New Product Digital Counter H7CZ Easy to Use and Easy to Read. Basic Features • Character height of 10 mm for better readability. Operation is simplified by the Up Key for each digit. Safety and Reliability Power supply circuit and input ci rcuits are isolated inside the Counter. Set value limit function prevents unexpected operation of output devices caused by setting mistakes. Output counter function helps in managing the service life of the Counter or the load. Other Features Waterproof, dust-proof struct ure (UL508 Type 4X and IP66). Key protection. Refer to Safety Precautions on page 17. Features Set Value Limit Basic Features You can set an upper limit for the set value to prevent unexpected Better Readability operation of output devices caused by setting mistakes. Character Height of 10 mm with a Wide Viewing Angle. Easy to read from the top, bottom, and sides. Clear 10 mm (actual size) Confirmation Setting the upper limit of the set value enables worry-free operation. The Easiest Operation Operation is simplified by the Up Key for No overflow each digit. For 1,000 pieces Output Counter The output counter counts the number of times the output turns ON Safety and Reliability (alarms can be displayed and the count can be monitored in increments of 1,000 operations). This counter is useful in managing Isolated Power Supply and Input Circuits the service life of the Counter or the load. Power supply circuit and input circuits are isolated inside the Counter. Other Features Previous non-isolated counters had wiring restrictions and could be damaged if wired incorrectly. The H7CZ removes these worries. Waterproof, Dust-proof Structure (UL508 Type 4X and IP66) Worry-free application is possible in locations subject to water. Note: When the Y92S-29 Waterproof Packing is used. Key Protection Select from any of seven protection patterns. Use the best one for the application. 1 H7CZ Model Number Structure Model Number Legend H7CZ-L@@ 12 1. External connections 2.

Processing to eliminate chattering is performed for this setting. The output ON count will be 1,000 times the displayed value. Decimal Point Position (dp) Decide the decimal point position for the present value. Prescale Value (pscl) Pulses input to the counter are converted according to the specified prescale value. (Setting range: 0.001 to 99.999 for 6-digit models.) Example: To display the feed distance for systems that output 25 pulses for a feed length of 0.5 m in the form @@.@@ m: 1. Set the decimal point position to 2 decimal places. 2. Set the prescale value to 0.02 (0.5 ÷ 25). 0.5 m 25 pulses Encoder  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.  Output will turn ON, however, if a present value overflow occurs (FFFFFF). Note: If the prescale value setting is incorrect, a counting error will occur. Check that the settings are correct before using this function. 12 H7CZ Operation in Run Mode Set values for each digit as required using the U Key.

Do not use organic solvents (such as paint thinners or benzine), strong alkali, or strong acids. They will damage the external finish. Precautions for Safe Use  Confirm that indications are working normally, including the LCD.  The panel surface of the H7CZ is water-resistant (conforming to The indicator, LCD, and resin parts may deteriorate more quickly NEMA4, IP66, UL Type 4X (Indoor Use Only).

When mounting the Counter to a panel, tighten the two mounting screws alternately, a little at a time, so as to keep them at an equal tightness. 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. 17 H7CZ Precautions for Correct Use Conformance to EN/IEC Standards • An inrush current of approx. 10 A will flow for a short time when the When conforming to EMC standards, refer to the information power supply is turned ON.

Connect the input and output terminals to devices that do not have Input Impossible Unstable Possible Unstable Impossible any exposed charged parts. Inrush current generated by turn ing ON or OFF the power supply may deteriorate contacts on the power supply circuit. Turn ON or OFF to a device with the rated current of more than 10 A. If the prescale value setting is inco rrect, a counting error will occur. Check that the settings are correct before using this function. Make sure that all settings ar e appropriate for the application. Unexpected operation resulting in property damage or accidents may occur if the settings are not appropriate. Do not leave the Counter for l ong 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. The EEPROM is written at the following times: When the power supply is turned OFF When switching from Configurat ion Selection Mode or Function Setting Mode to Run Mode Dispose of the product according to local ordinances as they apply. 18 Warranty and Application Considerations Read and Understand This Catalog Please read and understand this catalog before purchasing the products.
