Introduction

Output algorithm group prompts

This data deals with various output types in the controller, the Digital Output Status, and the Current Duplex functionality.

Table 4-6 lists all the function prompts in the Output Algorithm Set Up group and their definitions.

Definition

The OUTPUT ALGORITHM lets you select the type of output you want. Not applicable with Control algorithm prompt 3PSTEP.

Selections are hardware dependent. For example, if the controller does not have a current output, then none of the prompts for Output Algorithms that need a current output will appear. Likewise, if the controller does not have a relay output, then none of the prompts that need a relay output will appear.

ATTENTION For all Duplex Output forms, PID heat parameters apply for controller output greater than 50 %; PID cool parameters apply for controller output less than 50 %.

TIME SIMPLEX— This output algorithm uses Digital Output 1 for Time Proportional Control. The output is updated per the Loop sampling rate selection. Time Proportional Output has a resolution of 4.44 msec. Cycle Time is adjustable from 1 to 120 seconds.

CURRENT SIMPLEX— Type of output using one 4 mA to 20 mA signal that can be fed into a positive or negative grounded load of 0 to 1000 ohms. The signal can be recalibrated for any desired range from 4 mA to 20 mA for 0 % to 100 % output.

POSITION PROPORTIONAL SIMPLEX— Type of output using two SPDT relays and a motor which has a 100 to 1000 ohms feedback slidewire.

Forces Input 2 to SLIDEW selection.

ATTENTION Position Proportional is not available on two-loop or cascade controllers.

Other prompts affected: DEADBAND, IN2 TYPE

TIME DUPLEX— This output algorithm uses Digital Outputs 1 and 2 for Duplex Time Proportional Control. The outputs are updated per the Loop sampling rate selection. Time Proportional Output has a resolution of 4.44 msec. Cycle Time is adjustable from 1 second to 120 seconds.
