5-2 Troubleshooting of ReceiverSymptom Cause RemedyPower is not being supplied. Check that the power supply capacity is sufficient.Connect the power supply correctly.Power supply voltage is out ofthe specified range. Set the power supply voltage correctly.All indicators are off.Connector is not connectedsecurely. Connect the connector securely.Fault indicator (yellow)lights up. Setting data of the sensor: errorCheck the noise status around the sensor.When using SF-HC (optional), reset the function.Even if the error is not cleared, contact PanasonicIndustrial Devices SUNX.[1 blink]Beam channel No. error Connect the end cap correctly.[2 blinks]Series connection errorConnect the cable for series connection correctly.Check the error contents of the sub sensor.[3 blinks]Total unit No. / Total beamchannel No. errorSet the number of series connection to 3 sets orless.Set the total number of beam channels for seriesconnection to 192 or less.[4 blinks]Extraneous light errorExtraneous light was detected.Prevent any extraneous light from entering thereceiver.[5 blinks]Control output (OSSD 1, OSSD2) errorWire the control output (OSSD 1, OSSD 2) wirescorrectly.Fault indicator (yellow)blinks.[6 or more blinks]Effect from noise / power supplyor failure of internal circuitCheck the noise status around the sensor.Check the wiring status, power voltage, and powersource amount.Even if the error is not cleared, contact PanasonicIndustrial Devices SUNX.All the beam-axisalignment indicators lightup in redLight is received on thebeam-axis which is set the fixblanking function from theemitter.Turn on the power after checking the setting status.The beam channels of theemitter and the receiver are notcorrectly aligned.Align the beam channels.OSSD indicator remainslit in red (light is notreceived). Emitter does not emit light. Check the emitter for error.If the device does not work normally after checking the items above, please consultPanasonic Industrial Devices SUNX.The blinking cycle of the fault indicator is shown as follows. Check the frequency of thelighting after passing approx. 2 seconds of the lighting off.© Panasonic Industrial Devices SUNX Co., Ltd. 2013 MJE-SF4A No.0038-55V- 73 -
