E3X-ZV Fiber Amplifiers, Communications Unit and Accessories Operating Procedures Convenient Setting Features Various Smart Tuning Methods Convenient Settings When Received Light Intensity Decreases due to Dust or Dirt Preventing Malfunction • Maximum Sensitivity Tuning Long-press the button for 3 seconds or longer in the presence of a workpiece in • Key Lock Function Disables all button operations. the case of through-beam type or without the presence of a workpiece in the case of reflective type, and then take your finger off the button when [ ] is displayed Enable / Cancel (Same procedure) on the green digital display part. Hold both the button and the button for 3 seconds or longer.
The green digital display changes [ ] [ ]. * Press either of the + or - button. Incident light level setting: The incident level when the button pressed is adjusted to "0". Threshold setting: The value is set to approx. 7% of the incident light level when the button pressed. If the incident light level when the button pressed is smaller during Returning Received Light Intensity Display to “0” correctly turned ON will be set.

When DPC (ATC) function or the differential output modes are performed, the zero reset cannot be performed. button for 3 seconds or longer. through while [ ] [ ] [ ] is displayed in green digital.
(Keep holding the button while the workpiece passes through, and hold 7 seconds or longer until [ ] is displayed in green digital. After the workpiece passes through, release your finger from the button.) Incident light level setting: Adjust the max. incident light level while pressing the Cancel button as the power tuning level. Threshold setting: Set to the middle between max. and min. incident light levels Hold both the button and the while pressing the button. button for 3 seconds or longer. Determine Workpiece Position When released, [ ] is displayed. The threshold also changes accordingly. The lower threshold limit is -1999. • Position Tuning 1.
Press the button without a workpiece in the area. For Stable Detection Regardless of Received Light Intensity Changed due to Dust or Dirt The green digital display changes [ ]. 2. Place the workpiece at the desired position and hold the button • DPC Function (Dynamic Power Control) for 3 seconds or longer. The green digital display changes [ ] [ ]. Use this function with through-beam type or regressive reflection type. Incident light level setting: The Step 2 incident level is adjusted to half the power tuning level. Turn on DPC function in SET Mode Smart Tuning in Detection Mode Threshold setting: Set to the same value as the Step 2 incident level.
Stabilizes the displayed incident level by correcting internal incident level changes. Incident Light Level Displayed incident light level Threshold Level Incident light level before correction Time Set output switching to D-ON (Dark ON). When power tuning ON / OFF setting is OFF, Smart Tuning is in error or maximum sensitivity tuning is executed, the DPC function is disabled. DPC function does not work depending on the setting. When the Smart Tuning indicator is lit up and the DPC function is set to ON, the DPC function works. If the threshold level must be changed according to the change in the received light intensity, the ATC Function (Active Threshold Control) can be used instead.
(Make the ratio of the received light intensity to the threshold level constant.) The ATC function is enabled when the DPC function is set to ATC in the SET Mode and the Smart Tuning is executed in the Detection Mode. Other restrictions conform to those for the DPC function.
