Product specifications

The direct current power supply used should be UL approved as follows.

Circuit (Class 2) of maximum 30 Vrms (42.4 V peak) or less, with UL1310 Class 2 power supply unit or UL1585

Class 2 transformer.

The product is a UL approved product only if it has a mark on the body.

Use the specified voltage.

Otherwise failure or malfunction can result.

Insufficient supply voltage may not drive a load due to a voltage drop inside the product.

Verify the operating voltage of the load before use.

Do not exceed the specified maximum allowable load.

Otherwise it can cause damage or shorten the lifetime of the product.

Data stored by the product is not deleted, even if the power supply is cut off.

(Writing time: 1000000 cycles, Data duration: 20 years after power off.)

Reserve a space for maintenance.

Allow sufficient space for maintenance when designing the system.

●Product handling

Installation

Tighten to the specified tightening torque.

If the tightening torque is exceeded the mounting screws and brackets may damaged.

If the tightening torque is insufficient, the product may be displaced and the mounting screws may come loose

(Refer to page 13 "Mounting and Installation".)

Do not apply excessive stress to the product when it is panel mounted

Otherwise damage to the product and disconnection from the panel mount can result.

Ensure that the FG terminal is connected to ground when using a commercially available switch-mode

power supply.

Do not drop, hit or apply excessive shock to the product.

Otherwise damage to the internal parts can result, causing malfunction.

Do not pull the lead wire forcefully, not lift the product by pulling the lead wire. (Tensile force 49 N or less)

Hold the product body when handling, to prevent damage, failure or malfunction

Never mount a product in a location that will be used as a foothold.

The product may be damaged if excessive force is applied by stepping or climbing onto it.

Wiring

Do not pull the lead wires.

In particular, never lift a product equipped with fitting and piping by holding the lead wires.

Otherwise damage to the internal parts can result, causing malfunction or disconnection of the connector.

Avoid repeatedly bending or stretching the lead wire, or placing heavy loads on it

Repeated bending stress or tensile stress can cause damage to the sheath, or breakage of the wires.

If the lead wire can move, fix it near the body of the product.

The recommended bend radius of the lead wire is 6 times the outside diameter of the sheath, or 33 times the

outside diameter of the wire insulation material, whichever is larger.

Replace any damaged lead wire with a new one.

Wire correctly.

Incorrect wiring can damage the product.

Do not perform wiring while the power is on.

Otherwise damage to the internal parts can result, causing malfunction.

Do not route wires and cables together with power or high voltage cables.

Otherwise the product can malfunction due to interference or noise and surge voltage from power and high voltage

cables.

Confirm proper insulation of wiring.

Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess

voltage or current being applied to the product, causing damage.

Keep wiring as short as possible to prevent interference from electromagnetic noise and surge voltage.

Do not use a cable longer than 30 m.

Wire the DC (-) line (blue) as close as possible to the power supply.

When analogue output is used, install a noise filter (line noise filter, ferrite element, etc.) between the

switch-mode power supply and this product.

Environment

Do not use the product in area that is exposed to corrosive gases, chemicals, sea water, water or steam.

Otherwise failure or malfunction can result.

Do not use in a place where the product could be splashed by oil or chemicals.

If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent, even

for a short time, it may be adversely affected (damage, malfunction, or hardening of the lead wires)

Do not use in an area where electrical surges are generated.

If there is equipment generates large electrical surges (solenoid type lifter, high frequency induction furnace, motor,

etc.) close to the product, damage or failure of the internal circuit may occur. Take measures against the surge

sources, and prevent the wires from coming into close contact.

Do not use a load which generates a surge voltage.

When a surge-generating load such as a relay or solenoid is driven directly, use a product with a built-in surge

absorbing element.

The product is CE marked, but not immune to lightning strikes. Take measures against lightning strikes

in the system.

Do not use the product in areas that are exposed to vibration or impact.

Otherwise failure or malfunction can result.

Do not use the product in the presence of a magnetic field.

This may lead to the malfunction of the product.

Prevent foreign matter such as wire debris from entering the product.

Otherwise failure or malfunction can result.

Do not use the product in areas subject to large temperature cycle.

Heating/cooling cycles other than ordinary changes in temperature can adversely affect the internal structure of the

product

Do not expose the product to direct sunlight.

If using in a location directly exposed to sunlight, use a suitable protective cover.

Otherwise failure or malfunction can result.

Keep within the operating temperatures range.

Operating temperature range is 0 to 50 °C.

Operation below the minimum temperature limit may cause damage or operation failure due to frozen moisture in

the fluid or air.

Avoid sudden temperature changes even within the specified temperature range.

Do not operate close to a heat source, or in a location exposed to radiant heat.

Otherwise malfunction can result.

No.PF※※-OMJ0018-F

Adjustment and Operation

Connect load before turning on the power.

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.

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 "Flow 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.

Do not touch the LCD during operation.

The display can vary due to static electricity.

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.

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.
