Turn the screws on the mounting brackets counterclockwise to loosen them sufficiently. Attach the bottom mounting bracket first. After attaching the mounting brackets, turn the screws clockwise to tighten them sufficiently. When the screws are completely tightened, you will hear the threads disengage.

The polarities of the DC power supply terminals are as follows: Terminal 1: negative; terminal 2: positive 2. If there is excessive external noise, terminal 3 must be grounded to an appropriate place where the grounding resistance is 100 max. There will be a current leakage of 0.2 mA each from terminals 1 and 2 to terminal 3. 3. The open terminals cannot be used as relay terminals. 4. Insert surge absorbers between each of the power supply terminals and the ground terminal. If the ground terminal is not used, insert the surge absorbers between terminal 1 and terminal 2.

Input Conditions of the H7AN H: 5 to 30 V L: 0 to 2 V For contact inputs, the contact must have a switching capacity of 2.5 mA min. at 12 V. If a 680-W resistor (1/2 W) is used for R4, reliability will be improved. Sensor H7AN (+) (CP1) (CP2) Reset (-) R4 High level: Contact: ON Connections of Single Solid-state Inputs The following illustrations show how to connect a single solid-state input to digital counters connected in parallel. The H7AN has an input resistance of 4.7 kW. If the number of counters is N, the total input resistance will be 4.7/N kW. In this case, the high level input signal voltage can be calculated as follows: (4.7/N) x E/(4.7/N + R) Determine the value of E (V) and R (kW) so that the high level input signal voltage will be 5 to 30 VDC. +E( V ) R (K) 4.7/N (K) (-) 8 9 10 11 12 13 14 8 4.7 k H7AN 1 2 3 4 5 8 9 10 11 12 13 14 4.7 k 11 H7AN 6 7 1 2 3 4 5 6 7 N Connections of Single Contact Inputs The following illustrations show how to connect a single contact input to digital counters connected in parallel.

Power supply for load 16 H7AN Safety Precautions Refer to Safety Precautions for All Counters. !CAUTION Minor injury due to electric shock may occasionally occur. Do not touch any of the terminals while power is being supplied. Minor injury due to electric shock may occasionally occur. Do not touch the terminals for at least 1 minute after turning OFF the power supply. Minor injury due to explosion may occasionally occur. Do not use the H7AN where subject to flammable or explosive gas. Minor electric shock, fire, or malfunction may occasionally occur. Never attempt to disassemble, modify, or repair the H7AN or touch any of the internal parts. If the output relay is used beyond its life expectancy, its contacts may become fused or there may be a risk of fire. Use the output relay within its rated load and electrical life expectancy. The life expectancy of the output relay varies considerably according to its usage. Fire may occasionally occur. Tighten the terminal screws to a torque of 0.74 to 0.90 N*m. Do not allow metal fragments, lead wire scraps, or chips from processing during installation to fall inside the H7AN. Otherwise, minor electric shock, fire or malfunction may occasionally occur. Precautions for Safe Use * The H7AN is not waterproof or oil resistant. Do not use it in locations subject to water or oil. * The load current must be within the rated current. * Pay careful attention to polarity to avoid wrong connections when wiring the counter input terminals and reset input terminal. * Use a switch, relay, or other contact device so that the power is turned ON or OFF quickly. If the power supply voltage is not reached quickly enough, the H7AN may malfunction. * Use the specified wires for wiring. Applicable Wires: AWG24 to AWG18 (cross-sectional area of 0.205 to 0.823 mm2) * Do not connect more than two crimp terminals to the same terminal. * Do not connect anything to unused terminals. * Leaving the H7AN 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 with the output turned ON for a long period of time (e.g., a month or more). * The set value of the Preset Counter can be changed at any time during operation and the new set value will be used immediately. The output will turn ON whenever the set value equals the current count, so change the set value with care. (If a setting switch is accidentally touched during operation, the set value will be changed and the new set value will be used for operation. Always leave the front panel cover closed unless you are changing a setting.) * When removing the Counter body from the case, never touch the terminals or electronic components with your hands or subject them to shock. When inserting the body, do not allow electronic components to come in contact with the case. * Static electricity may destroy internal components. When removing the Counter body from the case, do not touch an electronic components other than the setting switches with your hands. * When changing the set value during operation, do not leave a switch set so that two numbers are visible at the same time. The set value will not be accurate. Push the buttons on the thumbwheel switches firmly. Precautions for Correct Use * Inrush current of approximately 23 A will flow for a short period of time when the power supply is turned ON. If the capacity of the power supply is insufficient, the H7AN may not start. Use a power supply, breakers, an contacts with sufficient capacity. * After turning ON the power supply, 50 ms is required for the internal circuits to reach the operating voltage. Operation for input signals may not be correctly during this time. * After turning OFF the power supply, 50 ms is required for voltage in the internal circuits to drop. Operation may be performed for input signals during this time. H7AN V CP2 10 Reset 9 Polarity not reversible ON OFF 50 ms 11 CP1 30 VDC max.

Be sure to enable the backup function. 17 H7AN * The following timing chart shows how the H7AN indicates when there is an external or manual reset input. ON OFF Reset ON Reset indicator OFF Count display Display before reset Display after reset Off * To mount the casing on the digital counter, insert the digital counter body into the casing by hand as far as possible and then tighten the mounting screw. Press by the hand the front panel as indicated by the arrow so that the screw will tighten securely. Retaining Data during Power Interruptions Data is written to EEPROM when the power is turned OFF. The write life is 1,000,000 writes min. Self-diagnosis The following indications will be made when an error occurs. 7-segment display Reset indicator Count-out indicator Error Output status e1 OFF OFF CPU error OFF e2 OFF OFF RAM memory error OFF e3 OFF OFF EEPROM memory error OFF Try correcting the error by cycling the power supply. If the indications do not change, try inputting the reset signal. If that does not work, the Counter will need to be repaired. If normal operation is recovered, it might have been caused by noise. Check for noise generation. Changes in Specifications This product was upgraded in January 2006. The main changes are described below. 1. Maximum Counting Speeds A DIP switch on models with 4, 6, or 8 digits could be used to set the maximum counting speed to 3 kHz, 5 kHz, or 30 kHz. The upgraded models have been changed so the maximum counting speed can be set to 5 kHz or 30 kHz. 2. Addition of Setting to Enable/Disable Data Backup for Power Interruptions On models that back up data when power is turned OFF (models with model numbers ending in "-M"), a DIP switch setting has been provided to enable or disable backup. 3. Changes in Functions Allocated to Function Setting Switches Some of the functions allocated to the DIP switches have been changed to allow for the changes described in 1 and 2, above. 18 H7AN ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
