Distribution Center or DMC’s factory in Mason City, Iowa (See the listings on page 15.) OPERATION The Combine Calc-U-Dri II control box is designed to be mounted to the ceiling of a combine cab. Always refer to the owners manual for installation and operating infor- mation.

After a delay of approximately six (6) seconds, the “AVG ON” light will turn on. This light indicates that the Combine Calc-U-Dri II moisture reading is being used to update both the short and long averages. If sufficient grain is not present to keep the average switch covered, the “AVG ON”...
CONTROL BOX INSTALLATION The Combine Calc-U-Dri II control box is designed to be mounted to the ceiling of the combine cab or any convenient location. Select a location in the cab and check the area above for any hoses, tubes or electrical wiring that could be dam- aged by the control box mounting screws.

CONTROL BOX INSTALLATION (continued) For installations where the control box is to be mounted to a flexible surface, it may be desireable to use a back-up plate or brackets to stiffen the mounting surface. Use the cover of the control box as a template to mark the location of the six (6) mounting holes on the back-up plate or brackets.
CONTROL BOX INSTALLATION (continued) Feed the power supply wires through the same grommet and route them to a convenient power source in the cab. Make sure that one end of the red wire is connected to the positive (+) side of a power source and the other end to terminal number five.

SENSOR INSTALLATION (continued) Mark the flighting that sweeps over the sensor hole and disassemble the auger tube from the flighting. Locate the marks made on the flighting above the sensor hole and weld the flighting to the auger shaft starting 3/8” beyond each end of the marks. Cut approximately six and one-half inches (6-1/2”) of flighting out between the welds and smooth out any rough edges on the flighting ends and on the auger shaft.

SENSOR INSTALLATION (continued) Use a self drilling screw to attach the ground strap to the auger tube 90 degrees up from the sensor. See Photo F. Make sure that the sensor is oriented properly in the tube. Note the direction of the grain flowing over the sensor blade.
AVERAGING SWITCH INSTALLATION The averaging switch should be mounted in the boot housing of the clean grain auger. so that grain being thrown hits and accumulates on the yellow face of the switch. See Diagrams 3 - 6. The switch must be horizontal and facing oncoming grain.

AVERAGING SWITCH INSTALLATION (continued) Drill a 15/32” hole through the housing next to the bracket and insert a grommet. Run the cable from the switch through this grommet. Secure the cable to the bracket using a plastic wire tie ran through the two small holes. Make sure the cable is protected from oncoming grain by placing the cable and grommet directly behind the bracket.
SAMPLING PROCEDURE !!CAUTION!! *Always stop the combine (travel, thresher and unload auger) before getting a sample. Ideally, stop the combine engine! *Be careful when climbing into the grain hopper. Follow the combine manufacturer’s recommendations. The following procedure should be done prior to the hopper auger being covered with grain and should be done when the moisture of the grain is at the level of which you are most concerned: If the meter is changing rapidly, it is possible to have a sample that is either...

COMBINE CALC-U-DRI OFFSET RECOMMENDATIONS The Combine Calc-U-Dri can be used with various grains by calibrating the moisture offset. After determining an offset value for a particular grain and grain condition, log the offset value on the following chart for future reference. A few grains and approximate offset values are already listed to assist with your initial calibration.
“off” to control the auger motor in the combine sampler. The sensor housing is designed for a DMC Calc-U-Dri moisture sensor which is held in place with 2 latches. The sensor ground wire should be attached to the flange of the housing with a #10 self- tapping screw.
