User manual LIFT-MASTER CPS-04-01

[. . . ] Either can be installed on the left or right of the door as long as the sun never shines directly into the receiving eye lens. The brackets must be securely fastened to a solid surface such as the wall framing. If installing in masonry construction, add a piece of wood at each location to avoid drilling extra holes in masonry if repositioning is necessary. The invisible light beam path must be unobstructed. [. . . ] The sensors are supplied with 36" long leads. We recommend the use of a liquid tight junction box near each sensor to make the connection to the sensor leads (Figure 4). Use rigid or flexible liquid tight conduit (depending on local codes) from junction boxes to operator. copper wire for connection between the sensors and the operator.

Remove the 270K resistor from the A & B terminals. Connect 2-wire coil cord or cord reel to the A & B terminals. For a 4-wire safety edge using a 2-wire coil cord; 1. Remove the 270K resistor from the A & B terminals. Add the resistor to 2 of the 4 wires at the safety edge, connect the coil cord to the other 2 safety edge wires (Figure 1). Connect the 2-wire coil cord or cord reel to the A & B terminals. NOTE: If the LiftMaster® photo eyes are not being connected you must remove the JU1 and R16 resistors from the CPS3CARD.

Logic 3 Board will have the same connection. The maximum door edge resistance should be less than 1000 ohms as measured between any 4 conductors. This measurement should be taken when the door edge is in the closed contact state.

The operator will not close if the indicator light in either sensor is not glowing steadily, alerting you to the fact that the sensor is misaligned or obstructed. NOTE: For non-solid state operators, if the door is stopped in a mid position, activation of the sensors will cause the door to open. This is similar to activating a sensor edge. [. . . ]
