Possible cause / Hint or Solution
¤¤ ¤ (2+1)
CAPACITOR CHARGE
Capacitors are not charged within 500 ms after Key switch is closed / Check [PTC] resistor circuit. / If above is ok replace transistor regulator.
VMN NOT OK
VMN armature driver problem. Incorrect motor connection s/c in motor windings to chassis. Transistor regulator defect. / Check armature connections [M1] are correct and no internal s/c exists. If above is ok replace transistor regulator.
VFIELD NOT OK
Field Voltage problem. Traction motor’s [M1] field winding s/c or o/c. Field winding incorrectly connected to the transistor regulator. Transistor regulator defect. / Check field connections [M1] are correct and no motor s/c exists. If above is ok replace transistor regulator.
NO FIELD CUR
Field current abnormally low. Traction motor’s [M1] field winding s/c or o/c. Field winding incorrectly connected to the transistor regulator. Transistor regulator defect. / Check field connections [M1] are correct and no motor s/c exists. If above is ok replace transistor regulator.
FW HIGH FIELD CURR.
Field current abnormally high in drive wheel direction. Traction motor´s [M1] field winding s/c or o/c. Field winding incorrectly connected to the transistor regulator. Transistor regulator defect. / Check field connections [M1] are correct and no motor s/c exists. If above is ok replace transistor regulator.
BW HIGH FIELD CURR.
Field current abnormally high in forks direction. Traction motor´s [M1] field winding s/c or o/c. Field winding incorrectly connected to the transistor regulator. Transistor regulator defect. / Check field connections [M1] are correct and no motor s/c exists. If above is ok replace transistor regulator.
STBY I HIGH
Armature current abnormally high whilst in stand-by. Transistor regulator defect. / Replace transistor regulator.
I=0 EVER
Armature current abnormally low whilst driving. / Check armature connections, check or replace carbon brushes.If above is ok replace transistor regulator.
CURR. PROTECTION
Armature current abnormally high whilst driving. / Check armature connections for s/c. If above is ok replace transistor regulator.
