Signal Meaning Source
ESPE Electrosensitive protective equip‐
ment
Function-tested 0 active local signal (terminal X6,
"Input 1")
SR Pressure-sensitive edge Function-tested 0 active local signal (terminal X6,
"Input 1")
Con󹪝guration of the connected sensor type
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
Note that, internally, some signals (e.g. ESPE and LB) are logically ORed (corresponding to the
depiction in the "Sensor signals" 󹪝gure). If the signal logic is con󹪝gured for ESPE or SR, the
TestOUT function test signal is generated automatically.
An ESPE* can be connected to the SIDOOR ATD4xxW control units.
* according to DIN EN 61496-1:2013: Safety of machinery - Electrosensitive protective
equipment – Part 1: "General requirements and tests"
Take into consideration the following:
• ESPE of type 2 usually have PL c
• ESPE of type 3 usually have PL d
• ESPE of type 4 usually have PL e
• The resulting overall PL, for example, is to be determined according to EN ISO 13849-1: 2015
Section "6.3 Combination of SRP/CS to achieve an overall PL" (series connection subsystems:
sensors, switchgear if applicable, ATD4xxW):
– For type 2 ESPE, the resulting PL is maximum PL c (limitation by light curtain)
– For type 3 or type 4 ESPE, the resulting PL is maximum PL d (limitation by ATD4xxW)
The following 󹪝gure schematically shows the interconnection of a type 2 ESPE with the SIDOOR
ATD4xxW control unit:
