Error F01, F02 and/or F03, motor protection circuit has been triggered due to too high power
consumption from hydraulic motor. The motor is halted for 30sec. When 30sec has timed out,
the motor can be run again and the error message goes off by pressing button <LIFT>.
F04: Phase sequence.
A Phase failure or wrong phase sequence has been detected. The Leveller is halted until the
power supply has been switched off and the error is corrected.
F05: Fault feedback V1.
A fault feedback of solenoid valve V1 has been detected. The error is considered as a fatal error
and the entire system will be halted until the power supply has been switched off and error is
corrected.
F06: Fault feedback V2.
A fault feedback of solenoid valve V2 has been detected. The error is considered as a fatal error
and the entire system will be halted until the power supply has been switched off and error is
corrected.
F07: Fault V1 missing.
Solenoid valve V1 is missing. The Leveller is halted until the power supply has been switched
off and the error is corrected.
F08: Fault V2 missing.
Solenoid valve V2 is missing. The Leveller is halted until the power supply has been switched
off and the error is corrected.
F09: Fault RAM test.
An error in the RAM memory area on the Leveller board has been detected. The error is
considered as a fatal error and the entire system will be halted until the power supply has been
switched off.
F10: Fault flash test.
An error in the Flash and/or register memory area on the Leveller board has been detected. The
error is considered as a fatal error and the entire system will be halted until the power supply
has been switched off.
F11: Fault Push buttons.
An error on the internal push button panel has been detected. The error is considered as a fatal
error and the entire system will be halted until the power supply has been switched off and error
is corrected.
F12: Fault motor current detection.
Motor current to the hydraulic motor has been detected by the motor protection circuit. The
error is considered as a fatal error and the entire system will be halted until the power supply
has been switched off, error is corrected and 30 sec. has passed.
F13: Fault 24 V control voltage.
The 24VDC Control voltage is below -15% and is considered to be too low. The Leveller is
halted until the power supply has been switched off and the error is corrected.
F14: Feedback signal contactor.
A feedback signal error from contactor relays for the hydraulic motor has been detected. The
error is considered as a fatal error and the entire system will be halted until the power supply
has been switched off and error is corrected.
