Alarm Delay
This menu sets a Channel Alarm Delay. There are two types of Alarm Delay: the
Startup Alarm Delay, and Channel Alarm Delay. Startup Alarm Delay (which you
can set in the Setup Global Parameters main menu), delays process alarms for
all channels for a specified time after the Scanner powers up.
The Channel Alarm Delay, in contrast, is set separately for each channel. It
delays process alarms until the alarm condition has been continuously present
for longer than the alarm delay time.
Selectable Values: 0 to 255 seconds.
Manual I/O Test
Press at this prompt to see menus which can help you test the digital inputs,
digital outputs, and the Scanner keypad.
Digital Input Testing
This is a read-only menu that shows the logic state of the 8 digital inputs as H
(High- the input is at 5 volts or is not connected) or L (Low – the input is at zero
volts). Inputs 1 to 8 are displayed from left to right. Since inputs are pulled High
when they are not connected, test an input by shorting it to controller common
and making sure this menu shows the correct state for that input.
