2.2.2.5 Enabling control device
The 5MP7251.101P-000 is equipped with an enabling control device. The enabling control device consists of a
three-position operating element. A significant feature is the dual-circuit design and direct opening action of the
third switch position per EN 60947-1 and EN 60947-5-8.
Danger!
Suitable measures and precautions must be in place to detect or prevent mechanical securing or any
other manipulations that give the impression of safe operation
(reasonably foreseeable misuse
). Op-
erating a manipulated MP7200 is not permitted.
Warning!
The enabling control device must be tested periodically (every 6 months) by actuating it to the panic
position. This test must be performed to determine whether the panic position is functional.

2.2.2.5.1 Normal actuation
The following figure shows the circuit diagram and switching paths of the enable switch during normal actuation.
Both circuits behave the same way. Enable position "ac" is implemented to compensate for differences in actuating
pressure during operation. After releasing enable position "re", the device returns to zero position "nu" for enabling
control.
