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. Solid-state Timer H3BA-N 17 Operating Time Setting ■ Precautions for Correct Use When setting the operating time, do not turn the setting knob beyond its scale range. For precise time setting, conduct operation tests by Changing the Setting adjusting the setting knob. Do not change the time unit, time range, or operation mode while the The accuracy of the operating time of the Analog Timer is indicated Timer is in operation, otherwise the Timer may malfunction. 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 Connecting the Operating Power application will be able to use a time setting as close as the full-scale Supply time setting of the Timer. The H3BA-N@ contains a capacitor-drop power circuit. Use a Others sinusoidal power supply with a commercial frequency. Do not use power supplies with a high frequency component (such as inverter When conducting a dielectric test, impulse voltage test, or insulation power supplies) for Timers with 110 or 220-VAC specifications. Using resistance test between the electric circuit and non-current-carrying these power supplies can damage internal circuits. metal parts of the Timer mounted to a control panel, be sure to take If voltages other than the rated voltage is applied, the internal the following steps.

G, S, R Do not leave the Timer in time-up condition for a month or longer in Input terminal places with high temperatures, otherwise the internal parts, such as H3BA-N 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 Closed time-up condition for a long time. 2 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 Input/Output service life of the Timer. When the Timer is reset right after the Timer goes into time-up An appropriate input will be applied to the input signal terminals of condition, be sure to provide the Timer with an appropriate circuit the Timer when one of the input terminals (terminals 5, 6, and 7) and configuration considering the resetting time of the Timer so that a the common terminal (terminal 2) for the input signals are short- sequential error will not result. 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. 10 (See note 2) Power supply AC or DC H3BA-N 5, 6, 7 G, S, R Input contact Input terminal The Timer uses the constant value read method. Be careful when 2 (see note 1) changing the set value because the output of the Timer will be ON when the set value coincides with the count value. Note: 1. Power supply terminal 2 is a common terminal for the input Be sure that the casing of the Timer is free from organic solvents, signals (G, S, R) to the Timer. Never use terminal 10 as the such as paint thinner and benzene, strong acid, and alkali solvents, common terminal for this purpose, otherwise the internal which will damage the casing. circuit of the Timer may be damaged. 2. Do not connect a relay or any other load between these two Note: It is impossible to connect more than two Timers in parallel. points, otherwise the internal circuit of the Timer may be damaged due to the high-tension voltage applied to the input terminals. 18 Solid-state Timer H3BA-N When using the US08, be sure to use 10.5-dia. max. multi-conductor ■ Mounting 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 Surface Mounting coating is too thick and the hooks do not click, spread open the There is no particular restriction on surface mounting directions, but hooks appropriately to the left and right after inserting the Timer to be sure that the Timer is securely mounted horizontally. the hole. Spread open the hooks to the left and right. P2CF Socket Panel 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. The illustration is an ex ample with the Y92F-70. Duct Hook Spread open the hooks to the left and right. P2CF-08 ■ Dismounting Surface Mounting with P2CF Panel 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 Panel Mounting by hand. Loosen the screws of the Flush Mounting Adapter, spread open the hooks, and remove the Mounting Adapter. Panel Mounting When the Y92F-30, Y92F-70, Y92F-71 Mounting Adapter is used, When the Y92F-30 Flush Mounting Adapter is used, insert the Timer press the hook inwards with the thumb and index finger of both into the square hole from the front side of the panel and put on the hands, and press the Timer towards the front side. 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.
