Adjustment and Operation

Connect load before turning the power supply on.

Do not short-circuit the load.
Although an error is displayed when the product load is short circuited, excess current may cause damage to the
product.

Do not press the setting buttons with a sharp pointed object.
This may damage the setting buttons.

Supply the power when there is no flow.

If using the product to detect very small flow rates, warm up the product for 10 to 15 minutes first.
There will be a drift on the display or the analogue output of approximate

2 to 3% immediately after the power
supply is turn on, within 10 minutes.

Check regulators and flow adjustment valves before introducing the fluid.
If pressure or flow rate beyond the specified range are applied to the sensor, the sensor unit may be damaged.

Do not attempt to insert or pull the flow rate sensor or its connector when the power is on.

The output is off for 3 seconds after power is supplied.

Use settings suitable for the operating conditions.
Incorrect settings can cause operational failure.
(Refer to page
19 "Outline of setting")

During the initial setting and any subsequent flow rate setting, the product will switch the output
according to the existing settings until the changes are complete.
Confirm the output has no adverse effect on machinery and equipment before setting.
Stop the control system before setting if necessary.

Maintenance

Perform regular maintenance and inspections.
There is a risk of unexpected malfunction of components due to the malfunction of equipment and machinery.

Turn off the power supply, stop the supplied air, exhaust the residual pressure and verify the release of
air before performing maintenance.
There is a risk of unexpected malfunction.

Perform drainage regularly.
If condensate enters the outside, it can cause operating failure of pneumatic equipment.

Do not use solvents such as benzene, thinner etc. to clean the product.
They could damage the surface of the body and erase the markings on the body.
Use a soft cloth to remove stains.
For heavy stains, use a cloth lightly dampened with diluted neutral detergent, then wipe up any residue with a dry
cloth.
