Electronics
Side Panel Connectors
The side panel ( Figure 36 ) contains several connectors, the
primary fuses, and several status LEDs. Most of these
components are part of the AC board or the LAN/MS control
card and extend through the side panel.
High vacuum power (HIVAC POWER) connector
The high vacuum power connector carries power for the turbo
controller from the AC board.
Primary fuses
The primary fuses limit current into the MSD in case of a short
circuit in the foreline pump. The primary fuses are on the AC
board.
Power cord receptacle
The AC power cord brings in all electrical power for the MSD.
The power cord can be detached from the instrument.
Foreline pump power cord receptacle
The foreline pump power cord receptacle provides AC power for
the foreline pump. If the power switch is off, no power is
supplied to the foreline pump.
Remote start connector
The remote start connector is the external connector for the
remote start circuitry on the LAN control card. It combines the
readiness condition and start/stop events signals from the GC
control system and the MSD control system for synchronized
communications with other instruments.
GC-LAN and MSD-LAN (I/O) connectors
The GC and MSD LAN cables from the data system are
connected to the I/O LAN connectors. These cables carry all
data communication between the PC and the instrument.
