Deactivating Reset and EDM
By deactivating Reset and EDM both Twin Sticks are reset to the delivery status.
As the system positions (host, guest 1 or guest 2) in a cascaded system are only defined
using the system plug and no position data is saved in the EEPROM, it is not necessary
to deactivate the system position.
If the device is to be used as the host for a cascaded system or as a standalone device
without Reset and/or EDM, Reset and/or EDM must be deactivated.
If the device is to be used as a guest in a cascaded system, it is not necessary to
deactivate the configuration.
The table below shows when the configuration of a Twin Stick, as described above, must
be deactivated.
The Twin Stick is to be used as:
Standalone or

After deactivating the configuration, check the wiring and if necessary modify to suit the
required function!
If, after the deactivation of the configuration, you want to re-activate EDM or Reset, you
must perform the necessary configuration again (see sections 6.5 and 6.6 on page 55).
How to establish the requirements for deactivating the configuration:
Ensure that the system or the machine is in a safe condition.
Ensure the Twin Sticks are aligned. The LEDs 1 to 5 (LED
Blue
) indicate the quality of
the alignment. At least three of the five LEDs must be illuminated for you to be able to
deactivate the configuration.
Switch off and on again the safety light curtain and start with the deactivation within 2
minutes.
