Reset button
Select the correct installation site for the reset button!
Install the reset button outside the hazardous area such that it cannot be operated from
inside the hazardous area. When operating the reset button, the operator must have full
visual command of the hazardous area.
The reset button is connected to
one
of the two Twin Sticks. If you connect a reset button
to both Twin Sticks, the system will not switch the OSSDs to the “ON state”.
Re-configuration after device replacement!
If you replace a safety light curtain with active Reset function with a replacement device,
the Reset function must again be activated. It is not sufficient to make the electrical
connections, because new devices are supplied ex factory with deactivated Reset function.
If you connect the reset button, then you must configure the function manually during
commissioning (see section 6.5 “Configuration of the Reset function” on page 55).
