2.7 Approvals and IP Protection RoHS 3. Product Description The SEFG safety light curtain is a piece of electro-sensitive protective equipment (ESPE) used to safeguard danger points, danger zones and accesses to machines. The ESPE monitors the safety field between the emitter and the receiver. When an object penetrates the safety field and one or multiple beams are interrupted, a switch command is triggered on both safety outputs.

Page 36 Safety field The safety field is the area of the ESPE where an object (e.g. person or object) is detected according to the resolution. Safety field height The safety field height describes the dimension of the range within which a standardized test object (test rod) is recognized by the ESPE.
Page 37: Securing The Danger Zone
5.1.2 Securing the Danger Zone The danger zone must be secured by means of the ESPE alone, or by means of the ESPE in combination with additional mechanical safety devices. Reaching round the sides, over or underneath must be prevented. The danger zone may only be accessible via the ESPE’s safety field.

Page 57: Muting
5.2.4 Muting Muting is a function that safely bridges the ESPE for a short time so that objects can be moved through the safety field without the OSSDs switching off. The muting cycle is activated as soon as the responsible sensors detect an object. When arranging them, it is therefore important to ensure that the muting cycle can not be triggered by a person.
Page 58 (e.g. from a sensor). NOTE! • For easy initial start-up, wenglor offers muting sets (Z2MGxxx), which can be mounted directly on the ESPE or the safety column Z2SSxxx. • Further details are available in the standard IEC 62046.

5.2.4.2 Muting Visualization • The receivers have an integrated illuminated cap (see “5.2.6.4 Integrated Indicator Lamp” on page 102), which shows the muting status. • A continuous white light signals an active muting sequence. • It is also possible to connect an external muting lamp on the signal output. 5.2.4.3 Cross Muting Cross muting enables an object to be transported in or out of the danger zone.

Page 72: Belt Stop Signal
5.2.4.7.3 Belt Stop Signal The parameterizable “belt stop signal” function enables a high system availability for applications where the conveyor belt is stopped operationally. It stops the muting sequence temporarily. To this end, if there is an active signal on the “belt stop signal” input, the timers that monitor the initiation and maintenance of the muting sequence are paused.
Page 73: Muting Enable
5.2.4.7.4 Muting Enable The “Muting Enable” function is intended to provide added safety for the user when working with muting. If the function is activated during parametrization, the “Muting Enable” input is evaluated. The muting can now be enabled or blocked using the external Muting Enable signal. If the Muting Enable input is active, muting is initiated with a valid muting sequence.
Page 74: Direction Setting (Only For 4-Sensor Muting)
5.2.4.7.5 Direction Setting (Only for 4-Sensor Muting) This function increases the safety during muting by specifying and checking the sequence of the activation and deactivation of the MS. If an object passes through the safety field in a direction other than the one de- fined, the muting cycle is not initiated.
Page 75: Partial Muting
5.2.4.7.7 Partial Muting The “Partial Muting” function can be used to secure the danger zone even more effectively. With this ap- proach, only part of the ESPE (e.g. at object height) is hidden within a valid muting sequence, while the other light beams remain permanently active and cause the OSSDs to be switched off if interrupted.
Page 76: Full Muting Enable
5.2.4.7.8 Full Muting Enable For applications where the object height varies, the muting can be extended to the total safety height of the ESPE at specific times with the “Full Muting Enable” function. This function should only be used if “Partial Muting”...
Page 77: Gap Suppression
5.2.4.7.9 Gap Suppression For transport items with gaps, brief interruptions in the muting signal are to be expected. The “Gap Suppres- sion” function ensures that a brief interruption in the detection does not result in the muting being terminated. If the function is activated, interruptions of up to 250 ms are accepted in the signal from a MS. DANGER! •...

Page 79: Blanking
5.2.5 Blanking Blanking is required for applications including objects which continuously protrude into the safety field, thus interrupting specific light beams of the ESPE. In order to maintain a high availability of the application even under these conditions, the interrupted beams are excluded from the evaluation during “blanking”. A safety field penetration at any other point of the ESPE switches the OSSDs and stops the hazardous motion.
Page 80 DANGER! • The blanking function poses increased risk, as the hidden area of the safety field is not monitored for penetration. • Additional measures, such as mechanical protection (see Figure 19), should be used to prevent reaching through the hidden beams. It must not be possible to reach through the “shade”...
Page 81: Fix Blanking
5.2.5.2 Fix Blanking If a fixed object is always located in the same position in the safety field, “Fix Blanking” can be used to hide individual beams.

Page 82: Conditions Of Use
5.2.5.2.1 Conditions of Use • If a non-hidden beam is covered, this is classed as a penetration and the OSSDs are switched. • Hidden areas are monitored. Beams must not be detected in this area (“monitored blanking”). I.e. they must always be covered by the blanking object. If a hidden beam is uncovered, the receiver enters error state.
