FAQ & Troubleshooting
•
Lost bypass card
o
If the lost bypass card needs to be deactivated for security reasons, the operator will
need to repair all remaining bypass cards. Powering on the monitor while in pairing
mode clears all paired bypass cards. Follow the pairing procedure to pair each active
card. Up to 10 bypass cards total can be paired to the monitor.
•
Monitor output does not change, even though display does.
o
The relays are all protected by fuses located in the enclosure. Disconnect power, open
the enclosure, and verify fuses F1, F2, F3, and F4 are all intact. Refer to the maintenance
section of this manual if any fuses need to be replaced.
o
In extreme cases, a permit relay contact could become welded together. Should this
occur, the system will detect a failure and enter a failsafe mode to prevent further
damage or unsafe operation. Please contact Dixon support if this is the suspected
failure.
•
No lights are showing when powering on the monitor
o
Power off the monitor, then open the enclosure. Check that fuses F18, and F20 are
intact. Refer to maintenance section of this manual if any fuses need to be replaced.
•
ESTOP occurred and monitor appears to be stuck non-permissive
o
A bypass card is necessary to exit failsafe mode. Hold up either the Overfill bypass card
or the Ground/TIM bypass card to the bypass indicator to reset the ESTOP lock.
•
The lid will not open.
o
Once the lid screws are removed the lid should droop slightly and rest on the hinges. If
the hinges have become out of alignment with the lid opening direction, the lid will not
pivot open. To realign the hinges, pull the lid away from the base of the box, then use a
7/16” [12mm] open-end wrench to rotate the hinge until the lid can open.
