This document provides installation instructions and application information for the Edwards ATC and APG to Varian CT-100 Pin Adapter. It also explains the differences between the CT-100 and Edwards gauges.
The document provides instructions for connecting the L7439301 Pin Adapter to enable the installation of a Varian CT-100 Active Rough Vacuum Gauge into systems originally equipped with Edwards Active Thermocouple (ATC) or Active Pirani (APG) gauges. The adapter connects via an RJ45 connector, allowing users to proceed with the CT-100 installation according to its specific manual.
The guide highlights that while the gauge ID signal is not available in the CT-100 version, all other functions are maintained. It notes a difference in analog output calibration between Edwards and Varian gauges, advising that system changes may be necessary for accurate pressure display unless setpoint outputs are used as status signals. A pin equivalence chart details the wiring connections.
The adapter enables installing a Varian CT-100 Active Rough Vacuum Gauge into systems using an Edwards gauge without removing the existing cable.
The gauge ID signal is not available because the CT-100 does not support it.
