Well Water Level and TDS SensorA. Obtain the "Well Sensor Printed Circuit Board" and proceed to install the parts as shown in the graphic immediately below.This view has the copper foil on the bottom side. All parts should be installed right on the circuit board without extra lead length.This encourages ruggedness.1. Install the 1K Ohm Resistor (black-brown-red) tight against the circuit board in position R1.2. Install the 2.2K Ohm Resistor (red-red-red) tight against the circuit board in position R2.3. Install the 10K Ohm Resister (black-brown-orange) tight against the circuit board in position R3.4. Install the TLC555 timer snugly on the top of the circuit board. Make sure that Pin #1 is situated as marked below! Pin #1is usually marked by a dimple on the printed circuit that cannot be worn off (like print). Make sure that all 8 pins areprotruding through the circuit board! Bend two pins at opposite corners of the TLC555 to hold it in position until yousolder it.5. Install an insulated jumper wire as shown.6. Install two .1uF Capacitor at C1 and CAdjB. Turn the printed circuit board over, carefully place it in a small vice to keep it secure and solder the components onto theboard. Because of the size of this circuit, it is recommended that a person with electronics experience do this task. Overheating candamage the circuit board or its components. Under heating can cause the solder to bead and make a poor connection. Qualitysoldering equipment makes a world of difference! A site that shows and teaches you how to solder ishttp://www.epemag.wimborne.co.uk/solderpix.htm Once the parts have been properly soldered in position, clip off any excesslead length, as close to the circuit board as possible without clipping the actual soldering itself. Clipping the soldering can breakthe solder bond between the lead and the foil. Leaving the leads too long will cause the unit to short once it is mounted on the backof the receiver.http://www.pbv.thunder-bay.on.ca/WellSensor.html (3 of 12) [1/13/2005 12:45:27 PM]
