Sensor break alarm
The function that alarm output will be ON when sensor is not connected or when sensor's disconnection is detected during temperature
controlling. You can check whether the sensor is connected with buzzer or other units using alarm output contact. It is selectable between
standard alarm [ SBaA ], or alarm latch [ SBaB ].

Description
If it is an alarm condition, alarm output is ON. If it is a clear alarm condition, alarm output is OFF.
If it is an alarm condition, alarm output is ON and maintains ON status. (Alarm output HOLD)
First alarm condition is ignored and from second alarm condition, standard alarm operates.
When power is supplied and it is an alarm condition, this first alarm condition is ignored and from the
second alarm condition, standard alarm operates.
If it is an alarm condition, it operates both alarm latch and standby sequence. When power is supplied
and it is an alarm condition, this first alarm condition is ignored and from the second alarm condition,
alarm latch operates.
First alarm condition is ignored and from second alarm condition, standard alarm operates.
When re-applied standby sequence and if it is alarm condition, alarm output does not turn ON.
After clearing alarm condition, standard alarm operates.
Basic operation is same as alarm latch and standby sequence 1. It operates not only by power ON/OFF,
but also alarm setting value, or alarm option changing. When re-applied standby sequence and if it is
alarm condition, alarm output does not turn ON.
After clearing alarm condition, alarm latch operates.
Economical PID Control
Set both alarm operation and alarm option by combining.
Each alarm operates individually in two alarm output models.
When the current temperature is out of alarm range, alarm clears
automatically. If alarm option is alarm latch or alarm latch and standby
sequence 1/2, press digital input key( +
key[DI-K] of Parameter group 2 set as AlRE), or turn OFF the power
and turn ON to clear alarm.
