Appendix A3
A3.2 Warnings
The pump controller generates a warning when a problem is encountered.
By default, the GXS pump is prevented from going on-process when there are active warnings so it is important to
investigate the cause of a warning. It is possible to configure the pump so that it will go on-process with active
warnings - refer to A2.6.7 for more information.
Once the problem that caused a warning has been resolved, the warning is cleared by the pump controller.
A3.2.1 LED warning indicators
If the pump encounters a problem, warnings are indicated on the LEDs on the front control panel, the rear panel and
on the PDT if fitted.
The warning LEDs on the front control panel and rear panel illuminate continuously when a warning is generated.
If a PDT is fitted, the warning LED flashes to indicate a new warning. Refer to Appendix A2.3 for more information
on how warnings are indicated and how they can be acknowledged using the PDT.
Once all the warnings are cleared, the warning LEDs extinguish.
A3.2.2 PDT warnings
If a PDT is fitted, each warning triggers a warning message to be displayed. Refer to Appendix A2.3 for more
information on how warnings are handled by the PDT.
Table A29 lists the warning messages that might be displayed on the PDT with possible causes and actions that should
be taken.
