Turbine Generator Gas Analyzer Installation

Installation
The Model 2750 is a portable unit and can easily be setup close to
the analysis site. To ensure accuracy, however, the analyzer should be
setup in such a manner as to avoid:
 Direct sunlight
 Drafts of air
 Shock and vibration
 Temperatures below 30° F or above 110° F
For best results, the analyzer should be placed as close as possible
to the sample point to minimize the effects of sample line lag time on the
analysis.
An outline diagram, showing the location and identification of the
gas port and electrical connections, as well as the physical dimensions of
the analyzer case, is included in the drawings at the rear of the manual.
Installation is quick and easy and consists of:
 Power and signal output connection
 Connecting the sample or calibration gas
 Allowing the analyzer to warm up.
 Calibrating the instrument.
3.1 Electrical Connections
Power to the instrument is supplied by a 90-264 VAC 47-63 Hz
universal external power adapter. This adapter provides 1.4 Amperes at
9 VDC required by the instrument. The adapter plugs into a port on the
left side of the main panel as shown in Figure 3-1.
A second port, also on the left side of the panel, provides access to
a 0-1 VDC (0.8 – 1 VDC for the H
2
in Air range) output signal for
percent of range monitoring or recording. A connector is supplied for
interfacing to this port. To use this signal, connect a 2-conductor
