Connection
When connecting the Ridder RSU limit switch system, please refer to the wiring diagrams provided for
this purpose.
Setting
The "start position" and "end position" are set as follows:
• By rotating the output shaft (manually or under power), bring the system to the "start position" or
"end position" and determine which duty switch (ES11 or ES12) should be tripped. The switching
sense of the RSU limit switch system can be reversed by swapping connections 1 and 7 in the
connection block.
• Turn the milled bush (2) on the appropriate side, "hand tight" up to the stop (7). The milled bush can
easily be screwed by hand along the threaded shaft (1). The switch follower (4) also moves along
the threaded shaft.
• Now rotate the adjustment ring (3) over the milled nut just far enough to trip the duty switch. Then
fasten the adjustment ring with setscrews (a and b) firmly on the milled nut. The adjustment ring can
no longer be rotated over the milled nut.
• Repeat previous items to adjust the limit switch system for the opposite rotation direction.
This completes the setting of the limit switch system.
Caution
Once an RSU limit switch system has been set and the motor gearbox is operated manually, always
make certain that the limiting positions set by the limit switch are never exceeded. This can seriously
damage the limit switch system, such that the limit switch system no longer functions correctly!
