The diamond ring saw TR40 is controlled by the water-cooled frequency converter FU6U.
Operate the frequency converter only with a type B residual current circuit breaker.
Please wait approximately 20 s before the machine is started after switching on the main switch.
In the event of a fault or power failure, switch off the main switch and check the cause (fuse). Before
switching on again, switch of the main switch for 60s.
Always keep the connectors clean and tight and secure. Water or moisture in the
connector may cause serious damage to the electronics. Do not use water jet or high
pressure cleaners to clean the converter and the machine. Max. Water pressure 4 bar.
Status and error outputs are showed to the user via an LED attached to the frequency converter.
Status display
If there is a status change the green LED on the side of the converter flashes/shines. The number of pulses
after a longer break allows the assignation of the status according to following chart:
Status code
Meaning
green off
Frequency converter without
voltage supply
green
Intermediate circuit is charged - Wait
flashing
Frequency converter waits for

Service intervall exceeded
green on
Frequency converter ready
Failure display
If a failure occurs the red LED on the side of the converter flashes/shines. The number of pulses after a
longer break allows the assignation of the status according to following chart:
Status code
Meaning
red
Low voltage
permanent on
red 1x pulse
Over temperature motor - Increase water flow (cooling of motor or converter is too
red 2x pulse
Over temperature
frequency converter
red 4x pulse
Overcurrent
red 5x pulse

Grooves of the saw blade
worn.
Incorrect saw blade for the
material to be machined.
Too little water.

Measure
- Switch on main switch
- Use adapter calbe type FU06543
- Check supply cable (cable interrupted)
- Check mains voltage (fuse)
- Connect machine
- Check connectors of machine and converter for
dirt and damages
- Bring converter to service station
- Converter can be used
Measure
- Increase wire cross section (extension cord)
- Check supply cable (cable interrupted)
- Use a generator with more power
low; water temperature is too high)
- Check hose connection
Never use waste water for cooling!
- motor stops, motor has been used in the overload range
- Check motor cable and plug connection for damages
(short circuit)
- Reduce machine load, motor is operated in the overload
range
Replace saw blade.
Consult your dealer for advice.
Improve the water supply of the
blade.
Make a straight cut as guide.
Contact your dealer.
Increase water cooling.
