5 Diagnostics and troubleshooting
5.1 General
This section contains troubleshooting for the PGC5000 Master Controller and attached ovens. The analyzer is equipped with
visual indicators allowing the user quick identification and issue resolution.
5.1.1 Power-on self-test
On power up, the main duties of Power-on Self-Test (POST) are handled by the BIOS, which may hand some of these duties to
other programs designed to initialize very specific peripheral devices, notably for video and CANBus initialization.
The POST process tests the basic integrity of the analyzer’s boards during every startup cycle. The POST Failure indicator is
triggered if any of the process tests fail.
If the analyzer triggers the POST Failure indicator, reboot the Master Controller and watch the Local User Interface (LUI) display
screen for “Red” text. The “Red” text reveals the board subsystem having the initialization problem.
5.1.2 Indicator boxes and hex codes
Some functions have associated indicator boxes (diagnostic displays) and hexadecimal (Hex) codes displayed on the Setup
Tab>Status sub-tab (see Figure 5.1, which shows the DTC1 screen). The indicator boxes, when filled (black), indicate the named
action. The hex codes represent error codes. When submitting an issue to ABB support, always include a screen capture, or
record and include the filled indicator boxes and hex codes shown on the display. Include with your report all screens that
apply (i.e., Oven, EPC DTC, and zones).
