8.1.2 FSS output (Frequency Safety Signal)
The FSS is a 1 kHz safety output allowing for safeguarding according to EN ISO 13849-1:2015, without using a test signal.
As long as the safeguarded area is free, the FSS output sends a 1 kHz signal. When an object enters the safeguarded
area (OBJECT DETECTED), the FSS output switches to LOW/GND (0 V). When the object leaves the safeguarded area (NO
OBJECT) the frequency starts again (Chapter 9).
8.1.3 Output 1 - factory settings
Output 1 is delivered in the following versions. The settings refer to the "ee" type description (see Chapter 4.3).
Other options are available on request.
8.1.4 Output 2 - factory settings
Output 2 (PNP/NPN) is delivered in the following versions. The settings refer to the "ff" type description (see
Chapter 4.3).
Other options are available on request.
8.2 Test input
To fulfil EN ISO 13849-1:2015 the GridScan/Pro with PNP/NPN output (N type) must be tested by the door controller
before each door closing cycle. The GridScan/Pro is available in a standard version with "Test active LOW".
Important: When the FSS output is used, using the test input is not necessary to achieve safeguarding according to
EN ISO 13849-1:2015. In this case, the white wire has to be connected to the USP.

Output 1 (FSS)
, ee - - Output 1 switches when person/object is detected or 3 seconds after door closure
(reactivates when the 11th element from bottom is uninterrupted again).
ST type Output 1 switches when person/object is detected.
, ff - Standard - no Output 2
, 2Z Output 2 switches when person/object is detected using the single-element detection method (11th element
from the bottom, 490 mm).
, 2Y Output 2 switches when person/object is detected using the single-element detection method. In this case,
the element will be blanked during door blanking (11th element from the bottom, 490 mm).
, 2X Output 2 switches immediately after door closure (reactivates when the lowest element is uninterrupted
again).
