Solid-state Timer H3BA-N 7 ■Basic Setting Setting of Selector The selectors can be turned clockwise and counterclockwise to select the desired time unit, time range, output type (only for H3BA- N8H) 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 with H3BA-N Turn the operating mode selector with a screwdriver until the desired operating mode (A, B, B2, C, D, E, G, or J) appears in the display window located above the selector. Selection of Output Type with H3BA-N8H Turn the output type selector with a screwdriver until the desired out- put type (A or H) appears in the display window located above the selector. Selection of Time Unit and Time Range The desired time unit (sec, 10 s, min, 10 m, hrs, or 10 h) is displayed in the window below the time setting knob by turning the time unit selector located at the lower right corner of the front panel. A time range (1.2, 3, 12, or 30) is selected with the time range selector at the lower left corner of the front panel, and the selected time range appears (in the window at the lower right part) within the plastic frame of the time setting knob. Setting of Time Use the time setting knob to set the desired time. ■Using the Setting Ring Setting a Specific Time Mount the Panel Cover on the Timer, set the desired time with the time setting knob, and place Time Setting Ring A onto the time setting knob so that the time setting notch of Time Setting Ring A is in the center of the reset lock position of the Panel Cover. Limiting the Setting Range Example: To set a range of 10 and 20 s. Mount the Panel Cover on the Timer, set the time setting knob to 10 s (the lower limit of the setting range), and place Time Setting Ring C onto the time setting knob so that the stopper of Time Setting Ring C is on the right edge of the reset lock position of the Panel cover. Next, set the time setting knob to 20 s (the upper limit of the setting range), place Time Setting Ring B onto the time setting knob so that the stopper of Time Setting Ring B is on the left edge of the reset lock position of the Panel Cover.

The protective cover protects the front panel, particularly the time setting section, against dust, dirt, and water. It also prevents the set value from being altered due to accidental contact with the time setting knob. Note: 1. The Y92A-48B Protective Cover is made of a hard plastic and therefore it must be removed to change the timer set value. 2. The Protective Cover cannot be mounted if the Panel Cov- er (sold separately) is used on the Timer. Y92A-48B Time Setting Ring/Panel Cover There are two types of Panel Covers (Y92P-48GL, Y92P-48GB), all of which are available in two colors. Use the most suitable type of Panel Cover with the design of the scaling plate according to the application. When setting a given time for the Timer, use of the Y92S-27 or Y92S-28 Time Setting Ring facilitates the time setting operation and minimizes possible setting errors by operators.

Solid-state Timer H3BA-N 17 Safety Precautions Warning Indications Meaning of Product Safety Symbols ■Precautions for Safe Use Please observe the following precautions for safe use of this product. Environmental Precautions Store the Timer within specified ratings. If the Timer has been stored at -10°C or lower, let it stand for 3 hours or longer at room temperature before turning ON the power supply. Use the Timer within the specified ratings for operating temperature and humidity. Do not operate the Timer in locations subject to sudden or extreme changes in temperature, or locations where high humidity may result in condensation. Do not use the Timer in locations subject to excessive dust, corrosive gas, or direct sunlight. Do not use the Timer in locations subject to vibration or shock. Extended use in such locations may result in damage due to stress. Install the Timer well away from any sources of static electricity, such as pipes transporting molding materials, powders, or liquids. Usage Precautions Install a switch or circuit breaker that allows the operator to immediately turn OFF the power, and label it to clearly indicate its function. Pay careful attention to polarity to prevent wrong connections when wiring terminals. Internal elements may be destroyed if a voltage outside the rated voltage is applied. Maintain voltage fluctuations in the power supply within the specified range. The Timer uses a transformerless power supply. Do not touch the input terminals while the supply voltage is being applied, otherwise an electric shock may occur. CAUTION Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury or in property damage. Precautions for Safe Use Supplementary comments on what to do or avoid doing, to use the product safely. Precautions for Correct Use Supplementary comments on what to do or avoid doing, to prevent failure to operate, malfunction or undesirable effect on product performance. Used to warn of the risk of electric shock under specific conditions. Used to warn of the risk of minor injury caused by high temperatures Used for general mandatory action precautions for which there is no specified symbol. Use to indicate prohibition when there is a risk of minor injury from electrical shock or other source if the product is disassembled. Minor electric shock may occasionally occur. Do not disassemble the product or touch the interior of the Timer. Minor burns may occasionally occur. Do not touch the product while power is being supplied or immediately after power is turned OFF . Minor fires may occasionally occur. Tighten terminal screws to a torque of 1.08 N·m so that they do not become loose. Minor electric shock may occasionally occur during operation. Install the terminal cover. Minor electric shock, fire, or malfunction may occasionally occur. Do not allow metal fragments, lead wire scraps, or chips from processing during installation to fall inside the Timer. CAUTION

