PRECAUTIONS FOR DISCONNECTION AND CONNECTION OF CON-
NECTORS
NOTICE
• Controller has been assembled with electronic circuits
for control including microcomputers. These electronic
circuits inside of the controller must be handled with
care since they control the machine.
• Do not leave things on the controller.
• Cover the connector portion of the controller with a
tape and a plastic bag. Do not touch the connecting
portion of connector.
• Do not leave the controller in a place where it is ex-
posed to rain.
• Do not place the controller on oil, water, soil or any pla-
ces where the temperature is likely to be high even for
a short period of time (Place it on a suitable dry stand).
Precautions for troubleshooting electrical circuits
•
Be sure to turn the starting switch to OFF position before disconnecting or connecting the connectors.
•
Before performing troubleshooting, check all the related connectors for loose connection.
REMARK
Check the related connectors for their performance by disconnecting and connecting them several times.
•
Be sure to connect all the disconnected connectors before proceeding to the next step.
NOTICE
If the starting switch is turned to ON position while the connectors are disconnected, an unrelated
failure beside the actual failed part may be displayed.
•
When performing the troubleshooting for the circuit (measurement of voltage, resistance,continuity, current,
etc.), shake the related wiring harnesses and connectors several times and check that the multimeter read-
ing does not change.
NOTICE
If the value changes on the multimeter, there may be a defective contact in the circuit.
