4:188 Error on the cabin tilt sen-
sor
The cabin tilt sensors are emitting different values (Ergo
truck).
Tilting up of the cabin pre-
vented.
Check the electrical supply, harness and sensors for cabin
tilting.
4:189 Pressure sensor error The pressure signal is outside the permitted range, 0.3–4.7
V.
4:189 Pressure sensor error The pressure signal is outside the permitted range, 0.3–4.7
V.
The program assumes the
maximum load on the forks
(250 bar)
Check pressure sensor B4, the electrical supply, X130:3
and wiring harness.
4:192 Mast separation sensor
error
The mast separation sensors A and B have a signal combi-
nation that is not permitted.
Lift/lowering speed reduced Check the mast separation sensor signals, X130:39 and
X130:27. They must change at the same time as the mast
is separated and have opposite values.
4:193 Reach movement sensor
error
No pulses from the reach movement length sensor during
reach movement.
Reduced reach movement
speed
1. Check the length sensors' signal X130:38 and X130:11. If
the reach carriage has reached its end position, check
parameter 1265, reach movement length.
2. Recalibrate valve Q6 and Q7.
3. If the reach carriage moves too ponderously, check the
adjustment of the rollers.
4:200 Unexpected error Unknown drive error.
Deactivated hydraulics Check that the same versions of the software are being
used in the MCU and ACH. Update to the latest version.
Report to BT.
4:205 Temperature error Pump motor temperature is over 180 °C.
Deactivated hydraulics 1. Check the motor compartment fan.
2. Check the pump motor and temperature sensor.
3. No fault; may be due to intensive operation.
4:214–
4:216
CAN 2 communication
error
The MCU or ACH have not received a response via CAN in
70 ms.
See 4:205. Check that CAN 2 is intact in terms of wiring harness, final
resistance and contacts. Check that the green LED on the
ACH is on and remains on.
4:220–
4:222
Incorrect DC voltage ACH DC voltage is outside the permitted voltage range.
See 4:205. Check the wiring harness, the fuses F3 and F71, and the
main contactor. Check that the green LED on the ACH is
on.
