Error Detection
Method
Errors are detected based on open circuit in external input terminals (J1-JC).
Error Generating
Conditions
When external input terminal (J1-JC) is shorted during operation (“Overall Alarm” must be set in field
setting mode).
Possible Causes
■
Faulty external device
■
Broken wire
■
Faulty control PCB
Troubleshooting
Measure resistance
between external
input terminals
(J1-JC).
Is
resistance
200
Ω
or
lower?
YES
YES
Remove the cause of error in
connected external device.
Check wires for abnormalities
(broken wire, faulty contact,
etc.).
Replace control PCB.
Is
connected
external device
operating
properly?
NO
(HF002)
NO
