Explanation of figure "signal processes"
Surveillance Monitored area for the light curtain
area
Test signal Must come from the lift controller and
is directed to SigIn
Relay Performance of the relay solenoid
Sig Out Semiconductor output
Status Semiconductor output, independent
of SigIn this output always shows the
status of the monitored area
SAFETY ADVICE
 A practical safety related circuit carries
out and checks this process before every
journey. If the process is found to be
incorrect, the journey is no longer allowed.
It is important to note, that the above
mentioned control function must also be
fail-safe, i.e. a fault may not lead to an
unsafe status.
 For a correct function, a continuous supply
of 24 VDC must be supplied to the SigIn
during operation 24 VDC.
NOTICE
At the circuit of the locking motor as well as at
the connection of external power relays, ensure
an appropriate elimination of fault (spark quench
device), see also Chapter 10.1 and 10.2.

Implementation

After installation, the opto edges must be connected to the
control unit light curtain. The blue plug (receiver edge) is
plugged into the receiver socket on the control unit light
curtain and the white plug (emitter edge) is plugged into
the emitter socket on the control unit light curtain. The
plugs have specially configured pins so that they cannot
be interchanged or connected incorrectly. Please ensure
that both safety clips of the plug are correctly engaged. The
plug is removed by pressing both safety clips.
Finally the ports of the plug terminals are connected (pay
attention to pin assignment).
The control unit light curtain has a microprocessor which
checks the entire light curtain system after power up. The
following procedures take place:

Figure 8:
Performance LED R & T after powering up the control
unit light curtain
After switching on the power, the "Power" LED must be
constantly lit. The LEDs "AlarmR" and „AlarmT" on the
control unit light curtain blink to signal that the self test is
being carried out for approximately 10 s alternately with
1 Hz (Figure 8). Subsequently, both LEDs will be constantly
lit for approx. 2 s. During this time the light curtains are
calibrated. Afterwards, both LEDs "AlarmR" and "AlarmT"
turn off.
The protected area has to be free during this process.
The system is now ready for operation without any other
adjustments necessary!
