GAC 2700-AGRI Grain Analysis Computer
User Guide

Overview

Thank you for purchasing the DICKEY-john ® GAC® 2700-AGRI grain moisture analyzer. The GAC® 2700-AGRI quickly tests grain and automatically calculates moisture content, test weight (bulk density), and temperature of the sample using 149 MHz/UGMA technology.

Safety
Advisory identification and descriptions regarding operation of the GAC® 2700 can be found in the Operator’s Manual.

Declaration of Conformity

The GAC 2700 is in conformity with the provisions of many global directives and regulations. Consult the Operator’s Manual for a complete list.
This product creates an RF signal for measurement purposes and meets the EMC requirements of the United States (FCC 47 CFR, Part 18.109.(c), ISM Class A and ANSI C63.4:2014) and Canada (ICES-001, CISPR11 Group 2, Class A).
The GAC 2700 product series is exempted from the Radio Equipment Directive 2014/53/EU as the RF signal internal to the product is not used for communications. The RF signal power is below the threshold limit to be of concern for EMF Directive 2013/35/EU and therefore no MPE calculation was determined necessary.

Liability
DICKEY-john ® designed the GAC 2700 to measure oilseed and grain moisture content. We rigorously test and calibrate each instrument before it leaves the factory. Use of the instrument in the field, however, is subject to environmental and operating conditions beyond our control. DICKEY-john® disclaims all liability for damages resulting from environmental and operating conditions beyond our control and for any damages that might follow incorrect results due to those environmental or operational conditions. IN NO EVENT SHALL DICKEY-john OR ANY OF ITS AFFILIATES, OFFICERS, DIRECTORS, SUCCESSORS OR ASSIGNS BE LIABLE FOR ANY DAMAGES WHATSOEVER, INCLUDING SPECIAL, INDIRECT, CONSEQUENTIAL OR INCIDENTAL DAMAGES OR DAMAGES FOR LOSS OF PROFITS, REVENUE, USE, OR DATA AS A RESULT OF CLAIMS, REGARDLESS OF THEORY BROUGHT, ARISING OUT OF OR CONNECTED WITH ANY USE OR RELIANCE THE GAC ® 2700.
The operator is responsible for ensuring the results of the testing are as accurate as possible by following approved maintenance procedures on a regular basis, making sure the calibrations are up to date and the latest version is being utilized, by cleaning the instrument and its sensors on a regular and as-needed basis depending on the amount of dust, dirt, and debris encountered in the instrument’s use, by monitoring performance using daily check samples and by adhering to the check procedures set forth in the manual. As with any kind of precision instrument, optimal results depend in part on proper cleaning and maintenance.
For questions concerning these issues, refer to the product warranty, or call your DICKEY-john® representative.
The complete Operator’s Manual is available on our website.

Unpacking

Carefully unpack the GAC ® 2700. Refer to the packing list below to verify that all items are present. Contact DICKEY-john ® if items are missing or broken.
Retain the packaging for use when shipping the instrument; use of other packaging for shipment may result in damage to the instrument.

Packing List

Setting up the GAC® 2700

Setting up the GAC ® 2700 requires the following procedures:

1. Open the carton and remove the Allen wrench from the upper foam insert.

2. Remove the GAC 2700 from the plastic bag. Save the bag, the packaging material, and the carton to use for future transport of the instrument.

3. Ensure the installation location is level using the bubble level at the top of the instrument; adjust the feet if necessary. Unit must be kept level, making sure that there is sufficient clearance between the GAC 2700 and the countertop so that the grain drawer is cleanly inserted into the instrument.

4. Remove the grain drawer and place the unit gently on backside to locate the shipping brackets on the left and right side walls.
   IMPORTANT: Be careful when placing the unit on its backside to avoid damage to the security switch.

5. Loosen and then remove the hex bolt from the bracket on the left side wall.

6. Press down on the bracket to release.

7. Slide the bracket toward the bottom of the instrument.

8. Insert the hex bolt into the operating location hold and tighten using the Allen wrench.

9. Perform the same procedure to the bracket on the right side wall.

10. Once both brackets are tightened to the operating location, place unit upright.

Reverse the process to re-install the brackets for transportation.
This locks the weighing mechanism to prevent damage when moving.

Conducting Grain Analyses

The GAC ® 2700 is designed to provide minimal user interaction to run grain moisture measurements. Upon power up, the GAC® 2700-AGRI will display the Home screen, which is the main screen to conduct grain moisture analysis measurements. From the Home screen:

1. Press the Choose Product button to select the grain or crop that will be analyzed.
2. Enter Sample ID (If desired).
3. Enter Customer ID (If desired).
4. Pour the sample into the Upper Hopper.
5. The START button will change to Green when there is enough grain in the hopper to properly run a sample.
6. Press the START button.

Please consult the operator’s manual on the GAC® 2700-AGRI product page on the DICKEY-john® website for additional information such as loading calibrations, data viewing and other features.

Maintenance

The GAC® 2700 utilizes an RF frequency of 149 MHz to make measurements within the machine. It is not a strong signal strength. If potential interference is determined to originate from the GAC® 2700 simple corrective steps can be taken; move the products further apart from each other, re-orientate the products to each other.
IMPORTANT: It is highly recommended the unit be regularly inspected and cleaned to ensure continued and consistent results.
For optimum performance, extensive cleaning should be performed weekly or more often, as needed, based on surrounding environmental conditions. Factors such as dust, temperature extremes, grain dust, and external humidity vary from location to location. If there are any questions about the cleanliness or instrument performance, contact your local authorized service center.
For customers that require a more extensive cleaning, contact and schedule your instrument for cleaning with your dealer or authorized service center.
Note: The following recommendations are provided as a guideline to maintain a robust and quality operating instrument. It should not be interpreted as an exhaustive maintenance program. Dust and debris may periodically accumulate in areas not specified in this manual. The owner is responsible for ensuring overall equipment cleanliness. If any questions arise regarding the maintenance or performance of the instrument, contact your dealer or local authorized service center.
EXTERNAL CLEANING
The LCD display may require periodic cleaning. Use a commercial cleaner and cloth for glass lenses to remove dust.
CAUTION: Do not apply water, organic solvent or chemicals, such as acid and alkali, to the LCD display.
The GAC® 2700 surface can be cleaned with any cleaner designed for plastic and stainless steel surfaces.
Periodically use a cloth to wipe the grain hopper and the (2) upper grain hopper sensors.

INTERNAL CLEANING
Performing continuous tests can result in material accumulation around the critical internal components and adversely affect the measurement.
Two types of cleaning are recommended on an as needed basis:

• Daily clean
• Extensive clean (see Operator’s Manual for instructions)

DAILY CLEAN METHOD
A daily clean method allows cleaning the cell and door using an automated process. During the cleaning sequence, the hopper door automatically opens.
To start the cleaning process:

1. Select Device Information from the Main Menu.

2. Press .
   – A pop up message will appear with the words “Cleaning Mode is Active”.

3. Remove the grain drawer.

4. Using the supplied brush, manually remove any loose or stuck grain or dust from the measuring cell.

5. Press the CLOSE button to return instrument to normal operation.
   CAUTION: Hands should be clear from inside the instrument before pressing the CLOSE button.

6. Insert grain drawer.
   Press to return to the Home Screen.
