End of Sale Indicators
The end of sale indicator allows you to determine the reason why the last fill
ended. This can be very useful for fault finding and diagnostics.
Recent versions of CNG software will flash the end of sale indicator in the
price per litre window at the end of each fill during normal operation. Older
versions of software will need to use the procedure below to view the end of
sale indicator.
To view the End of Sale indicators
1. Press and release the Parameter switch until the required hose number
(Pn, PnA or Pnb) is displayed.
2. The number in the unit price display is the end of sale indicator for the
hose number shown.
See the table below for the meaning of the number displayed.
