Why does my Hyster R1.6 Forklifts 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 should I do if my Hyster R1.6 shows “Contactor open”?
If your Hyster Forklifts displays “Contactor open”, it means that the main contactor coil has been activated by the control device, but the contactor fails to close. It could be a problem with the contacts in the MC not working (not inserted), try replacing the MC. If the MC contactors work properly, the problem lies within the control device, so replace it.
What does it mean when my Hyster R1.6 Forklifts displays “Vacc not ok”?
If your Hyster Forklifts shows “Vacc not ok”, it means that the ACCELERATOR reading in the TESTER menu is 1.0V over the min. PROGRAM VACC acquisition when the throttle is released. Acquire the maximum and minimum value of the potentiometer via the PROGRAM VACC function. If the alarm persists, check the mechanical calibration and the operation of the potentiometer. If the alarm is not deactivated, the fault is in the ACE logic board, therefore proceed with replacement.
How do I fix “Th. protection” error on my Hyster R1.6 Forklifts?
If your Hyster Forklifts displays “Th. protection”, it means the base plate temperature is above 85°C. Increase the cooling of the control device. Ensure adequate cooling by checking the fol w [m3/h] and temperature [°C] of the cooling air, especially if using a finned heat dissipation device.
What causes the “Vmn low” error on my Hyster Forklifts?
If your Hyster Forklifts displays “Vmn low”, it can be due to a test on start-up or a motor operating test. If the problem appears on start up (LC doesn't close at all), check the internal motor connections (ohm continuity), the motor power cable connections and motor loss to the truck frame. If the motor connections are OK, the problem lies within the control device, so replace it.
What does “Vmn high” mean on my Hyster R1.6?
If your Hyster Forklifts displays “Vmn high”, it can be due to a test before switching on the LC or once the start-up diagnosis has been passed. If the problem appears on start up (LC doesn't close at all), check the internal motor connections (ohm continuity), the motor power cable connections. If the motor connections are OK, the problem lies within the control device, so replace it.
How to troubleshoot “Motor temperat.” warning on Hyster R1.6 Forklifts?
If your Hyster Forklifts displays “Motor temperat.”, it means the temperature sensor is open (if digital) or it has exceeded the 150°C threshold (if analog). Check the heat sensor inside the motor (look for MOTOR TEMPERATURE in the TESTER menu); check the value in ohms of the sensor and the sensor cabling. If the sensor is OK, boost the motor cooling.
What does “Logic failure #3” mean on Hyster Forklifts?
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.
What does “Capacitor charge” mean on my Hyster R1.6 Forklifts?
If your Hyster Forklifts displays “Capacitor charge” alarm, it indicates that when the key is turned on, the inverter tries to charge the power capacitors but the measured capacitor voltage is less than 20% of the nominal voltage of the battery. Check for an external load in parallel with the bank of capacitors, add a power resistance over the electrical terminals of the line contactor, or consider that the charging circuit is faulty inside the control device or there is a problem in the electrical section of the control device.
