- This alarm is generated when seed shut-off does not
operate.
- Check the cable, switch and connection of the mag-
netic clutch in the seed box. An LED on the seed box
switch lights when the clutch receives current. The
clutch should then stop the feed roller. If the alarm is
generated although the LED lights, a likely cause is a
defective magnetic clutch.
- Check whether the intermediate cable between the
Control Station and Workstation is connected. Inspect
the condition of the cable and connectors. The green
indicator lamp on the Workstation shows that voltage
is present, however, the lamp could light even though
the intermediate cable is partially damaged.
- Workstation 1 receives a lower voltage than 11 V. In-
spect the connections and connectors of the interme-
diate cable. The function of the hydraulic valves, etc.
may cease to work.
- Workstation 2 receives a lower voltage than 11 V. In-
spect the connections and connectors of the interme-
diate cable. The function of the hydraulic valves, etc.
may cease to work.
- Check the cable, connectors and connections of the
sensor.
- Check that the sensor is not dirty or damp. Dry the
sensor with a dry cloth.
- The sensor may be defective.
- Check the rpm sensor of the drive wheel transmission.
- Check the cable, connector and connection of the sen-
sor.
- Is the hydraulic oil flow sufficient? Does the seed out-
put fan start?
- Check whether the seed boxes can rotate by hand.
- Check the cable, connector and connection of the sen-
sor.
- Check the operation of the sensor.
