Depending on the operating environment, the condition of Hard Cover Soft Cover resin products may deteriorate, and may shrink or become Y92A-48 Y92A-48F1 harder. Therefore, it is recommended that resin products are replaced regularly. 2. The H7CX’s panel surface is water-resistive (conforming to IP66) and so even if drops of water penetrate the gaps be- tween the keys, there will be no adverse effect on internal circuits. If, however, there is a possibility of oil being present on the operator’s hands, use the Soft Cover. The Soft Cover ensures protection equivalent to IP54 against oil. Do not, however, use the H7CX in locations where it would come in direct contact with oil. Flush Mounting Adapter Waterproof Packing (provided with screw-terminal models) (provided with screw-terminal models) Y92F-30 Y92S-29 When using the Y92S-29, the degree of protection for the H7CX's panel surface conforms to NEMA4, UL Type 4X, and IP66.

If there is power failure while output is ON, output will turn ON again when the power supply has recovered. For one-shot output, output will turn ON again for the duration of the output time setting once the power supply has recovered. 4. Do not use the counter function in applications where the count may be completed (again) while one-shot output is ON. 26 H7CX-A Total and Preset Counter Operation The H7CX has a total counter, separate from the 1-stage preset counter, for counting the total accumulated value.  The total counter continues to count the Reset/reset 1 total accumulated value when the present value is reset using reset/reset 1 input (reset key). Total reset/reset 2  The total count value is reset when the Present value total reset/reset 2 input is turned ON. If the 0 reset key is pressed while the total count value is displayed, the total count value is 999999 reset. The present value is also reset at Total count value this time.  The counting range of the total counter is 0 −99,999 to 999,999 (−999 to 9,999). The Note: The full scale (FS) for H7CX 4-digit models is 9999. total count value returns to 0 when it reaches the full scale limit. Batch Counter Operation The H7CX has a batch counter, separate from the 1-stage preset counter, for counting the number of times the count has been completed.  The batch counter continues after count Reset 1 completion.  Batch output is held until batch counter Reset 2 (batch reset is input. counter reset)  When the batch counter reset input is turned ON, the batch count value is reset, Set value and batch output turns OFF. Present value  If the reset key is pressed while the batch 0 count value is displayed, the batch count value is reset and batch output turns OFF. The present value is also reset at this time. OUT2  Although the count value can be incre- Batch count set value mented and decremented, the batch count (Sub-display) is only incremented. 2 Batch count value 1 (Main display) 0 OUT1 (batch output) Note: The above is for when the output mode is C. Note: 1. The batch count value is held at 0 during batch counter reset input. 2. If the batch count set value is 0, batch count will be performed but there will be no batch output. 3. The batch count value returns to 0 when it reaches 999,999 (9,999 for 4-digit models). 4. Once batch input has been turned ON, it will return to the ON state after power interruptions. 5. If the batch count set value is changed from a value that is greater than the batch count value to one that is less, batch output will turn ON. 6. After batch output turns ON, the ON state will be held even if the batch count set value is changed to a value greater than the batch count value. 27 H7CX-A Dual Counter Operation Using the dual counter allows the count from 2 inputs to be added or subtracted and the result displayed. It is possible to specify a set value for which output turns ON when the set value matches the added or subtracted result. OUT1 and OUT2 turn ON and OFF simultaneously.  The operation after count com- Dual Count Calculating Mode = ADD Dual Count Calculating Mode = SUB pletion for the dual counter Dual count value = CP1 PV + CP2 PV Dual count value = CP1 PV − CP2 PV value is determined by the out- put mode. Reset 1 Reset 1  The CP1 present value is reset (CP1 reset) (CP1 reset) when reset 1 input is turned Reset 2 Reset 2 ON and the CP2 present value (CP2 reset) (CP2 reset) is reset when reset 2 input is Dual count value turned ON. Dual count set value  If the reset key is pressed while Dual count set value Dual count value the dual count value, CP1 0 present value, or CP2 present 0 value is displayed, all of the CP1 present value present values are reset and CP1 present value outputs turn OFF. At this time, 0 counting is not possible for 0 CP1 or CP2 inputs. CP2 present value CP2 present value 0 0 OUT1, 2 OUT1, 2 Note: The above is for when the output mode is N. Note: The above is for when the output mode is K-2. SUB mode can be used only when K-2, D, L, or H is selected as the output mode with 6-digit models. Note: 1. Counting is not possible for CP1 during reset 1 input. CP2 will not be affected. The dual count value will be calculated based on a CP1 present value of 0. 2. Counting is not possible for CP2 during reset 2 input. CP1 will not be affected. The dual count value will be calculated based on a CP2 present value of 0. 3. The counting range for the dual count value is −99,999 to 999,999 (0 to 9,999 for 4-digit models). The counting ranges for the CP1 present value and CP2 present value are 0 to 999,999 (0 to 9,999 for 4-digit models). If a present value exceeds 999,999 (9,999 for 4-digit mod- els), FFFFFF (FFFF for 4-digit models) will be displayed to indicate an overflow, and all counting will stop. 28 H7CX-A Reset Function List Function 1-stage/2-stage Total and preset counter Batch counter Dual counter counter Screen dis- Present value/ Present value/ Total count Present value/ Batch count Dual count CP1 present set value (1, 2) set value value set value value/batch value/dual value/CP2 played in run count set value count set value present value mode Reset/reset 1 Present value Present value and output reset.

