Pro-160 / 360 Fault Codes

The Pro-160 and Pro-360 have a number of warning messages or error codes that can appear depending on what the controller thinks is happening.

This table lists;

  • the code
  • any associated sound signal
  • whether the code is a warning or indicates a fault
  • the text shown on the display
  • the behaviour of the controller

 Error Description (Manual) Behaviour
B1 None F Under Voltage The battery voltage is below the Low Voltage cut-off (if set) or 11V (system default). Start-up – Do not start

Run-time – Ramp down, resume if cleared
B2 One short beep (if on in profile) W Low Battery The battery voltage is at or below the low voltage alert (if set) or 11.9 (system default) Depends on profile setting (volt_alert.action)
B3 None W High Battery The battery voltage is above:

60V (Std PRO-160)

90V (HV PRO-160)

 Flash warning message
B4 None F Over Voltage The battery voltage is above:

63V (Std PRO-160)

95V (HV PRO-160)

 Start-up – Do not start

Run-time – Ramp down, resume if cleared
T1 One long beep W High Temp The controller temperature is over 65C Flash warning message

Run-time – ramp down to 50% of max speed (if over 50%)
T2 One long beep F Over Temp The controller temperature is over 75C Start-up – Do not start

Run-time – Ramp down, stop
T3 One long beep W TX High Temp The second thermistor temperature is over warning limit [may be used for motor for example] Flash warning message

 
T4 One long beep W TY High Temp The third thermistor temperature is over warning limit [may be used for battery for example] Flash warning message

 
P1 Continuous F High Pot Lock High POT lockout Start -up -Flash error message until POT is set to minimum

Run-time -N/A
P2 Continuous F Pot Fault [V3 boards]

Pot track fault

The pot top value is higher than the expected value indicating pot wiring fault. See note 1 at end.

 Start-up – Flash error message and switch off

Run-time – Ramp down, stop
P3 Continuous F Pot Fault [V3 boards]

Pot wiper fault

The POT value is higher than the expected range indicating faulty Pot.

 Start-up – Flash error message and switch off

Run-time – Ramp down, stop
P4 3 short F RC Fault RC signal is not in expected range of values Start-up – Flash error message until signal is in range.

Run-time – Ramp down

Restart automatically if ranges return to normal
X1 2 short F Dead Mans Hdl The Dead Man’s handle is set on Start-up – Flash error message until set off

Run-time  – Ramp down

Restart automatically if DMH goes off
X2 2 short F Emerg Stop Emergency stop signal received Start-up – Flash error message until set off

Run-time  – STOP IMMEDIATELY
C1 None W Over Current Current overload occurring. The current is above the SYSTEM (hardcoded) maximum safe curent.

[Note: whether it is + or – overcurrent is not information required by the user]

 Flash warning message. Special behaviour, emergency stop after 300 milliseconds at this level.
C2 None W Current Limit Current limit. Current is being held to the current limit set for the profile Flash warning message.
K1 2 long F Park Brake Parking brake over current Start-up – Do not start

Run-time – Ramp down, stop
Q1-4 3 long F MOSFET Mosfet Faults. See note 2 at end. Start up check
S1 None W Speed Limit Speed limit. Speed (width of signal from speed sensor) is being held to the speed limit set for the profile Flash warning message.
S2 None W Speed Signal Reading from the speed sensor is not in the expected range of values Flash warning message

Notes:

1. P2 Pot fault can also occur if R111 [0 ohms] is blown. This can occur if pin F is short circuited to B+. It can be repaired by bridging with a small wire link.

2. Qx faults can occur if there is a short circuit between mosfets and the heatsink. Check that all insulating washers are in place.
