LED Status Display
The device status will be indicated by 2 LEDs ("Power" and "MNS").
Once electrical power has been applied (connection of the network line), the following functional tests of
the two-coloured MNS LED are carried out:
• LED lights up green for a short time (ca. ¼ s).
• LED lights up red for a short time (ca. ¼ s).
