SEE DIAGRAMS ON PAGE 5
1. Tape the drilling template (D‐8) onto the flat location and drill the holes using the sizes indicated on the template. File any burrs from the holes once the drilling is completed.
NOTE: The sloped (leading) edge of the sensor plate must face the
plunger (opposite the direction of the bale movement).
2. Now repeat steps 1 and 2 on the right side of the chamber.
NOTE: Your moisture tester uses 2 moisture sensor pads connected to
the chamber on the left and the right side.
3. Mount the sensor assemblies on the left and right side using the hardware provided.
4. Place the sensor inside the chamber and place bolts (D‐1) through the sensor pad and through the chamber as shown in (Location A). Attach washer (D‐2) and nut (D‐3) to bolt (D‐1) but do not tighten.
5. Place bolts (D‐1) through the sensor and through the chamber as shown in (Location B). Place plastic insulator (D‐5) then the plastic washer (D‐4) over bolt (D‐1). Attach washer (D‐2) and nut (D‐3) to the bolt (D‐1) but do not tighten.
6. Now tighten the nuts and bolts at (Locations A and B).
7. Using one sensor cable per side, place one ring terminal per bolt (D‐1) at (Location B) and then attach washer (D‐2) and nut (D‐3) to the bolts
(D‐1) and then tighten.
8. Before routing the cables through the baler, mark the cable that is attached to the cut side sensor in the bale chamber as you will need to know this later in the installation.
9.
Most balers already have cable routes running from the baler to the hitch area. If this is the case, follow this same route and use any existing cable attachments. Route the sensor cable to the hitch area of the baler so that is does not interfere with any moving parts. Secure the cable with the supplied nylon ties (C‐1).

4.0 OPERATION
UNDERSTANDING HAY CONDITIONS ANDTESTER
READINGS
11
Many variables affect the accuracy of sensor readings. Understanding these variables can help to make use of the sensor readings.
IMPORTANT: Because of the numerous variables, which affect sensor readings, the indicated moisture should not be used as an absolute and quantitative measurement. Sensor readings are, however, very useful for baling and storing hay.
Field conditions: soil moisture, high or low areas, swales, and shaded areas all affect hay moisture within the same field.
Hay varieties: leaf to stem ratio, crop maturity and different cuttings con‐ tribute to widely varying moisture distribution within the hay plants.
Harvest variables: bale density, windrow size and shape, ground moisture, the time of day, hay temperature and overall climate conditions affect hay moisture. High humidity with cloud cover contributes to more variations in hay moisture than a dry, sunny and breezy day.
Some preservatives increase conductivity: Until the preservative is fully absorbed, usually one to two days, the preservative may cause readings to be two to four points above what the same hay without preservative would read.
Bale density: As the bale becomes tighter inside the bale chamber, the moisture readings will appear higher. These higher readings are due to compaction that varies as the bale is being formed.
Each type of baler feeds hay into the bale chamber and forms the bale differently. In general, small rectangular bales are denser toward the bottom or “light” side. Large rectangular bales are densest in their upper corners.
Natural variations within the windrow: Non‐uniform hay moisture is expected in any given windrow. This can occur due to low‐lying areas or drain off channels in a field. The hay that contacts the sensor pads does so randomly. Therefore, pockets of very dry and very wet hay may be detected and those corresponding readings will be displayed.
A poorly prepared windrow can have variations of moisture of up to 20%.
Even a well‐prepared windrow can vary in moisture up to 5%.

6.0 OPERATION OF THE SENSOR
While the bale is being formed in the bale chamber, the 2178 reads and averages several tests and displays these results every two seconds. Typically, moisture readings will vary several percentage points in a single bale.
Windrows are not the same moisture from top to bottom. Usually,they will be wetter at the bottom than in the center due to ground moisture. Windrows can be wetter on the top due to dew or drier on the top because of sun and wind. Typically, low moisture hay varies less than high moisture hay.
Continuous readings from the 2178 and other manufacturer’s meters may be higher than readings from hand‐held hay probe type testers. The 2178 may read a couple of percentage points higher on average than hay probe type testers.
The difference in moisture readings is due to differing densities. Some balers pack the hay more tightly than others do. When a bale is released from the chamber it relaxes and is less dense then when it was initially being formed in the chamber. Tightly packed and dense hay bales appear to be higher in moisture than less tightly and less dense hay bales.
Do not be concerned that these differences exist. Rather, develop a feel for the acceptable range of moisture for baling based upon your testers readings.
Hay moisture can vary considerably from one part of a field to another. If the moisture range displayed by the tester increases above or decreases below your set limits the alarm will sound (unless you have the sound muted or limits are not set). Stop baling and determine the reason for the change in hay moisture. You may want to discontinue bailing in this area of the field.
NOTE: Hay with a moisture percentage above 20% should not be baled or stored without the use of a preservative. Hay with a moisture percentage above 25% should not be baled or stored.
These recommendations have been made to prevent excessive heating of the bale and/or mold growth in the hay, and are recommendations of many agricultural specialists of the agricultural extension offices.

8.0 SERVICE
REPLACING A SENSOR PAD
The sensor pads and contacts can become worn. Contact your Farmscan AG dealer to order replacement sensor pads. See “INSTALL MOISTURE SENSORS” for installation instructions.
CARE, MAINTENANCE AND STORAGE
After each use or after the harvest season, remove the display module (if it is not inside a dry cab) and store in a clean and dry place.
Always use the weatherproof plug covers on the sensor cables to keep moisture and dirt from getting into the electrical contacts.
The stainless steel contacts on the moisture sensors should be kept clean for the best results. Clean with fine steel wool and/or mineral spirits or alcohol.
Dirty contacts can cause lower readings.
Check all nuts and screws on the moisture sensor plates and tighten if necessary. Make sure the sensor pad leading edge is secured flat and tight to the bale chamber wall.
