Place the Lift Stopper controller in a weather-protected location so that:
Important Note: Ensure that the Lift Stopper Controller and all downstream devices (lift switch and lift motor) are protected by a GFCI. If not already installed on the lift circuit, you can purchase an inline GFCI here that can be installed on the Controller's power cord.
Depending on the application, you may use one or more limit switches or IR beam devices as your limit sensor. The lift will stop and an alarm will occur if any of the sensors is triggered. If multiple sensors are used, they should be connected in parallel, either as a “daisy chain” (shown above) or a “home run” configuration, to the 4-conductor Sensor Cable that extends from the left side of the Lift Stopper controller. Limit Sensors are wired to the 12-volt DC Sensor Cable as follows:
Limit Switch: Connect the green and white wires in the Sensor Cable to the NO (Normally Open) terminals on the limit switch. Ensure the unused red and black wires in the cable cannot touch and short each other.

IR Beam: One of the two IR devices provided is a receiver and the other is a transmitter. The receiver has four wire terminals, the transmitter has two.
Wire the receiver to the Sensor Cable by connecting the black wire to the '-' (1st) terminal on the receiver, the red wire to the '+' (2nd) terminal, the green wire to the 3rd terminal, and white wire to the 4th terminal. Also ensure the jumper in the receiver is in the NO (Normally Open) position.
For the IR transmitter, only the black and red wires are required, and they should be connected as described for the receiver. Ensure the unused green and white wires in the cable cannot touch and short each other.
____________________________
Note: If multiple sensors are wired in a “daisy chain”, ensure that each of the four wires (red, black, green, and white) in the current section of the chain are connected to the wire of the same color in the next section.
Limit Switch: The limit switch should be attached to the ceiling so its lever is deflected by the cable when it is wound to the maximum desired lift height. As shown above, the lever should extend so it will be deflected by the cable if it is wound above or below the cable winder. This protects should the lift motor be left “On” in the down position, causing the cable to totally unwind and then raise the lift as it rewinds on the opposite side of the cable winder.
IR Beam: As described in the instructions provided with the IR sensors, the IR transmitter and receiver should be mounted below the boathouse ceiling at the maximum height that you want the lift to reach. They must be less than 40 feet apart and pointed at each other so the IR beam sent by the transmitter is:
The diagram above shows a representative installation, with the IR beam on a diagonal between the front and rear piles.
After all pieces are mounted and electrically connected:
