Instructions for remote control WK600-D
and
WK600-D2
4. Troubleshooting
Warning: Make sure that the machine is switched
off and the power is switched off before trou-
bleshooting the machine or possibly repairing it.
Problem 1:
The machine is switched on but has
poor airflow and the suction capacity is enormously
reduced.
Cause:
The air supply may be blocked, or a foreign
object may be stuck in the exhaust arm or airway.
The filter may be clogged and consequently block
-
ed, resulting in the machine sounding an alarm.
Remedy:
Switch off the machine and disconnect
the power. Open the lid and check that no foreign
object has been sucked up and stuck in the air in-
take. Check if the valves are blocked. If the suction
capacity is still poor, this indicates that the filter is
clogged and needs to be replaced.
Problem 2:
The machine shuts down automatically
at start-up and even after restart.
Cause:
The air flow in the machine is uneven due
to. too high resistance through the filter. This
results in the fans running at maximum power and
the starting current becoming too high, then the
overheating protection switches on and the machi-
ne is switched off.
Remedy:
Switch off the machine, disconnect the
power supply and open the cover. Check if any
foreign object is blocking the air intakes. Set the
fan speed to the lowest level and then restart the
machine. It should work normally again. If the
above action did not solve the problem, contact our
workshop.
Explanation of the function of the buttons
ON / OFF button (Power Switch)
When the ON / OFF button is pressed, an orange
light comes on and the machine starts. The next
time you press the same button, the orange light
goes out and the machine switches off.
(Note: For extended periods without use, turn off
the main power switch and unplug it.)
Increasing Fan Flow
While the machine is on, increase the speed with
the push of a button, the value shown on the dis-
play will increase by 10. When the maximum value
100 is displayed, the machine runs at maximum
speed.
Decreasing Air Flow
While the machine is switched on, you reduce the
speed with the push of a button, the value shown
on the display will decrease by 10. When the value
10 is displayed, the machine runs at the lowest
speed.
Timer (Shutdown Timer, Timer Set)
While the machine is on, press the clock button and
the display will show HXXX, use the fan speed but-
tons to adjust the time. H symbolizes hour and XXX
corresponds to the number of hours. Maximum va-
lue for timer is 300 hours and minimum value is 1
hour. After setting the timer to the desired number
of hours for shutdown, confirm the setting by pres
-
sing the button with the clock symbol again. The
display will then show the set timer time "HXXX".
For example. "H005" which means that the machi-
ne will automatically shut down after 5 hours.
OK / Setting
When the machine's alarm / alarm lamp flashes
and the alarm signal beeps, press this button to
switch off. In normal mode, use this button to dis-
play the accumulated operating time.
Locking Control Panel
While the machine is on, one keystroke on the
"Locking Control Panel" disables all buttons on
the control panel. The buttons are unlocked when
another button is pressed on the "Locking Control
Panel", or when the machine is restarted via the
main switch.
