13.7.1. AC POWER CONFIGURATION

The 9110T analyzer’s digital components 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,. Internally, the status LEDs located on the Relay PCA, Motherboard and CPU should turn on as soon as the power is supplied.

However, some of the analyzer’s non-digital components, such as the various internal pump options or the AC powered heaters for the NO2  NO converter the reaction cell and some of the 9110T’s must be properly configured for the type of power being supplied to the instrument.

Configuration of the power circuits is set using several jumper sets located on the instruments relay PCA.
