Remark
:
The micro annular gear pumps mzr-2521, mzr-2921 and mzr-4622 are equipped
by default with a 10-pole motor connector. For the S-KG control unit a 6-pole
motor connector has been used for a more compact design.
In order to allow connection of the micro annular gear pump to the S-KG control
unit, the latter is delivered with an adapter cable.
The following description has for purpose to show you how to operate the
pumps equipped with a 10-pole motor connector without the adapter cable and
with the control unit S-KG.
In order to replace the 10-pole motor connector with a 6-pole one, follow these
steps:
−
Cut off the 10-pole connector at the ribbon cable inlet with a cutter or scissors
−
Place the end of the ribbon cable in the 6-pole connector, adjust its position as
described in the table 21 and press the two parts of the connector tightly
together. During the assembly please pay attention to the correct connector
orientation. The color mark of the ribbon cable must be placed on pin 1.
