To start the muting function a high signal (24 V) must be applied to terminal 11

(muting activation) for 1 s�

Correct alignment of the muting sensors is imperative for the proper func-

tion of the safety relay�

8.4.1 Alignment of 2 muting sensors

1: Muting sensor 1

2: Muting sensor 2

3: Reector

4: Safety light curtain / safety light grid

5: Object

6: Hazardous area

• Align the muting sensors so that they can detect objects before they enter the

hazardous area�

• If an object is detected by both muting sensors S1 and S2 within 4 s, the mu-

ting function is active and the object can travel through the hazardous area�

• Both muting sensors must carry a high signal (24 V) while the muting function

is active�

Muting ends with one of the following conditions:

- after release of one of the two muting sensors

- when the time limit of 30 s has elapsed (timeout)
