Remedy
The lamp goes
off and the
compressor for
refrigeration
stops.
The fluctuation of the power supply
voltage is too large.
- Install a power supply transformer or use a different power
supply to provide appropriate voltage.
- The fluctuation of the power supply voltage should be kept
/-10% of the rated voltage.
- Refer to “5.2 Reset of protective equipment” and reset the
protective circuit.
(When the facility
water is not
flowing, the
compressor for
refrigeration has
stopped with the
lamp lit up.)
Water-cooled condenser is dirty.
- Clean the water-cooled condenser.
Foreign matter has accumulated
on the strainer, and the facility
water flow rate has decreased.
- Conduct maintenance of the strainer once a month, and
clean the foreign matter that has accumulated.
The fluctuation of the power supply
voltage is too large.
- Install a power supply transformer or use a different power
supply to provide appropriate voltage.
- The fluctuation of the power supply voltage should be kept
/-10% of the rated voltage.
The built-in overload relay of the
compressor for refrigeration has
started.
- Check the product was not restarted within 3 minutes after
being stopped.
(When the facility
water is flowing,
and the
compressor for
refrigeration has
stopped with the
lamp lit up.)
Water-cooled condenser is dirty.
- Clean the water-cooled condenser.
The facility water temperature is
high.
- Reduce the facility water temperature as much as
possible.(Reconsider the cooling tower.)
Foreign matter has accumulated
on the strainer, and the facility
water flow rate has decreased.
- Conduct maintenance of the strainer once a month, and
clean the foreign matter that has accumulated.
The compressed air temperature
is too high.
- Improve the ventilation in the location where the air
compressor is installed, or decrease the ambient
temperature to allow the discharge air temperature of the
air compressor to go down.
- Install an aftercooler after the air compressor to reduce the
temperature.
Moisture is
generated at the
downstream of
the compressed
air line.
The bypass valve is open.
- Be sure to fully close the bypass valve.
Condensate is not drained from
the auto drain.
- Check the draining piping is not used in an upward direction
nor bent.
- Check the auto drain.
- Check the ball valve is open.
The piping of a different system
without an air dryer joins the piping
after the product.
- Install another air dryer (this product) in that system.
- Keep the two systems separate.
The compressed
air pressure is
too large.
The valves at the inlet and outlet of
the piping of the product are not
fully opened.
- Be sure to fully open the valves at the inlet and outlet of the
product.
The air filter, etc. installed in the
compressed air piping has got
clogged.
- Replace the element of the air filter.
(Follow the Operation Manual of the equipment.)
The operating
time accumulator
display is not
flashing or off.
The built-in battery has reached
the end of its life.
- Refer to “4.2.4 Maintenance of operating time accumulator”
and replace the battery.
