201 Measured value after taring too high
(zero + 5000 grams)
202 The measured value is not stable
during taring.
203 Measured value after taring too low
(zero - 5000 grams)
402 The feed sensor detects feed (feed
indicator on) when the discharge
hatch is opened.
404 Discharge hatch did not open
405 Discharge hatch did not close.
500 Not a valid silo number.
5xx Transport supply from silo xx has
stagnated.
xx = silo number user (is set on the control computer).
Attention NEVER FORGET TO SWITCH AN ALARM "ON" AGAIN after switching it off, e.g. to solve a
problem, since this may have harmful effects on people, animals, equipment or goods.

The system will try to finish the active weighing cycle.
The active weighing cycle will be aborted (reset) if the

CALIBRATING FEED HOPPER
1. Remove inspection cover (right side feed weigher).
2. Check that the transport lock is loose (unscrewed all the way down).
3. Restore the inspection cover. Check that the inspection cover is closed (the green "SWITCH" led is on).
4. Empty the weighing hopper by opening and closing the discharge hatch once (set the front switch to the
"OPEN" position for a couple of seconds and then set it to "CLOSE"). Check if hopper is empty.
5. Go to the installer's mode.
6. Select line 4.02 and change the "0" to "1" (1 = calibrate empty weighing hopper).
7. Select line 4.03 and change the "0" to "1". Calibration is started; after calibrating, parameters 4.02 and
4.03 automatically change to "0".
8. Place a reference weight of, for example, 20 kg in the weighing hopper.
9. Select line 4.08 and check that the reference weight in the weighing hopper (20 kg) equals the reference
weight setting on the display (20000 = 20 kg).
10. Select line 4.02 and change the "0" to "2" (2 = calibrate hopper "full" with reference weight in hopper).
11. Select line 4.03 and change the "0" to "1". Calibration is started; after calibrating, parameters 4.02 and
4.03 automatically change to "0".
12. Select line 4.00 (current weighing hopper content).
13. Remove the reference weights from the weighing hopper one by one while checking that the value on the
display equals the weight remaining in the weighing hopper.
14. Check that all weights have been removed.
15. Enter parameters 4.05 and 4.07 on the installer codes list.
16. Set the front switch to "AUTOM." (automatic).
17. Exit the installer's mode.
Extra feed dropped after the discharge hatch closed.
Feed has caked or something is stuck in the weighing
hopper.
Ambient vibrations affect the result of the measurement
(the receptacle touches the chassis of the weighing
hopper while unloading the weighing hopper or switching
the auger on/off).
The feed sensor is covered by feed at the moment when
the unloading valve opens.
Discharge hatch opened with manual operation.
Faulty feed sensor or feed sensor not connected.
Hatch not opened/closed after 10 seconds although it was
given a drive signal to open/close it.
The component is not in the selected silo.
There is still no feed supply after 60 seconds.
Stagnation in supply transport or silo xx is empty.
