Features Basic Features Safety and Reliability Ultra Short Body Isolated Power Supply and Input Circuits The body depth has been greatly reduced. Helps in making thinner control panels. Power supply circuit and input circuits are isolated inside the Counter/ Tachometer. Previous non-isolated counters had wiring restrictions 12 to 24-VDC Models with Screw Terminals: 59 mm and could be damaged if wired incorrectly. The H7CX removes these 100 to 240-VAC Models with Screw Terminals: 78 mm* Models with Sockets: 63.7 mm (case dimension) worries. * Power supply circuit and input circuits are isolated for safety and reliability. Note: Except 12 to 24-VDC models. Set Value Limit You can set an upper limit for the set value to prevent unexpected operation of output devices caused by setting mistakes. Previous New models models Easier to Read For better readability, the character height for the present value display is 12 mm on models with 4 digits, the largest class in the industry. The wide viewing angle and brightness provide excellent visibility.

Total Reset or Reset 2 • The total count value is reset when the total reset/reset 2 input is turned ON.

The total 0 count value returns to 0 when it reaches the full Note: The full scale (FS) for H7CX 4-digit models is 9999. 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 is Reset 2 (batch input. counter reset) • When the batch counter reset input is turned Set value ON, the batch count value is reset, and batch Present value output turns OFF. 0 • If the Reset Key is pressed while the batch count value is displayed, the batch count value OUT2 is reset and batch output turns OFF. The Batch count set value present value is also reset at this time.

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. 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. (1) Dual Count Calculating Mode = ADD (2) Dual Count Calculating Mode = SUB • The operation after count completion for the Dual count value = CP1 PV + CP2 PV Dual count value = CP1 PV − CP2 PV dual counter value is determined by the output mode.

Note: The above is for when the output mode is N. 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 models), FFFFFF (FFFF for 4-digit models) will be displayed to indicate an overflow, and all counting will stop. 25 H7CX-A@-N Counter Twin Counter Operation Two independent counters are built in.

Soft Cover Y92A-48F1 Waterproof Packing Y92S-29 Protecting the Timer in Environments Subject to Oil The H7CX's panel surface is water-resistive (conforming to IP@6, UL Type 4X) and so even if drops of water penetrate the gaps between 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 Order the Waterproof Packing separately if it is lost or damaged. protection equivalent to IP54 against oil. Do not, however, use the The Waterproof Packing can be used to achieve protection equivalent H7CX in locations where it would come in direct contact with oil. to IP66. (The Waterproof Packing will deteriorate, harden, and shrink Hard Cover depending on the application environment. To ensure maintaining the Y92A-48 NEMA4 waterproof level, periodically replace the Waterproof Packing. The periodic replacement period will depend on the application environment. You must confirm the proper replacement period. Use 1 year or less as a guideline. If the Waterproof Packing is not replaced periodically, the waterproof level will not be maintained.) It is not necessary to mount the Waterproof Packing if waterproof construction is not required. Connection Sockets Refer to Connection Sockets on page page 13 for details.

If the panel screws are tightened unequally, water may enter the panel. • Store the Counter at the specified temperature. If the Counter has been stored at a temperature of less than −10°C, allow the Counter to stand at room temperature for at least 3 hours before use. • Mounting the Counter side-by-side may reduce the life expectancies of internal components. • Use the Counter within the specified ranges for the ambient operating temperature and humidity. • Do not use in the following locations: • Locations subject to sudden or extreme changes in temperature. • Locations where high humidity may result in condensation. • Do not use the Counter outside of the rated ranges for vibration, shock, water exposure, and oil exposure. • Do not use this Counter in dusty environments, in locations where corrosive gasses are present, or in locations subject to direct sunlight. • Install the Counter well away from any sources of static electricity, such as pipes transporting molding materials, powders, or liquids. 52 H7CX-@-N • Attach the front panel when using the Counter.

Always check the wiring sufficiently before use. • An inrush current of approx. 10 A will flow for a short time when the power supply is turned ON. If the capacity of the power supply is not sufficient, the Counter may not start. Be sure to use a power supply with sufficient capacity.

Unexpected operation resulting in property damage or accidents may occur if the settings are not appropriate. • Do not leave the Counter for long periods at a high temperature with output current in the ON state. Doing so may result in the premature deterioration of internal components (e.g., electrolytic capacitors). • EEPROM is used as backup memory when the power is interrupted. The write life of the EEPROM is 100,000 writes.
