Note.

High/Low Latch Alarms

– An alarm becomes active when the process variable

value rises above the high latch alarm trip point value or falls below the low
latch alarm trip point value. The latch alarm trip point values are configured
in engineering units in the Set Up Level (Level 2). The alarm remains active
until it is acknowledged and the alarm process condition is removed. The
alarm can be acknowledged using the keys on the instrument front panel
(see page 3) or via the volt-free digital input once it has been configured to
provide a remote alarm acknowledge facility.
