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.
