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 ca-
bling 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 pos-
sible to measure ohms for the field winding us-
ing a standard universal instrument, since the
winding has a value as low as 0.3 ohm.
