14.2 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 2.2.2.)
• While pressing and holding an operation switch or emergency stop switch, check the
conductivity between wires (pins) of the external cables, relay cable shown in the table
below.
If the conductivity is not given, wire breakage or poor contact is 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.
