1
Jiggle the detector connectors (drive unit
side and detector side) and check if they are
disconnected.
The connector is disconnected (or loose).
Correctly install.
The connector is not disconnected.
Check the investigation item No. 2.
2
Is the detector cable wired in the same
conduit as the motor's power cable, or are
the two cables laid in parallel near each
other?
The cables are wired near each other.
(Noise is entering from the power cable.)
Improve the cable wiring.
The wires are sufficiently separated.
Check the investigation item No. 3.
3
Is the motor FG wire connected only to the
drive unit which drives it?
(Is the motor grounded to one point?)
The motor FG wire is grounded on the motor
side.
Ground the motor to one point, connecting
the wires together on the drive unit side.
The motor is grounded to one point.
Check the investigation item No. 4.
4
Turn the power OFF, and check the detector
cable connection with a tester. (Is the cable
shielded?)
The connection is faulty.
Replace the detector cable.
The connection is normal.
Check the investigation item No. 5.
5
Replace with another unit, and check
whether the fault is on the unit side or
detector side.
The alarm is on the drive unit side.
Replace the drive unit.
The alarm is on the detector side.
Check the investigation item No. 6.
6
Check if there is any abnormality in the
detector's ambient environment.
(Ex. Ambient temperature, noise,
grounding)
Take remedies according to the causes of the abnormality in the ambient environment.
