Safety Precautions

●Refer to Safety Precautions for All Timers.

Note: The following is common for all H3DK models.

Switching arcs or relay heating may cause fire or

explosion. Do no t use the Timer in the presence of

inflammable or explosive gases.

The H3DK Series uses a transformerless power

supply system. An electrical shock may occur if

an input terminal is touched while power is being

supplied.

The inrush current will depend on the type of load

and may influence the contact switching fre-

quency and number of o peration s. Chec k b oth the

rated current and the inrush current, and allow

leeway in the circuit design.

The life of the output relay largely depends on the

switching current and other switch conditions.

Consider the actual application conditions and do

not exceed the rated load or electrical life. If the

output relay is used beyond its service life, the contacts

may fuse or burning may occur. Also, never exceed the

rated load current. When using a heater, also place a ther-

mal switch in the loa d ci rc ui t.

Do not remove the external case.

Minor electric shock, fire, or equipment failure

may sometimes occur. Do not disassemble, mod-

ify, or repair the Timer or touch any in ternal parts.

• Use ferrules to wire t he H3DK. If stranded wires are use d, wire

scraps may enter the Timer, possibly shorting the circuits.

• Rapid changes in temperature or high humidity may cause

condensation in Timer circuits, possibly resulting in malfunc-

tion or damage to components. Check the application environ-

ment.

• Store the Timer within the rated ranges given for the Timer

model you are using. If the Timer is stored below −20°C, allo w

it to warm up for three hours at room temperature before turn-

ing ON the power supply.

• Use the Timer within the ambient operating temperature and

ambient operating humidity ranges given for the Timer model

you are using.

• Use the Time within the characteristics for water and oil expo-

sure given fo r t he Tim e r m o de l yo u ar e us ing.

• Do not use the Timer in locations subject to excessive dust,

corrosive gas, or direct sunlight.

• Do not use the Timer in locations subject to vibration and

shock. Long-term exposure may damage the Timer due to

stress.

• Separate the Timer from any sources of excessive static elec-

tricity, such as forming materials and pipes carrying power or

liquid materials.

• Maintain the variations in the power supply voltage to within

the specified allowable range.

• If a voltage that exceeds the rating is applied, internal compo-

nents may be destroyed.

• Wire all terminals correctly.

• Use only the specified wires for wi ring.

Applicable wire gauge: AWG18 to AWG22

• Install and clearly label a switch or circuit breaker so that the

operator can quickly turn OFF the power supply.

• If th e T imer is lef t in the t i med o ut cond it io n for a lon g pe ri od of

time at high temperatures, internal components (such as elec-

trolytic capacitors) may deteriorate quickly.

• The ext erior of t he Timer may b e damaged by organic so lvents

(such as thinners or benzene), strong alkali, or strong acids.

• For Timers wi th AC power input , use a commerci al power sup -

ply for the power supply voltage. Although some inverters give

50/60 Hz as the output frequency, do not use an inverter out-

put as the power supply for a Timer. Doing so may result in

smoking or burning due to internal temperature increases in

the Timer.

• Use the same type of wiring for all Timer wiring.

• When disposing of the Timer, observe all local ordinances as

they apply.

• The Timer may not operate properly in locations that are sub-

ject to sulfide gas, such as in sewers or incinerators. Products

that are suitable for operation in sulfide gas are not available

for OMRON Timers or general control devices. Seal the Timer

to isolate it from sulfide gas. If the Timer cannot be sealed,

OMRON can make special products with resistance to sulfide

gas for some Timers. Ask your OMRON representative for

details.

• Confirm that the power and output indicators are operating

normally. Depend ing on th e operati ng environme nt, th e indica-

tors and plastic parts may deteriorate faster than expected,

causing the indicators to fail. Periodically perform inspections

and replacements.

Caution Precautions for Safe Use

H3DK

●Changing Switch Settings

Do not change the time uni t, time sca le, opera ting mode, or INI T/

TIME switch while the Timer is in operation. Doing so may result

in malfunction. Turn OFF the power supply before changing the

setting of any switch.

