3 Installation
1. Using Table 3-1 and circuit schematics you have prepared, make up a cable to connect the
various system components which are to be controlled. Unambiguous labeling of each lead
will help prevent costly mistakes.

2. Ensure that the Process Control channel override switches are all set to off.
3. Connect the component end of the cable to the system component to be controlled.
4. Plug the connector into the back of the Control Unit.
5. Refer to Section 4.11 on page 4-26 for instructions for setting setpoints.
3.7 Connecting Stabil-Ion Remote Control
Front Panel of Control Unit (with Door Open) Showing Locations of Override
Switches.
This factory installed option permits the following functions to be controlled from a remote
location:
■ Ionization gauge IG1/IG2 on/off ■ Pressure range selection
■ Degas on/off ■ Ionization gauge lockout
■ Cathode select 1 or 2 ■ Front panel switch disable
In addition, the following functions are outputted in the form of relay contact closures which can
signal the status of the instrument to a remote location, or control external devices.
■ IG-1 on/off ■ Degas on/off
■ IG-2 on/off ■ Circuit fault detection
The optically isolated control inputs are on a 26 pin remote input connector. The relay contact
outputs are accessible on the 15 pin remote output connector.
