MODEL GFC7000EU CO ANALYZER WITH AUTO-REFERENCE

(Addendum to GFC7000E Manual PN 04584)

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:

SAMPLE

RANGE=50.00 PPM

CO = 00.00

<TST TST>

CAL

MSG

CLR SETUP

 

 

 

 

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.
