference between the controller setpoint and process
temperature input. The CONTROL MODE selector switch enables the Operator to assign control of the burner to either
controller. An alarm contact in the STACK TEMPERATURE controller is used to shut down the system if the preset high
temperature limit is exceeded.
