Panel 9 H7EC H7EC J RESETINPUTANDCOUNTINPUT J COUNTINPUTORRESETINPUTTO MORETHANONEH7ECOUNTERAT The H7EC operates using its built-in Battery. If the H7EC is ATIME connected to a device that has +V and OUT terminals that are connected with a diode as shown in the circuit diagram, the PNP/NPN Universal DC Voltage Input 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. or Count input or reset input or 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 Note: H (Reset ON) level must be 4.5 V minimum. SAC/DC voltage input model: 4.7 (kΩ)/N + V H= At count input: 240 VAC (peak voltage: 338V) 4.7 (kΩ)/N + R 240 VDC No-voltage Input At reset input: 3 VDC (no-voltage input) No-voltage input model: 3 VDC Do not remove the outer case when voltage is being applied to or the power supply terminals or to the input terminals. 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 Note: 1. The leakage current of the transistor used for input capacitance of 120 pF/m, at room temperature), a CR filter or a must be less than 1 µA. bleeder resistor should be connected. 2. The forward voltage of the diode must be as low as possible (i.e., 0.1 V maximum with an I of 20 µA) so F the voltage between terminals 3 and 4 will be 0.5 V when the reset input is ON. 10 Internal circuit H7EC H7EC J INPUTANDPOWERSUPPLY J BATTERYREPLACEMENT Do not apply voltage on the Counter if the Counter is a model Remove the wiring when replacing the Battery.

Ensure that the + and -- terminals are correctly oriented. 6. AfterreplacingtheBattery,re-insertthebodyintoitscase.(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) The operation of the Counter may be affected if the line voltage of the power supply exceeds 500 pF (about 10 m, with parallel When the internal Battery nears expiration, the display may wires of 2 x 2 mm). Keep all wires as short as possible. When flicker. using shielded wire, stray capacitance may occur. When connecting an open collector input from a transistor to the (2) (1) Tool Counter that operates with no-voltage input, make sure that the leakage current of the transistor is 5 µA maximum. 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 (1) parallel to the input circuit of the Counter.

(5) J BACKLIGHTPOWERSUPPLY J EN/IECSTANDARDS To reduce variation in the brightness of the backlight when using more than one H7E with a backlight, use the same power supply The counter input, reset input, and backlight power supply for all the backlights. 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 When connecting the DC power supply for the backlights, be for which the input and output have double or reinforced sure to connect the polarities correctly. 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.) 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:DIMENSIONSSHOWNAREINMILLIMETERS.Toconvertmillimeterstoinchesdivideby25.4.
