Before and After Acknowledging
an Alarm
To display the active PID set
1. Press MENU to reach Tuning Mode.
2. In TUNING Mode, press MENU to reach the correct Menu parameter.
3. The active PID set will have an asterisk (*) on both sides of the value.
ALARM OPERATION
Alarms may be used in systems to provide warnings of unsafe conditions. All
535 operators must know how the alarms are configured, the consequences
of acknowledging an alarm and how to react to alarm conditions.
Alarm Indication
• lit icons ALM 1 and/or ALM 2
• lit ACK key
• displayed alarm message
Acknowledgable alarms meet the first two of these conditions.
Non-acknowledgable alarms only meet the first condition (only icon is lit).
To acknowledge an alarm(s):
1. To acknowledge Alarm 1, press ACK once.
2. To acknowledge Alarm 2, press ACK twice.
3. If both alarms are activated, press ACK once to acknowledge Alarm 1, then
again to acknowledge Alarm 2.
4. The message and alarm icon dissappear.
Latching Alarms
If an alarm is set up to be latching (for details, see Chapter 5) then, in general,
it must be acknowledged in order to clear the alarm and release the relay (if
applicable). A non-latching alarm will clear itself as soon as the process leaves
the alarm condition.
NOTE:
All alarms are software alarms unless
tied to an output relay in the SET UP
mode. See Chapters 5 and 7 for details
on alarms.
NOTE:
Powering down the 535
acknowledges/clears all latched
alarms. When powering up, all
alarms will be reinitialized.
