AA WRONG SET BATTERY
Condition for error detection
When the key is turned ON, the logic unit checks the battery voltage and compares it with the “SET BAT-
TERY” parameter setting. If the actual value is 20% higher or lower than the nominal value, there is a
fault.
• Check on the Zapi console if the parameter SET BATTERY TYPE (ADJUSTMENT MENU) is set to
24V
• Check the status of the battery and if necessary replace it with a correct one.
AB HI SIDEDRIVER KO
Condition for error detection
The driver which supply the valves coils positive is shorted or open.
Problem in the hardware circuit.
• Check the wiring harnesses and connections on the MHYRIO and solenoid valve sides
• Check the coil status
• Replace the logic unit.

AC EVPG1 DRIVER KO
Condition for error detection
It is referred to the lifting valves EV2 and EVP1.
Check:
• Wiring harness continuity
• Presence of false contacts on connectors on the MHYRIO and solenoid valve sides
• State of coil EV2 (standard 27 ohm) and EVP1 (standard 18 ohm)
• Replace the logic unit.
