5.2.2 When an operation switch or emergency stop switch does not operate
When an operation switch or emergency stop switch does not operate, check the following
points.
• Check whether external cables are connected correctly to the Handy GOT. (Refer to chapter
3)
• While pressing and holding an operation switch or emergency stop switch, check the
conduction between the wires (pins or terminal blocks) of the external cables and relay
cable in the table below.
If no conduction is confirmed, wire breakage or poor contact may be present in the external
cable or relay cable, or the circuits inside the Handy GOT may be damaged.
If it is suspected that the circuits inside the Handy GOT are damaged, consult with a
Mitsubishi Electric distributor.
