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 - 7. Agrónic’ and check that there
is voltage in the output part and that the mother-
board is correctly configured.
• 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. Parameters - 8. 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.
Parameters - 8. Installer - 5. Various - Digital Meter
Sensor’ (Various).
An input is not read from the base
• Go to ‘Consult - 7. Agrónic’ and check that there
is voltage in the output part and that the mother-
board 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 - 7.
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.
