REMOVING / REPLACING THE RELAY PCA FROM THE INSTRUMENT

This is the most commonly used version of the Relay PCA. It includes a bank of solid state
AC relays. This version is installed in analyzers where components such as AC powered
heaters must be turned ON & OFF.
A retainer plate is installed over the relay to keep them securely seated in their sockets.
The Relay retainer plate installed on the relay PCA covers the lower right mounting screw
of the relay PCA. Therefore, when removing the relay PCA, the retainer plate must be
removed first.
