Identify Your Wiring Requirements

To determine the appropriate diagrams for wiring your controller, refer to the model number interpretation in this section. The model number of the controller is on the outside of the case.

Universal Output Functionality and Restrictions

Instruments with multiple outputs can be configured to perform a variety of output types and alarms. For example, an instrument with one current output and two relays can be configured to provide any one of the following:

1)Current Simplex with two alarm relays

2)Current Duplex 100% with two alarm relays

3)Time Simplex with one alarm relay

4)Time Duplex with no alarm relays

5)Three Position Step Control with no alarm relays

These selections may all be made via the keyboard and by wiring to the appropriate output terminals; there are no internal jumpers or switches to change. This flexibility allows a customer to stock a single instrument which is able to handle a variety of applications.

Table 2-6shows what control types and alarms are available based upon the installed outputs. In this table, when Duplex Control and Reverse Action are configured:

Output 1 is HEAT and Output 2 is COOL.

In Table 2-6when Three Position Step Control is configured:

Output 1 is OPEN and Output 2 is CLOSE.

In Table 2-6the Output 1/2 option Single Relay can be any of the following selections: Electro-Mechanical Relay, Solid-State Relay or Open Collector Output.
