Advantages of cascading
Advantages of cascading:
•
Rapid connection, no additional external circuitry required
•
No optical mutual interference between the protective fields within a cascade.
Host and guests are operated with the same beam coding.
•
Resolution and protective field heights of the individual systems may be different
NOTE
If a sender does not have an additional guest connected to it, the extension connection
has no function and must be sealed with a protective cap.
Configuring cascading
No more than 3 systems can be connected in a cascade.
If your devices are in their as-delivered condition or have been reset to the factory
settings, you can connect them to each other. The devices recognize automatically that
they are part of a cascade.
Devices that are already configured and are to be connected in a cascade must be
reset to the factory settings.
Each device detects the number of devices in the cascade when it is switched on.
During configuration, the device stores this information in the configuration memory.
The information stored about the cascade is used to identify inadvertent or intentional
changes that could lead to a danger:
•
If fewer devices are detected in the cascade when it is switched on than were
stored in the configuration, every device in the cascade switches to the locking
state
•
If more devices are detected in the cascade when it is switched on than were
stored in the configuration, every device in the cascade updates its configuration
memory to the new value

Cascading new devices
Approach
1.
Install and wire the devices.
2.
Set the DIP switches for the beam coding on the receiver of the host system.
3.
Switch on the voltage supply.
✓
The devices are in configuration mode, the field indicator flashes green.
4.
Wait until all receivers indicate the correct cascade configuration. In a cascade,
diagnostic LED 2 flashes.
5.
Wait approx. 3 s longer.
6.
Receiver: to configure the restart interlock, press the reset pushbutton for
between 1 and 3 s, then release it. Diagnostic LED 4 flashes.
7.
Disconnect the devices from the voltage supply.
✓
The cascade can now be put into operation.
