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 H7ER-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 Switch settings on the Counter must be performed before mounting it to a control panel. Locations subject to direct sunlight. Locations subject to corrosive gases. Do not use the Counter in locations subject to: SSevere changes in temperature. SCondensation as the result of high temperatures. Locations subject to dust. J MOUNTING PRECAUTIONS FOR FLUSH MOUNTING Although the operating section is watertight (conforming to NEMA4, IP66), rubber packing is provided to avoid water leakage through the gap between the Counter and panel cutout. Unless this rubber packing is tightly squeezed on, water may permeate inside the panel. For this reason, be sure to tighten the screws for fixing the Flush Mounting Bracket. Screw for the Flush 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. H7EC H7EC J RESET INPUT AND COUNT INPUT J COUNT INPUT OR RESET INPUT TO MORE THAN ONE H7E COUNTER AT A TIME Internal circuit The H7EC operates using its built-in Battery. If the H7EC 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 H7EC may be reset or count by one. It is recommended that such devices not be connected to the H7EC. PNP/NPN Universal DC Voltage Input or Count input or reset input If an excessive voltage is applied to the count or reset input terminals, the internal elements may be damaged. or 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 Note: H (Reset ON) level must be 4.5 V minimum. 4.7 (k)/N + V H= 4.7 (k)/N + R No-voltage Input Do not remove the outer case when voltage is being applied to the power supply terminals or to the input terminals. or 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. Note: 1. The leakage current of the transistor used for input must be less than 1 A. 2. The forward voltage of the diode must be as low as possible (i.e., 0.1 V maximum with an IF of 20 A) so the voltage between terminals 3 and 4 will be 0.5 V when the reset input is ON. 10 H7EC H7EC J INPUT AND POWER SUPPLY J BATTERY REPLACEMENT Do not apply voltage on the Counter if the Counter is a model that operates with no-voltage input, to avoid damaging the internal circuit of the Counter. Do not connect any single input signal in parallel to Counter models operating with no-voltage input and those operating with voltage input, otherwise the Counters may malfunction. 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. When connecting a sensor to the Counter that operates with no-voltage input, make sure that the sensor has open collector output. Procedure for replacing the Battery (refer to the diagrams below): Sensor 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. Before changing the Battery, be sure that you are not carrying any static electric charge. 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 H7ER-N,-NV,-NV1). (5) When the internal Battery nears expiration, the display may flicker. 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 A maximum. (1) 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. (2) Tool (1) (3) or Leakage current: 0.1 mA max. or (4) or *Bleeder resistor The voltage between terminals 1 and 2 must be 1.5 V maximum when the SSR is OFF. (5) J BACKLIGHT POWER SUPPLY To reduce variation in the brightness of the backlight when using more than one H7E with a backlight, use the same power supply for all the backlights. 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 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.) When connecting the DC power supply for the backlights, be sure to connect the polarities correctly. The terminals for counter input and reset input for AC/DC multi-voltage input models have basic insulation. Connect the reset input terminals to a device that does not have exposed current-carrying parts and has basic insulation for 240 VAC. 11 H7EC H7EC NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS.
