6.6.1 Traction error codes:
Information codes
1 Initial condition not yet satisfied: butterfly not in neutral position and / or belly switch on and / or potentiometer
supply too low (< 7,5V)
2 Butterfly in neutral position (according potentiometer signal or redundant switch signal)
3 Tiller in neutral position (according input signal)
4 Booster function active
5 Butterfly, platform, guardrail and foot signals correspond whether to pedestrian nor ride on mode
6 Butterfly, platform, guardrail and foot signals correspond to pedestrian mode (=WALK)
7 Butterfly, platform, guardrail and foot signals correspond to ride on mode without guardrail (=FLY)
8 Butterfly, platform, guardrail and foot signals correspond to ride on mode with guardrail (=RIDE)
9 Power save on: if all switch inputs released and standstill the power module is deactivated
10 Analog steering angle signal and / or CAN steering angle value exceed threshold (default: 15°)
11 Speed reduction commanded by input X1:29 (reduction active when input connected to GND)
12 Speed reduction commanded by input X1:57 (reduction active when input connected to GND)
15 Speed reduction commanded by battery interlock at input X1:12 (reduction active when input connected to GND)
19 No speed signal though torque applied
reasons may be: speed sensor problem, motor / wheel / truck blocked
20 Belly function activated by platform, tiller and belly switches
In trucks without platform: Belly function activated by tiller and belly switches
21 Belly function active, reset not yet performed (for reset turn butterfly into neutral position)
27 Truck immobilization due to simultaneous activation of creep function forwards and / or creep function backwards
and / or turning butterfly out of neutral position
28 Creep function backwards active (inputs X1:28 and X1:52 connected to GND)
29 Creep function forwards active (inputs X1:05 and X1:06 connected to GND)
30 Monitoring of rotor field according motor model
35 Battery voltage too low (< 12V)
40 High MOS temperature (> +95°C AND < +200°C)
45 High motor temperature (> +160°C AND < +200°C)
60 Truck immobilization because ok status signal from LES (X1:35) not set
61 Speed reduction requested from LES via CAN
70 Discharging of power module capacitors for test purposes is being performed
71 Switching on of main contactor contact could not be performed
80 [2] The Forks are down (Truck N20)
81 [2] The load is over 1 ton (Truck N20/4W)
82 [2] Creep Speed Buttons are active
83 [3] The Forks are over 1.5m
90 Teaching procedures have not been performed yet
91* Incorrect truck identification from traction controller
92* Incorrect CAN truck identification from steering controller LES
93* Incorrect truck identification from lift controller
Warning codes
110 Brake actuator failure (measured current rise when actuator switched on does not match with correct/ideal
current rise)
