• Alarm status: The internal alarm status is turned on when an alarm occurs and
turned off in normal condition
• Alarm output status: Contact output status when an alarm occurs (ON in alarm
condition and OFF in normal condition)
However, the output status depends on the settings of energized/de-energized of alarm,
latch action, and contact type.
The above assumes that the contact type is energized. (Then contact is turned on when
an event occurs.)
To output the normal alarm to the contact output, assign the alarm output status.
► Alarm action: 11.1 Setting Alarm Type
Alarm Latch Status
The alarm latch status can be output to another contact output irrespective of the setting
of alarm-1 to -4 type (AL1 to AL4). (The setpoints below are I relay numbers.)
