Code E104
Description Switch-transistor to brake is short-circuited
Possible error
cause
Error in the travel regulator, output. A1/3.
Incorrect value on parameter 22
Action
Check cabling and contacts. Measure Ohms on the
magnet coil (Y1) for the brake. Value 13-15 ohm.
Check parameter 22
Code E106
Description Digital outputs short-circuited or exceeding field
current limit.
Possible error
cause
Problem regulating the field current.
Internal monitoring error.
Action
1. Check the output for main contactor K10 (A1/4),
check cabling and contacts and measure ohms
for the coil. Value 25-30 ohm. Check the output
for the brake coil K10 (A1/3), check cabling and
contacts and measure ohms for the coil. Value
13-15 ohm.
2. Check the output for horn (A1/7), check ca-
bling and contacts.
3. Check the drive motor’s shunt winding and ca-
bling and contacts. Unfortunately it is not possi-
ble to measure ohms for the field winding using a
standard universal instrument, since the winding
has a value as low as 0.3 ohm.
