Installation
Model 409 High Temperature Controller Connections
All input/output signals that interface the temperature controller and other system
components are available on the bottom panel. This section provides information
on all input/output signals of the temperature controller.
Model 409.83 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 30mA 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.
Chassis voltage
The temperature controller receives power from a detachable, three-wire power
cord. The power cord plugs into an input power connector block located on the
bottom panel. The chassis power switch is located on the rear panel; on is labeled
|, and off is labeled 0. The line voltage is selected at time of order (120 or 240 V)
and is not field selectable.
J1, J2, J3
thermocouple inputs
Temperature feedback is provided through a single Type ‘R’ thermocouple lead
(for each zone). The furnace thermocouples should be connected to the input
connectors. The connections are polarized; the longer slot is negative (–) and the
shorter slot is positive (+).
