| Remote AUTOSET Input: | Opto-isolated momentary sinking input (10 milliamps) |
| Response Time | MEP45WL – Light/Dark = 45µs Repeatability = 13µsMEP – Light/Dark = 175µs |
| Push Button Control: | AUTOSETManual AdjustmentsSet status of 5 options: 5) Lock, 4) Output Invert, and Pulse Stretchers 3) 10ms, 2) 25ms, and 1) 50ms |
| Hysteresis: | Set for high resolution … less than one bar on the contrast indicator |
| Light Immunity: | Responds to sensor’s pulsed modulated light source … immune to most ambient light and strobes, including indirect sunlight |
| Diagnostic Indicators: | 5-LED Bargraph functions in one of two modes:1. Contrast Indicator… Displays scaled reading of sensor’s response to contrasting light levels (light to dark)2. Status Indicator…Displays status of five selectable optionsRed LED output indicator … Illuminates when the sensor’s output transistors are “ON” NOTE: If Output LED flashes, a short circuit condition existsAmber LED…Illuminates when in the options select modeYellow LED…Illuminates when Lock feature is activated |
| OFFSET/EDR® Adjustment: | Sets initial level on CONTRAST INDICATOR in relation to mid-scale switch point of 5 – functions as sensitivity adjustmentControls Enhanced Dynamic Range circuit (EDR®) which functions to avoid saturation |
