Alarm Screen Example
This is an example of what a typical Alarm screen looks like. The user will see the message
causing the alarm in the top half of the display with an ALARM SILENCE button in the
lower half.
To turn off the alarm, the user must press the ALARM SILENCE button. This will cancel
the alarm.
See Section 7-4: Alarms on p. 57 for alarm descriptions.
4-5 Redundant Safety Controller Display
Optional
The Redundant Safety Controller limits the process air temperature from exceeding specific
temperatures in case of a catastrophic failure of the primary PLC process air temperature
control system. The controller is a modular, self-contained unit removable from the
mounting housing. All parameters are factory set and adjusted; normally, no field adjustment
to the internal controls is necessary.
