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 a current output and two relays can be
configured to perform any 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; or
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 2-6 shows 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 while "Output 2" is COOL. When Three Position Step Control is
configured, "Output 1" is OPEN while "Output 2" is CLOSE. The Output 1/2 option
"Single Relay" can be any of the following selections: Electro-Mechanical Relay, Solid-
State Relay or Open Collector Output.
