The Series 653 High-Temperature Furnace is monitored and controlled by the
Model 409.83 Temperature Controller. The temperature controller contains a
control module for each hot zone in the furnace. Each control module accepts a
thermocouple input and outputs proportional power to the respective furnace
heating element. With certain controller cables, power to the elements is shut off
when there is a controller interlock.
