Troubleshooting:
?
The turbine does not start when the START key is pressed.
Answer:
The magnet at the stop sensor is not in position or the sensor or sensor cable is damaged.
Stop sensor: The mark must be on when the magnet is in position and off when the magnet is removed. See Menu 3.
A damaged cable can be assembled in an epoxy moulded assembly or with shrinkable tubing and glue.
However, since the sensors are more sensitive than telephone cables in the ground, cable assembly must be seen as an emergency solution.
If a pressostat is installed, the water must be pressurized. The mark must be on when there is pressure.
?
No numbers in the display.
Answer:
Battery disconnected. Fuse inside the box may have blown. The fuse will blow if the battery is wrongly connected.
An additional fuse is available from the factory on a single fuse terminal on the circuit board.
Fuse 5A. Battery voltage 12V. See Menu 2.
?
Clock is set to 00:00
Answer:
If the power is interrupted, the clock is reset. The end time is then the number of hours and minutes until irrigation is complete.
See page 15 for setting the clock.
?
The number of metres is not counted correctly and the speed is not correct.
Answer:
If the speed is measured with a roller running on the hose, check whether the roller is running smoothly or if it is not installed properly on the hose.
You will also need to check that the roller sensor with cable is functioning properly. See Menu 3 Speed sensor.
The 2 marks must light up in the following order from the right during unwinding: The first one turns on, then the second one turns on, the first
one turns off, then the second one turns off. During rewind, this happens in reverse order.
?
Only half or perhaps 2/3 of the actual length has been counted.
Answer:
The stop bracket with magnet for the stop sensor may have jumped, so the magnet has been removed temporarily from the stop sensor. This will
reset the counter. Or a hose turn has been so loose that it has impacted the miswinding bracket.
This is usually the same as the impact on the stop bracket and has the same result.
Even if the metres are not saved in the memory, irrigation will still continue at the selected speed and the machine will stop as normal. However,
there will be deviations if the speed is measured on a gear disc and the calculation is based on formulas entered in MACHINE DATA. This is because
the electronics do not know which hose layer the machine is running on. Finally, the metres can be entered manually.
