Output Override Digital Input
To enable the output override feature, select a digital input. When the specified input is activated,
the controller sets all loops to manual mode at the output levels specified at the SENSOR FAIL HT
OUTPUT and SENSOR FAIL CL OUTPUT parameters in the SETUP LOOP OUTPUTS menu.

OUTPUT OVERRIDE
DIG INPUT? NONE
Selectable values: NONE or input number 1 to 8.
Use the next parameter, OVERRIDE DIG IN ACTIVE, to set the signal state that activates the
output override feature.
WARNING! Do not rely solely on the output override feature to shut down your process.
Install external safety devices or over-temperature devices for emergency shutdowns.
Override Digital Input Active
Specify whether a low or high signal activates the output override feature (see OUTPUT OVERRIDE
DIG INPUT above).
ALARM
OVERRIDE DIG IN
ACTIVE ? LOW
Selectable values: HIGH or LOW.
You can set the input to be active when low or active when high. When the input selected for
OUTPUT OVERRIDE DIG INPUT changes to the specified state, all the loop’s outputs are set to
their sensor fail levels.
Startup Alarm Delay
Set a startup delay for process and deviation alarms for all loops. The controller does not report
these alarm conditions for the specified number of minutes after the controller powers up. This
feature does not delay failed sensor alarms.
