Pressure Setting
Warning
(1) Set within the display pressure range of the scale plate. If it is set outside of the pressure display
range, it may cause operation failure or setting deviation.
Caution
(1) Use a screwdriver of a size suitable for the groove of the adjustment screw.
(2) The switch setting display indicator shows the pressure when the switch is turned off.
(3) Pressure when the switch is ON is the pressure in when hysteresis is added to the indicated
pressure.
(4) The pressure displayed by the indicator is a guideline. Measure the pressure correctly using a
pressure gauge.
Maintenance
Warning
(1) Maintenance should be performed according to the procedure indicated in the Operation Manual.
If handled improperly, malfunction and damage of machinery or equipment may occur.
(2) Perform regular inspections and confirm normal operation.
Otherwise it may be impossible to guarantee safety due to unexpected malfunction or erroneous
operation.
(3) Do not touch the internal wiring during energizing.
There is a risk of electric shock by contact with the product that is energized.
Turn OFF the power supply before wiring.
(4) Make sure to wear safety goggles for regular maintenance.
(5) Make sure to confirm that no pressure is applied to this product and that electrical cables are
disconnected before performing maintenance.
(6) After maintenance, confirm that the product satisfies specific functions and no external leakage
occurs before operating it.
(7) Maintenance work
If handled improperly, compressed air can be dangerous. Maintenance should be performed by a
knowledgeable and experienced person.
(8) Drain flushing
Compressed air containing too much condensate leads to malfunction.
Air filters installed on
airlines, etc., requires periodic discharge of the drain to make sure that the drain does not flow
downstream. Check the filter element periodically and replace it with a new one if necessary.
(9) Removal of equipment, and supply/exhaust of compressed air.
When components are removed, first confirm that measures are in place to prevent workpieces
from dropping, run-away equipment, etc. Then, cut off the supply pressure and electric power, and
exhaust all compressed air from the system using the residual pressure release function. When
re-starting the product, make sure that the liquid sudden blow prevention is applied.
(10) Caution for use in an interlock system If using in an interlock circuit, provide a double interlock in
vessel of failure, and perform regular checks to confirm proper operation.
(11) When installing the products, allow access for maintenance. It may not be possible to perform
maintenance checks if there is not enough space.
