Commissioning and configuration
Commissioning requires a thorough check by qualified safety personnel!
Before you operate a system protected by the miniTwin2 safety light curtain for the first
time, make sure that the system is first checked and released by qualified safety
personnel. Please read the notes in chapter 2 “On safety” on page 8.
6.1
Display sequence during switching on
Both Twin Sticks must always be switched on at the same time. If you take one of the Twin
Sticks out of operation, you must briefly switch off the second Twin Stick prior to switching
on again.
After switching on the miniTwin2 safety light curtain runs through the power-up cycle. The
LED display indicates the device status during the power-up cycle.
The displays have the following meaning:

During initial commissioning of a stick, the LED flashes immediately to signal initial synchronisation between
the sticks. During all further power up processes, the LED only flashes if the previous system partner does not
reply within 20 seconds. In this case the communication can also be established with a replacement stick.
