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.
By re-registering the operator receives useful information necessary for his working procedures.
The large displays for cranes and machines become therefore, inapplicable, thus increasing the safety aspect of the operator`s work as his attention remains within his working field.
LEDs and displays show the operator all the information he needs. The display information can be programmed to suit the individual needs of the customer.
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.
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.
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.
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.
In the case of a pitch and catch operation, the crane can be controlled alternatively via two transmitters. One transmitter assumes responsibility for commands via an active request command. Only by an active release command is the crane given free and the other operator is able to have access to the crane again.
This option is the soloution when different operators at various locations in the area and have to transport loads across large distances.
The multiple address feature is an add-on feature for tandem-operation.
Up to 15 receivers can be controlled alternately from 1 to maximum 7 transmitters.
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.
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.
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.
The operator vigilance device can be selected via the transmitter software. It is an equivalent to the vigilance control system installed on the locomotive.
Unless the operator does not carry out actions on the transmitter at specific intervals of time (max. 30 seconds plus 7 seconds warning time) it is assumed that the operator is no longer controlling the locomotive with the necessary attention. In this case, the locomotive is brought to an immediate standstill by a rapid braking.
In addition to transmission of control signals from the transmitter to the receiver, data can also be transmitted from the locomotive back to the transmitter.
This can be e.g. speed of the locomotive, brake pressure, the set direction of travel or fault messages which is reported to the transmitter and can be displayed on a LCD.
LEDs and/or LCD show the operatro the needed information, at this the display of data can be customized individually. Up to three lines with 3x12 characters are displayed on the graphic-enabled LCD.
External antennas can be required when the portable transmitter is operated at a fixed place, e.g. inside a control room of a loading station.
The transmitter can be designed in a way that the receiving signal is automatically switched from internal to external antenna when the transmitter is put in the cradle for the fixed operation.
This feature is based on most modern RFID- technology. External control commands can be transferred safely and contactless into the transmitter without the need for a switch or mechanical connector.
2 sets of 5 white and very bright LEDs can be mounted onto the transmitter front. A warning signal is generated by flashing these LEDs in a fast and alternate mode. This supports the shunting process with pushed trains especially at night operations by alerting people in the vicinity of an approaching pushed train.
The throttle / bake counter is a software function of the transmitter which allows a simple adaptation of time-depending to position depending throttle and brake commands.
In addition to the normal 1 to 1 alignment between the transmitter and receiver, the receiver can also be controlled alternately by two different transmitters. For this purpose, each transmitter features a request and a release button to get control over the locomotive or for releasing the locomotive to pass the control to a second operator.
At any given time the locomotive can only be controlled by one operator. If one transmitter has already control over the locomotive, any request sent by the second transmitter is ignored and does not have any effect. The second transmitter is only able to control the locomotive after the first transmitter has released control over the locomotive.
This feature allows sharing the control over the locomotive, e.g. from a fixed transmitter at a loading station to a portable transmitter of an operator working in the yard.
In accordance with the ATEX directive II 2G EEx ib IIC T4 the transmitters of the TH-EC/LO series can be manufactured for the use in hazardous zones with explosive atmospheres, category 2, zone 1.
