Note: This FAQ is written based on the prevailing wiring most lift controllers use, always refer to the lift manufacturer documentation to ensure compatibility before attempting. Also the IP2CC/WF2CC has relays that are limited to 24v or 0.5 Amps (500mA). Always ensure that these limits are not exceeded.
Typical Lift Operation
Lift controllers (the circuit board that controls the lift) typically have 3 wires, "Up", "Down", and "Common" (COM).
Lifts typically have the following common actuations. If your lift has different actuations or different ways of triggering the actuations below then this FAQ may not be applicable.
- Up: Brings the lift to the up position. The Up action is created by connecting the Up wire to the COM wire.
- Down: Brings the lift to the down position. The Down action is created by connecting the Down wire to the COM wire.
- Stop (not all lifts): Stops the current travel of the lift. The Stop action is typically created by connecting both the Down and Up wire to COM simultaneously.
Some lifts will allow leaving wires connected in the Up, Down, or Stop modes (and will automatically stop the lift motors when the end of the actuation is reached). Other lifts will require the wires to be "pulsed" for a period and then returned to the open position. This is an important distinction as not following the proper actuation method can damage the lift. Which mode of operation is implemented does not affect the wiring, but does affect the control system/app programming.
It is also important not to program a Stop actuation on a lift that does not support it.
Wiring Lift actuations to the IP2CC/WF2CC
The IP2CC/WF2CC has 3 SPST (open/close), NO (Normally Open) relays. For lifts with the above actuations we will only need to utilize 2 of the relays.
- Relay 1 Terminal 1: Connect this to the "Up" wire.
- Relay 1 Terminal 2: Connect this wire to the "COM" wire.
- Relay 2 Terminal 1: Connect this to the "Down" wire.
- Relay 2 Terminal 2: Connect this wire to the "COM" wire.
In this wiring configuration, actuating relay 1 will result in the "Up" actuation.
Actuating relay 2 will result in the "Down" actuation.
Actuating both relay 1 and 2 will result in the Stop actuation.
Refer to your particular lift documentation on whether the relays need to be pulsed or can be left in the actuated state after triggering the actuation.
Tip: When lifts allow for leaving relays in the actuated state, a good programming practice is to send the command to open the other relays (that are used for the lift) before actuating the desired relay. This helps ensure that relays are not unintentionally actuated simultaneously.
