System failure error list for RC, TC, MC models
System failure error list for RS, TS, MS models

 

 

For RC, TC, MC models 

Failure
 Number
Failure Reason Description
E501 Wire signal off reading is higher than wire signal on reading  
E502 wire reading indicates calibration failed because either the signal off amplitude readings or the signal on amplitude readings exceed their tolerance  
E503 wire reading indicates calibration failed because we detect that robot is not inside the garden during the calibration with signal on   
E504 wire reading indicates calibration failed because we detect that in/out readings are invalid  
E505 Front wheel dropoff lifted reading is equal or smaller than Front wheel dropoff idle reading  
E506 Difference between Front wheel dropoff lifted reading and Front wheel dropoff idle reading is too small.  
E507 front wheel odometer reading is not in tolerance  
E509 Bad battery voltage calibration battery temperature reading indicates that the supplied cells voltages of the calibration setup are not valid
E510 Bad battery voltage calibration battery cells voltage readings exceed the tolerance
E511 battery cells connector is disconnected  
E512 Mow configuration invalid  
E513 Mow thermistor disconnected  
E515 Mow motor is disconnected Motor disconnection is detected when mow pwm is maximal and mow odometer is showing motor is not moving. We will stop when this state is detected for more than 15 seconds.
E516 Drive configuration label is not set  
E517 Drive motor is disconnected Motor disconnection is detected when drive pwm is maximal and drive odometer is showing motor is not moving. We will stop when this state is detected for more than 15 seconds.
E518 tilt calibration failed  
E519 tilt calibration failed because accelerometer readings are not in tolerance  
E520 system configuration is invalid  
E521 STOP button is disconnected in UI panel connector   
E522 Drive configuration is invalid one of the following:
1) left or right drive configuration is unknown
2) left and right drive configurations are different
E523 Safety Standard power up test failed

Failure Reason Description
201 Wire signal off reading is higher than wire signal on reading  
202 wire reading indicates calibration failed because either the signal off amplitude readings or the signal on amplitude readings exceed their tolerance  
203 wire reading indicates calibration failed because we detect that robot is not inside the garden during the calibration with signal on   
204 wire reading indicates calibration failed because we detect that in/out readings are invalid  
205 Front wheel dropoff lifted reading is equal or smaller than Front wheel dropoff idle reading  
206 Difference between Front wheel dropoff lifted reading and Front wheel dropoff idle reading is too small.  
207 bumper calibration results are not reasonable  
208 bumper reading range is too small  
209 Bad battery voltage calibration battery temperature reading indicates that the supplied cells voltages of the calibration setup are not valid
210 Bad battery voltage calibration battery cells voltage readings exceed the tolerance
211 battery cells connector is disconnected  
212 Mow configuration invalid  
213 Mow left thermistor disconnected  
214 Mow right thermistor disconnected  
215 left mow motor is disconnected Motor disconnection is detected when mow pwm is maximal and mow odometer is showing motor is not moving. We will stop when this state is detected for more than 15 seconds.
216 Drive configuration label is not set  
217 left drive motor is disconnected Motor disconnection is detected when drive pwm is maximal and drive odometer is showing motor is not moving. We will stop when this state is detected for more than 15 seconds.
218 tilt calibration failed  
219 tilt calibration failed because accelerometer readings are not in tolerance  
220 system configuration is invalid  
221 front wheel odometer reading is not in tolerance  
222 right drive motor is disconnected  
223 right mow motor is disconnected  
224 safety standard power up test failed   
225 accelerometer configuration failed  
226 wire reading indicates calibration failed because the difference between wire max signal threshold and wire amplitude set point is too big  
227 wire reading indicates calibration failed because the wire no signal gain is too small
