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.
