3.3.4 Multicolor indicator
(Optional for MLD 320, MLD 330, MLD 335, MLD 520, MLD 530, MLD 535 as well as for MLD 510/AS-i,
MLD 510-...M/A)
The multicolor indicator signals the OSSD state see table 11.1. In addition, during muting a constant white
light signals that muting has been started correctly and that the protective function has been bridged. A
muting error is signalized by blinking see table 11.2.
3.4
Integrated laser alignment aid
(Optional for MLD 310, MLD 312, MLD 320, MLD 510, MLD 520)
The laser alignment aid is optionally available for transmitter-receiver systems. There is a red light laser
on the transmitter side of each light axis. The laser beams can all be switched on simultaneously via
MagnetKey. The sensor for the MagnetKey is located next to the transmitter's first light axis. The laser
beams remain active for approx. 10 min and then switch off automatically see chapter 8.5 „Aligning with
integrated laser alignment aid“.

Alternatively, the laser can also be activated for approx. 10 min by a signal on the transmitter. To
do this, a change has to be made from 0 V to 24 V on PIN2, e.g. with a connected button see
table 7.1.
