July 2013 3.27 MB 620 machine operating panel 323
X101: Power supply Pin layout:
Power consumption of the operating panel units without HR handwheel and
controlled inputs/outputs:
Power consumption of the MB 620: 4.0 W
Power consumption of the PLB 6001: 5.0 W
X30: Handwheel
connection,
permissive button /
emergency stop
With the MB 620 without functional safety (FS), the permissive buttons and
the EMERGENCY STOP of the handwheel must be wired externally in
corresponding safety circuits as before.
Pin layout of MB 620 FS:
The emergency stop inputs (pin 6 and pin 8) are active even if the HR
handwheel has been deactivated via machine parameter MP7640. It is
therefore always necessary to wire the emergency stop inputs correctly.
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.
Connection X30 not used on MB 620 without FS.

Please note that the MB 620 is powered by +24 V NC.
For the entire HSCI system, the +24 V NC supply voltage is required to be
safely separated voltage. The +24 V NC supply voltage must not, under any
circumstances, be connected with the +24 V PLC supply voltage, because
this removes the double basic insulation.
