8.1 The hand never connects to the robot system
8.1.1 Problem
The user interface says that the device is not connected even if it should be.
8.1.2 Solution
The first steps to try to solve the issue are the followings:
Check whether the wiring is correct, cf.cable connections(see Page 14).
Make a power cycle:
If the hand is connected to the power source of the UR Control Box, make a power cycle of the
robot.
If the hand is connected to an external power source, make a power cycle of the qb dummy.
WARNING:
Please, also have a look at each connector and check if any is damaged.
Do not force a connector plug if it seems not to match properly its location. It may be
already damaged and you could brake it completely!
