8 TROUBLESHOOTING
These are the most common problems and we attempt to provide the solution to facilitate the
installation process.
An output is not activated
Go to ‘Consult - 9. Agrónic’ and check that there is
voltage in the output part and that the motherboard
is correctly configured (see section 6.7 of the user
manual).
Unit with relay base. If there is no voltage at the
outputs (V.Out: no) the 12 Vdc/24 Vac supply of the
R- R+ terminals may be failing (check with a tester)
or one of the valves is crossed (disconnect the output
terminal).
Unit with latch base. Check that the type of latch valve
and the trip voltage are correct in ‘Function - 4. Param-
eters - 10. Installer - 5. Various’. If none of the valves
work, open the unit and check whether there are any
burned components on the base plate.
To carry out tests, the output can be activated directly
from ‘Function - 2. Manual - 9. Outputs’.
The meter accumulates more volume than
the real one
First make sure that the meter cable is away from any
AC cables.
When the meter relay changes state, it can cause
‘bounces’ in the line, which can cause the Agrónic to
accumulate extra pulses. To avoid this, increase the
time of the back-torque filter in ‘Function - 4. Param-
eters - 10. Installer - 5. Various - Digital Meter Sensor’
(see section 5.8).
An input is not read from the base
Go to ‘Consult - 9. Agrónic’ and check that there is
voltage in the output part and that the motherboard
is correctly configured (see section 6.7 of the user
manual). If there is no voltage at the outputs (V.Out:
no) the inputs will not work, check the voltage of the
R- R+. If there is voltage (V.Out.: yes) go to ‘Consult - 9.
Agrónic’ and press the ‘ 1 ’ key to access the internal
query. The status of the 6 digital inputs (DI) appears
at the bottom of the screen. Use a cable to directly
connect the CD terminals and the input to be tested
(D1 to D6). A 1 (connected cable) or a 0 (unconnected
cable) must appear on the screen.