●Mounting and Dismoun tin g

• Although there are no particular mounting restrictions, the

Timer should be mounted as horizontally as possibl e.

• When mounting the Timer on a mounting Track, loosen the

two hooks, press the Timer onto the Track, and then insert the

hooks.

• When removing the Timer, pull out the two hooks, and then

remove the Timer from the Track

• It will be easier to mount and dismount the Timer if a distance

of 30 mm or more is provided between the bott om of the Timer

and other equipment.

●Power Supply

• The power supply can be connected to the power input termi-

nals without considering polarity.

• A DC power supply can be connected if its ri pple factor is 20%

or less and the average voltage is within the allowable voltage

fluctuation range of the Timer.

• For the power supply of the input device, use an isolating

transformer in which the primary and secondary windings are

mutually isolat ed and the secondary winding is not grounded.

(H3DK-M1 and H3DK-M2 only)

• The H3DK-H has a large inrush current. Provide sufficient

power supply capacity.

If the power supply capacity is too small, there may be delays

in turning ON the output.

●Relationship between Input and Power Supply Cir-

cuits (H3DK-M1/-M2)

• The input circuit and the power supply circuit are configured

independently. The input circuit can be turned ON and OFF

without considering the ON/OFF state of the power supply.

A voltage equivalent to the power supply voltage is also

applied to the input circuit.

• If a relay or transistor is connected to two or more Timers, the

input terminals of those Timers must be wired properly so that

they will not be dif f erent in p hase o r the t ermin als wi ll be short-

circuited to one another. Always use the same power supply

phases.

●Environment

• When using the Timer in an area with excessive electronic

noise, separate the Timer and input device as far as possible

from the noise sources. It is also recommended to shield the

input signal wiring to prevent electronic interference.

• The extern al impuls e voltage entering across the power s upply

terminals has been checked against a ±1.2×50 µs standard

waveform according to JEC-210, Impulse Voltage/Current

Test, of The Institute of Electrical Engineers of Japan. Surge

or noise superimposed on the power supply may damage

internal components or cause t hem to malfu nction . We recom-

mend that you check the circuit waveform and use surge

absorbers. The effects on components depend on the type of

surge and noise that are generated. Always perform testing

with the actual equipment.

●Wiring

The H3DK-H acts like a high-impedance circuit. Therefore, the

Timer may not reset if it is influenced by inductive voltage. To

eliminate inductive voltage, the wires connected to the Timer

must be as short as possible and should not be installed parallel

to power lines. If the Ti mer is inf luence d by i ndu ctiv e volt age tha t

is 30% or more of the rated voltage, connect a CR filter with a

capacitance of approximately 0.1 µF and a resistance of approx-

imately 120 Ω or a bleeder resistor between the power supply

terminals.

If there is any residual voltage due to current leakage, connect a

bleeder resistor between the power supply terminals.

●Operating Frequency

• The H3DK-H may malfunction if it is used as shown below. Do

not use the H3DK-H in these ways.

Timer Repeatedly Ti mes Out in Cycles of 3 s or Less

In the above case, use the H3DK-M2/-M1 in D mode (signal

OFF delay).

●DC Power Consumptions (Reference Information)

●Other Precautions

• If the Timer is mounted on a control panel, dismount the Timer

from the control panel before carrying out a voltage withstand

test between the electric circuits and non-current-carrying

metal parts o f the T imer. (Ot herwise , the i nt ernal ci rcui ts o f the

Timer may be damaged.)

• The H3DK-H uses a latching relay for the output. Shock, such

as dropping the H3DK-H during shipment or handling, can

cause the output contacts to reverse to the neutral position.

Check the output status with a tester before using the H3DK-

• The life expectancy of the control output contacts is greatly

affected by switching conditions. Always confirm operation

using the actual conditions and equipment before using the

Timer and make sure that the number of switching operations

presents no problems in performance. If Timer application is

continued after performance has deteriorated, insulation fail-

ure between circuits, burning of the control output relay, or
