10.1 ALARM OUTPUT PATTERN
The alarm output pattern, normal output (‘NORMAL’) where alarm trips according to the setpoint, or zone output (‘ZONE’)
where alarm trips and resets between each setpoint, can be selected. The default setting is normal output.
IMPORTANT
• Alarm trip action setting is disregarded with zone alarm.
• If a setpoint is set to invalid (‘-----’), no output is provided for the zones adjoining the setpoint (e.g. P and L are not pro-
vided with L set to invalid).
