[. . . ] Solid-state Timer Timers 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. [. . . ] The minimum applicable load is 10 mA at 5 VDC (failure level: P).

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. DC supply voltage does not require the designation of polarity. B-26 Solid-state Twin Timer H3DS-F 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. 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 clockwise until the dial or selector is completely covered with the red cover. To unlock, turn the Lock Key in the opposite direction. 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.

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 reset time requires a minimum of 0. 1 s. 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.

[. . . ] Make sure that the voltage is applied within the specified range, otherwise 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, otherwise the Timer may not start due to inrush current (approx. 3 A) that may flow for an instant when the Timer is turned on. [. . . ]
