This is the simplest system with 1 motor. It can be operated with an integrated or surface-mounted switch, not included.

Operation of one or more drives is controlled by a control box with rectifier that is connected to the electricity network.

- Automatic stop in case of unequal load or overload
Depending on the features we will recommend a suitable control box type.

It is of life importance that an emergency door opens after a break down of the electrical system. For those reasons a control box can be provided with a built-in emergency power pack.
