Alarm Delay

You can set the CAS200 to delay normal alarm detection

and alarm reporting. There are two kinds of alarm delay:

• Startup alarm delay delays detection of process

alarms (but not failed sensor alarms) for all channels

for a time period you set in the Setup Global

Parameters main menu.

• Channel alarm delay delays failed sensor alarms and

process alarms for one channel until the alarm

condition is continuously present for longer than the

channel alarm delay time you set.

NOTE! Failed sensor alarms are detected at startup. They

are affected by the channel alarm delay, not the

startup alarm delay time.

High Process Alarm Setpoint

This menu lets you select the setpoint (temperature or

other value within the scaled sensor range) at which the

high process alarm activates. The high process alarm

activates when the process variable (PV) goes above the

high process setpoint. It deactivates when the PV goes

below the high process setpoint minus the deadband value,

if you have set a deadband value.

Selectable values: Any point within the scaled sensor

range

High Process Alarm Type

This menu lets you turn off the high process alarm or set it

to one of the alarm functions. (See the previous description

for an explanation of these choices).

Selectable values: Off, Latched, Unlatched
