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. 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. 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.

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. Switching Current vs. Ambient Temperature (When Mounting Two or More H3DS Units Side-by-Side) * H3DS-ML@/-SL@/-AL-@ 70 Ambient temperature (C) !CAUTION 50 30 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.

Mounting clearance: 0 mm 40 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. Mounting clearance: 5 mm Maximum range of operating ambient temperature 60 Load current (A) Input/Output Isolation transformer is required. 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 internal temperature. Relationship between Input and Power Supply Circuits (H3DS-ML@) B1 AC/DC power supply Input circuit A1 Power supply circuit A2 H3DS H3DS H3DS DIN track t t 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. t: Mounting clearance (mm) 37 H3DS 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 as a built-in timer conforms to EN61812-1 provided that the following conditions are satisfied: Contact or transistor for external input signal A1 B1 Incorrect Precautions for EN61812-1 Conformance H3DS-ML@ Power supply 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: A2 * Overvoltage category III * Pollution degree 2 A1 On the above basis: Short-circuit current Operation parts on the front and bottom: Reinforced isolation B1 H3DS-ML@ - With clearance of 5.5 mm and creepage distance of 5.5 mm at 230 VAC Output: Basic isolation A2 - With clearance of 3 mm and creepage distance of 3 mm at 230 VAC Contact or transistor for external input signal Environment A1 B1 H3DS-ML@ Correct Power supply A2 Short-circuit current A1 B1 H3DS-ML@ A2 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. 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 -10C 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.
