MODEL GFC7000EU CO ANALYZER WITH AUTO-REFERENCE
(Addendum to GFC7000E Manual PN 04584)
05134 Rev -
2
OVERVIEW
The model GFC7000EU is a close derivative of the Model GFC7000E CO Analyzer.
The optical bench is longer (14 m), making the instrument more sensitive at low CO2
levels. The instrument has a user selectable full scale range of 0-100 PPB to 0-100 PPM
of CO2.
The instrument does not come equipped with a sample flow rate sensor. Hence, disregard
any reference to the flow sensor in the users manual.
Because the GFC7000EU is a close derivative of GFC7000E, the Model GFC7000E
Instruction Manual continues to be valid as the reference manual covering the details of
the instrument’s components. Only the sections of the manual that are different between
the GFC7000E and a GFC7000EU are listed in this addendum.

3.1.2. Pneumatic Connections
This section is similar to the one in the manual, with the following exception. The
extra port labeled “From Purge” is the exhaust port for the for the purge gas. The
gas needs to exhausted with a gas line not more than 10 meters long.
In addition, the GFC7000EU uses a different sample pressure sensor than the
GFC7000E. The GFc7000EU pressure sensor is rated for oxygen service. The part
number is listed in the appendix – spare parts.
6.13.1.3 Relay alarm outputs

MODEL GFC7000EU CO ANALYZER WITH AUTO-REFERENCE
(Addendum to GFC7000E Manual PN 04584)

4
There are 4 relay alarm outputs (AL1-AL4) on the rear panel. AL1 is for system
okay, AL2 is for concentration limit 1 exceeded and AL3 is for concentration limit 2
exceeded. The relay alarm output AL1 is enabled all the time, whereas the AL2 and
AL3 can be enabled/disabled by going into the diagnostics menu (with 929
password), then factory options, then turning conc. Alarm Relays ON or OFF. When
the concentration alarm relays are enabled, concentration alarms status is no longer
available through the “Status output” pins. So, either the alarm relays or the status bits
could be used to monitor the concentration alarms but not both at the same time. The
default factory setting is to enable the concentration alarm relays. The AL1 relay is
energized when the system is okay and de-energized when the system has a fault. The
AL2 and AL3 relays energize when the corresponding concentration limits are
exceeded.
11.1.1. Interpreting WARNING Messages
The most common and/or serious instrument failures will result in a warning message
being displayed on the front panel. The table below lists warning messages, along with
their meaning and recommended corrective action.
It should be noted that if more than two or three warning messages occur at the same
time, it is often an indication that some fundamental analyzer sub-system (power supply,
Relay Board, Motherboard) has failed rather than indication of the of the specific failures
referenced by the warnings. In this case, it is recommended that proper operation of
power supplies, the Relay Board, and the A/D Board be confirmed before addressing the
specific warning messages.
The analyzer will alert the user that a Warning Message is active by displaying the
keypad label MSG on the Front Panel. In this case the Front panel display will look
something like the following:
The analyzer will also alert the user via the Serial I/O COM port(s) and cause the FAULT
LED on the Front panel to blink.
