Rolls Bridge Clip/Jumper Wire explanation

MA DE IN U SA

on off

OFF - POSITION

Rolls utilizes a way of switching with a three pin jumper wire system attached to the P.C.B. It uses an external bridge clip to act
as a switch for changing between two preset unit options.

-To switch between options the Bridge clip can be moved from one option/side to the other just like a switch.

-To do this simply grab the bridge clip with a pair of needle nose pliers or tweezers and pull outward from the unit
disconnecting it from the pins of the unit completely.

-The middle pin is utilized in either position. In the above illustration (OFF) the middle pin is connected to the left side pin with
the bridge clip to have the unit OFF.

-To select the (ON) position connect the middle pin and right pin together with the bridge clip as in the illustration below.

Please note that you must follow the silk screening of the unit to know what the jumper wire does and to which side is on or
off. All of our units are different, but great care is taken to insure that the silk screening is correct.
