Operation
■Basic Operation
Setting of Selector
The selectors can be turned clockwise and counterclockwise to
select the desired time unit, time scale, or operating mode.
Each selector has a snap mechanism that secures the selector at a
given position. Set the selector at a position at which it is secured. Do
not set it midway between two securing positions or a malfunction
could result from improper setting.
Selection of Operating Mode
The H3DE-M/-S can be set to any one of the operating modes A to J.
Turn the operating mode selector with a screwdriver until the desired
operating mode (A, B, C, B2, D, E, J, or G for the H3DE-M and A, E,
J, or B2 for the H3DE-S) appears in the operating mode display win-
dow located below the selector.
Selection of Time Unit and Time Scale
The desired time unit (s, m, h, or 10h) can be displayed in the time
unit display window above the time setting dial by turning the time
unit selector located at the upper right corner of the front panel. Time
scale (0.1 or 1) is selected with the time scale selector at the upper
left corner of the front panel, it appears in the time scale display win-
dow above the selector.

■Timing Chart
Note: 1. The minimum power reset time is 0.1 s and the minimum signal input time is 0.05 s.
2. The letter “t” in the timing charts stands for the set time and “t–a” means that the period is less than the time set.
3. There is no start input with H3DE-S@ models. Operation starts when the power is turned ON.
4. There is no instantaneous output with H3DE-M1/-S1 models.
Note: The start input of the H3DE-M1 or H3DE-M2 model is activated by applying a voltage to B1 and A2 terminals.
The voltage can be applied by turning on the contact between B1 and A1 (Refer to Terminal Arrangement on page 6)

Operation
■Basic Operation
Time Unit Selection
The time unit display window for output ON is located on the upper-
right side of the front panel above the corresponding time unit selec-
tor.
The time unit display window for output OFF is located on the lower-
right side of the front panel below the corresponding time unit selec-
tor.
According to the setting of each time unit selector, “sec” for seconds,
“10s” for 10 seconds, “min” for minutes, or “hrs” for hours will appear
in the corresponding time unit display window.
Time Scale Selection
The time scale selector on the upper-left side of the front panel can
be set to 0.1 or 1 as a magnification coefficient.
Time Setting
Use the ON/OFF-time setting dial to set the ON/OFF time.
■Timing Charts
Note: 1. The reset time requires a minimum of 0.1 s.
2. When power is supplied in flicker-ON start mode, the OFF indicator lights momentarily. This, however, has no effect on the performance
of the Timer.

Safety Precautions (Common)
Refer to Safety Precautions for All Timers.
Note: The following is common for all H3DE models.
■Changing of Setting
!CAUTION
Do not change the time unit, time scale, operating mode, or output
type selector switch while the Timer is in operation or malfunction
could result.
■Mounting and Dismounting
The H3DE should be mounted as horizontally as possible.
When mounting the H3DE on a socket mounting track, hook portion
(A) of the Timer to an edge of the track first, and then depress the
Timer in the direction of (B).
When dismounting the H3DE, pull out portion (C) with a flat-blade
screwdriver and remove the Timer from the mounting track.
The H3DE can be mounted and dismounted with ease if a distance
of 30 mm or more is kept between the H3DE and the top surface of
other equipment located below the H3DE.
■Power Supplies
The H3DE Series is provided with a transformerless power supply
system. An electric shock may be received if the input terminal or the
output type selector switch is touched while power is being supplied.
Use the bar terminal for wiring the H3DE. Using a stranded-wire ter-
minal may cause a short-circuit due to a stray wire entering into the
Timer.
Both AC and DC power supplies can be connected to the power
input terminals without regarding polarity.
With the H3DE only, a DC power supply must be connected to the
power input terminals as designated according to the polarity of the
terminals.
A DC power supply can be connected if its ripple factor is 20% or
less and the mean voltage is within the rated operating voltage range
of the Timer.
Connect the power supply voltage through a relay or switch in such a
way that the voltage reaches a fixed value at once or the Timer may
not be reset or a timer error could result.
For the power supply of an input device, use an isolating transformer,
of which the primary and secondary windings are mutually isolated
and the secondary winding is not grounded.
The H3DE-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.
■Installation
If the load current is continuously being supplied to the Timer for a
long period of time, be sure to provide the mounting clearance as
shown in the figure below. If used under the conditions other than
those specified below, the life of internal components may be short-
ened due to an excessive rise in the internal temperature.

