Operation
■Basic Operation
Setting of Selector
The selectors can be turned clockwise and counterclockwise to
select the desired 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 (except
for H3DS-AL)
The H3DS-ML/-SL 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 appears in the operating mode display win-
dow.
H3DS-ML (8 modes): A, B, B2, C, D, E, G, J
(In order of appearance)
H3DS-SL (4 modes): A, E, B2, J, E, E, J, J
(In order of appearance)
Note: Letters that appear more than once indicate exactly the same
operating mode.
Selection of Time Scale
The time scale is selected by turning the time scale selector. The
time scales will appear in the following order in the time scale display
window on the left of the selector:
1 s, 0.1 s, 1 h, 0.1 h, 10 h, 1 h, 1 m, 0.1 m.
Note: The time scale “1h” appears twice. Both instances indicate ex-
actly the same time scale.
Locking/Unlocking of Selectors and
Time Setting Dial
The time setting dial, time scale selector, and operating mode selec-
tor can be locked using the Y92S-38 Lock Key, a special pen type
tool that is sold separately. To lock the dial or selectors, insert the
Lock Key in the keyhole to the lower right of the dial or selector and
turn it clockwise until the dial or selector is completely covered with
the red cover. To unlock, turn the Lock Key in the opposite direction.

■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 for H3DS-SL@/-AL@ models. Operation starts at power-on.
Note: The start input of the H3DS-ML@ 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).

Operation
■Basic Operation
Setting of Selector
The selectors can be turned clockwise and counterclockwise to
select the desired 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.
Settings for ON/OFF Start
If voltage is applied to terminal B1, or if terminals A1 and B1 are
shorted, the operating mode is switched to flicker-ON start mode. If
these terminals are disconnected, the mode switches to flicker-OFF
start mode. The operating mode will not change if the state of the
applied voltage changes during timer operation.
Selection of Time Scale
The time scale is selected by turning the ON-time scale selector and
OFF-time scale selector. The time scales will appear in the following
order in each time scale display window on the left of the selector:
0.1 s, 1 h, 0.1 h, 1 m, 1 s, 0.1 h, 0.1 m, 1 s.
Note: The time scales “1 s” and “0.1 h” appear twice. Both instances
indicate exactly the same time scale.
Time Setting
Use the ON/OFF-time setting dials to set the ON/OFF time.
Locking/Unlocking of Selectors and
Time Setting Dial
The ON/OFF-time setting dials and time scale selectors can be
locked using the Y92S-38 Lock Key, a special pen type tool that is
sold separately. To lock the dials or selectors, insert the Lock Key in
the keyhole to the lower right of the dial or selector and turn it clock-
wise until the dial or selector is completely covered with the red
cover. To unlock, turn the Lock Key in the opposite direction.
■Timing Charts
Note: 1. If voltage is applied to terminal B1, or if terminals A1 and B1 are shorted, the operating mode is switched to flicker-ON start mode. If these
terminals are disconnected, the mode switches to flicker-OFF start mode.
2. The reset time requires a minimum of 0.1 s.
3. 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.

■Basic Operation
Setting of Selector
The selectors can be turned clockwise and counterclockwise to
select the desired 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 Time Unit and Time Scale
The star-delta transfer time and star operation time scale are set with
the same selector. The star-delta transfer time can be set to 0.05,
0.1, 0.5, or 1. The star operation time scale can be set to a multiplica-
tion factor of 1 or 10. If the star-delta transfer time is displayed in the
display window in white letters, this means that the star operation
time scale is “x10”. Refer to the example below.
Time Setting
The star operation time of the Timer is set with the time setting dial.
Locking/Unlocking of Selectors and
Time Setting Dial
The time setting dial and time scale selector can be locked using the
Y92S-38 Lock Key, a special pen type tool that is sold separately. To
lock the dial or selectors, insert the Lock Key in the keyhole to the
lower right of the dial or selector and turn it clockwise until the dial or

Safety Precautions
■Changing of Setting
!CAUTION
Do not change the time scale or operating mode, while the Timer is in
operation or malfunction could result.
■Power Supplies
The H3DS Series is provided with a transformerless power supply
system. An electric shock may be received if the input terminal is
touched while power is being supplied.
Use the bar terminal for wiring the H3DS. 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 H3DS 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.
Make sure that the voltage is applied within the specified range, oth-
erwise the internal elements of the Timer may be damaged.
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.
Be sure that the capacity of the power supply is large enough, other-
wise the Timer may not start due to inrush current (approx. 3 A) that
may flow for an instant when the Timer is turned on.
For the power supply of an input device of the H3DS-ML@, use an
isolating transformer, of which the primary and secondary windings
are mutually isolated and the secondary winding is not grounded.
■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 (except for the H3DS-XL@), the life of internal
components may be shortened due to an excessive rise in the inter-
nal temperature.

■Input/Output
Relationship between Input and Power
Supply Circuits (H3DS-ML@)
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 H3DS 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.
■Precautions for EN61812-1
Conformance
The H3DS as a built-in timer conforms to EN61812-1 provided that
the following conditions are satisfied:
The output section of the H3DS 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 H3DS 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.
Leaving the Timer with outputs ON at a high temperature for a long
time may hasten the degradation of internal parts (such as electro-
lytic capacitors). Therefore, use the product in combination with
relays and avoid leaving the product as long as more than 1 month
with the output turned ON.
■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.
