■ Input Connection
Reset Input Connection
Connection of the reset input contact or an open collector transistor between terminals A and C (between terminals C and G for models with
backup power for memory protection) permits the timer to reset when contact is made or the transistor turns ON. Use of a high-reliability goldplated contact is recommended for the reset input. For the reset input transistor, select the one satisfying the following electrical ratings:
VCEO = 20 V min.
IC = 50 mA min.
ICEO (leakage current) = 0.5 µA max.
VCE(sat) (residual voltage) = 2 V max.

Gate Input Connection
Connection of the gate input contact or an open collector transistor between terminals A and D (between terminals C and E for models with
backup power for memory protection) permits the timer to stop operation while contact is made or the transistor turns ON. Use of a high-reliability
gold-plated contact is recommended for the gate input. For the gate input transistor, select the one satisfying the following electrical ratings:
VCEO = 20 V min.
IC = 50 mA min.
ICEO (leakage current) = 0.1 mA max.
VCE(sat) (residual voltage) = 2 V max.
Use a gate input contact with a short bounce time because the contact bounce time causes an error in the operate time of the timer for a period
equalling the bounce time.

■ Protective Cover
Note: 1. The Hard Protective Cover prevents the set count value
from being altered due to accidental contact with the pushtype thumbwheel switch.
2. The Soft Protective Cover allows the set value to be set by
depressing the thumbwheel switches through it.
It may be, however, difficult to make setting changes of the
Timer with the Y92A-48B Protective Cover attached, which
must be taken into consideration before using the Y92A-48B
Protective Cover.
The Protective Cover shields the front panel, particularly the count
value setting section from dust, dirt and water, and prevent
malfunctioning of the Timer due to static electricity.

Safety Precautions
● Be sure to read the precautions for all Timers in the website at: http://www.ia.omron.com/.
Warning Indications
CAUTION
Precautions for Safe Use
Indicates a potentially hazardous
situation which, if not avoided, may
result in minor or moderate injury or in
property damage.
Precautions for
Safe Use
Supplementary comments on what to
do or avoid doing, to use the product
safely.
Precautions for
Correct Use
Supplementary comments on what to
do or avoid doing, to prevent failure to
operate, malfunction or undesirable
effect on product performance.
Meaning of Product Safety Symbols
Used to warn of the risk of electric shock under
specific conditions.
Used for general prohibitions for which there is no
specific symbol.
Used for general mandatory action precautions
for which there is no specified symbol.
CAUTION
Do not touch the terminals while power is being
supplied. Doing so many 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.
The life expectancy of output relays varies considerably
with the output load and switching conditions. Always
consider the application conditions and use the output
relays within their rated load and electrical life
expectancy. If the output relays are used past their life
expectancy, contact fusing or burning may occasionally
occur. Also, never exceed the rated load current. When
using a heater, surely use a thermo switch in the load
circuit.
Tighten the terminal screws to between 0.74 and 0.90
N·m.
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 may occasionally result in electric
shock, fire, or malfunction.
• Make sure the proper product is specified for the application.
• For correct use, do not subject the product to the following
conditions.
• Dramatic temperature fluctuations
• High humidity or where condensation may occur
• Severe vibration and shock
• Where excessive dust, corrosive gas, or direct sunlight may be
present
• This product is not waterproof or oil resistance. Do not use the
product in any of the places subject to splashing liquid or oil
atmosphere.
• Use and store the product within the rated ranges given for the
product model you are using. If necessary, use forced cooling. If the
product is stored below −10°C, allow it to warm up for three hours
at room temperature before turning ON the power supply.
• Do not cover the vent holes on the products and the area around
the product in order to ensure thermal dissipation.
• Wiring all terminals correctly.
• Do not wire the terminals which are not used.
• Use specified size crimped terminals (M3.5, thickness 7.2 mm
max.) for wiring with a gage of AWG 24 to AWG 18 (equal to a
cross section area of 0.205 to 0.823 mm2).
(The wiring stripping length is 5 to 6 mm.)
Up to two wires of same size and type, or two crimped terminals
can be inserted into a single terminal.
• Use this product within the rated power supply voltage and control
output.
• Use a switch, relay, or other contact to turn the power supply ON
instantaneously. If the voltage is applied gradually, the power may
not be reset or output malfunctions may occur.
• Do not apply the supply voltage directly from external to transistor
output.
• Interlock the power to the product with a relay so that the product
will not be left in an output on condition for long periods. Leaving
the product in an output-on condition for a month or longer,
especially in places with high temperatures, may result in
deterioration to internal parts, such as an electrolytic capacitor.
• Internal circuit voltage (5 V) is output to the novoltage input terminals, which may cause some
Sensor
connected devices to malfunction or fail. Check the
specifications of the input device (e.g., rated output
voltage or whether a power supply circuit diode is
0V
Input
built in).
To prevent power supply devices from being subjected to charging
accidents, connect a diode as in the figure when using a power
supply voltage of 5 V or less to operate input devices that do not
have a diode built into the power supply circuit.
• Check that the LED indicators are operating normally. Depending
on the operating environment, the indicators and plastic parts may
deteriorate faster than expected, causing the indicators to fail.
Periodically perform inspections and replacements.
• Use tools when separating parts for disposal.
• When disposing of the product, observer all local ordinances as
they apply.
Precautions for Correct Use
• Inrush current will be carried when turning on the power. If the
capacity of the power for the product is insufficient, the product
cannot start. Use a power supply, breakers, contacts which
sufficient capacity.
100 to 240 VAC specifications Approx. 0.8 A for 264 VAC
12 to 48 VDC specifications Approx. 0.4 A for 52.8 VDC
• Since 50 ms after the power is turned ON is required as the raise
time of the internal circuit voltage, note that the product may not
operate in response to any input signal during this period.

