Setup

Output Override Digital Input

Use this menu to set a digital input that sets all loops in manual output at
output levels you select in the Outputs menu. This menu, and the next
one, let you configure a “panic button” or “kill switch” that sets all
outputs to the output override percentage you set in the Set up Loop
Outputs
main menu.

Selectable values: NONE or input number 1-8.

WARNING

Watlow Anafaze recommends that you install additional
external safety devices or over-temperature devices for
emergency shutdowns. Do not rely solely on the output
override feature to shut down your process.

Output Override Input Polarity

Use this menu to toggle the polarity of the Output Override digital input.
You can set the input to be active when Low or active when High.

Selectable values: High or Low.

Start-up Alarm Delay

Use this menu to set a start-up 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. (The
controller will always report failed sensor alarms, no matter what start-
up delay you set.)

Selectable values: 0-60 minutes.
