- Check trailer fuses.
Error 620: Command echo
The system did not recognize the last command.
Error 621: Command fault
The system did not accept the last command.
Error 622: System Response
The system response to the last command is not accepted.
- Bad Numeric format.
Error 623: Battery needs charging
Voltage detectors found a too low battery voltage.
- Check alternator and charging circuits.
- Check charging cable connections and fuses.
- Check Over/Under voltage detectors by supplying "battery" power from a
variable (9 to 15V) supply.
NOTE: do not exceed 14.5V for a longer period of time.
Error 624: Battery over-charged
Voltage detectors found a too high battery voltage.
NOTE that battery overvoltage may damage the System.
- Check alternator.
- Check alternator regulator.
- Check Over/Under voltage detectors by supplying "battery" power from a
variable (9 to 15V) supply.
NOTE: do not exceed 14.5V for a longer period of time.
Error 625: 30V OFF RANGE
Voltage detectors found a too low or too high 30V (+/-15V) supply voltage
(less than approx. 28V or greater than approx. 32V).
Possible causes:
Battery voltage off range.
+/-15V power supply defective/short circuited.
- Recharge battery if low. Check alternator regulator if voltage is too high,
which may damage the power supply.
- Monitor the +/-15V in the Information - Voltages window.
Error 626: 5V TOO LOW
Voltage detectors have caught a too low 5V supply voltage
(less than approx. 4.7V).
Possible causes:
Battery voltage Off Range.
5V power supply defective or overloaded/short circuited.
- Recharge battery if low. Check alternator regulator if voltage is too high,
which may have damaged the 5V power supply.
- Monitor the 5V in the Infomation - Voltages window.
Error 627: 5V TOO HIGH
Voltage detectors have caught a too high 5V supply voltage (greater than approx.
5.3V).
NOTE that the digital circuits are specified to operate properly at a max. supply
voltage of 5.3V, and if the supply voltage exceeds 7V, then the digital circuits
may be damaged!
Possible causes:
5V supply defective.
- Monitor the 5V in the Information - Voltages window.
Error 630: Transport lock
1. When Lower Plate is initiated from “Transport Position” (PH activated),
then the PL switch must remain ACTIVATED for at least 2 seconds (typ.).
2. Deactivation of the PH switch must occur prior to PL Deactivation.
If 1 or 2 fails, then the plate will be raised automatically to release the locks.
