Siemens SIDOOR ATD4 W Series - Espe

4.4.1.2 ESPE
Function description
A light array / light curtain is the part of the electro-sensitive protective equipment (ESPE) that
is connected to the machine control system and assumes a de󹪝ned state when the sensing
device is triggered during intended use.
Connection and parameter assignment
An ESPE can be connected to SIDOOR ATD4xxW control units via "Input 1" of the terminal X6.
An ESPE with type 3 or 4 OSSD outputs can also be used by using switchgear. You can 󹪝nd
additional information in the section Sensor technology and external sensor connection
(Page 166).
If the SIDOOR control unit's sensor logic is con󹪝gured for ESPE, the "TestOUT" function test signal
is output automatically at the terminal X100.1 (ATD420W, ATD430W) or X12 (ATD401W). See
section Sensor function test (Page 170).
The sensor type of the sensor connected to "Input 1" of terminal X6 can be con󹪝gured as follows:
• Parameter p4600
• Service menu: MAIN MENU > General setup > Special parameters > Function Input 1
The travel range within which the control unit reacts to the OSSD signal can be restricted by
parameter p1210 (see section Calibration and function parameters (Page 192)).
You can 󹪝nd a schematic connection as well as detailed information on the connection of an
ESPE in the Overview (Page 166) section.
Note
The light barrier, DCOPS, ESPE or pressure sensitive edge functions cannot be implemented
simultaneously as sensor functions at Input 1.

Signal Meaning
1 (voltage applied) Light curtain is not interrupted.
0 (voltage not applied) Light curtain is interrupted*.
* The response of SIDOOR ATD4xxW control units also depends on the particular system mode. See the
