4. Troubleshooting & Precautions
Troubleshooting
1.
The unit does not correspond when it is switched on.
Check the fuse at lower right side of the unit and replace it
(AC 250V/5A) if it is damaged or broken.
2. There is leakage in the fuel distributor coupler.
Check the o-rings and replace it if it is damaged or unfitted.
Do not tighten the two riffle screws too tightly; otherwise, it
may cause leakage.
3. The fuel pressure drops slowly.
The fuel pressure can not drop to zero within 1
～
2 minutes,
slightly turn the overflow valve with inner hexagonal spanner
counterclockwise.
4. The buzzer rings continually when there is no fuel pressure.
The machine has fuel-lack warning function and it will ring
when the liquid in the fuel tank is lack, and then
automatically switch off the fuel pump and injectors and
returns to the stop state. Supply the cleanser or test liquid to
stop ringing. At this time, pressing [RUN] key is necessary
to rerun the fuel pump and injectors.
5. Draining the test liquid in glass tube thoroughly requires
pressing the [Drain] key more times.
The solenoid valves will stop automatically after 15 seconds
and it is necessary to drain more times if there is more
liquid.
6. Malfunction code displaying E001.
The malfunction code of E001 is displayed when the
level inside fuel tank is lower than that of the required
level. At this time, the buzzer will ring to remind user
to supply fuel. If this situation appears during running
process, the machine will stop the fuel pump ten
seconds later and make “RUN” indicator is on the
flashing state. After the liquid is up to the required
specification(Press “Drain” key to drain the liquid into
the fuel tank to resume the liquid level if there is lots
of liquid, otherwise, supply the liquid.), the buzzer
will stop ringing. If you press [RUN] key, the machine
will continue to run the interrupted work.
Precautions
1)
Do not place anything on the control panel to prevent
from breaking the measuring cup because it is made
from vulnerable.
2)
Do not disconnect pipe before the system pressure
reaches “0”.
3)
Always ensure that the provided power supply is well
contacted with ground safely.
4)
The unit is designed with warning function. When the
level switch checks the liquid inside the tank less than
the lowest line, the unit will utter the warning sound and
meanwhile stop the fuel pump and injectors
automatically, and then the unit returns to the stop state.
The unit will stop warning until the liquid is supplied
enough, at this time pressing the “RUN” key will run the
unit again.
5)
Clean the control panel in time and Keep the pulse
signal cable away from the liquid.
Warning!
Unauthorized repair may cause the extension of faulty
area of the unit, which will bring trouble to general
repair. Under the state of turning on the power, the
electrical system inside the unit contains the factor
causing danger. Failure to comply with these
instructions could result in death or serious injury.
