2.1.1. 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 2-3 shows the location of the various sets of AC Configuration jumpers.
