Due to its placement, the STOP button is equally accessible to both left-handed and right-
handed individuals.
Due to its profiled design, the STOP button is easily accessible. The STOP button is fall
protected by a special collar. As a result, while the STOP button can still be triggered if the
Mobile Panel 177 is dropped, it is nonetheless largely protected from damage.
Operation
The STOP button is operated by pressing the button. Once the stop operation has been
initiated, the STOP button remains engaged in the stop position.
Note
The STOP button engages compulsorily when activated.
Releasing the STOP button
Warning
If you activate the STOP button, thus bringing the system being monitored to a standstill, you
may only release the STOP button if the reason for stopping the system has been eliminated
and a safe restart is provided for.
To release the STOP button, it must be turned in a clockwise direction. The STOP button
then returns on its own to the starting position.
