INTRODUCTION

Thank you for purchasing the Fuji Electric temperature/process
controller. All of these controllers are PID Autotune controllers that
employ Fuji Electric’s patented fuzzy logic algorithms.

It is a fully programmable temperature/process controller incor­porating many user-friendly features. The following easy-to-use
instructions are intended to help you understand, set up, effectively
operate, and achieve optimal performance from your controller. When
programmed and operated within the guidelines set up for them in this
manual, your controller will give you years of precise, reliable control.
If needed, we will provide free technical support throughout the life of
the controller.

The first section of this manual details the specifications and
general description for the PXV3 controller. The second section will
cover the PXW controller, followed by a detailed description of the
programming parameters, which are common to both the controllers.
Several appendices describe some of the controlling techniques.
Finally, a Quick Reference guide gives a listing of all the parameters
and their default values.

SAFETY PRECAUTIONS

Before using this product, the user is requested to read the follow­ing precautions carefully to ensure safety. The safety requirements
are classified as either “warning” or “caution” according to the
following explanations:

Warning

Wiring

1. If there is danger of serious accident resulting from a failure or
defect in this unit, provide the unit with an appropriate external
protective circuit to prevent an accident.

2. The unit is normally supplied without a power switch or a fuse.
Use power switch and fuse as required (Rating of the fuse: 250V,
1A)

Power supply

1. Be sure to use the rated power supply voltage to protect the unit
against damage and to prevent failure.

2. Keep the power off until all of the wiring is completed so that
electric shock and trouble with the unit can be prevented.

General

1. Never attempt to disassemble, modify, or repair this unit.

Tampering with the unit may result in malfunction, electric
shock, or fire.

2. Do not use the unit in combustible or explosive gaseous atmos-

pheres.

Caution

Installation

1. Avoid installing the unit in places where:

• the ambient temperature may reach beyond the range of -10 to
50°C (14 to 122°F) while in operation

• the ambient humidity may reach higher than 90% RH while in
operation

• a change in the ambient temperature is so rapid as to cause
condensation

• corrosive gases (sulfide and ammonia gas, in particular) or
combustible gases are emitted

• the unit is subject to vibration or shock

• the unit is likely to come in contact with water, oil, chemicals,
steam, or vapor

• the unit is exposed to dust, salt, or air containing iron particles

• the unit is subject to interference with static electricity, mag­netism, or noise

• the unit is exposed to direct sunlight

• heat may be accumulated due to radiation

Maintenance

1. Do not use organic solvents such as alcohol or benzene to wipe
this unit. Use a neutral detergent.

2. Three-year warranty is guaranteed only if the unit is properly
used.

NEMA 4X Integrity

The front side of this instrument conforms to NEMA 4X. To ensure the
waterproofness between the instrument and the panel, use the gasket
that is provided with the unit according to the installation procedure
described below.

1. Install the gasket over the enclosure and insert the unit into the
panel as shown in Figure 1.

2. Slide the mounting bracket and tighten the screws as shown in
Figure 2.

Caution: After the mounting bracket is installed, check the gasket for

displacement and detachment as shown in Figure 3.

FRONT PANEL OPERATION

The PXV3 controller programming menu consists of three blocks—
PRIMARY (SETPOINT) MENU, SECONDARY (SYSTEM) MENU, and
FACTORY PRESET MENU. At power up the controller will be in the
operational mode, and process variable (PV) will be displayed. This is
the variable that is being controlled, and it is not programmable. When
setting the parameters, turn off the power to the load (operating equip­ment) to ensure safety. Since it takes 30 minutes for the unit to stabilize
in terms of temperature, all measurements should be carried out at
least 30 minutes after the power is turned on. Option-related features
are displayed only when the options are provided.

Viewing and Setting Parameters

• The data is automatically registered in 3 seconds after the setting.
It can also be registered by pressing the SEL key.

INSTALLATION

NEMA 4X Integrity

The front side of this instrument conforms to NEMA 4X. To ensure the
waterproofness between the instrument and the panel, use the gasket
that is provided with the unit according to the installation procedure
described below.

How to install the unit

For PXW-5/7/9, install the two metal brackets, one on the top and the
other on the bottom, and tighten the screws to a torque of about 14.7N­cm (1.5kg-cm). For PXW4, install the unit in the panel as shown below,
and tighten the screws on the mounting bracket until the unit is secure.
Make sure there is no space between the front side of the unit and the
gasket, and between the gasket and the panel.
