Warnings

The pump controller generates a warning when a problem is encountered. Once the problem that caused a warning
has been resolved, the warning is cleared by the pump controller.
A2.1.1 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
on how warnings are indicated and how they can be acknowledged using the PDT.
Once all the warnings are cleared, the warning LEDs extinguish.
A2.1.2 PDT warnings
If a PDT is fitted, each warning triggers a warning message to be displayed. Refer to
information on how warnings are handled by the PDT.
Table A15 lists the warning messages that might be displayed on the PDT with possible causes and actions you should
take.
