PRODUCT CHARACTERISTIC

OMRON shall not be responsible for conformity with any sta-
ndards,codes, or regulations that apply to the combination of
the products in the customer’s application or use of the prod-
uct.
Take all necessary steps to determine the suitability of the pr-
oduct for the systems,machines, and equipment with which it
will be used.
Know and observe all prohibitions of use applicable to this
product.

NEVER USE THE PRODUCTS FOR AN APPLICATION INVOLVI-
NG SERIOUS RISK TO LIFE OR PROPERTY WITHOUT ENSUR-
ING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO
ADDRESS THE RISKS, AND THAT THE OMRON PRODUCT IS
PROPERLY RATED ADN INSTALLED FOR THE INTENDED USE
WITHIN THE OVERALL EQUIPMENT OR SYSTEM.

)

Use this product within the rated load

and power supply.
2) Make sure that the rated voltage is
attained at the moment of turning ON
the power using a switch or relay contact.
If the voltage is applied gradually, the
power may not be reset or output
malfunctions may occur.
3) Use the output relays within their life
expectancy.

Electrical life of relay 100,000

operations (250VAC 3A,resistive
load)

Machinery life of relay 10,000,000

operations
4) Operating environment
Do not use the product in places where
explosive or flammable gases may be
present.
5) Load power supply
Make sure that the load power supply is
within the rating.
6) Handling
Never disassemble, modify or repair the
product.

Indicates a potentially hazardous situation which, if not avoided,is likely to result
in minor or moderate injury or property damage. Read this manual carefully bef-
ore using the product.

1) The product is designed for indoor use only. Do not use the product outdoors or in any of the
following locations.

Places directly subject to heat radiated from heating equipment.

Places subject to splashing water, oil or chemicals.

Places subject to direct sunlight.

Places subject to dust or corrosive gas (in particular, sulfide gas and ammonia gas.)

Places subject to intense temperature change.

Places subject to icing and condensation.

Places subject to vibration and large shocks.

Places subject to explosive or flammable gases.

2) Use/store within the rated temperature and humidity ranges. Provide forced-cooling if required.

3) Be sure to wire properly with correct polarity of terminals.

4) Do not wire the terminals which are not used. Check noise influense carefully before wiring.

5) Allow as much space as possible between the controller and devices that generate a powerful high
frequency, surge or much static electricity. Separate the high-voltage or large-current power lines
from other lines, and avoid parallel or common wiring with the power lines when you are wiring to
the terminals.

6) A switch or circuit breaker should be provided close to this unit.
The switch or circuit breaker should be within easy reach of the operator, and must be marked as
a disconnecting means for this unit.

7) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.

8) Make sure the proper product is specified for the application.

9) Store at the specified temperature, If the products has been stored at a temperature of less than
-10

，

allow the products to stand at room temperature for at least 3 hours before use.

Do not touch the terminals at least within 60 seconds, after turning the power OFF.
Doing so many occasionally result in minor injury due to electric shock.

Do not touch the terminals while power is being supplied. Doing so may occasionally
result in minor injury due to electric shock.

Do not use the product where subject to flammable or explosive gas.
Otherwise, minor injury from explosion may occasionally occur.

Never disassemble, modify or repair the product or touch any of the internal parts.
Minor electric shock, fire, or malfunction may occasionally occur.

Tighten the terminal screws at the specified torque. Loose screws may occasionally
result in fire.

Do not allow pieces of metal, wire clippings, or fine metallic shavings or filings from
installation to enter the product. Doing so many occasionally result in electric shock,
fire, or malfunction.

If the output relays are used past their life expectancy, contact fusing or burning may
occasionally occur. Always consider the application conditions and use the output rela-
ys within their rated load and electrical life expectancy.
The life expectancy of output relays varies considerably with the output load and swit-
ching conditions.

HOW TO CHANGE OPERATION MODE

Connection of contact signal inputs

HOW TO CHANGE TIME UNIT AND RATED TIME

Operate the push buttons of the thumbwheel switch, located
at the leftmost position on the front panel, to set the operation
mode, Eight operation modes (A,B,C,D,E,F,G, and H ) are
selectable and the selected operation mode is displayed in the
operation mode display window.

as shown in the following diagram.
The input signal from the solid-state circuit
is applied when output transistor Tr turns
ON. In terms of signal voltage, the signal is
input when it goes from high level to low
level. Again, the residual voltage should be
1V max. when the transistor is ON. As the
current output from the timer to Tr is
approximately 0.1 mA, this connection is
possible provided the residual voltage is
kept to the 1V maximum.

For each signal input contact, use a gold-
plated contact of high contact reliability.
Be sure that these input signals satisfy
the following requirements: a resistance

1V max. when the contact makes.

NOTES:
Excepting the wirings for power supply
circuit, avoid the laying of input signal
wires in parallel or in the same conduit
with high-tension or power lines. It is
recommended to use shielded wires or
wiring with independent metal conduits
for the shortest possible distance.

For signal input, use a transistor of open collector type
with characteristics:

From a solid-state circuit (proximity switch, photoelectric
switch, or the like) with the rated power supply voltage
ranging from 6 to 30 VDC, input signals can also be
applied by other than the open collector type transistor

Operation the pushbuttons of the rightmost thumbwheel switch
to select the desired time unit. Seven time units (0.1s, s, 0.1m,
m, 0.1h, h, or 10h) are selectable and the selected time unit
is displayed in the time unit display window.
The desired rated time is specified by operating the 3 thumb-
wheel switches in the middle of the front panel. The range of
a rated time is 001 to 999 for each time unit.

ERROR MESSAGE

TIMING CHARTS(OPERATION MODES)

CONFORMANCE TO EN/IEC STANDARDS

HOW TO CHANGE THE PRESET VALUE

The bar display will flash if an error occurs in the built-in IC.
Reset the power supply to clear the error.

NOTES: 1.The minimun signal input time is 0.05 sec.
2.The minimum resetting time is 0.5 sec .
3.Note that output will be generated in C, D, E, G, or H mode
even if rated time is set to 000. No output will be generated
in A, B, or F mode.

This is a class A product
In residential areas it may cause radio interference,in which
case the user may be required to take adequate measures to
reduce interference.

A constant read-in system is used. This enables changing the
set value of the timer even when the timer is operating. The
elapsed time display will also change accordingly if the timer’s
set value is changed during timer operation.

Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse
affects on the performance and functions of the product. Not doing so may occasionally result in
unexpected events.
