3.2 Stabil-Ion Gauge Installation
■
The Stabil-Ion Gauge is double packaged at the factory for cleanroom compatibility. To reduce
the chance of contamination, do not remove a Stabil-Ion Gauge from its inner bag until
moments before it is to be connected to the vacuum system.
NOTE: The Stabil-Ion Gauge is packaged with its corresponding Memory Module containing
data for that specific gauge. Take note of the Serial number of the Gauge and record it before
mounting.
■
Any mounting orientation may be used. However,
to minimize the possibility of excessive
temperature at the electrical connector when
degassing, it is best not to install the Stabil-Ion
Gauges with the electrical connector above the
gauge. If it is necessary to install the gauge with the
connector on top, degas time must be limited to 10
minutes/hour. See Section 4.3.4.2 on page 4-12.
When mounting horizontally, the ventilation slots
in the Guard will be oriented for best cooling if the
gauge is installed with the locating key in the pin
guard on the bottom. See Figure 3-1 and Figure
3-2. Note in Figure 3-2 that the cable will exit in
the direction the locating key is oriented.
Verify that the vacuum port to which the Stabil-Ion Gauge is mounted is
electrically grounded. It is essential for personnel safety as well as proper
operation that the envelope of the gauge be connected to a facility ground.
Use a ground lug on a flange bolt if necessary.
Protect the Memory Module from static electricity. Touch a grounded,
unpainted metal surface on the Stabil-Ion Control Unit and then touch the
surface of the anti-static bag before removing the Memory Module from its
bag.
