Certain Precautions on Specifications and Use

1. Suitability of Use. Omron Companies shall not be responsible for conformity
with any standards, codes or regulations which apply to the combination of the
Product in the Buyer’s application or use of the Product. At Buyer’s request,
Omron will provide applicable third party certification documents identifying
ratings and limitations of use which apply to the Product. This information by
itself is not sufficient for a complete determination of the suitability of the Prod­uct in combination with the end product, machine, system, or other application
or use. Buyer shall be solely responsible for determining appropriateness of
the particular Product with respect to Buyer’s application, product or system.
Buyer shall take application responsibility in all cases but the following is a
non-exhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) Use in consumer products or any use in significant quantities.
(iii) Energy control systems, combustion systems, railroad systems, aviation
systems, medical equipment, amusement machines, vehicles, safety equip­ment, and installations subject to separate industry or government regulations.
(iv) Systems, machines and equipment that could present a risk to life or prop­erty. Please know and observe all prohibitions of use applicable to this Prod­uct.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT
ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO

ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP­ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE
OVERALL EQUIPMENT OR SYSTEM.

2. Programmable Products.

test conditions, and the user must correlate it to actual application require­ments. Actual performance is subject to the Omron’s Warranty and Limitations
of Liability.

4. Change in Specifications
changed at any time based on improvements and other reasons. It is our prac­tice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifica­tions of the Product may be changed without any notice. When in doubt, spe­cial part numbers may be assigned to fix or establish key specifications for
your application. Please consult with your Omron’s representative at any time
to confirm actual specifications of purchased Product.

The

PC is the part of the Control System that directly controls the manufacturing
process. According to the program stored in its memory, the PC accepts data
from the input devices connected to it, and uses this data to monitor the con­trolled system. When the program calls for some action to take place, the PC
sends data to the output devices connected to it, to cause that action to take

When

connecting TTL circuits to transistor Output Units, it is necessary to

nect

a pull-up resistor and a CMOS IC between the two. This is because of the
residual voltage left on the transistor output after the output turns OFF.

When

an inductive load is connected to an I/O Unit, it is necessary to connect a
surge suppressor or diode in parallel with the load as shown below. This is so
that the back EMF generated by the load will be absorbed.

To replace a fuse, follow the steps below:

1. Turn OFF the power to the PC.

2. Remove the fuse holder by turning it approximately 50° counterclockwise
with a standard screwdriver.

3. Remove the fuse from the holder.

4. Insert a new fuse.

5. Reattach the fuse holder by turning it approximately 50° clockwise with a
standard screwdriver.

To replace a fuse, follow the steps below. Use only UL/CSA certified replace­ment fuses.
