Setting the Sequencing Rate
This is only available for CNG Dispensers.
Needs appropriate software.
The rate of sequencing between pressure banks for the CNG dispensers is
done on a percentage basis. There are three percentage settings to choose
from:
Fast, 'FAS' switching to the next higher-pressure bank occurs at 45% of the
full flow rate.
Normal, 'nOr' switching to the next higher-pressure bank occurs at 35% of
the full flow rate.
Slow, 'SLO' switching to the next higher-pressure bank occurs at 25% of
the full flow rate.
To set the Sequencing rate
Press and release the Parameter switch seventeen (17) or more times,
without holding it depressed for long enough to change any digits, until
'SE9','XXX' appears. Hold the switch depressed until the correct
sequencing rate is displayed, then release.
The displayed sequencing rate is now selected and operation of the
dispenser will be affected immediately. The displays will reset after a ten
(10) second timeout.
Validating/Invalidating Cards Pins or Keys
This is only available on Comcard Basic, Compin Basic, or CWIDKey Basic
systems (i.e. 'b' setting digit 3 = 2.
1. Ensure that the nozzle is hung up. Press the Parameter switch 16 or
more times without holding the switch depressed long enough for any
digits to change or for the system to enter the pump number setting
mode. The switch must be depressed for two seconds or longer for the
latter to occur. Card status information will then appear on the litre
display panel. The left of the display panel shows a 'Y' or 'n' where 'Y'
is Valid & 'n' is Invalid; the right of the panel shows the two-digit card,
pin, or key number.
2. The desired card/pin/key number can be selected by changing each
digit using the usual press/hold/release method with the Parameter
switch. When the figure on the left side of the display panel is selected,
it can be changed from 'n' to 'Y' to 'n' etc. by holding the Parameter
switch depressed. Therefore, the respective card status can be
selected by releasing the switch when the desired card status symbol is
displayed.
To change multiple cards repeat the above process for the appropriate card
numbers. The display will return to normal operation after the Parameter
switch is not operated for ten (10) seconds.
On older systems Card 99 is the Service card and was
universally accepted by all Comcard card-readers.
