Use in accordance with the intended purpose . Use that is not in accordance with the intended purpose Warranty and liability . [. . . ] Deactivation of the sensor display reduces the sensor's current consumption by approximately 20 mA. 4-3-9 Reset Reset returns the sensor to the factory default settings. 4-4 Inputs/Outputs In total, the sensor can be operated with a maximum of three inputs/outputs. The functions of the inputs/outputs are user determined. Connector pin 4 is always defined as output (OUT). Connector pin 2 can be set as alarm output (ALARM), as test input (TEST). Connector pin 5 can be set as test input (TEST) or OFF. 4-4-1 Input: Test input TEST Connector pins 2 or 5 can be set as test input. The emitter is deactivated if a signal in the operating voltage range is applied to this input. Depending on the absence of a detection object the sensor alters it's output, because no light is emitted. 18 SECTION 4: Function 4-4-2 Outputs 4-4-2-1 Switching output OUT When a measured object is detected, the switching output OUT (Connector pin 4, fixed) switch in accordance with the sensor's output function settings. 4-4-2-2 Alarm output ALARM Connector pin 2 can be set as the alarm output. The alarm output is switched on if the intensity of reflected light from the reflector is too low. In this case, the sensor may be covered with dust. Please clean the sensor and check the alarm output again. This condition is indicated by the red LED too. 4-4 Inputs/Outputs 19 20 SECTION 4: Function SECTION 5: Transport 5-1 Packaging / Transportation damage · · · · During transportation, please ensure that the sensor is not damaged by other objects. For transportation, only ever use the sensor's original packaging sealed properly. Keep the sensor's original packaging for later use. Report transportation damage immediately in writing to the haulage contractor and OMRON. 5-2 · · Storage For storage keep the sensor in original packaging that has been sealed properly. Protect the sensor against dust and moisture. 5-3 · · · Scope of delivery The sensor's scope of delivery consists of: Retro-reflective Sensor E3NT-R Short-form instruction sheet CD-ROM containing the S3 software, this operation manual, the S3 software manual and the Acrobat Reader software. 5-1 Packaging / Transportation damage 21 22 SECTION 5: Transport SECTION 6: Mechanical installation of the sensor 6-1 Safety notes Assembly, electrical connection and maintenance must only be carried out by instructed, trained and authorized specialist personnel in accordance with applicable regulations, after de-energizing the power supply and with the machine switched off. The machine must be safeguarded against reactivation. Conversions and changes and tampering in the interior of the sensor, the data interface and the alignment tool are forbidden. During assembly, do not knock the sensor or drop it. The ambient conditions at the assembly location must conform to the technical data (see SECTION 3: Specification). 6-2 Sensor assembly For installation the following points should be considered: · · · · · · · The sensor is protected as far as possible against vibration and shock. The sensor is protected as far as possible against extraneous incident light. The sensor is protected as far as possible against damage and soiling. The sensor is installed in a way so that the electrical connection is possible. [. . . ] and keys.
