Read and understand all instructions before beginning installation. Disconnect power to motor and test upon
completion. Wireless sensing edge systems should be installed by qualified personnel to ensure the requirements
herein have been met. Keep these instructions with the installation. Always abide by local and national electrical code
specifications when wiring accessories to motor controls.
Avoid visible cords and reels with the Two-Channel Wireless Edge Receiver (MWR22B) and Transmitter (MWT12B
and/or MWTA12B) System. This system is designed to provide a wireless signal transmission from a non-monitored
sensing edge to motor controls with on-board diagnostics for easy setup and troubleshooting. The transmitter is
available with an optional audible alarm that activates when the battery has 25% of power remaining. Consult your
manual for detailed instructions about connecting to the motor.
