Kindly, how can we keep the safety ensured on safety doors at high speeds, without stopping the machine at low speeds (if a door is opened).
Our customer needs to run at low speed (with doors opened and alarm horn on), so he can do some operation settings. Of course, to enable the run at high speeds, the doors should be closed.
We are using a safety switch installed on each door, and the switch contacts are wired to a safety relay (double circuit).
So, it is not clear how to enable or disable the safety doors, depending on machine speed, without endangering the safety.
Thank you
