There are several changes between the Relay PCA 04523 and previous version regarding AC
power configuration and distribution.
Previously, in analyzer models with internal pumps, the AC power for the pump came
directly from the instrument back panel. The 04523 version handles all AC and DC power
distribution including power to the pump.
Prior to this change, configuring the pump for compatibility with various line voltages and
frequencies was done with a set of hard-wired, in-line connections. The Relay PCA
04523, now includes a set of jumpers that perform this function. This change increase
reliability and simplifies troubleshooting and repair operations.
The Relay PCA 04523, includes a set of jumpers that connect AC power to heaters
included in several optional items, such as the IZS valve option and the O
2
sensor option
available on the M100E, M200E and M400E series instruments. In earlier versions of the
relay PCA this was also handled by in-line connections.
