INTRODUCTION
Thank you for upgrading your scale indicator for use with the grain cart
AutoLog feature. With this feature, the rotation counter sensor allows for the
indicator to count the number of revolutions of the PTO shaft which in turn
allows the unit to “Automatically Log” Field, ID and weight information without
the need for pressing the Start/Stop Button. In this way, one can be ensured
that data will never be lost due to forgetting to press the Start/Stop button and
data will be more accurately recorded. Through this installation manual, you
will be guided through the steps necessary to install the rotation counter
sensor and cabling for the AutoLog feature on your grain cart.

TESTING THE SYSTEM
1. With power applied, the Rotation Counter Status LED as shown in
Figure 3 will turn “On” when it senses the steel target.
2. If sensor LED is constantly “On”, move sensor from target slightly. The
target should light sensor LED only when PTO is spinning or when
target is directly in line with sensor as shown in Figure 3.
3. Once the PTO has gone above the set minimum RPM speed
(RSSMIN) and tolerance RPM speed (RSSTOL) for the desired start
time delay (RSSTDY), you should expect to see the indicator display
“START”.
4. When the PTO has gone below the RSSMIN for the RSSTDY, you
should see, “STOP” and “PRINT”. Your Field ID, Time Stamp and
Weight information should be recorded.
WARNING
Failure to install this system properly could result in sensor and equipment
damage. Please read this document thoroughly before engaging PTO.
WARNING
Failure to keep sensor clear of dirt and debris could result in sensor and
equipment damage.
WARNING
The installation diagrams show safety shields removed in order to show
additional details. Never operate equipment without safety shields in place.
Adding the target to a rotating shaft may require additional shielding and is not
provided. Consult your original equipment manufacturer.
