2.3.- BASIC OPERATION

The transmitter, in addition to monitoring the battery level and correct state of ingoing

orders, reads the state of the buttons or mechanisms and transforms them into a burst of bits,

which, after being processed by a GMSK modem and once sent to the radio transmitter, are

transmitted on FM, on the bands of 800 Mhz, 900 Mhz or 433 Mhz.

The receiver receives a burst on FM, on the bands of 800 MHz, 900 Mhz or 433 Mhz and

after verifying and processing it through a GMSK modem, it is converted into relay output.

The relay output is used to control the electric contactors of the crane. There are also

receivers which convert the output into tension values or current to be controlled by transformers

or electrically operated valves.

2.4.- BLOCK DIAGRAM

2.5.- SERIAL NUMBER

This is the name of the unit; it is used for the identification, tracking and history of a unit. It

is absolutely necessary in the event of any technical enquiry.

The serial number also indicates to us the manufacturing date of the unit, so as to know

whether a unit is within the guarantee period or not.

For example, unit 12060131 indicates that unit 131 was manufactured in December 2006.
