6Configuration
6.1 Selection of the operating mode
The AGRETO LoadCounter II M has 2 operating modes. In the first mode, only
the amount of loads are counted, in the second mode additionally the working
hours are counted.
First, decide which operating mode is suitable to your application, set the
required settings if necessary, and then mount the counter on your machine!

6.2 Operating Keys
The control buttons are located inside the device and accessible from the back
with the mounting plate removed.
To change settings, look at the buttons and
then turn the device with the display to the
front to read the display.

6.3 Setting the operating mode
On delivery, the operating mode 5A is preset.
To change the operating mode, press and hold the "M" button for 3 seconds.
After releasing the key, the display briefly shows "MOdE" and then the current
setting of the operating mode appears.
Change to the desired operating mode with the "+" or "-" buttons.
The "M" key (or if you wait 10 seconds) will save the selection and exit the menu.
Please note: Changing the operating mode will reset all totals to 0.

6.4 Process of detecting a load
The loads are recorded by the reed sensor, which must receive a certain
number of impulses, and a pause time, which must then pass at least. If both
conditions are met, a load is counted.
The minimum number of pulses ensures that even interruptions in the spreading
process, and thus exceeding the break time, do not lead to an additional load
(e.g. break while driving, longer drive at the headland, drive to the next field ...)
The pause time, in turn, ensures that no additional load is counted even if the
scraper floor is running for a long time or a trailer is tipped up several times.
As soon as more than 100 impulses are required for a load, individual impulses
that occur during the break are not recorded (for example if the PTO shaft
moves a little while driving on the road).
This logic ensures the greatest possible security when recording the number of
loads.
6.5 Setting the parameters
For the correct recording of the loads, the parameters for the number of pulses
and the pause time may have to be adjusted. In mode 5B, the parameters for
time recording are also available.
To open the parameter menu, briefly press the "M" key. The first parameter that
is relevant for the set operating mode appears on the display.
The name of the parameter is displayed for two seconds, then the set value
appears.
Use the "+" or "-" keys to change the value of the parameter. The value of the
parameters IMP and dELA can be increased or decreased by 100 by pressing
the button for more than a second.
Use the "M" key to change to the next parameter, the set value is saved. After
the last parameter, the first parameter is displayed again.
To exit the menu, press and hold the "M" button for three seconds, or simply
wait 10 seconds without pressing a button.

Parameter IMP - number of pulses
This parameter indicates how many impulses the device must at least receive
from the sensor in order to count a load. A pulse always arises when the
magnet turns or moves past the sensor.
1 = lowest number that can be set
10 = default setting
4000 = largest number that can be set
The number of pulses must be set for the application.
Example scraper floor shaft on the manure spreader:
Count or calculate the number of revolutions of the shaft that are necessary for
a complete discharge (e.g .: 10 to 20). This number is set in the device. You can
deduct a small safety reserve so that every load is counted safely. The set feed
rate has no effect here.
Example PTO shaft on manure spreader:
Since the number of impulses is very high here, it is best to determine them
over time. Let the PTO run at 540 revolutions per minute, set the highest feed
rate and measure the time it takes for a complete emptying. If the process takes
1.5 minutes, for example, then multiply 540 x 1.5 = 810. After deducting a small
safety margin, set 750 pulses, for example.
Example dumper:
Since the magnet delivers an impulse once when lifting and once when
lowering, you have to set 2 as the number of impulses.
Example sliding wall on a push-off trailer:
Since the magnet delivers an impulse once when pushing the sliding wall and
once when returning it, you have to set 2 as the number of pulses.

Parameter dELA - (Delay) pause time
The pause time is the minimum time that must pass before a load can be
counted. It starts to run when the sensor has delivered the set number of pulses
and no longer delivers any pulses (for example, if the shaft stops rotating)
1 = lowest adjustable time in seconds
420 = default setting (7 minutes)
9999 = largest adjustable time in seconds
The pause time should include the travel time from the unloading point to the
loading point (for example from the field to the farm), the time for the loading
process itself and the travel time from the loading point to the unloading point
(for example from the farm to the field).
The time should be measured in such a way that even a load without a long
travel time is recorded. It is best to simply add up the time required for a
loading process and 2 times the travel time to the nearest unloading location
and set approx. 90% of this time.
Parameter SENS - Sensitivity (operating mode 5B)
This parameter determines from which intensity of a movement the count is
triggered, ie how strong the vibration or movement must be. The higher the
value, the stronger the movement must be to trigger or continue the count.
0 = highest sensitivity (counts even on very small movements)
2 = a running internal combustion engine is already detected
4 = default
10 = lowest sensitivity (only counts for extreme movements)
The parameter SENS is related to the parameter hoLd, since a movement must
always have a certain intensity and must be present for a certain period of time
in order to trigger the summation.
Parameter hoLd –Holding time (operating mode 5B)
In idle mode, this parameter determines the time in seconds that the counter
waits after a first move to actually start the totalization permanently. If there is
another movement within the set time (which is strong enough), the time from
the first movement is added up and the counter is in counting mode. If there is

AGRETO LoadCounter II M

no further movement within the set time, the counting is stopped and the sum is
reset to the initial value.
1 = summation starts immediately after the first movement
20 = default
100 = summation is started after 100 seconds
In counting mode, this parameter determines the length of a rest period in
seconds, during which the count continues without interruption. If another
movement follows within the set time (which is strong enough), the complete
time is added up, including the rest phase. If the rest period lasts longer than
the set time, the count stops and the sum is reset to the value at the beginning
of the rest phase. The meter is now in idle mode.
1 = summation is stopped immediately at the end of the movement
20 = default
100 = A rest period of up to 100 seconds is counted
Parameter UnIt - Display format (operating mode 5B)
This parameter determines the format of the hour display.
00:59 = default setting, display in hours and minutes (hhhh:mm)
00,99 = display in hours with 2 decimal places (hhhh,hh)
By default, the display is in hours and minutes, and the colon is used as the
separator.
If necessary, you can change the display to decimal hours, here the comma is
used as separator.
6.6 Zeroing the counter
To reset the counter, press and hold all 3 buttons together for 3 seconds. When
released, all totals are set to 0.
