VFIELD NOT OK

Capacitors are not charged within 500 ms after Key switch is closed / Check [PTC] resistor circuit. / If above is ok replace transistor regulator.

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.

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.

¤¤ ¤¤ (2+2) 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.
