What does “Pot accel mism” mean on my Hyster R1.4?
If your Hyster Forklifts displays “Pot accel mism”, check the potentiometers. If the potentiometer works properly and the wiring is correct, the ACE-2 logic board needs replacing.
Why does my Hyster R1.4 say “Battery low”?
If your Hyster Forklifts displays “Battery low”, it means the battery charge is less than or equal to 10% of the total charge and the BATTERY CHECK adjustment is not 0. Take the charged battery. If it doesn't work, measure the battery voltage with a voltmeter and compare it to the value in the BATTERY VOLTAGE parameter. If they are different, adjust the value of the ADJUST BATTERY function.
What to do if I see an “Eeprom ko” alarm on my Hyster Forklifts?
If the “Eeprom ko” alarm appears on your Hyster Forklifts, it indicates a hardware or software defect in the integrated non-volatile memory. Try performing a CLEAR EEPROM operation (refer to the console manual). Power cycle the device using the key to check if the alarm disappears. If the alarm persists, the control device needs replacement. If the alarm disappears, the parameters will be replaced by the default ones.
What does “Dir sel out rang” mean on my Hyster Forklifts?
If your Hyster Forklifts displays “Dir sel out rang”, check the connections of the switch and measure the signal with a tester.
What does “Pot brake mism” mean on Hyster R1.4?
If your Hyster Forklifts displays “Pot brake mism”, check the potentiometers. If the potentiometer works properly and the wiring is correct, the ACE-2 logic board needs replacing.
What does “Tiller open” mean on Hyster R1.4 Forklifts?
If your Hyster Forklifts displays “Tiller open”, the warning disappears with the next drive request.
What does “Flash checksum” mean on my Hyster R1.4 Forklifts?
If your Hyster Forklifts displays “Flash checksum”, try reprogramming the logic. If the alarm is still signalled, then the problem is in the microcontroller and you should replace the ACE logic board.
What causes “Tiller mismatch” on Hyster Forklifts?
If your Hyster Forklifts displays “Tiller mismatch”, check the wiring of the Tiller input (use the TESTER items to make troubleshooting easier). If the Tiller switch works properly and the wiring is correct, the ACE-2 logic board needs replacing.
What does “Output mismatch” mean on my Hyster R1.4 Forklifts?
If your Hyster Forklifts displays “Output mismatch”, this is a fault inside the control device and it is necessary to proceed with replacement.
What does “Logic failure #3” mean on Hyster R1.4?
If your Hyster Forklifts displays “Logic failure #3”, it means there is a hardware problem pertaining to the logic card as a protection against high current values (overload). When it manifests itself the ACE logic board needs replacing.
