Safety Precautions
Be sure to read precautions for all models in the website at the following URL: http://www.ia.omron.com/.
Warning Indications
Meaning of Product Safety Symbols
Risk of fire and explosion due to arcing and relay heat
generation that accompanies switching. Do not use in
an environment where flammable or explosive gas is
present.
The service life of the output relay varies widely
depending on switching capacity and switching
conditions. Use only within the rated load and electrical
life count, based on actual conditions of use. Risk of
contact sticking and burning if used past the service
life. Always use a load current that does not exceed the rating, and if
a heater is used, use a thermal switch in the load circuit.
Do not remove the outer casing.
In rare circumstances there is a risk of slight electrical
shock, fire, or device damage. Do not disassemble,
modify, repair, or otherwise touch the inside.
Tighten the screws for the lead wires to the Socket to
the following torque.
PYF Socket: 0.78 to 1.18 N·m
This is the recommended range when crimp terminals
are used.
If the screws are not tightened sufficiently on Front-connecting
Sockets, the lead wires may come off, connection failure may cause
abnormal heating, or fires may occur.
If they are tightened excessively, the screw threads may be damaged.
Confirm that the setting dial, indicators and plastic parts are operating
normally. Depending on the operating environment, the setting dial,
indicators and plastic parts may deteriorate faster than expected,
causing the indicators to fail. Periodically perform inspections and
replacements.
We recommend that you use a surge absorber if surge voltages may occur.
When you dispose of the Timer, do so according to all local
ordinances for processing industrial waste.
• When selecting a control output, use the H3Y-2/H3YN-2/H3Y-2-B/
H3YN-2-B for switching ON and OFF the power and the H3Y-4/
H3YN-4/H3Y-4-B/H3YN-4-B for switching ON and OFF the minute
load. Gold-plated relays are used in the H3Y-4, H3YN-4, H3Y-4-B,
H3YN-4-B, H3YN-4-Z, H3YN-41-Z, H3YN-4-Z-B, and H3YN-41-Z-
B Series.
• Connect the power supply between terminals A1 (13) and A2 (14).
For a DC power supply, connect the negative side to A1 (13) and
the positive side to A2 (14).
• The operating voltage will increase when using the H3Y/H3YN/
H3Y-B/H3YN-B in any place where the ambient temperature is
more than 50°C. Supply 90% to 110% of the rated voltages (at
12 VDC: 95% to 110%) when operating at 45°C or higher.
• Do not leave the H3Y/H3YN/H3Y-B/H3YN-B in time-up condition
for a long period of time (for example, more than one month in any
place where the ambient temperature is high), otherwise the
internal parts (aluminum electrolytic capacitor) may become
damaged. Therefore, the use of the H3Y/H3YN/H3Y-B/H3YN-B
with a relay as shown in the following circuit diagram is
recommended to extend the service life of the H3Y/H3YN/H3Y-B/
H3YN-B.
• The H3YN/H3YN-B must be disconnected from the Socket when
setting the DIP switch, otherwise the user may touch a terminal
imposed with a high voltage and get an electric shock.
• Do not connect the H3Y/H3YN/H3Y-B/H3YN-B as shown in the
following circuit diagram on the right hand side, otherwise the
H3Y's/H3YN's/H3Y-B's/H3YN-B's internal contacts different from
each other in polarity may become short-circuited.
• Use the following safety circuit when building a self-holding or self-
resetting circuit with the H3Y/H3YN/H3Y-B/H3YN-B and an
auxiliary relay, such as an MY Relay, in combination.
CAUTION Indicates a potentially hazardous situation
which, if not avoided, may result in minor
or moderate injury or in property damage.

• In the case of the above circuit, the H3YN will be in pulse operation.
Therefore, if the circuit shown on page 13 is used, no auxiliary
relay will be required.
• Do not set to the minimum setting in the flicker modes, otherwise
the contact may become damaged.
• Be careful not to apply any voltage to the terminal screws on the
back of the Timer. Mount the product so that the screws will not
come in contact with the panel or metal parts.
