Safe multiple operation
Multiple-application operation means that one set of control- lers can take control of up to three different applications at the same time. This makes it easy to handle simultaneous lifting, for instance.
Multiple controller operation means that the control can be shifted between three sets of controllers. Handovers may be appropriate in the case of long transfers where the view is blocked. Datek’s multiple operation ensures that only one controller/transmitter at a time can have control of the application. Operators have to make an active choice to transfer the control, either by relinquishing control or by taking control.
The controllers are equipped with a built-in start control, preventing startup in the event of safety-critical errors. LED indicators and audible signals inform the user as to what has caused the error. The controllers continuously send information to the receiver using a digitally verified protocol unique to Datek. In the event of even the smallest error arising, the receiver will immediately (<0.5 seconds) revert to a safe stop mode. Each Datek controller is assigned a unique ID code, ensuring that any given controller can only activate its own dedicated receiver. No other joysticks, transmitters or products can ever activate a Datek system.
The controllers are to be mounted in the arm rests of the chair in the machine ́s control cabin. Normally two controllers, left and right, are being used. However, for smaller applications only one control box can be used as a stand-alone item. As an alternative to the controllers, Datek can also offer customised control panels with joysticks and switches.
The cabin controllers are easy to install since they commu- nicate either by a single cable or by wireless radio with the receiver unit from Datek. The receiver units are available in many different versions supporting various field bus protocols as well as digital and proportional outputs.
The DC-20 controllers are backwards compatible and can substitute for Datek’s previous model of cabin controllers. This makes it possible to update an older system using a new controller without making modifications to the radio receiver and relay cabinet. Datek products are generally backwards compatible in terms of both hardware and software, so that we can provide the best possible service.
