The systems are programmable through a software on a PC so that the transmitter and receiver is configured as per crane electrical drawings. In case of complicated cranes there could be a substantial reduction in interfacing cost.
With the Program Copier program can be Copied and transferred to the receiver located on the crane platform. The program of one system can also be copied into another through the program copier facilitating interchange of systems between the cranes. Similarly the program in any of the systems installed can be copied into the spare Transmitter & Receiver
In the event of an unlikely failure of Emergency Stop button, if magnetic key switch is removed during the operation, the main line will drop. This additional safety feature was not available in the older systems.
Frequency crystals are plug-in and plug- out type and can be easily replaced by the user. Thus customer can maintain the systems themselves at cheaper cost rather than sending the full frequency cards for repairs. This also results in minimum inventory of spares.
Battery voltage check is continuously carried out while the system is in operation. The transmitter shows status of batteries in 3 stages. Green confirms healthiness of batteries and while in operation if LED changes to Orange, it means weak battery status. The batteries need to be replaced immediately so that no damage is caused to other PCBs due to weak batteries. Red would mean dead batteries.
Durable and Compact Receiver:
The receiver is very light in weight but more sturdy and easy to handle & install. The receiver has lamp indication to indicate that the communication between the transmitter and the receiver has been established. The receiver housing is of nylon fiber which is dust proof, bad conductor of heat, corrosion proof, with no possibility of signal being grounded and is best suited for uninterrupted radio signals.
To eliminate operator fatigue the weight of the transmitter has been limited. The weight of the hand held push button type transmitter has been limited to 350 gm or less and the weight of the shoulder held joystick type transmitter has been limited to 1000gms or less.
