If ASEt does not appear on the display refer to the Enable mode section of this manual for
directions on how to determine if the ASEt mode is enabled. If ASEt appears on the display,
but pressing the DOWN key causes the display to change to oFF, this indicates that no
alarm(s) have been selected in the Program mode.
ALARM OPERATION
There are two types available per pen, Process Direct or Process Reverse. These are
selected in the Program mode.
Process Alarm Direct - the alarm will be ON if the process value is greater than the process
alarm value selected in the Alarm Set mode.
Process Alarm Reverse - the alarm will be ON if the process value is less than the process
alarm value selected in the Alarm Set mode.
The alarms will be active while the instrument is in the Operate mode.
Alarm output chatter can be reduced by using the hysteresis (adjusted in Program mode) to
create a deadband around the alarm point.
