  • Page 13: Introduction

    1. Introduction The ET107 is an automated weather station designed for irrigation scheduling in turf grass and commercial agriculture applications. A properly programmed station calculates potential evapotranspiration (ETo), which is the amount of water lost from the soil due to evaporation and plant transpiration.

  • Page 14: Precautions

    Save the caps for shipping or storing the sensors. Campbell Scientific recommends routing the cable of the optional soil sensors in conduit, especially if the soil is rocky or rodents are present. The cables for these sensors do NOT have an armored outer jacket.

    The data logger does not draw power from the lithium battery while it is powered by a 12 VDC supply. In an ET107 stored at room temperature, the lithium battery should last approximately 10 years (less at temperature extremes). Where the ET107 is powered most or all of the time, the lithium cell should last much longer.

    6. Cycle the power to the data logger by switching the PS150 power supply to OFF then to ON, or by disconnecting and reconnecting the battery plug. The keypad should power up and the Campbell Scientific logo and text should appear on the display. 7. Call Campbell Scientific if still no response.

    10 x 12 inch enclosure The PS24 Power Supply is typically used when a solar-powered ET107 transmits data using a wireless communication option. However, the PS24 can be used for any situation where a larger capacity battery is desirable.

    FIGURE C-3. Enclosure supply kit C.2 PS24 installation CAUTION: The PS24 is purposely shipped without the battery mounted in its bracket. Do not install the battery until instructed to do so. 1. Place the top enclosure bracket on the pole at approximately 10 m (3 ft) above the bottom of the pole.

Connect one wire per CHG terminal block. 12. If the charging source is a solar panel, remove the blanket or box from the solar panel once it’s wired into the CH150, PS100 or PS150 regulator.
  • Page 114 NOTE: The power cable that carries the regulated 12 VDC power from the regulator in the external enclosure to the ET107 station enclosure has a two-pin connector on one end and tinned wires on the other. 13. Toggle the power switch on the regulator (CH100, PS100, CH150, or PS150) to the OFF position.
  • Page 115 NOTE: Since the power coming into the enclosure is regulated power coming from the external enclosure, the wiring inside the ET107 station enclosure needs to be different than the standard wiring. 17. If this is a retrofit, inside of the ET station enclosure, wires come through the enclosure wall from the POWER connector on the back of the station that used to be wired into the charge ports of the PS100 or PS150.
