40 202 BRAKE RUN OUT Brake circuit error This alarm is displayed if the operation of the electric brakes
of the drive motors was forced due to inconsistency between
the drive speed value detected by the encoders and that
required by the command (e.g.: control loss during drive
highly inclined ground).
Turn the system off and on.
Check out the condition of the brakes and in case of
excessive wear, replace them.
40 254 AUX DRIV.SHRT. Possible short circuit on electric
brake output
A) Check if there is a lowering or low impedance between
NEB CNA # 4 and -BATT.
B) The driver circuit is be damaged in the controller, which
must be replaced.
41 251 WRONG BATTERY Wrong battery than that set A) Check that the parameter value SET BATTERY of the
controller matches the rated voltage of the battery.
B) Check that for the parameter TESTER MENU /
BATTERY VOLTAGE the same value of the battery voltage
measured with a voltmeter is displayed. If it does not match,
execute the function "ADJUST BATTERY".
C) Replace the battery.
42 246 AUX DRIV.OPEN Circuit open on output command
of electric brake
Replace the controller.
43 198 OVERLOAD Overload alarm Check that you have not exceeded the allowed load: if you
have, remove the overload and check that the alarm
disappears.
If the alarm persists, open the control panel and make sure
the overload controller board is correctly connected and
powered.
Check out any alarm messages on the display of the
overload controller board.
If necessary, contact AIRO technicians.
44 199 TILT SENSOR Tilt alarm Make sure the ground inclination does not exceed the limits:
if it does, move to a level ground and check if the alarm
disappears.
If the alarm remains active even on level ground, check the
tilt sensor wiring: in case of correct wiring, follow the manual
and on level ground perform a new calibration of the zero of
the tilt sensor;
If the problem still exists, try replacing the tilt sensor.
48 240 EVP DRIVER OPEN Circuit open on proportional
solenoid valve
Please check the EVP coil impedance of the proportional
solenoid.
If the EVP coil impedance is OK, the problem is in the
controller, which must be replaced.
49 241 MANY PUMP REQS Pump speed simultaneous
requests
Only one pump function at a time can be requested.
Bring back all joysticks to rest position and try executing
only one command at a time.
50 215 EVP DRIV. SHORT. Short circuit on proportional
solenoid valve
Check if there is a low impedance or short circuit between
the negative of the coil and -BATT.
If this is not case, the driver circuit may be damaged and the
controller must be replaced.
51 228 TILLER OPEN Dead-man button not pressed At the next command the warning disappears.
52 52 PUMP I=0 EVER Error on pump feedback current A) Check if there is continuity on the motor connection. If the
motor connection is open, the current cannot flow, then the
test fails and the error code is displayed.
B) If everything is ok for what concerns the motor, the
problem might be in the current sensor or in the relevant
circuit.
53 53 STBY I HIGH Feedback current sensor
damaged This type of error is not related to external components, so if
present, replace the controller.
