• Locations with rapid temperature changes, leading to dew condensation

• Locations with corrosive gases (especially sulde gas, ammonia, etc.) or ammable gases.

• Locations with vibration or shock directly. (Vibration and shock may cause output relay malfunction.)

• Locations in contact with water, oil, chemicals, steam or hot water. (If the equipment gets wet, there is a risk of

electric shock or re, so have it inspected by Fuji distributor.)

• Locations with high concentrations of atmospheric dust, salt or iron particles.

• Locations with large inductive interference, resulting in static electricity, magnetic elds or noise

• Locations in direct sunlight.

• Locations that build up heat from radiant heat sources, etc.

Recommended site conditions

• A place where the ambient humidity during operaion is between 45 to 85% RH.

About EMC standard

This equipment is a class A , for industrial locations, equipment. Do not use this equipment in domestic

establishment, such as residential areas, or it may cause radio interference. If you use this equipment in

domestic locations, take adequate measures on the outside of the equipment to reduce radio interference.

Under the requirement of EMC standard, the maximum length of external cable including a sensor to be

connected to this equipment is 30 m. Do not connect the sensor longer than 30 m.

Panel mounting

Insert the controller unit into the panel cutout from the front, and then put the mounting bracket from the rear.

The mounting bracket should be pushed in until the controller is securely xed to the panel. If there is a slight

gap remaining, gently tighten the two screws until the gap disappears. (Make sure not to over tighten the screws,

as doing so may result in the mounting bracket separating from the stopper.)

The front of this equipment is waterproof in compliance with NEMA-4X standards (IP66- equivalent). To effect

waterproof, the included packing is shall be attached between the controller and the panel according to the

guidelines below. (Incorrect attachment may cause the equipment to lose its waterproof capabilities.)

(1) As shown in Fig. 1, insert to the panel after attaching the packing to the equipment case.

(2) As shown in Fig. 2, tighten the screws of the mouthing bracket so that no gaps can remain between the

equipment face, the packing and the panels. Once nished, conrm that there are no changes in shape such

Packing

If the panel does not have enough strength, gaps may develop between the packing and the panel to lose

waterproong capabilities.

In order to aid heat dissipation, do not block the sides of the equipment.

Do not block the air vents on the top and bottom of the case.

Wiring

For thermocouple input, use the designated compensation lead; for RTD input, use wires with small lead wire

resistance and without any resistance difference among the three wires.

To avoid noise conductor effects, input signal wires should be separated from electric power lines or load lines.

Input signal wire and output signal wire should be separated each other. And both should be shield wire.

If there is a lot of noise from the power source, adding an insulation transducer and using a noise lter is

recommended. Always attach a noise lter to a panel that is grounded securely, and keep the wiring between

the noise lter output side and the measuring equipment power terminal wiring to a minimum length. Please do

not attach fuses and switches, etc. to the noise lter output wiring; otherwise the lter’s effectiveness will be

decreased.

Twisting the power wires is effective when connecting the wires. (The shorter the pitch of the twist, the more

effective the connection is against noise.)

Operation preparation time is required for the contact output when power is turned on. If using it as a signal to an

external interlock circuit, please couple it with a delayed relay.

Concerning the output relay, connecting the maximum rated load will shorten the product’s life; so please attach

an auxiliary relay. If the output operation frequency is high, selecting a SSR drive output type is recommended.

[Proportionate cycles] Relay output: 30 seconds or more, SSR drive output:

1 second or more

When inductive loads such as magnetic opening/closing equipment, etc. as relay output equipment are connected,

use of a surge absorber is recommended in order to protect the contacts against opening/closing surges and to

ensure long-term use.

Recommended specication for the surge absorber

200V 470V

Attachment position: between the relay control output contacts.

Operation

The alarm function does not work properly when an error takes place unless the settings are made correctly.

Always verify its setting before operation.

If the input wiring breaks, the display will read “UUUU” or “LLLL”. When replacing the sensor, always turn the

power OFF.

Others

Please do not wipe the equipment with organic solvents such as alcohol or benzene, etc. If wiping is necessary,

use a neutral cleaning agent.

Do not use mobile phones near this equipment (within 50 cm). Otherwise a malfunction may result.
