Electronic Deadman Control

The electronic deadman control shall prevent an unintentional use of a joystick, which can cause unwanted movement of cranes or machines.

The operator has to release the joystick by putting it back to the neutral position before giving the ultimate command. Without this release the joystick will not react and no commands will be conveyed from transmitter to receiver.

After the release, the joystick remains active until it returns to the neutral position and remains there for set amount of time. The active/inactive status of the joystick is indicated by a LED on the transmitter.

This feature can be set for a drive, a joystick or even two joysticks.

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.

Man-down Alert

As operation of a remote control always requires the operator to be in an upright position, the transmitter has a tilt sensor which monitors whether the transmitter and thus also the operator are in an upright position.

If the transmitter or the operator are no longer in an upright position, a warning signal will sound after a brief period; this warns that the transmitter is in a tilted position. Unless the transmitter is not returned to an upright position or a certain button is not pressed in order to extend the tilt period, the crane or machine is automatically brought to a standstill by a forced braking.

Maximum Transmission Power

For increased range the standard RF-unit with 10 mW transmission power could be replaced with a RF-unit with up to 500 mW transmission power.

Stationary Transmitter

When the circumstances do not allow for the use of a portable transmitter, a stationary one can be implemented, e.g. if the operator can only operate from the control console in his crane or another vehicle, the stationary transmitter is of great use.

Data transmission from machine to machine or the interlocking system of a conveyor belt is another good example of further application areas.

Infrared Start-up Feature

The infrared start-up feature for radio remote controls is a safety feature. The radio remote control can only be activated if the transmitter is within the vicinity and in view of the receiver. This ensures unintentional crane or machine activation.

IR-Range Limitation

The use of the infrared range limitation makes sure that the remote control can only be operated whilst the transmitter is in the IR-beam of an additional infrared-transmitter. This ensures that the operator has to be in a position within sight and near the load to be able to control the crane or machine.