For details, refer to page 36. Note: 1. Be sure to set pin 1 of the DIP switch to ON. If it is set to OFF, the DIP switch settings will not be enabled. 2. Changes to DIP switch settings are enabled when the power is turned ON. Advanced-Function Settings After making DIP switch settings for basic operations, advanced-functions (see note) can be added using the operation keys. For details, refer to page 31. Note: Advanced functions consist of decimal point position, prescale value, auto-zero time, startup time, display color, output allocation, and key protect level. 30 H7CX-A Settings for Advanced Functions Note: When using as a tachometer, switch to the tachometer configuration using the procedure given on page 36. Settings that cannot be performed with the DIP switch are performed with the operation keys. Note: 1. If the mode is switched to the function setting mode during operation, operation will Power ON continue. 2. Changes made to settings in function setting mode are enabled for the first time when the mode is changed to run mode. Also, when settings are changed, the counter is reset (measured values initialized and output turned OFF) on returning to run mode. For details on operations in run mode, refer to page 34. (See note 1.) (See note 2.) The characters displayed in reverse video are the initial values. When performing settings with operation keys only, set pin1 of the DIP switch to OFF (factory setting). If 3s min. 3s min. pin 1 of the DIP switch is set to ON, the setting items indicated by will not be displayed. Set each setting item using the keys.

Flickering display and output chattering can be prevented using aver- age processing (simple averaging). Average processing can be set to one of four levels: no average processing, 2 times (i.e., the average of 2 measurement values), 4 times, or 8 times. The measurement cycle will be equal to the sampling cycle (200 ms) multiplied by the average processing setting (i.e., the number of times). Average pro- cessing enables fluctuating input signals to be displayed stably. Set the optimum number of times for the application. 32 H7CX-A Output Allocation (otst) When using H7CX-AU@ models as 2-stage counter, each output can be flexibly allocated to either stage 1 or 2. Transistor output placed for SV1 and contact output for SV2 or vice verse, as in the following table.

Average processing can be set to one of four levels: no average processing, 2 times (i.e., the average Auto-zero Time (aut=) of 2 measurement values), 4 times, or 8 times. For 5 Hz or higher, It is possible to set the H7CX-R so that if there is no pulse for a cer- the measurement cycle will be equal to the sampling cycle (200 ms) tain time the display is force-set to 0. This time is called the auto-zero multiplied by the averaging setting (i.e., the number of times). For time. less than 5 Hz, the frequency will be measured when the input pulse comes. Average processing enables fluctuating input signals to be Note: Set the auto-zero time to a time slightly longer than the estimat- displayed stably.

