Hardware Overview
8.2.6 BMPC/2 Line Control Unit
The BMPC/2 Line Control Unit is used as an interface between the BMPC/2 control unit,
the vacuum pumps and their corresponding valves. All fuses, motor protection switches,
conductors and relays needed for the function of the BMPC/2 are part of this unit.
The line control unit is located in the upper rear part of the BMPC/2. To access the line
control unit, you have to open the upper rear door using a screwdriver to turn both
screws (quarter turn to the left). The door can then be easily removed.
