Solid-state Timer
H3DS
DIN Track Mounted, Standard 17.5-mm Width Timer Range
• A wide AC/DC power supply range (24 to 230 VAC/ 24 to 48 VDC) reduces the number of timer models kept in stock.
(24 to 230 VAC/VDC with H3DS-XL@)
• Smart Dial/Selector-locking Mechanism: Prevents the dials and selectors on the Timer’s front panel from being inadvertently
operated or being operated without authorization. The lock can only be unlocked and locked with an optional pen-type Lock Key.
• Screw-Less Clamp type available. (H3DS-@LC)
• Sticker provided for easy timer identification and management.
• Terminal clamp left open when delivered (screw terminal type).
• Finger protection terminal block to meet VDE0106/P100.
• Enables easy sequence checks through instantaneous outputs for a zero set value at any time range.
• Incorporates environment-friendly, cadmium-free contacts.
• Conforms to EN61812-1 and IEC60664-1 4 kV/2 for Low Voltage, and EMC Directives.

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 window.
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 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 selector is completely covered with
the red cover. To unlock, turn the Lock Key in the opposite direction.

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.
