AUXILIARY OUTPUT HIGH SCALING

 

 

 

Engineering Units

 

 

 

FACTOR— This is a value in engineering

 

 

 

 

 

 

 

 

units used to represent all AUX OUT

 

 

 

 

 

 

 

 

parameters except Output.

 

 

 

 

 

 

 

 

For Output, this is a value in percent and can

 

 

 

 

 

 

 

 

be any value between –5 % and +105 %.

 

 

 

 

 

 

 

 

However, keep in mind that relay output

 

 

 

 

 

 

 

 

types can only be scaled 0 % to 100 %.

DIGITAL INPUT 1 SELECTIONS—All

 

 

 

 

 

 

 

 

selections are available for Input 1. The

 

 

 

 

 

 

 

 

controller returns to its original state when

 

 

 

 

 

 

 

 

contact opens, except when overruled by the

 

 

 

 

 

 

 

 

keyboard.

TO MANUAL—Contact closure puts the

 

 

 

 

 

 

 

 

affected loop into manual mode. Contact

 

 

 

 

 

 

 

 

open returns controller to former mode.

TO LOCAL SETPOINT—When a remote

 

 

 

 

 

 

 

 

setpoint is configured, contact closure puts

 

 

 

 

 

 

 

 

the controller into local setpoint 1. When

 

 

 

 

 

 

 

 

contact opens, the controller returns to

 

 

 

 

 

 

 

 

former operation—local or remote setpoint—

 

 

 

 

 

 

 

 

unless SETPOINT SELECT key is pressed

 

 

 

 

 

 

 

 

while digital input is active. If this happens,

 

 

 

 

 

 

 

 

the controller will stay in the local setpoint

 

 

 

 

 

 

 

 

mode when contact opens.