H5CN
• Since100 ms after the power is turned OFF (or momentary power
failures) is required as the fall time of the internal circuit voltage,
note that the product may respond to input signals during this
period.

Operation Examples
• During Incremental Operation
If the set value is changed to a value higher than the currently
displayed present value, the timer will time out for the new set
value.
• During Decremental Operation
When the set value changes, the difference between the new set
value and old set value will be added or subtracted from the
present value.

when the power is interrupted.
• All number display digits on the Timer will be OFF when the reset
signal is input. When the reset signal is completed, the numeric
display will show the reset value.
• Model H5CN 12-48 VDC specification use transformer-less power
supply which the power terminals and input terminals are not
insulated. When use this specification, the internal parts of the
product may be occasionally burnt (damaged) if the wiring is not
correct. Pay attention to check the wiring before use.
• The H5CN Timer is capable of reading the input data at any time
during normal operation. This means that the set time can be
changed during power application. This feature sets back the
output from the timer by temporarily setting the longer time or
quickens the output by setting the shorter time. During normal
operation, the set time may be accidentally changed by touching a
thumbwheel switch causing the timer to operate with a different set
time. To prevent this possibility, use the optional Y92A-48B
Protective Cover.
• When the set time is all zeroes (e.g., 000.0 s or 00 h 00 min), there
will be a momentary control output upon power application, which
can be used to check normal output. When changing the set time
during normal operation, pay special attention not to alter the set
value to this all zeroes.
• When changing the set time while power is being supplied, an
inadequate push of the thumbwheel switches will display two
numbers in one digital display window, causing the operating count
to drift widely. Therefore, press the thumb-wheel switches surely.
Take particular care when the other three digits are all zeroes,
because the improper setting of the fourth switch to create four
zeroes will cause an instantaneous output.

Inputs and Outputs
• Do not apply voltage externally to input terminals A, C, and D.
• When using contacts for the reset input and gate input, use goldplated contacts with good contact reliability. Use gate input
contacts with short contact bounce (chattering).
Power Failure Backup Memory
• The product memorizes the status just before occurring the electric
failure memory with non-volatile memory. The rewriting lifespan of
the non-volatile memory is 1,000,000 or more. The non-volatile
memory rewrites the setting condition into the initial setting one
when the power OFF. (-M type only)

Recovery method
As an action, turn the power OFF then back ON again. If the display
restored to normal, then a probable cause can be external noise
affecting the system. Check for external noise. In the case of e3,
input gate (“0000” will be displayed) and turn power ON again. After
that, if it still remains the same, the product must be repaired.

settings
The Timer manufactured in April 2014 or after will be
upgraded. The major changes are described below.
• Backup Battery Connection to Timers with Memory Backup
Previously, an external backup battery was required for
Timers with memory backup, but the Timer has been
upgraded so that the external battery is no longer necessary.
