3.11 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
If the controller is configured to use the same relay for more than one function, then the
following priority is used to determine how the relay functions: Control Outputs take
precedence over Alarms, which in turn take precedence over Time/Events, which in turn
take precedence over Logic Gate Outputs. For example, if you select the Loop 2 Output
Algorithm as Time Simplex (which uses Relay 3), enable Alarm 3 (which also uses
Relay 3) and configure a Logic Gate to use Relay 3, then the instrument will use Relay
#3 to perform the Time Simplex output and ignore the Alarm and Logic Gate functions.
The Tuning Group is automatically configured to have two PID sets when a Duplex
Control Algorithm is selected.

Definition
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 relay output, then
none of the prompts that need a relay output will
appear. See Table 2-6 and Table 2-7 for other
information about output types.
ATTENTION For all Duplex Output forms, PID heat
parameters (PID Set 1) apply for controller output
greater than 50 %; PID cool parameters (PID Set 2)
apply for controller output less than 50 %.
TIME SIMPLEX—This output algorithm uses Relay1
for Time Proportional Control. Time Proportional
Output has a resolution of 3.33 milliseconds with an
adjustable Cycle Time (see Section 3.4).
