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.
