July 2013 3.29 MB 720 (FS) machine operating panel 337
NC Start and NC Stop are normally open contacts on the MB (FS).
Please note that the MB 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.
The interface is electrically separated (protective extra-low voltage (PELV)
as per EN 61800-5-1).
