Product Information WWC T1 Set Up & Maintenance Manual
If the nozzle is replaced with volume = 0 before the time out expires, the leak
sequence counter is neither incremented nor reset i.e. this will not increase the
volume lost if it is a real leak.
If an error is detected, all motors and valves will be switched off and the error
will be logged and displayed with the standard error format:-
p : product
s : side (R/L)
Note : If HOMs are used, HC may be displayed as H1 to H4.
Error Reset Menu
Within the Maintenance menu, the sub-menu AFM-Leak (FLPROT - Flow
Protection menu) needs to be added to display the status of each installed product
per side. For standard dispensers this is related to the hose and for SHS/Satellite
dispensers, it is related to the product.
ON : Hose is activated and ready for use
OFF : Hose is blocked due to leak error (or manually set to OFF)
Note : It is not possible to cover all leak situations and a certain amount of
volume may still be lost.
Fraud Detection
This function is designed to prevent uncontrolled fuel flow by the detection and
control of such situations as far as possible using a limited scope of detection
methods and actions.
Additional sensors on the Nozzle Bus enable the meters/pulsers to detect any
rotations and the calculator will switch off all transactions (where possible) and
log the unexpected flow events. This functionality requires the use of specific
hardware i.e. sensors using the Hall Sensor Controller (HSC).
This function is not available in all installations due to the maximum limit of 32
sensors on the sensor bus. Only existing piston meters will be supported; AFM
will not be supported.
