UOR-MOD950T1106Wireless Monitor Transmitter

INSTALLATION AND OPERATION INSTRUCTIONS The Wireless Monitor Receiver (950R) automatically records sensor readings received from Field Transmitters (950T) for collection and display on a computer. Each Field Transmitter can read up to four (4) Watermark soil moisture sensors, temperature sensors or Irrometer Model RSU (4-20mA transducer) sensors. The Receiver unit can also read a direct input from a switch closure sensor or rain gauge. SENSOR INSTALLATION Watermark soil moisture sensors must be “conditioned” prior to installation. The sensors should be soaked to saturation and then dried fully, twice, and then soaked to saturation again prior to installation. This “conditioning” of the sensors ensures quick response to changing soil moisture conditions. If a sensor is only soaked and then installed, several irrigation cycles must pass before the sensor will respond accurately. Soak the sensors in a bucket of water for several hours to saturate them. Hang them up overnight to dry sufficiently. After “conditioning” they are ready for installation. Sensors MUST be installed in an active portion of the root zone of the plant to be monitored, either vertically or up to a 45° angle. Bore a 7/8” (22mm) diameter access hole to the desired depth, then insert the sensor. Be careful to ensure a snug fit between the sensor and the surrounding soil. Then backfill the hole firmly. The access hole can be made by pounding a 7/8” (22mm) diameter bar (or ½” IPS pipe) to the desired depth, then extracting the bar, being careful not to disturb the soil surrounding the borehole. With hard or rocky soil, a larger diameter hole can be made with a soil auger. Mix the auger cuttings with water to create a slurry and pour into the borehole. Then insert the sensor into the hole. Once the slurry dries, the sensor will have been “grouted” in to ensure good contact with the soil. The sensor can be attached to ½” class 315 PVC pipe with a PVC to ABS cement. The pipe becomes a conduit to protect the sensor wires. Also, this makes the sensor easier to push into the access hole and remove, if desired. The top of this pipe section should be capped or plugged so surface water does not travel down to the sensor. Drill a small hole in the side of the pipe just above the sensor to allow water to drain away if it becomes trapped in the pipe. To measure soil temperature and compensate the accompanying Watermark sensors on the same Field Transmitter, the temperature sensor should be installed in the soil near a representative soil moisture sensor. Only one temperature sensor can be used per Field Transmitter. Bore a 1/2” (13mm) hole in the soil and insert the sensor. Then backfill the hole. #89 TROUBLESHOOTING Please reference the suggestions below, look in the Help section of WaterGraph or contact Irrometer for further assistance. No Display: Check battery, replace if <7.2 Volts. Try RESET, see below. Unusual readings: The following are possible readings that may be displayed instead of a soil moisture, temperature or switch position: DRY-meaning the resistance is so high that there must be an open wiring connection on a Watemark or a low temperature reading (frozen) on a temperature sensor, check for broken wires. SHORT- meaning the resistance is so low that the circuit must be shorted on a Watermark, or off scale on a temperature sensor, check for shorts. No reading reported for too long: Sensor may have lost contact with the soil. Re-install sensor, being sure to establish good soil contact. Communication may be poor from that location. Transmission can be checked from the Field Transmitter to the Receiver by pressing the small button in the middle of the transmitter circuit board. Each press of this button should register another reading on the counter in the display of the Receiver. Relocate or elevate antenna as necessary for better transmission. Soft RESET: Use the end of a paper clip or other small object to press the RESET button located underneath the small hole labeled RESET on the faceplate. Hard RESET: Disconnect the battery. Press and hold the RESET button down for at least 5 seconds. Then re-insert the battery. Firmware upgrading: Using the “Update Datalogger” command in the “Tools” menu in WaterGraph, select the new firmware version (.hex format) and press “Open.” If the upload process is interrupted, then Monitor will be locked up and it’s display will stay on “Uploading.” If this happens, use the “Recover Monitor Update” command in the “Tools” menu to finish the upload process.
