8.1 General Troubleshooting
Source
Inspection Points
Shore Power
Power outlet, fuse breaker, cables,
connectors.
Inverter
Switches, fuse breaker, inverter type. Confirm inverter power switch is ON. Some vehicles have switches in both the front and rear of the vehicle.
Ferno ICS
Power ON, charger, cables, contacts.
8.2 Status Indicators
Color-coded status indicators alert the operator to safety or functional issues. There priority levels
are: no priority, low, medium, and high. High-priority codes are red; all others are yellow. If a safety
issue occurs, a warning triangle is displayed next to the error code. For service, see "Parts and
Service" on page 46.

8 - TROUBLESHOOTING
Checkpoints
Confirm shore line provides proper voltage power. Re-set any tripped fuse breakers. Confirm cables and
connectors are in good working condition and power is ON.
Re-set any tripped fuse breakers. Confirm inverter has automatic switching between shore and vehicle power.
Confirm power to the charger is ON/powered. Inspect the charger for error status (unplug and plug in again to
re-set). Check wiring for damage and connectors for secure fit. Check metal ICS contacts on fastening system
and cot for corrosion or misalignment.
Solution
1) Release the button(s).
2) Use non-powered operation to complete the transport.
2) Possible stuck button. Disconnect top or bottom button set to locate fault and replace.
3) Possible wiring issue. Continue Troubleshooting.
1) Using caution, clear the leg obstruction or redistribute the weight.
2) Use additional help to provide lift-assistance, or use direct power.
1) Possible battery fault. Swap for a different battery.
2) Check the ICS for power; check contacts are clean.
3) Charge battery on a wall charger (not through ICS). Check if problem is corrected.
Verify the connections between the cot, ICS, and ambulance power supply. The ICS or
charger may be plugged into an outlet providing an incorrect power voltage.
1) Swap for a different battery or use non-powered operation to complete the transport.
2) Allow time for the battery to cool.
1) Use non-powered operation to complete the transport.
2) Allow time for the motors to cool. Check wiring for damage.
Re-connect the cable(s); check wiring for damage.
1) Using caution, clear the leg obstruction or redistribute the weight.
2) Use additional help to provide lift-assistance, or use direct power.
3) Lubricate the slider rails. See "Lubricating the Cot" on page 38.
1) Use direct power to complete the patient transport.
2) Inspect all wiring between the control box, display, and actuators, including wires that
are routed along the main frame.
