Operating Procedures: Photoelectric Sensors E3C-LDA 1 Setting the Operation Mode To restore the default power settings: The operation mode is set with the Mode Selector Switch. Operation mode Light ON Dark ON DOWN Operation L-ON D-ON L D PTUN OFF "OFF" will flash twice. Light level *Setting Errors An error has occurred if one of the following displays appears after the progress bar is displayed. Adjusting the Power (RUN Mode) The current incident light level can be adjusted to near the power tuning target value (default: 2,000). Display *Confirm that the MODE Key setting is PTUN (power tuning). The default setting is PTUN. Threshold (default) Error Action PTUN Flashes twice Over Error The incident light level is too low for the power tuning target value. OVER The power will not be tuned. The power can be increased up to approximately 1.5 times the incident light value. PTUN Flashes twice Bottom Error The incident light level is too high for the power tuning target value. BOTM The power will be turned to the minimum level. The power can be decreased down to approximately 1/8th the incident light value. light value. ➜Refer to 5. Setting Functions in SET Mode on page 18. Light level Threshold The Power Tuning indicator will go out when the default setting has been restored. *Advanced Twin-output Models (Same for All Adjustments): Set the Channel Selector Switch to the desired channel before making any adjustments or settings. Set the SET/RUN Mode Selector Switch to RUN. Press both for 3 s. (Factory-set) *Advanced Twin-output Models: The operation mode is set in SET mode. ➜Refer to 5. Setting Functions in SET Mode on page 18. 2 MODE RUN (Factory-set to RUN) 3 Setting Thresholds Manually (RUN Mode) MODE 3s PTUN A threshold can be set manually. A threshold can also be finetuned using manual setting after teaching. Progress bar Release the key after the progress bar is displayed. Set the SET/RUN Mode Selector Switch to RUN. Light level Threshold (default) RUN Display changes after specific time. (Factory-set to RUN) UP Power tuning target value The Power Tuning indicator will light when the adjustment has been completed. Light level Increases threshold. Threshold DOWN Decreases threshold. *Even if the display method for display switching is changed, the threshold will appear on the sub-display when the key is pressed. 16 Operating Procedures: Photoelectric Sensors 4 Teaching the Threshold (SET Mode) *There are three methods that can be used for teaching, as described below. Use the method most suitable for the application. *Teaching (with/without workpiece teaching and automatic teaching) can be performed in RUN mode. For operating procedures, refer to Instruction Sheet provided with the product. *An error has occurred if OVER, LO, or NEAR is displayed on the sub-display. Repeat the operation from the beginning. 4-1. Teaching a Through-beam Fiber Unit without a Workpiece A value about 6% less than the incident light level (minimum difference) can be set as the threshold. This method is ideal when detecting very small differences in light level, such as when detecting very fine workpieces or transparent workpieces with a Through-beam (retroreflective) Unit. Set the SET/RUN Mode Selector Switch to SET. Light level 4-2. Teaching a Reflective Fiber Unit without a Workpiece A value about 6% greater than the incident light level (minimum difference) can be set as the threshold. This method is ideal when using a Reflective Fiber Unit to detect workpieces so that detection is not influenced to any great degree by dust and other environmental factors. Set the SET/RUN Mode Selector Switch to SET. Light level Threshold SET UP DOWN Either for 1 s With no workpiece: TECH Threshold ---- "- - - -" will be displayed. SET UP UP DOWN DOWN Either for 3 s Either for 1 s With no workpiece: TECH ---- RFCH Threshold Light level Threshold The threshold that was set will flash twice. "- - - -" will be displayed. RUN To RUN THRU The previous display will return when the setting has been completed. Threshold The threshold that was set will flash twice. 4-3. Teaching With and Without a Workpiece Two points, with and without the workpiece, are detected, and the intermediate point is set as the threshold. The previous display will return when the setting has been completed. Light level Threshold Set the SET/RUN Mode Selector Switch to SET. Light level Threshold SET UP DOWN Either for 1 s With a workpiece: Workpiece TECH ---- "- - - -" will be displayed. UP DOWN Either for 1 s With no workpiece: RFCH Threshold Light level Threshold The threshold that was set will flash twice. The previous display will return when the setting has been completed. 17 Operating Procedures: Photoelectric Sensors 5 *The function transition boxes show the default settings.
