MKU™(Metal Keypad-U)

MKU Image

Equipment operators agree that the CattronControl™ MetalKeypad-U (MKU™) Operator Control Unit (OCU/controller) is perfect for heavy industrial applications. The MKU™ is the first Radio Remote Control product to combine the robust design requirements of the North American market with international safety requirements. The heavy-duty ruggedness of the MKU™ is suited for cranes, railroad, and any other industrial applications where the operator can be moved to a safer, more efficient location.

The MKU™ gives the operators of heavy equipment the best of both worlds; a small hand-held controller with a tough, metal housing for durability. All components are protected by a thick-walled, epoxy-coated extruded aluminum case and rubberized absorbing end “bumpers.” Standard MKU™ OCUs have pre-defined configurations and are fitted with a TransKey™ for added safety. Any MKU™ OCU will run any decoder as long as the correct TransKey™ is used, thus minimizing the need for specific spare OCUs. In addition, all function identifiers can be customized to the operator’s liking. Total water and dust sealing makes them ideal for indoor/outdoor applications thus giving the operator a reliable and extremely durable controller. This allows minimal worry or downtime so you can maximize productivity.

Options

Changing the RF-Channel
In order to ensure interference-free operation of a radio control system it may be necessary to change the RF-channel locally.

Changing the RF-channel can become necessary due to interference or the fact that a specific RF-channel is already in use. A change of channel can be performed either by reprogramming the TransKey or by reprogramming the transmitter. Reprogramming of the transmitter is performed using the transmitter keypad and requires no additional equipment.

Tandem Operation
In the case of tandem operation the receivers can be controlled alternately either via one or two transmitters. One transmitter assumes responsibility for commands via an active request command.

Only by an active release command the receiver is given free and the other operator is able to have access to the receiver again. This option is the ideal soloution where heavy or long products have to be transported simulteaneously by tow cranes operating in tandem.