■Input/Output
Relationship between Input and Power
Supply Circuits
Since the input circuit and the power supply circuit are configured
independently, the input circuit can be turned on or off irrespective of
the on/off state of the power supply.
It must be noted that a voltage equivalent to the power supply voltage
is applied to the input circuit.
When connecting a relay or a transistor as an external signal input
device, pay attention to the following points to prevent short-circuiting
due to a sneak current to the transformerless power supply.
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 different in phase or the terminals will be short-circuited to one
another (refer to the figures below).
The H3DE Series is provided with a transformerless power supply
system.
■Input Wires
The input wires must be as short as possible. If the floating capacity
of wires exceeds 2,000 pF (approx. 17 m for cables with 120 pF/m),
the operation will be affected. Pay particular attention when using
shielded cables.
■Wiring (H3DE-H)
The H3DE has a high impedance circuit. Therefore, the H3DE may
not be reset if the H3DE is influenced by inductive voltage. In order to
eliminate any influence of inductive voltage, the wires connected to
the H3DE must be as short as possible and should not be installed
alongside power lines. If the H3DE is influenced by inductive voltage
that is 30% or more of the rated voltage, connect a CR filter with a
capacitance of approximately 0.1 µF and a resistance of approxi-
mately 120 Ω or a bleeder resistor between the power supply termi-
nals. If there is any residual voltage due to current leakage, connect
a bleeder resistor between the power supply terminals.

■Operation (H3DE-H)
An interval of 3 s minimum is required to turn on the H3DE after the
H3DE is turned off. If the H3DE is turned on and off repeatedly with
an interval of shorter than 3 s, the internal parts of the H3DE may
deteriorate and the H3DE may malfunction.
If it is required that the output be turned on repeatedly with an inter-
val of shorter than 3 s, consider use of the H3DE-M2/-M1 in mode D
(signal OFF-delay).
■Precautions for EN61812-1
Conformance
The H3DE as a built-in timer conforms to EN61812-1 provided that
the following conditions are satisfied:
The output section of the H3DE is provided only with basic isolation.
To ensure reinforced isolation required by the EN61812-1, provide
supplementary basic isolation on the load side connected to the out-
put.
The H3DE itself is designed according to the following:
•Overvoltage category III
•Pollution degree 2
On the above basis:
Operation parts on the front and bottom: Reinforced isolation
- With clearance of 5.5 mm and creepage distance of 5.5 mm at
230 VAC
Output: Basic isolation
- With clearance of 3 mm and creepage distance of 3 mm at
230 VAC
■Environment
When using the Timer in an area with excess electronic noise, sepa-
rate the Timer, wiring, and the equipment which generates the input
signals as far as possible from the noise sources. It is also recom-
mended to shield the input signal wiring to prevent electronic interfer-
ence.
Organic solvents (such as paint thinner), as well as very acidic or
basic solutions can damage the outer casing of the Timer.
Do not use the Timer in places where it is exposed to dust, corrosive
gas, or direct sunlight.
When storing the Timer, make sure that the ambient temperature
and humidity are within the rated values. Leave the Timer at room
temperature for at least three hours before using the Timer if it has
been stored at an ambient temperature of –10°C or below.
■Others
If the Timer is mounted on a control board, dismount the Timer from
the control board or short-circuit the circuitry of the power board
before carrying out a voltage withstand test between the electric cir-
cuitry and non current-carrying metal part of the Timer, in order to
prevent the internal circuitry of the Timer from damage.
It must be noted that although the electrical life expectancy of the
H3DE Timer shown in the catalog is the same as the H3DR Timer
shown in the catalog, the actual performance varies because the
built-in relays are different as follows:
Built-in relay for the H3DR: G2R; 100,000 operations min.
(10 A for SPDT and 5 A for DPDT at
250 VAC, resistive load at
1,800 operations/h.)
Built-in relay for the H3DE: G6RN; 50,000 operations min.
(8 A at 250 VAC, resistive load at
360 operations/h.)
