## ■ **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)** 

## **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. 

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 exactly the same time scale.

## **O eration p** 

## ■ **Basic Operation** 

## **Setting of Selector** 

The selectors can be turned clockwise and counterclockwise to select the desired time scale, or operating mode. 

## **Time Setting** 

Use the ON/OFF-time setting dials to set the ON/OFF time. 

> Each selector has a snap mechanism that secures the selector at a **Locking/Unlocking of Selectors and** 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 **Time Setting Dial** 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. 

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. 

## **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.

- **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.

## **O eration p** 

## ■ **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 multiplication 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. 

||**Star-delta transfer time**|**Star-delta transfer time**|**Star-delta transfer time**|**Star operation time scale**|**Star operation time scale**|**Star operation time scale**|

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

## ■ **Changing of Setting** 

## **Switching Current vs. Ambient Temperature (When Mounting Two or More H3DS - - Units Side by Side)** 

~~!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 terminal 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, 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. 

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.

**----- Start of picture text -----**<br>
If the load current is continuously being supplied to the Timer for a<br>long period of time, be sure to provide the mounting clearance as<br>shown in the figure below. If used under the conditions other than B1 A1<br>those specified below (except for the H3DS-XL@), the life of internal AC/DC<br>components may be shortened due to an excessive rise in the inter-nal temperature. power supply Input circuit Power supply circuit<br>A2<br>TOL ==<br>H3DS H3DS H3DS<br>Go Go Go<br>the on/off state of the power supply.<br>DIN track<br>is applied to the input circuit.<br>t t<br>HEFP] Ed qe due to a sneak current to the transformerless power supply.<br>t: Mounting clearance (mm)<br>**----- End of picture text -----**<br>


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. 

Common to All Timers **H3DS** 

B-48 

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 output. 

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, separate the Timer, wiring, and the equipment which generates the input signals as far as possible from the noise sources. It is also recommended to shield the input signal wiring to prevent electronic interference. 

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 electrolytic 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 circuitry and non current-carrying metal part of the Timer, in order to prevent the internal circuitry of the Timer from damage.
