•Separate External Wiring—Separate connecting wires into bundles

(See Permissible Wiring Bundling - Table 2-4)and route the individual bundles through separate conduit metal trays.

Use Suppression Devices—For additional noise protection, you may want to add suppression devices at the external source. Appropriate suppression devices are commercially available.

ATTENTION

For additional noise information, refer to document number 51-52-05-01, How to Apply Digital Instrumentation in Severe Electrical Noise Environments.

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 2-5shows 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.
