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.

AGRETO LoadCounter II M

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
© AGRETO electronics GmbH page:10
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.

7Assembly
Only start with the assembly once you have clarified whether a change in the
configuration is necessary for your application. Please read the chapter
"Configuration" before.
7.1 Positioning the sensor and the magnet
The mounting location of the sensor and the magnet must be chosen in such a
way that the magnet generates pulses in the sensor during the application
process of a load or transport process. The magnet must move past the front
end of the sensor at a distance of 5 to 8 mm.
Example scraper floor shaft on a manure spreader:
The magnet is attached to one of the scraper floor shafts. If there is no suitable
option here, the magnet can also be attached to the side of a chain wheel or a
flange. The sensor is attached to a frame part.
Example PTO shaft on a manure spreader:
The magnet is mounted on the trailer's PTO shaft stub, the flat bar for the
sensor on a frame part. For this type of mounting, the optionally available
magnetic ring can be used instead of the magnet.
Example dumper:
The magnet and the sensor are mounted at one point so that contact is made
at least once during lifting and once during lowering.
Example sliding wall on a push-off trailer:
The magnet and the sensor are mounted at one point in such a way that
contact is made at least once during pushing off of the load. A second contact
is made when the sliding wall is returned.

7.2 Mounting the sensor and the magnet
Mount a fastening part for the sensor (for example a piece of flat iron) with a
hole of 12.5 mm on the machine and fasten the sensor in the hole.
The sensor must protrude at least 10 mm from the bracket.
The sensor tip must be 5 to 8 mm away from the magnet.
A 5.5 mm hole or an M5 thread is required for the fastening the screw of the
magnet.
The red side of the magnet must point towards the red sensor tip.
Under no circumstances the sensor should touch the magnet when the
machine is working, otherwise it will be irreparably damaged.

7.3 Positioning of the meter
Choose a location on the machine that is as protected as possible and still
accessible, this also results in the routing of the sensor cable. The position of
the meter is not relevant for operation.
7.4 Fixing the mounting plate
On delivery, the meter is mounted on the
mounting plate. Disassemble the meter from
the mounting plate.
Hold the mounting plate in the desired
position to the desired mounting position.
Use the mounting plate as a template and
mark the 2 holes with a pin.
Hit one notch each with a grain.
Drill the 2 holes with a 4.2 mm diameter drill.
Deburr the 2 holes.
Use a M5 screw tap to cut a thread in each hole.
Use the 2 M5x25 allen screws and the 2 aluminum washers and screw the
base plate to the machine. Note that the sealing surface of the base plate
is pointing towards the meter.

AGRETO LoadCounter II M

7.5 Fastening the counter
Place the counter on the base plate.
Use the 4 allen screws M5x8. Two of them
have a small hole for the seal wire, use these
two on the side where you want to attach the
seal.
First, pull slightly down all 4 screws, and then
tighten every screw again so that the
housing is evenly pressed against the
mounting plate.
7.6 Attaching the seal
Thread the seal wire through the holes in the
two screws.
Thread both ends of the wire through a hole
in the seal.
Slide the seal as close as possible tot he
meter and at the same time tighten the wire.
Close the seal.
If the hole of one oft he screws is not accessible,
you can also drill a small hole in the housing bar
between the two screws and pull through the seal
wire here.

operation for reading is not provided.
The symbol X indicates that the displayed
number is the sum of the loads.
8.2 Reading the hours (operating mode 5B)
In operating mode 5B, the sum of the counted loads and the sum of the
counted hours are displayed alternately at intervals of 5 seconds. The symbol h
indicates that the number displayed is the sum of the hours.
If the colon is visible as a separator, it is
hours and minutes.
If the comma is visible as a delimiter, it is
decimal with 2 decimal places.
The display is updated every 5 seconds.

8.3 Symbols on the display
Below the main display there are various
icons for displaying additional information.
The arrow to the right means that the pause time is running now.
The wavy line means that the counter is currently detecting movement
or vibration and is in counting mode.
The round arrow means that pulses are counted now.
The n lights up in the setting mode when entering the number of pulses.
The x means that the displaying of the loads is active.
The h means that the displaying of the hours is active.
The s lights up in the setting mode when a parameter value is expected in
seconds.
The crossed-out battery icon lights when the batteries are low and
you need to replace them.

9Maintenance and cleaning
The Counter basically does not require ongoing maintenance.
If the display is dirty, clean it for reading.
If the battery symbol is lit, replace the batteries.
10 Troubleshooting
10.1 The battery symbol lights up
The batteries need to be replaced, follow these steps:
Remove the seal and the seal wire.
Remove the housing and remove the meter.
Remove the old batteries and dispose them properly.
Insert 2 new AAA batteries into the device in the specified direction.
Mount the counter again on the mounting plate.
Seal the device again with a new seal wire and a new seal.
10.2 Loads are not counted completely
The parameters may not be set correctly for your application.
Set the pause time only high enough to be reached safely with each
load.
Only set the number of pulses high enough to ensure that they are
reached with every load.
Check the installation situation of the sensor, possibly move the sensor
closer to the magnet.

AGRETO LoadCounter II M

10.3 Too many loads are counted
The parameters may not be set correctly for your application.
If possible, set the pause time higher. However, always orientate yourself
on a short transport process.
Set the number of pulses higher, but they must still be reached safely
with every load.
10.4 Operating hours are not counted completely
The movements or vibrations on the machine are probably relatively low, so that
the necessary intensity for the count is not reached.
Set the parameter SENS down so that the counter triggers even with minor
movements.
To hold longer periods of rest during operation, set the parameter hOLd
upwards.
10.5 Too many operating hours are counted
Perhaps the machine is exposed to light movements at standstill, which are
recorded as operating hours.
Set the parameter SENS upwards so that the counter only triggers for
larger movements
To prevent idle phases from being counted during operation, set the hOLd
parameter down.
