8. Fault finding
8.1 Warnings
The pump controller supplies a warning when a problem is encountered. Once the
problem that caused a warning has been corrected, the warning is cleared by the pump
controller.
8.1.1 LED warning indicators
If the problem occurs in the pump, warnings are indicated on the LEDs on the front
control panel, the rear panel and on the PDT if installed.
The warning LEDs on the front control panel and rear panel illuminate continuously
when a warning is supplied.
If a PDT is installed, the warning LED flashes to indicate a new warning. Refer to
PDT
warnings on page 68 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.
8.1.2 PDT warnings
If a PDT is installed, each warning causes a warning message to be displayed. Refer to
Warning and alarm display and acknowledgement on page 51 for more information on
how warnings are handled by the PDT.
Table: Warnings lists the warning messages that can be displayed on the PDT with
possible causes and actions which should be taken.
