Hi Pros!

We have a case where multiple robots are working together. Robots are inside safety fences and the door is monitored with safety rated door switch.

Sometimes robot program needs minor modifications. For example our product infill boxes are a bit different in every batch so we need to adjust picking routine movements.

Before implementing robot cell, we are evaluating different options to make a adjustments. Obviously door opening will trigger safety stop for the robots and then program modifications cannot be done by moving robot arm.

How people have solved this situation? Is the only option to use operational/manual mode together with three position enabling device?

We are using CB3 robots.

Many thanks in advance!

    Maybe you could have a kind of key switch to by pass the door switch ?

    The person in charge could have the key and by pass the door safety to program the robot.

    @cobottiukko what we did inhouse is simply a jumper with a big huge red tag that we put in the robot and on the door while we reprogram. What we intend to do in the future is to have a deadman switch for the reprogramming, but then that's only a wish for now.
