Emergency STOP
The emergency stop button immediately disconnects the PBD from all the external connection,
which ensure the safety of the controller. By pressing the emergency stop button, the device will
be locked in the "off" position. Only after removing all faults, release the emergency stop button
by rotating it clockwise, can the controller resume working normally.
