Teledyne 4020 - Hydrocarbon analyzer - Manual (Page 19)

Total Hydrocarbon Analyzer Introduction
Teledyne Analytical Instruments 3
The standard analyzer is housed in a sheet steel equipment case
flush-mounted in a 19" rack. The front interface panel is mounted on a
door which, when opened, allows convenient access to the 4020
electronics. The entire front panel can slide out of the chassis to provide
greater access to the electronics and to the sample system. Gas pressure
and flow controls are mounted on the front panel adjacent to the LED
and VFD displays and user interface.
At the rear of the instrument are ports for the introduction of air,
fuel, zero, span, and sample gas. A single 50-pin user-interface cable
connector contains input/output and alarm signals available to the user.
An RS-232 port is also available at the rear panel for connection to a
remote computer or other digital communication device. The Model
4020 is set up for either 120 VAC 60 Hz or 230 50/60 Hz operation
depending on the customer’s requirements. The appropriate power cord
for your unit has been shipped with this instrument.
