... Refer to the QT102-ISG datasheet for details (see www.qprox.com/downloads). • Insert the battery provided into the battery holder on the E102 board. Ensure that the battery has the correct orientation (negative (-) side to board) or the E102 will not work. • Touch KEY and the LED will light. After the Auto-off Delay is reached (actual time is dependent on Voltage level, Ct and Rt tolerances), the LED will switch off. Default setting: User-set Auto-Off Delay (J3 Pins 1 & ...

... Active High: Output: (LK2) The E102 can be used to connect a User electrode to the QT102 (using EXT and GND pads: The value of Cs may require changing. Large pads either side of Cs are available for fitting leaded capacitors in parallel). The E102 can also connect to a User output (using OUT and GND pads). ...

... Troubleshooting: Problem E102 does not work Inaccurate timeout values Unexpected timeout delay Timeout delay not x1 or x24, as expected LED unexpectedly on Potential Solution If using a battery, check that the negative (-) side is facing the board. Check/replace battery, check connections. If using an external power supply, check that the correct connections have been made ...
