Configuration
3.8 Output Set Up Group
Introduction
This group deals with various output types in the controller, the Digital Output Status and
the Current Output operation.
ATTENTION
The Tuning Group is automatically configured to have two PID sets
when a Duplex Control Algorithm is selected.

Definition
OUT ALG
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
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
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. This
signal can easily be configured for 4-20 mA or 0-20
mA operation via the CO RANGE configuration,
below.
POSITON
POSITION PROPORTIONAL —Type of output using
two relays and a motor that has a 100 to 1000 ohms
feedback slidewire.
This output algorithm selection forces Input 2 to the
SLIDEW selection when the Control Algorithm is any
selection other than 3PSTEP.
