Tools Needed:

Pliers

Align the safety sensors by moving the sending and receiving units in or out until the alignment light on the receiving unit comes on. The 1/4”-20 carriage bolt can be loosened to move the safety sensor in or out, as required. If you have difficulty aligning the beams, check that both mounting brackets are mounted at the same height and remount if necessary. Additional minor adjustments can be made by slightly bending the mounting brackets.

Once the alignment light comes on, tighten all bolts and mounting screws. Finish securing all wires making sure not to break or open any of the conductors. Loop and secure any excess wire.
