SG4-E INSTRUCTION MANUAL<br />
7.12 CODING<br />
The coding function allows the ESPE to remain in normal operation also when an<br />
interference condition with an other ESPE occurs, and in particular when the TX of the first<br />
light curtain radiates in the direction of the RX of the second light curtain. Obviously, both<br />
light curtains must be configured with two different codes (see also par. 2.2.2).<br />
No code<br />
In this situation no code is selected and the light curtains have to be installed at a certain<br />
distance from other light curtains with no code, in order to avoid possible interferences that<br />
can lead to a dangerous situation.<br />
If the user has to install the light curtains nearer than the minimum allowed distance he<br />
should take care to install the TX of the first light curtains on the same side of the RX of the<br />
second.<br />
Fig. 59 – No code<br />
Code 1 or Code 2<br />
When the user has to install two light curtains at a distance that is lower than the minimum<br />
distance allowed from homologous devices (and has to have the RXs on the same side), he<br />
has to configure the light curtains with different codes.<br />
The configuration by means of GUI changes the code only on RX side; in order to have the<br />
light curtain correctly working, the user has to configure TX side with the same code by<br />
means of BCM.<br />
