Good afternoon My colleague is currently on site trying install a 2F85 gripper on a UR5 robot and he is having some issues. He has mounted the gripper and connected to the controller as per the instructions. When he goes to power up the gripper from the dash board on the UR teach pendant the light on the gripper turns from Blue to Flashing Blue/Red and will not power up…?? Do you have any suggestions as to why this is happening.??