• Do not use the H3Y/H3YN/H3Y-B/H3YN-B in places where there
is excessive dust, corrosive gas, or direct sunlight.
• Do not mount more than one H3Y/H3YN/H3Y-B/H3YN-B closely
together, otherwise the internal parts may become damaged.
Make sure that there is a space of 5 mm or more between any H3Y/
H3YN/H3Y-B/H3YN-B Models next to each other to allow heat
radiation.
• The internal parts may become damaged if a supply voltage other
than the rated ones is imposed on the H3Y/H3YN/H3Y-B/H3YN-B.
When more than 100 V is applied to 12 or 24 VDC models, the
internal element (varistor) may break.
• In order to conform to UL and CSA requirements when using the
H3Y-4/-4-0/-4-B, H3YN-4/-41/-4-B/-41-B, or H3YN-4-Z/-41-Z/
-4-Z-B/-41-ZB, connect the Unit so that output contacts (contacts
of different poles) have the same electric potential.
• In cases such as PLC input where the load is extremely small for
the control output of a timer containing a power relay (using other
than gold-plated contacts), reliability can be increased by using
contacts of the same poles (e.g., the H3Y-2) in parallel.
• Always use the same type of wire.
• Installation
There are no restrictions on the installation orientation. Install the
Timer securely.
Precautions for EN 61812-1 Conformance
The H3Y/H3YN/H3Y-B/H3YN-B as a built-in timer conforms to EN
61812-1 provided that the following conditions are satisfied.
Handling
• Do not touch the DIP switch while power is supplied to the H3YN/
H3YN-B.
• Before dismounting the H3YN/H3YN-B from the Socket, make
sure that no voltage is imposed on any terminal of the H3YN/
H3YN-B.
• The applicable Socket is the PYF@A (H3Y/H3YN) or PYF-@-PU-L
(H3Y-B/H3YN-B).
• Only basic insulation is ensured between the Y92H-3 Hold-down
Clips and H3Y/H3YN/H3Y-B/H3YN-B internal circuits.
• Do not allow the Y92H-3 Hold-down Clips to contact other parts.
• The insulation test voltage between different pole contacts for the
4-pole model is the impulse voltage of 2.95 kV.
Wiring
• The power supply for the H3Y/H3YN/H3Y-B/H3YN-B must be
protected with equipment such as a breaker approved by VDE.
• Basic insulation is ensured between the H3Y's/H3YN's/H3Y-B's/
H3YN-B's operating circuit and control output.
• Insulation requirement:
Overvoltage category II,
pollution degree 1 (H3Y-4/-4-0/-4-B, H3YN-4/41/-4-B/-41-B,
H3YN-4-Z/-41-Z/-4-Z-B/-41-Z-B),
pollution degree 2 (H3Y-2/-2-0/-2-B, H3YN-2/21/-2-B/-21-B)
(with a clearance of 1.5 mm and a creepage distance of 2.5 mm
at 240 VAC)
• Output terminals next to each other on the H3Y-4 or H3Y-4-0 must
have the same polarity.
Recommended Replacement Periods and Periodic Replacement
as Preventive Maintenance
The recommended replacement period for preventive maintenance is
greatly influenced by the application environment of the product. As a
guideline for models that do not have a Maintenance Forecast
Monitor, the recommended replacement period is 7 to 10 years.* To
prevent failures that can be caused by using a product beyond its
service live, we recommend that you replace the product as early as
possible within the recommended replacement period. However,
realize that the recommended replacement period is for reference
only and does not guarantee the life of the product.
Many electronic components are used in the product and the product
depends on the correct operation of these components to achieve
product functions and performance. However, the influence of the
ambient temperature on aluminum electrolytic capacitors is large, and
the service life is reduced by half for each 10°C rise in temperature
(Arrhenius law). When the capacity reduction life of the electrolytic
capacitor is reached, the product may fail. We therefore recommend
that you replace the product periodically to minimize product failures
in advance.
*The following conditions apply: rated input voltage, load rate of 50%
max., ambient temperature of 35°C max., and the standalone
mounting method.
This product model is designed with a service life of 10 years
minimum under the above conditions.
