                             KMFM CONTROL SYSTEM

The Liftmoore FM control system Model KMFM is a microprocessor-based radio remote control system, which allows wireless crane control.  The receiver connects to the standard crane control socket, just like the wired pendant, so it is easily retrofitted and does not prevent use of the standard wired pendant.

RECEIVER  

The receiver features encapsulated electronics for weather resistance and LEDs for user diagnostics.  It is mounted to the crane and connects to the crane control socket.  Upon user input, the receiver energizes the applicable function valves and/or solenoids, just as the wired pendant does.

TRANSMITTER

The transmitter is a pocket sized, hand held unit featuring an on/off power switch, push button switches for each function, and two diagnostics LED's.  It is powered by 2 AAA Alkaline batteries and includes a power saving feature, which turns itself off if idle for 2 minutes

DIAGNOSTIC LED's

There is a green and a red LED located inside the receiver and on the transmitter. 

The green LED will blink every ½ second if there is communication between the transmitter and the receiver.  It will blink every second if there is no communication.

The transmitter’s red LED will blink once every second if the batteries are low and need to be replaced. 

Error codes are indicated by a number of flashes of the red LED.  For example, 4 blinks and a pause means output number 3 has a problem.  See the trouble shooting section for more information.

MOUNTING

The FM receiver should be mounted so that it is protected from physical damage.  It should be as high as possible with the antenna pointing upwards.  A temporary mounting method, such as magnets or Velcro, is recommended so that it may be removed when not in use. 

OPERATION

Push the ON/OFF power switch on the transmitter and ensure the receiver is also receiving power. Select a function and the desire direction.  Press and hold the push button until the desire crane position is reached.

REPLACEMENT OF COMPONENTS

Each transmitter is encoded with a digital ID that is programmed to its specific receiver.  The receiver then only accepts signals from that transmitter so multiple cranes may be operated in the same vicinity without interference.  If either component needs to be replaced, the receiver must be programmed to accept the new transmitter ID.  Contact Liftmoore, Inc. for more information.

RETROFIT

The system design allows for easy retrofit. The only crane modification required is the simple addition of a ground wire to the control socket.  This does not prevent the use of the wired pendant.
