Eje 120 Error Code 4372 Work Better | Jungheinrich

: Identify the unique component fault, in this case, the tiller's analog inputs.
This is the practical "work" you asked for. Follow these steps in sequence.
To prevent Error Code 4372 from disrupting your operations in the future, implement these best practices into your routine maintenance schedule:
Moisture and dust entry will distort delicate analog signals.
To return the machine to operation, follow these diagnostic steps in sequence.
If the error code 4372 returns after a power cycle, one of the following interventions will likely be required.
Before you start working on the EJE 120, gather the following:
A: Unlikely. Low hydraulic oil causes slow lifting or noise, not an electrical error code. However, extremely cold, thick oil can cause the motor to work harder, dropping voltage. Check oil level and viscosity (ISO VG 32 or 46).
Older EJE 120 units use a brushed DC lift motor. Worn brushes increase internal resistance. When the controller commands lift, the motor tries to draw current, but the resistance causes a voltage drop that the controller misinterprets as a battery issue.