■Precautions for Correct Use Changing the Setting Do not change the time unit, time range, or operation mode while the Timer is in operation, otherwise the Timer may malfunction. Connecting the Operating Power Supply The H3BA-N@ contains a capacitor-drop power circuit. Use a sinusoidal power supply with a commercial frequency. Do not use power supplies with a high frequency component (such as inverter power supplies) for Timers with 110 or 220-VAC specifications. Using these power supplies can damage internal circuits. If voltages other than the rated voltage is applied, the internal components may be damaged. The internal element (varistor) will be damaged if a voltage of higher than 100 VAC is applied to the 24- VDC line. Connect the power supply voltage through a relay or switch in such a way that the voltage reaches a fixed value immediately or the Timer may not be reset or a timer error could result. 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. If the wiring to the terminal 2 (common terminal for both the power supply and input signals) is broken, the internal circuit will be destroyed. Input/Output An appropriate input will be applied to the input signal terminals of the Timer when one of the input terminals (terminals 5, 6, and 7) and the common terminal (terminal 2) for the input signals are short- circuited. Do not attempt to connect any input terminal to any terminal other than the common terminal or to apply voltage across other than the specified input and common terminals or the internal circuits of the Timer may be damaged. Note: 1. Power supply terminal 2 is a common terminal for the input signals (G, S, R) to the Timer. Never use terminal 10 as the common terminal for this purpose, otherwise the internal circuit of the Timer may be damaged. 2. Do not connect a relay or any other load between these two points, otherwise the internal circuit of the Timer may be damaged due to the high-tension voltage applied to the input terminals. Operating Time Setting When setting the operating time, do not turn the setting knob beyond its scale range. For precise time setting, conduct operation tests by adjusting the setting knob. The accuracy of the operating time of the Analog Timer is indicated by the percentage value on the basis of the full-scale time. The absolute fluctuation value will not be improved by changing the time setting. Therefore, when selecting the model, be sure that the application will be able to use a time setting as close as the full-scale time setting of the Timer. Others When conducting a dielectric test, impulse voltage test, or insulation resistance test between the electric circuit and non-current-carrying metal parts of the Timer mounted to a control panel, be sure to take the following steps. These steps will prevent the internal circuitry of the Timer from damage that may be caused if a machine on the control panel has an improper dielectric strength or insulation resistance. 1. Separate the Timer from the circuitry of the control panel by disconnecting the socket from the Timer or wires. 2. Short-circuit all terminals of the Timer. If any device with no-contact output, such as a proximity sensor, photoelectric sensor, or SSR, is directly connected to the Timer, current leakage from the device may cause Timer malfunction. Be sure to test the device with the Timer before using the device for actual applications. Before using the Timer to switch inductive loads, be sure to connect a surge absorbing element to the Timer in order to prevent the Timer from malfunction and damage. A diode is an example of a surge absorbing element for DC circuits and a surge absorber is an example of a surge absorbing element for AC circuits. Do not leave the Timer in time-up condition for a month or longer in places with high temperatures, otherwise the internal parts, such as an electrolytic capacitor, of the Timer may be damaged. Use the Timer with an appropriate relay so that the Timer will not be left in time-up condition for a long time. If the Timer is mounted in contact with a mounting surface, the service life of internal parts may be shortened. Provide at least 10 mm between the Timer and the mounting surface to prolong the service life of the Timer. When the Timer is reset right after the Timer goes into time-up condition, be sure to provide the Timer with an appropriate circuit configuration considering the resetting time of the Timer so that a sequential error will not result. The Timer uses the constant value read method. Be careful when changing the set value because the output of the Timer will be ON when the set value coincides with the count value. Be sure that the casing of the Timer is free from organic solvents, such as paint thinner and benzene, strong acid, and alkali solvents, which will damage the casing. Note: It is impossible to connect more than two Timers in parallel. 5, 6, 7 G, S, R Input terminal H3BA-N Closed Power supply AC or DC Input contact 5, 6, 7 G, S, R Input terminal H3BA-N (See note 2) 2 (see note 1)

Solid-state Timer H3BA-N 19 ■Mounting Surface Mounting There is no particular restriction on surface mounting directions, but be sure that the Timer is securely mounted horizontally. P2CF Socket When mounting the Timer vertically with the P2CF Socket, consider the movable hooks and be sure that there is a 20-mm space on each of the upper and lower parts of the Socket.PL Socket 1. Secure the Socket to the panel surface with screws and insert the F-shaped hook into the sockets. 2. Connect the Timer to the Socket and press the tip of each hook by hand. Panel Mounting When the Y92F-30 Flush Mounting Adapter is used, insert the Timer into the square hole from the front side of the panel and put on the Flush Mounting Adapter from the rear side of the Timer. Press the Flush Mounting Adapter so that the space between the Flush Mounting Adapter and the panel is reduced as much as possible, and secure the Flush Mounting Adapter with screws. When using the US08, be sure to use 10.5-dia. max. multi-conductor cable or 3-dia. max. insulated stranded wire for wiring. When the Y92F-30, Y92F-70 or Y92F-71 Flush Mounting Adapter is used, just insert the Timer into the square panel hole. If the panel coating is too thick and the hooks do not click, spread open the hooks appropriately to the left and right after inserting the Timer to the hole. ■Dismounting Surface Mounting with P2CF Panel Mounting Loosen the screws of the Flush Mounting Adapter, spread open the hooks, and remove the Mounting Adapter. When the Y92F-30, Y92F-70, Y92F-71 Mounting Adapter is used, press the hook inwards with the thumb and index finger of both hands, and press the Timer towards the front side. Duct Hook Panel P2CF-08 Panel Screw Y92F-30 Spread open the hooks to the left and right. Spread open the hooks to the left and right. Panel The illustration is an ex ample with the Y92F-70.
