Controller: idec izumi fa-2j plc controller
Traction, 6 stop.... copenhagen😊😊
Problem:
In position normal the elevator Burns 2 of the 3
Main fuses on the 3 phases that goes into the
Elevator control room (machine room)
No problems in position Manuel on top of cabin !!!!
I Can drive the elevator up and Down in position slow
Speed .... āthe danish monteur positionā !!!
Fuses Burns only when the High speed relay is activated
( in position ā normalā)
And i have replaced the High speed relay, but the elevator
Keeps on burning fuses

Itās a 2 speed AC motor !!!!!
I took of all cables to the engine ( 2 X 3 phases from the PLC
CONTROLLER and i measured the windings
( between each one of Them both on High speed
Windings and slow speed windings and between Ground
And each phase terminal)......
It looked okay
Just wanted to share back,that the engine Got new
Windings and it runs like a Dream 😊😊👍
