PGC5000
PGC5000 Series Service Instructions
4. Purge, atmospheric vents plugged. Inspect and clear vents.
5. Tubing to and from pressure switches leaking or disconnected. Inspect and replace if necessary.
6. Purge orifice is obstructed. Remove obstruction.
5.6.12 Flame out led on (flame will not ignite)
Flame Out LED on and continued attempts to light the flame have failed..
Causes:
1. Insufficient burner fuel and/or air. Check flows.
2. Plugged vent line. Check cell vent for restriction. Possible plugged breather assembly.
3. Defective igniter.
a. Measure resistance of the igniter at TB16 pins 3 and 4; it should be less than one ohm. Replace as necessary.
b. Measure voltage at TB16 pins 3 and 4 with igniter turned on; 2.0 VAC indicates an open igniter, 1.5 to 1.6 VAC
indicates a good igniter.
c. 0 VAC indicates an electrometer problem or the electrometer is not receiving the ignite signal from the A/D board.
4. Incorrect flame out indication. Measure thermocouple voltage at TB16 pins 1 and 2 on the electrometer PCB. With the
flame lit the reading should be greater than 2.5 mv.
a. If the voltage is greater than 2.5 mv the electrometer is defective.
b. If the voltage is less than 2.5 mv check flows and correct as necessary.
c. Inspect thermocouple for damage and replace as necessary.
d. Inspect jet tip for corrosion and restriction, and replace as necessary.

5.7 Software

A software repair can be as simple as restarting the system or may require performing a System Recovery from files created and
saved on a USB flash drive. In the unlikely event a system recovery is needed, it is easy to do so using a recovery image created
from the Local User Interface using the Setup Tab. The USB flash drive created contains a System Recovery image including all
the software files originally installed on your analyzer at the factory and changes made prior to the last backup.
It is important that you perform the system restore in the order described in this document.
5.7.1 System backup, restore and recovery
From the Setup tab the PGC5000 has several recovery options available (see Figure 5.9). The options allow restore point
creation and/or chromatogram data file copy or deletion

Before starting any maintenance it is recommended that you create a restore point in the system local memory using the USER
Action icon as a precautionary measure.