The H7CX’s panel surface is water-resistive (conforming to NEMA 4, UL Type 4X, and IP66). In order to prevent the internal circuit ■ Precautions for Safe Use from water penetration through the space between the H7CX and operating panel, attach a waterproof packing between the H7CX and installation panel and secure the waterproof packing with the Operating and Storage Conditions Y92F-30 Flush-mounting Adapter.  Do not use in locations affected by excessive vibration or shock, or 0.5 to 1 mm in locations subject to exposure to water or oil. It is recommended that the space between  Do not use the product in locations subject to dust, corrosive the screw head and the adapter should be 0.5 to 1 mm. gases, or direct sunlight.  Separate the input signal devices, input signal cables, and the  Tighten the two mounting screws on the Adapter. Tighten them product from the source of noise or high-tension cables producing alternately, a little at a time, so as to keep them at an equal noise. tightness. If the panel screws are tightened unequally, water may ingress inside the panel.  Separate the product from the source of static electricity when using the product in an environment where a large amount of static electricity is produced (e.g., forming compounds, powders, or fluid materials being transported by pipe).  Organic solvents (such as paint thinner), as well as very acidic or basic solutions might damage the outer casing of the H7CX.  Use the product within the ratings specified for temperature and humidity.  Do not use the product in locations where condensation may occur due to high humidity or where temperature changes are severe.  Store at the specified temperature. If the H7CX has been stored at a temperature of less than –10°C, allow the H7CX to stand at room temperature for at least 3 hours before use. Usage Precautions  Make sure that the voltage applied is within the specified range, otherwise the internal elements of the counter may be damaged.  The load current must be within the rated current.  Ensure that the power is turned OFF before changing DIP switch settings. Changing DIP switch settings with the power turned ON may result in electric shock due to contact with terminals subject to high voltages.  Pay attention to terminal polarity to ensure correct wiring.  Make sure that the fluctuation of the supply voltage is within the permissible range.  Apply the power supply voltage through a relay or switch in such a way that the voltage reaches the rated value within 2 s. If the voltage is applied gradually, the power may not be reset or unstable output operations may result.  Set each set value to match the item being counted (or measured). Not matching the content of the set values with the counted (or measured) items may cause unexpected operations resulting in injury or damage to the equipment.  Leaving the H7CX with outputs ON at a high temperature for a long time may hasten the degradation of internal parts (such as electrolytic capacitors). Therefore, use the product in combination with relays and avoid leaving the product as long as more than 1 month with the output turned ON. 59 H7CX ■ Precautions for Correct Use External Power Supply The capacity of the external power supply is 100 mA at 12 V. When using a 24 VAC/12 to 24 VDC power supply, reduce the load with the power supply voltage, as shown in the following diagram (DC power supplies only). (DC voltage supply only) 100 20 10.8 15 Power supply voltage (VDC) Power Supplies  Turn the power ON and OFF using a relay with a rated capacity of 10 A minimum to prevent contact deterioration due to inrush current caused by turning the power ON and OFF.  Be sure that the capacity of the power supply is large enough, otherwise the H7CX may not start due to inrush current (reference value: approx. 10 A, 1.5 ms at 26.4 VAC) that may flow for an instant when the H7CX is turned ON. Power Failure Backup All data is stored in the EEPROM when there is a power failure. The EEPROM can be overwritten more than 100,000 times. EEPROM is overwritten when the power is turned OFF or when settings are changed. ■ Conformance to EN/IEC Standards  Specifications call for basic insulation between the power supply and input terminals, between the power supply and output terminals, and between the input and output terminals. (The H7CX- A@D is not insulated between the power supply and input terminals.)  Input and output terminals are connected to devices without exposed charged parts.  Input and output terminals are connected to devices with basic insulation that is suitable for the maximum operating voltage. 60 Load current (mA) H7CX Safety Precautions (H7CX-A) Response Delay Time When Resetting ■ Precautions for Safe Use (Transistor Output) Changing the Set Values The following table shows the delay from when the reset signal is input until the output is turned OFF. When changing the set value during operation, because the H7CX uses a constant read-in system, output will turn ON if the set value is (Reference values) equal to the present value. Minimum reset signal width Output delay time 1 ms 0.8 to 1.2 ms 20 ms 15 to 25 ms ■ Precautions for Correct Use Output Delay Time Power Supplies The following table shows the delay from when the present value When turning the power ON and OFF, input signal reception is passes the set value until the output is produced. possible, unstable, or impossible as shown in the diagram below.

Maximum Counting Speed for Batch NPN output PNP output Counter The maximum counting speed for batch counter operation is 5 kHz. The batch counter counts the number of times the count reaches the set value. Load Load + + Power for load Power for load The diode connected to the collector of the output transistor is used to absorb inverted voltage that is generated when an inductive load is connected to the H7CX. Counter Inductive load + Power for load Operation with a Set Value and Present Value of 0 If the set value and present value are both 0, output will turn ON. Output will turn OFF during reset. Using the Prescaling Function Observe the following points when setting a prescale value.  Set the set value to a value less than {Maximum countable value − Prescale value}. Example: If the prescale value is 1.25 and the counting range is 0.000 to 999.999, set the set value to a value less than 998.749 (= 999.999 − 1.25).  If the set value is set to a value greater than this, output will not turn ON. Note: Output will turn ON, however, if a present value overflow occurs (FFFFFF or FFFF).  Setting the prescale value incorrectly may result in incorrect counting operation. Be sure to set the prescale value correctly. 61 H7CX Safety Precautions (H7CX-R) ■ Precautions for Safe Use Changing the Measurement Value The H7CX-R uses a constant read-in system, so the output status is affected when the comparison values are changed during operation such that the present measurement value falls within the range of the upper- and lower-limit comparison values. Turning ON the Power using the Factory Settings When the power is turned ON using the factory settings, the output will turn ON after 999.9 s if no pulses are received as count input. ■ Precautions for Correct Use Comparison Value Settings In upper and lower limit output mode, if the comparison value setting is such that comparison value 1 ≥ comparison value 2, the output will always be ON. Using the Prescaling Function Setting the prescale value incorrectly may result in incorrect counting operation. Be sure to set the prescale value correctly. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
