Setting Shade Limits and Direction of Travel

The following procedures apply only to C2N-SSC-2 units with firmware

versions 2.2.0 or later. For prior versions, refer to the “Appendix” on

page 22.

When an ILT shade is first installed, the limits of travel normally come

“pinched” together so that the shade will not move up or down. Limits

and travel direction for an ILT shade are not set mechanically, but are

stored electronically in the shade motor itself. Limits of travel must be set

for each shade in order for the shade to operate properly. The six buttons

on the Shade Controller are used to set these limits. Shade limits can also

be set using the C2N-SSC-2 symbol. Refer to “Operation” on page 16 for

details on use of the buttons.

NOTE: Set the upper limit before setting the lower limit.

NOTE: Whether a shade rolls up or down when a particular button is

pushed depends on the orientation of the shade during installation as well

as how the shade material is mounted to the cylinder. If the shade moves

opposite to the direction required, the direction of travel can be reversed.

Refer to the last configuration procedure given on the next page.

NOTE: After a reversal, it is necessary to re-adjust the limits since the

reversal process again pinches the upper and lower limits together so that

the shade cannot move.
