Safety Interlock
The VacIon Plus pump feedthrough in conjunction with the cable P/N
929-0705, -0707, 0708 and -0709, when used with the Agilent control
units, allows the operation of the “High Voltage Cable Safety
Interlock” feature.
When the high voltage cable connector is disconnected from the
VacIon Plus pump feedthrough, the high voltage is automatically
switched off by the control unit.
Heater Installation
The heating element (Fig. 21) is composed of two plates to be fixed to
the pump case.
NOTE
It is advisable to make a 10 – 15 minutes initial operation of the heater in a
ventilated room to allow the evaporation of residual internal alloying elements.
To install the element proceed as follows (Fig. 22):
1
Before removing the pole pieces, mark their position and
orientation for an easier assembly later on.
2
Position the heating plate (1) inserting the threaded pins
positioned on the pump jacket into the holes of the plate. Be sure
that the written heating plate side is towards you;
3
Position the other heating plate (2) in the same way as the
heating plate (1);
4
Reinstall the pole pieces;
5
Position the connection box (3) on the upper side of the pump in
an oppose position of the HV feedthrough with respect to the
flange, and fix it to the pump case.
