OMNEX FM Control System
The OMNEX FM control system is a microprocessor-based radio/tethered remote control system. It allows the operator to control the crane using FM radio signals or the digital RS485 protocol when connected to the tether. The system consists of a transmitter, crane receiver/control system, engine control radio receiver (optional), tether cable, and batteries.
The crane receiver is a self-contained control system. It contains the FM receiver, limiting system, and proportional valve driver. It receives power and safety circuit inputs (Anti
Two-Block and load sensor) from the crane. User inputs are received from the transmitter by FM radio signals or through the tether cable. Status LEDs are provided for user diagnostic. See the Omnex user manual insert for further details.
The transmitter is a hand held unit which sends user input to the receiver by FM radio signals or by the tether cable. Its features consist of an on/off/emergency stop push button switch, double acting momentary contract switches for each function, a 5 pin connector for attaching the tether cable, low battery light, and a transmit light.
For a proportional control, a trigger is provided for speed control.
The transmitter is powered by 4 AA batteries or from the crane power source when attached to the tether cable. To conserve battery power the transmitter will turn itself off if idle for 10 minutes.
The red battery light will begin to flash when the power is getting low.
The transmit light will illuminate any time a user input is being transmitted.
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. See the Omnex manual insert.
The transmitter may be turned off using the Emergency Stop button, or will turn itself off if left idle.
Activation of any switch will turn on the transmitter, however as a safety feature, the Emergency Stop must be pressed and released, or if already pressed, released within 10 seconds.
Release the Emergency Stop by twisting the red cap. A green band will be visible under the red cap once it releases.
Turn on power to the crane and ensure the receiver is also receiving power.
Select a function and press the toggle switch in the desired direction as indicated on the label.
After the function switch is activated, SLOWLY squeeze the trigger to operate the function.
If the trigger is pulled before a function switch is activated the crane will accelerate suddenly, causing the load to swing, and possibly fall or hit someone.
