M400E Ozone Analyzer Operator’s Manual Theory of Operation
11.3.6. AC POWER CONFIGURATION
The M400E 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 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.
However, some of the analyzer’s non-digital components, such as the pump and the AC powered
heater for the optional metal wool scrubber (OPT-68) 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.
