Valid from serial number 723984-
T-code 497
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 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.
