Section Four: Over - Current Fault Troubleshooting
This section of the guide is to assist installers, operators, and other personnel on properly troubleshooting VP1000-5
over-current fault conditions. The root causes typically include a blockage in the vapor path and debris / damage to the
rotor / vanes. When the VP1000-5 is operating at a low speed, a high vacuum level typically indicates an issue with the
cover assembly, while a low vacuum level typically indicates a locked rotor due to damage / debris present in the rotor
cavity or the presence of a fluid blockage due to a breach in the product and vapor paths. A breach can be confirmed by
the presence of meter creep on the dispenser totalizer.
No
Verify the performance of the VP1000-5
per B-5 of the A/B sheet (Refer to
Appendix B).
Is the
vacuum level produced
by the VP1000-5 between
60-90” WC?
Disconnect the white reset plug on the MC100-1.
Remove the VP1000-5 front cover to evaluate the rotor/vanes for wear
and/or damage. Refer to Appendix C. Check for debris and/or damage
to the cover assembly and confirm that the VP1000-5 shaft can turn
freely by hand.

Retest
Contact FFS Technical Support for
further assistance.
Install a 0-100" WC vacuum gauge at
the test tee.
Is the
VP1000-5 running at
low or high speed when neither
side of the dispenser is authorized
and the ambient temperature
is above 40ºF?
Check for a leaking input voltage. Refer to Appendices E and F. Yes
No
Review Maintenance Log and ISD
Warning/Failure alarms for recent activity.
To ensure accurate testing results, service personnel
must control both sides of the dispenser by using cones
and/or a service vehicle to block the entire dispenser.
Remove the vacuum gauge from the test tee, re-insert the plug in the
tee, and confirm the ball valve prior to the VP1000-5 inlet is open.
