Cause and
correction
Assumed cause
Correction
Prevention
More than the maximum number of
Sensors are connected.
This event occurs when the cause of
the error is removed and communica-
tions for the relevant slave recover.
Simply reset the error in the Control-
ler.
Do not connect more than the maxi-
mum number of Sensors.

Assumed cause
Correction
Prevention
The set value does not match the
number of Sensors that are actually
connected.
If the setting of the number of con-
nected Sensors is incorrect, correct
the set value. If the number of Sen-
sors that are connected is incorrect,
correct the Sensor connections and
cycle the power supply. If the number
of Sensors are decreased in discon-
necting Distributed Sensor Unit,
re-connect the Distributed Sensor
Unit.
Make sure that the setting of the num-
ber of connected Sensors agrees with
the number of Sensors that are actu-
ally connected.
Attached
information
None
Precautions/
Remarks
The case that the number of Sensors is decreased in disconnecting Distributed Sensor Unit is applicable. The case
that the number of Sensors is increased in connecting Distributed Sensor Unit is not applicable.
