15.0 CHECK POINTS BEFORE TROUBLE SHOOTING
.
In this chapter we have some general check points that have to be examined first if something
is wrong with the machine. In chapter 17.0 we have a more detailed trouble shooting.
There are three basic assumptions that have to be fulfilled if the machine shall function
properly:
1.
The oil pressure from tractor should be 180 bar.
2.
The return flow of oil has to be as low as possible, max. 10 bar counter pressure.
3.
Enough electric power to all functions.
15.1
OIL PRESSURE.
In order to control that the oil pressure into the machine is high enough, there has to be applied
a gauge to the oil pressure hose, for example on the quick coupler.
If the pressure is less than 180 bar, there will be less power for the functions. The first place you
check this is on the ROLLERS OUT / IN.
OIL Flow.
The oil flow that the tractor delivers must be
minimum 15 liters/minute,
but it is recommended
that it is 25 liters/minute. (Max. allowed oil flow is 90 liters/minute).
REMEMBER! Large oil flow = Valves get hot. (Small oil tank = insufficient cooling).
15.2
RETURN PRESSURE.
The return pressure can be too high. With high return pressure the machine's functions will get
less power. High return pressure means also that you need more power to operate the valves.
MAX. ALLOWED COUNTER PRESSURE IS 10 BAR.
If you are in doubt about the counter pressure, arrange a "free return" directly to the tank.
15.3
ELECTRIC POWER.
It is important to check that all function get enough electric power. If not, some, or all functions
may not operate correctly.
Is the battery voltage high enough?
The control box display indicates the voltage being supplied if this is too low.
If the voltage falls below 10 volts this is treated as an interruption of the power supply and all
functions stop.
Are the cables correctly connected to the battery?
Follow directions in chapter 4.9 and 13.0.
Is the connection between battery cable and control unit OK?
Clean off the poles and check that the plug comes correct in place.
Is the connection between control unit and machine OK?
Change contacts if any doubt about the condition.
Is the fuse on the battery cable OK?
There are two 10A fuses.
DO NOT INCREASE THIS FUSE SIZE.
PLEASE CONTACT YOUR DEALER IF YOU ARE IN DOUBT.
(Remember always to give your dealer the serial number and production year of your
machine when contacting dealer and when ordering spare parts).
