Page 5: General
The ESPE consists of an Individual Light Barrier Control Unit to which as many as four sensors can be connected. Use of the Individual Light Barrier Control Unit is only permitted with wenglor SL2-00 Light Barriers (see section 13 for order designations). Safety category 2 and Performance Level c is otherwise not assured. -

Page 7: Brief Explanation
1.4 Brief Explanation Contactor Monitoring An operating mode for which switching performance of the contacts at an external relay is dynamically monitored. The contacts must close fully within a specified period of time. Muting Mode Objects can be fed through the safety field without switching the safety output in this operating mode. OSSD (Output Signal Switching Device) The output of the contactless safety device which is connected to the machine controls. -
Page 8: Securing The Danger Zone
2.2 Securing the Danger Zone The danger zone must be secured by means of the light barriers alone, or by means of the light barriers in combination with additional mechanical safety devices. Reaching around, over and/or under the safety field must be prevented in any case. -
Page 9: Perpendicular Approach To The Safety Field
2.3.1 Perpendicular Approach to the Safety Field A minimum installation height of 750 mm from the reference level is required for the use of a light barrier C = Margin for penetration into the dan- ger zone before the safety device is tripped (never <... -
Page 10: Parallel Approach To The Safety Field
2.3.2 Parallel Approach to the Safety Field If this safety concept is used, the height of the safety field (H) may not be any greater than 1000 mm. If H is greater than 300 mm (or 200 mm for non-industrial applications, e.g. if children are present), one runs the risk of inadvertent, undetected access from underneath the safety field. -
Page 11: Mutual Interference Of The Light Barriers
After the light barriers have been mechanically mounted (see operating instructions for SL2-00), the SS2-00VA000R3 control unit is linked to the machine’s controller. The OSSD outputs must be connected to the machine’s safety circuit such that safety category 2 is still complied with. -
Page 12: Notes Regarding Connector Cables
If several control units are mounted next to each other, a minimum clearance of 2 cm must be maintained between the units in order to avoid overheating. The control unit must be provided with 24 V DC ± 20% supply power. External power supply must comply with EN 60204-1. -

Page 18: Inputs
4 Inputs 4.1 Test Input A self-test is started at the control unit by applying 24 V DC to the test input (terminal 16). When the control unit’s safety inputs are activated, the control unit indicates that testing is being executed by shutting down the transmitters at the connected safety light barriers, and thus simulating penetration of the protected area. -

Page 22: Outputs
• 0 V is applied to the output when muting is deactivated. • 24 V DC is applied to the output when muting is active. The muting indicator is an optical indicator lamp (e.g. wenglor’s SM0-00CA000C1). This output is also a PNP output. -
Page 23: Connecting The Muting Sensors And The Muting Indicator
• The sensors should detect the material only, and not the means of conveyance (e.g. pallet). Muting Sensor Muting Sensor sensors should detect load, and not the pallet. Material Pallet Conveyor Level • The material must be detected throughout the entire muting zone, i.e. the sensors’ output signals must remain unchanged. -
Page 24: Selecting A Muting Duration
Muting is only possible when the entire muting system is connected. This includes both muting sensors and the muting indicator. Any wenglor light barrier with an antivalent PNP output (the output must read out 24 V as long as the light beam is unobstructed) can be used as a muting sensor. -
