[123moez]

I am Moez from Tunisia; I get one second hand Mitsui Seiki VS3A. for transportation,
the machine was disassembled and the coolant tank wiring was moved.
When reassembling I could not find all the wiring.

Flood Coolant System one wire BY16 was alone. please can you help me to know with which wire shall I assemble the BY 16 wire?
I let the wire not assembled and turn on the machine, but the machine does not start. One message in the screen ”consult Mitsui seiki service” appear.
please can you help.
Thank you.
