11.5.4. AC POWER CONFIGURATION
The E-Series digital electronic systems will operate with any of the specified power regimes. As long as
instrument is connected to 100-120 VAC or 220-240 VAC at either 50 or 60 Hz it will turn on and after about 30
seconds show a front panel display. Internally, the status LEDs located on the Relay PCA, Motherboard and
CPU should turn on as soon as the power is supplied.
On the other hand, some of the analyzer’s non-digital components, such as the pump and the various AC
powered heaters must be properly configured for the type of power being supplied to the instrument. Figure 11-
16shows the location of the various sets of AC Configuration jumpers.

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.
