Troubleshooting table (CAN-bus error)
Code Fault/Possible cause solution/action
-
– –
CAN 1: No error
CAN 2: No error
No action.
01
CAN 1: No power
Check the respective setting in the
user interface
02
CAN 1: Voltage fault
Maximum current above the maximum level
(>4A during > 2.5 seconds)
Too many Velos devices (V-packs) connected.
Check wiring, connections and
connected devices
(e.g. for corrosion)
03
CAN 1: Fuse failure
● >7 A during >400 msec
● >15 A during >25 msec
Overloading or short circuit.
Check wiring, connections and
connected devices
04

08
CAN 2: Voltage fault
This error code is followed by code 13, 14, 15 and/or
16
See error code: 13, 14, 15 / 16.
09
CAN 1: Voltage fault (Vout < 15 Vdc)
Output voltage below the minimum value
● Power supply too weak
● Connecting cable too thin (< 1,5mm²)
● Connection cable too long
● Stronger power supply
● Replace the cable (≥ 2 mm² / 15
AWG)
● Shorten the connection cable
10
CAN 1: Voltage fault (Vout > 30 Vdc)
Output voltage above maximum value
● Power supply unit defective
● Incorrect power supply unit
Replace the power supply unit.
11
CAN 1: Voltage fault (Vin < 20 Vdc)
Input voltage below the minimum value
● See error code 09
See error code 09
