    And there are no sources for damage around the wiring. In case of connecting more than two products, it is configured to use dedicated series connection cable and mutual interference prevention. In case of the series connection for more than two products, use dedicated series connection cable, and it is configured not to be extended or arbitrarily connected. The wiring is suitable for each application and is configured not to be connected upper side of the product (e.g., wiring for the series connection cable and lamp output cable) and the lower side of the product (e.g., the power I/O cable) in reverse. The wiring and end cap connected to the product are firmly secured to prevent separation during use. The product is connected to the safety-related part of the control system using two OSSD control outputs and configures the safety system. In case of the product is set to PNP output, two OSSD wires are not shorted to +24V. In case of the product is set to PNP output, the load connected to two OSSD wires is connected between the OSSD wire and 0V. 11 In case of the product is set to NPN output, two OSSD wires are not shorted to 0V. In case of the product is set to NPN output, the load connected to two OSSD wires is connected between the OSSD wire and +24V. In case of the auxiliary output (AUX 1/2, Lamp 1/2), it is configured to prevent the connection to the safety- related part of the control system. © Copyright Reserved Autonics Co., Ltd.

    In use of the EDM function, short the EDM input and then put the test piece in the detection zone (NPN output: 24VDC, PNP output: 0V). The light curtain will turn into lockout condition. At this time, the OSSD indicator lights red, and the two OSSD control outputs are turned OFF and maintain the status. In use of the start interlock function, the OSSD indicator remains red when the product is turned on with no test piece in the detection zone. The two OSSD control outputs are turned OFF and maintain the status. After that, the reset input is applied, and the OSSD indicator lights green, and the two OSSD control outputs are switched to ON and maintain the status. In use of the restart interlock function, the OSSD indicator remains red even though the test piece is inserted and removed while the OSSD is ON state, and the two OSSD control outputs maintain OFF state. After that, the reset input is applied, and the OSSD indicator lights green, and the two OSSD control outputs are switched to ON and maintain the status. In use of the muting function, the muting sensor operates in normal state. In use of the muting function, the muting starts when the specific conditions are met. At this time, when the test piece enters into the detection zone, the OSSD indicator maintains green, and the two OSSD control outputs remain ON state. In use of the muting and override function, the indicators (e.g., alarm lamp) installed where it can be seen from all sites are in normal operation. 12 In use of the fixed blanking function, there is a fixed object in the blanking zone. ※1:  W hen inspecting the product using the test piece, move it in the order below.
