WARNING J BEFORE USE This product has a built-in lithium battery. Do not short-circuit the + and -- terminals, charge, disassemble, deform, or expose the battery to fire. The battery may explode (break), catch fire, or cause liquid leakage. An insulation sheet has been inserted to maintain the quality of the Totalizer in the event of a long period without use. Be sure to remove this sheet before attempting to use the product. Remove the insulation sheet and press the Reset Key on the front panel of the Counter. (With the H7ET-N,-NV(-H),-NV1(-H), models, “0” or “0.0” will be displayed after 1 s.) ! Caution Do not use any battery other than the specified one (Y92S-36). Using another battery may cause liquid leakage or breakage, resulting in malfunction or injury. Insulation Sheet ! Caution If a voltage other than the rated one is applied, internal elements may be damaged. Do not use the Counter in the following places: • • • Reset Key Locations subject to direct sunlight. Switch settings on the Counter must be performed before mounting it to a control panel. Locations subject to corrosive gases. Locations subject to dust. Do not use the Counter in locations subject to: SSevere changes in temperature. SCondensation as the result of high temperatures. J MOUNTING PRECAUTIONS FOR PANEL- MOUNTING Although the operating section is watertight (conforming to NEMA 4, IP66), a rubber gasket is provided to avoid water leakage through the gap between the Counter and panel cutout. Unless this rubber gasket is tightly squeezed on, water may permeate inside the panel. For this reason, be sure to tighten the screws for fixing the panel-mounting bracket. Screw for the Panel-Mounting Bracket The wider side must face the panel. Panel 9 Adapter Adapter screw section 0.5 to 1 mm Tighten the screw until the distance is within the range shown above. H7ET H7ET J INPUT AND POWER SUPPLY The H7ET operates using a Battery. If the H7ET is connected to a device that has +V and OUT terminals that are connected with a diode as shown in the circuit diagram, the circuit indicated by the arrow 1 or 2 will be formed when the device is turned OFF. As a result, the H7ET may be reset or count by one. Such devices should not be connected to the H7ER. Do not apply voltage on the Counter if the Counter is a model that operates with no-voltage input, or the internal circuit of the Counter may be damaged. Do not connect any single input signal in parallel to Counter models operating with no-voltage input and those operating with voltage input, to avoid malfunction. Internal circuit J RESET INPUT AND COUNT INPUT When connecting a sensor to the Counter that operates with no-voltage input, make sure that the sensor has open collector output. Count input or reset input Sensor If an excessive voltage is applied to the count or reset input terminals, the internal elements may be damaged. Ensure that the following voltages are not exceeded: SPNP/NPN universal voltage input model: 30 VDC SAC/DC voltage input model: At count input: 240 VAC (peak voltage: 338V) 240 VDC At reset input: 3 VDC (no-voltage input) No-voltage input model: 3 VDC The operation of the Counter may be affected if the line voltage of the power supply exceeds 500 pF (about 10 m, with parallel wires of 2 x 2 mm). Keep all wires as short as possible. When using shielded wire, stray capacitance may occur. Do not remove the outer case when voltage is being applied to the power supply terminals or to the input terminals. When connecting an open collector input from a transistor to the Counter that operates with no-voltage input, make sure that the leakage current of the transistor is 5 µA maximum. The input for the H7Ej-NFV-j is a high-impedance circuit so influence from an induced voltage may result in malfunction. When the input signal wiring is longer than 10 m (stray capacitance of 120 pF/m, at room temperature), a CR filter or a bleeder resistor should be connected. When connecting count input from an SSR to the Counter that operates with AC/DC voltage input, use OMRON’s G3TA-IA or G3TA-ID SSR. Otherwise, make sure that the leakage current of the SSR is 0.1 mA maximum or connect a bleeder resistor in parallel to the input circuit of the Counter. or J COUNT INPUT OR RESET INPUT TO MORE THAN ONE H7ET COUNTER AT A TIME Leakage current: 0.1 mA max. or or PNP/NPN Universal DC Voltage Input *Bleeder resistor The voltage between terminals 1 and 2 must be 1.5 V maximum when the SSR is OFF. J BACKLIGHT POWER SUPPLY or To reduce variation in the brightness of the backlight when using more than one H7ET with a backlight, use the same power supply for all the backlights. or Note: H (Reset ON) level must be 4.5 V minimum. 4.7 (kΩ)/N + V H= 4.7 (kΩ)/N + R When connecting the DC power supply for the backlights, be sure to connect the polarities correctly. No-voltage Input J INPUT VERIFICATION WITH THE H7ET TIME COUNTER or The decimal point of the LCD blinks every other second while an input signal is being applied. If the decimal point is not blinking, the input signal is not being received correctly. Check the input signal connections. Note: 1. The leakage current of the transistor used for input must be less than 1 µA. 2. The forward voltage of the diode must be as low as possible (i.e., 0.1 V maximum with an IF of 20 µA) so the voltage between terminals 3 and 4 will be 0.5 V when the reset input is ON. 10 H7ET H7ET J UNIT LABEL FOR TIME COUNTER AND TACHOMETER J EN/IEC STANDARDS The counter input, reset input, and backlight power supply terminals of the no-voltage input or PNP/NPN universal DC voltage input models (H7Ej-N,-N1, H7Ej-NV(-H),-NV1(-H)) are not isolated. A unit label has been packed with the Counter. Use in accordance with the application. A SELV power supply conforming to Appendix H of IEC61010-1 should be used for the counter input, reset input and backlight power supply terminals. A SELV power supply is a power supply for which the input and output have double or reinforced insulation, and for which the output voltage is 30 Vrems with 42.4 V peak or 60 VDC max. (Only the H7Ej-NVj-H has a backlight.) J BATTERY REPLACEMENT The terminals for counter input and reset input for AC/DC multi-voltage input models have basic insulation. Remove the wiring when replacing the Battery. Do not come in contact with any item to which high voltage is being applied. Doing so may result in electric shock. Connect the reset input terminals to a device that does not have exposed current-carrying parts and has basic insulation for 240 VAC. Before changing the Battery, be sure that you are not carrying any static electric charge. Procedure for replacing the Battery (refer to the diagrams below): 1. Using the tool, pry open the lift-tab on the case. (1) 2. Pull the body out of its outer case. (2) 3. Lift the Battery up by the edge and remove it. (3) When removing the Battery, do not come in contact with the display area or any internal parts. 4. Wipe the back of the new Battery before inserting it. 5. Ensure that the + and -- terminals are correctly oriented. 6. After replacing the Battery, re-insert the body into its case. (4) Check that the case is securely held in by the lift-tab. 7. Press the Reset Key before use (not necessary for H7ET-N,-NV,-NV1). (5) When the internal Battery nears expiration, the display may flicker.
