Connecting limit switches
The following limit switches can be connected to the 3RA64/3RA65 compact starter with
IO-Link:
●
3RA64 direct starter: one limit switch
●
3RA65 reversing starter: two limit switches
When the contacts open, the limit switch function immediately shuts down the compact
starter. Direction of rotation 1 is shut down via terminals Y1 - Y2, and direction of rotation 2 is
shut down via terminals Y3 - Y4 (reversing starter only).
When the limit switch is open, the opposite direction of rotation can be triggered.
Note
Maximum conductor length.
The conductor length from the compact starter (Y1 - Y2, Y3 - Y4) to the limit switch must not
exceed 30 m!
With longer distances, a suitable coupling module must be used!
