Electrical System – 5000 Error codes

CodeE104

DescriptionSwitch-transistor to brake is short-circuited

Possible error cause Error in the travel regulator, output. A1/3. Incorrect value on parameter 22

ActionCheck cabling and contacts. Measure Ohms on the magnet coil (Y1) for the brake. Value 13-15 ohm. Check parameter 22

CodeE106

DescriptionDigital 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 cabling and contacts.

3.Check the drive motor’s shunt winding and cabling and contacts. Unfortunately it is not possible to measure ohms for the field winding using a standard universal instrument, since the winding has a value as low as 0.3 ohm.
