Alarm Selections
1. Alarms will activate only when the Temperature Controller is in the RUN
mode. When an alarm occurs, the alarm relay will energize, the alarm
LED will flash, the audible alarm will sound intermittently and the display
will flash the type of alarm. There are three possible alarm mode selec-
tions: MANUAL RESET, AUTO RESET, or OFF. Refer to Figure 12.
2. If you select ALARM SETPOINTS - OFF, no process or deviation alarms
will actuate. Both AUTO RESET and MANUAL RESET will result in alarms
actuating. If you select AUTO RESET, the relay will automatically shut off
when the PV temperature falls out of the alarm setpoint temperature. For
MANUAL RESET, the alarm relay is turned off when the ALARM key is
pressed. The alarm LED remains on until the alarm condition clears. For
both AUTO and MANUAL, the flashing message and the audible alarm are
turned off.
3. The first Alarm screen will display ALARM SETPOINTS - MANUAL RE-
SET. Refer to Figure 13.
