Control circuit specifications
2.3.2 Changing the control logic
The input signals are set to sink logic (SINK) when shipped from
the factory.
To change the control logic, the jumper connector above the
control terminal must be moved to the other position.
Change the jumper connector in the sink logic (SINK) position
to source logic (SOURCE) position using tweezers, a pair of
long-nose pliers etc. Change the jumper connector position
before switching power ON.
NOTE
Fully make sure that the front cover has been reinstalled securely.
The capacity plate is placed on the front cover and the rating plate is on the drive unit. Since these plates have the
same serial numbers, always reinstall the removed cover onto the original drive unit.
The sink-source logic change-over jumper connector must be fitted in only one of those positions. If it is fitted in both
positions at the same time, the drive unit may be damaged.
