9.2 Configuring Alarm Parameters
9.2.1 Choosing the Alarm Action
The first step in configuring an alarm is to choose the alarm action. The choices are:
• OFFOFF (off) – The alarm will not be used.
• nornor (normal) – The LED will be lit (and the optional alarm output activated)
when the process value triggers the alarm and be turned off when the alarm
condition has been cleared.
• LatLat (latching) – Once the LED is lit (and optional alarm output activated),
the LED will remain lit (and the output will remain in the alarm state) until the
operator presses the key, even if the alarm condition has cleared before
the operator presses the key.
• EuntEunt (event) – This special use of an alarm LED (and optional alarm output)
indicates that the controller has reached a particular point in a ramp/soak
recipe. Setting the alarm action to “event” reserves the alarm for use by a
ramp/soak recipe. However, the specific recipe event(s) that will trigger the
alarm are configured using the r-Sr-S (ramp/soak) menu as described in 11.4.
