300
not active in [1] and [2]
Truck without belly function, but belly - switch signal is active
(X1:14 > 16V)
305
not active in [1] and [2]
Truck without platform, but foot - switch signal is active
(X1:8 < 1V)
306
not active in [1] and [2]
Truck without platform, but platform - switch signal is active
(X1:31 < 1V)
307
not active in [1] and [2]
Truck without platform, but guardrail - switch signal is active
(X1:53 < 1V)
310
not active in [1] and [2]
Truck without mast, but signal of mast - switch at 1,5 m is active
(X1:41 < 2,5V)
311
not active in [1], [2] and [3]
Truck without mast, mast potentiometer signal is active (X1:19 > 0,5V)
315
not active in [1], [2] and [3]
Mast potentiometer signal out of tolerated range: X1:19 < 0,5V
reasons may be: wire cut or shortcut to GND
316
not active in [1], [2] and [3]
Mast potentiometer signal out of tolerated range: X1:19 > 9,5V
reason may be: shortcut to supply voltage
6.6.3
Main steering error codes:
Information codes
1
Power-Up -Tests not finished
3
Controller set to Passivemode by CAN-Flasher
7
Unteached Potentiometer or corrupped EEProm
8
incorrect EEProm truckidentifer value
9
incorrect CAN traction truckidentifer
10
Message from Powerpart (pwm to motor voltage fault, but not critical),
monitors set steering value from logic part to current steering value at steering motor
11
Setpotentiometer to actpotentiometer value difference
Warning codes
no error implemented
Error codes
220
no Productiontest (--OK--sign missing in EEPROM)
223
Safetyrelay closed without demand
224
Safetyrelay open but should be closed
225
ext. Safetyrelay closed without demand
226
ext. Safetyrelay open but should be closed
227
Contactor closed without demand
228
Contactor open but should be closed
240
Fatal plant behaviour error: Steering angle varies in the opposite direction to the commanded one (PWM). One
of those components does not work properly: PWM unit, inverter, motor, gear or angle sensor or the steering
axle is externally actively moved (should not occur normally)
244
Error from internal communication between controllers (SSC Watchdog)
250
Errorsignal from Powerpart (1 time occured),
Internal error of powerpart logic chip due to following reasons: undervoltage, high current by short cut,
overtemperature
Note: LES tries to reset the powerpart chip up to three times to keep steering alive
251
Error from Powerpart (3 times errorsignal -> powerpart disabled),
see description of error 250
252
Error from Powerpart (capacitor voltage < Ubattery - 4V),
Measured capacitor voltage for steeringmotor reaches lower limit
254
Error from Powerpart (pwm to motor voltage fault),
Measured motor voltage does match to applied PWM duty cycle ratio and measured battery voltage whereas
motor voltage and current are not both equal to zero (relay contact closed). One of those components does not
work properly: PWM unit, inverter, voltage or current measurement.
255
Error from Powerpart (motorcurrent overrides limit),
Current sensor, motor voltage and steering angle signal courses do not suit to plant model. One of those signals
is erroneous - presumably current signal if no further trouble code generated. The aim of this monitoring function
is the detection of erroneous current signal.
