ECL202 AND ECL202e The ECL202e is identical to the ECL202 except that the ECL202e resolution is never better than 0.2 µm. For this reason, the ECL202e does not require an export license. This manual will only refer to the ECL202, but all instructions apply to the ECL202e except where noted. -
Page 4: Front Panel Controls And Indicators
Green Green Green Blue ECL202 NEAR The LED Range Indicator is independent of the output voltage and not affected by the Offset button. Shifting the output voltage by using the Offset button may allow an apparently valid output voltage to exist while the probe is out of range. When the Near or Far LED is red, the probe is out of range and the output voltage is not a reliable indication of the target position. -
Page 5: Setpoint Button
Setpoint Button The ECL202 provides an adjustable setpoint at which a switched output activates. The output switch closes when the output voltage is more positive (larger gap) than the user-adjusted setpoint. Pressing the Setpoint button will set the threshold voltage to the current output voltage. -
Page 6: Maximizing Performance
Multiple sensor orders are shipped with the interconnect board in place and the drivers are pinned together as one unit. It is critical that each ECL202 be connected to the probe indicated on the “USE PROBE CAUTION S/N” label on the front of each ECL202. -

¹Actual values depend on probe and range and are listed on the calibration certificate shipped with the product. Contact Lion Precision for replacement certificates. ²In High EMI environments (10 V/m), output noise levels may rise to 30 mV causing resolution to be reduced to 0.3%. - Page 10 Parameter Specification Notes U3 Probe ±0.04% F.S./°C U5 Probe ±0.1% F.S./°C U8 Probe U12 Probe Nonferrous U18 Probe ±0.04% F.S./°C U25 Probe U38 Probe Over 15°C to U50 Probe 50°C Temperature Coefficient Driver temperature U3 Probe ±0.08% F.S./°C range U5 Probe ±0.1% F.S./°C U8 Probe U12 Probe...
