MB 720 FS:
With the MB 720 FS, the EMERGENCY STOP is evaluated through two
channels by the control via HSCI and is normally wired via connector X18.
General information on the emergency stop button:
Emergency stop buttons are to be used exclusively for emergency stop
purposes. Under normal operating conditions, a machine must not be
switched off via the emergency stop buttons. The proper functioning of all
emergency stop buttons is to be tested annually by pressing these buttons.
X7: PLC outputs Pin layout:
In the event of an overload or short circuit and as a consequence of excessive
temperature, the individual PLC outputs switch off automatically. Then the
outputs will try to switch on again cyclically.
Note
With the MB 720 without FS, the EMERGENCY STOP must be wired
externally in the EMERGENCY STOP chain as before.
