7.4 Alarms
Alarm (ALM) function sets up the alarm status when the measured value (PV) or the deviation reaches
the alarm set values. In the alarm status, the alarm output is output, and the alarms are used to drive the
equipment danger signals or the safety equipment.
The output specifications are the relay contact output or the open collector output.
(Specify when ordering)
(1) Deviation alarm
If the deviation [Measured value (PV) - Set value (SV)] reaches the alarm set value, the alarm status is
set up. Consequently, if the set value (SV) changes, the alarm set value will also change.
Deviation high alarm
When the deviation [Measured value (PV) - Set value (SV)] is the alarm set value or more, the alarm
status is set up.
When the deviation is on the positive side When the deviation is on the negative side
