Note 2:
ICON always begins with identification of attached system components (cameras, tracks, etc.).
If vehicle power is turned on after ICON is started, the system will not function until ICON is closed and
restarted.
Ground Fault Detection & Alarms
The front of the high voltage power supply includes power on and off buttons as well as status indicators.
The ON button and status indicators will light green during normal operation. The two red fault indicators
may light momentarily during startup and shut down; this is normal.
There are two status indicators:
1.
Supply:
This is the main power supply providing 400 VDC to the tether. A
SUPPLY
fault
warning will trigger if the AC power input drops below 85 VAC or if the power supply reaches
over-temperature levels. The power supply will be automatically shut down.
2.
Tether:
The power supply is also equipped with fault detection which monitors potential current
leakage from the high voltage power feed to the tether and vehicle. A
TETHER
fault warning may
indicate possible damage to the tether cable or water leakage inside the harness block or
Minitracs™. This fault will also be triggered if the output fuse has blown due to a short circuit.
Tether faults should not be triggered under normal operation and may be an indication of a major device
malfunction or a potential safety hazard. If a tether fault is announced, the power supply should be
disconnected and the reel, deck cable, tether, and vehicle harness whips should be inspected for
damage.
If all cabling looks good, the Minitracs™ and integrated harness block should be examined.
If either of the fault indicators trip, the power supply will automatically disable power to the tether and
vehicle. The corresponding status indicator will light red and the
ON
button will flash to indicate external
power has been disabled. The power supply will not re-enable vehicle power until it has been reset by
pushing the
OFF
button.
WARNING:
A ground fault alarm may be an indication of a safety risk. The
system should be turned off and carefully examined before powering back up.
Note:
The GFI fault detector monitors the high voltage DC power feed only and is not a
replacement for a proper GFCI protected AC power outlet.
