Series 653 High-Temperature Furnace Cable Connections
The thermocouple cables must be connected between the Series 653 High-
Temperature Furnace and the temperature controller.
Procedure
1. Connect the furnace thermocouple output cables (MTS cable 525655-xx).
Temperature measurements are provided through a Type K (Type “R”
optional) thermocouple lead for each zone. The thermocouple assembly
should be connected to the rear furnace panel. The other end should be
plugged into the outlet labeled “J1” or “J2” on the temperature controller
bottom panel.
The furnace/controller must be connected to a supply source which
incorporates a residual current operated circuit-breaker which interrupts the
supply at a differential current of 30 mA or less.
Due to the fact that the heaters are hazardous live and are accessible, the
equipment must be connected to a supply source that incorporates such a circuit
breaker.
2. Connect the furnace power input cables (MTS cable 518818-xx).
Socket style connectors “J4” and “J5” transfer the heater control signal (line
voltage) from the temperature controller to the furnace heater elements.
