7 Functions of the SD3-A1
The SD3-A1 is equipped with the X1 and X2 interfaces. The following functions are
available through them:
7.1 Restart
Depending on the operating state, the restart input X1-2 has several functions:
To activate the functions, apply 24V to input X1-2. In the meantime, the safety outputs
OSSD 1 and OSSD 2 are switched OFF; the indicator at the scanner (LED 3) is lit up red.
The duration of the signal must be between 0.12s and 5s.
The restart input X1-2 must be connected to an external, permanently installed button.
X1-2 must not be connected with the remaining controls in order to prevent an unintended
release with a restart pulse under some circumstances.
Force-guided, normally closed contacts can be monitored in the restart circuit (relay
monitoring).
Please note the Chapter 5 (Information for Planning and Mounting) and 9.1 (Electrical
power supply).
7.2 Channels for zone pair changeovers, FP 1 to FP 4
To activate the zone pairs, apply 24V (see Chapter 9.1) to the following inputs:
The following points also apply for the switchover:
If these points are not observed the laser scanner will fail within 40ms and will show this
with the additional 2Hz flashing of the green LED 1.

Enables the restart interlock following the interruption of a detection zone
x
Enables the start interlock following a system start
x
Restarts after a device error has been eliminated
x
Recognizes a defined enable signal
after a device error
after a detection zone interruption for enabling the restart interlock

X1-4 (FP 1)
x
X1-6 (FP 2)
x
X1-7 (FP 3)
x
X1-8 (FP 4)

The switchover must be made within 40ms, i.e. after 40ms one of the input
connections shown in Table 6.1-1 must be valid and provided stable. During the
switchover time the old zone pair is monitored; the new one after max. 80ms.

The switchover process executed by the control unit must concur with the laser
scanner’s configuration, which was set beforehand with SD3SOFT .
