TROUBLESHOOTING
This section provides troubleshooting recommendations for the BFCV50NPTF Valve and FillSafe Zero
system
when installed, operated and maintained in accordance with Banlaw guidelines.
PROBLEM
PROBABLE CAUSE AND SOLUTION
Premature nozzle
shut-off at the
start
of or
during
the
refuelling.
•
Zero system requires bleeding (to remove air). With the supply pump
running, cycle nozzle T-handle between ON and OFF several times to
resolve this issue (also refer section 5.3).
•
Residual pressure in Pilot line. Cycle nozzle T-handle between ON and OFF
several times to resolve this issue.
•
Pilot line blocked/obstructed, kinked or undersized. Check Pilot line size
and connections for blockages or obstructions. Avoid the use of restricted
bore style fittings, sharp elbows etc. within the Pilot Line routing between
the Flow Control Valve and Level Sensor.
•
Level Sensor installed too high (over 4m (13’)) above the Flow Control
Valve).
•
The BVLS model “venting” Level Sensor is
not installed correctly onto the
tank, e.g. installed within an “extended” socket or riser pipe etc. Refer to
BVLS requirements (i.e. PDS document) and rectify.
•
Float Valve at base of Level Sensor is “stuck” in the closed (up) position.
Remove Level Sensor, investigate, identify root cause and rectify.
•
Faulty Level Sensor. Replace Level Sensor.
•
Fuel flow out of the Flow Control Valve outlet ports is “choked” –
i.e. the
Valve is installed within a pipe, extended socket, etc. or installed too close
to the side of the tank or internal tank baffle (plate). Refer section 5.1.
•
Piston mechanism within Flow Control Valve is “stuck” in the closed
(forward) or otherwise restrict
ed in its “free” reciprocating action.
Remove Valve, investigate, identify root cause and rectify.
•
Faulty Flow Control Valve. Replace Flow Control Valve.
•
Flow rate below recommended minimum. Increase delivery flow rate.
•
Flow rate above recommended maximum. Reduce delivery flow rate.
