IKUSI reserves the right to change this information without prior notice.
In order to return to the operating mode, all the worker has to do is move back into the working zone.
Movement orders must be disabled in order to restart movement. Once the transmitter enters the
working area, movement orders will not be ready to be used unless they have gone to zero. This is to
make movements start in first speed. If the remote control is provided with a Display, whenever the
transmitter is out of range, the message “Out of Range” will be displayed.
The remote control has got 4 modes of operation defined in the EEPROM:
1.- Range Limiter only at start up (Electronic Key): In order to make the transmitter work, it is
necessary that the transmitter is inside the starting zone, defined by the position of the infrared
transmitter.
2.- Range Limiter only in operation: The transmitter can be started anywhere inside or outside of the
working area, but the movement orders will not work until the transmitter is inside the working zone.
3.- Range Limiter at startup and operation: The transmitter in order to work must be inside the working
zone always.
4.- Range Limiter only as an output Relay: This functionality makes the transmitter not to show In
range or Out of range situation in the transmitter itself. It will not mask any order. The information will
be sent to the receiver in order to process the information as an output relay or a condition to the relay
table.
11.2.1 – LA70 INFRARED TRANSMITTER
This is the element installed in the crane, which generates the infrared modulated radiation with an
identity code, which permits the sensor its identification.
Emission angle in long travel direction is wider than those of cross travel direction. In this way, the
working area covered by a transmitter is similar in shape to an ellipse, whose dimensions depend on
the height of the bridge over the ground. Approximately, the diagonals of the ellipse according to the
height are the following:
h (m)
D (m) ±63º
d (m) ±40º

In cases in which it is believed that the area covered by one transmitter is not enough, more slave
transmitters can be installed.
