Starting from the following serial nbrs:

MAR 55 S. N. 01755MAR 75 01247MAR 105 02709MAR 125 01257

the control box has been changed in most of the electric components as well as in itswiring connections.

Moreover, in addition to the electrical components used till now, there are two timedelay relais to:

a Delay the start up of compressor by 18' at every start up of machineb Delay the stop of the drum by 18' at every stop of the machine

as well as a 3-phase monitoring relay on the power in a drum rotation electronic controlboard (it operates using the Hall effect sensor/principle as done on our Flakermachines).

In case the drum is not rotating at all (or it rotates too slow - lees then 1/4 turn every30"), the new electronic control board trips off the entire machine so to avoid that, incase of breakage of the fiber keys, the drive motor/gear reducer and compressor canoperate with the drum off.

Attached you can find a short presentation of the operation of components of the newcontrol box as well as the new wiring diagram.

Starting from November 2005, all the MAR Split as well as the MAR 205-305 will beequipped with this new control box.

The spare list of the MAR 55-75-105-125 control box in Internet will be soon modifiedaccordingly.
