The speed exchanger on the BD35 and BD50
Danfoss compressors BD35 and BD50 can work at different velocity because of the speed-
exchanger applied to the electronic unit of the group.
In order to change the velocity of the compressor it is enough to connect one of the cables
EN
of the thermostat to the terminal marked with the letter C and other cable to the terminal T
that corresponds to the velocity that you desire (Picture1).
The picture1 reproduces all the electrical connections. The velocity on the speed-exchanger
is indicated by revolutions per minute (RPM).
Realising the connection between the two terminals C and I present in the picture labelled
with LOW-LEVEL you put the voltage of battery that it is inferior to the standard; The values
of the threshold are reproduced in the Table1 below.
For the selection of the right velocity please refer to the indication on the Table2.
