**Note:** Depending on the operating environment, the condition of resin parts may deteriorate, and may shrink or harden. Therefore, it is recommended that resin parts are replaced regularly.
**Product Protection for Use in Environments Subject to Water or Oil** The panel surface has a protective structure so that the internal circuits will not be adversely affected if drops of water penetrate the gaps between the keys. If, however, there is a possibility of water or oil being present on the operator's hands, mount the optional Soft Cover. The Soft Cover ensures protection equivalent to IP54. Do not, however, use the H7BX in locations where it would come into direct contact with oil.

**H7BX**
## **Explanation of Functions**
## **Settings marked with a star can be performed with the DIP switch.**
## • **Input Mode (** cntm **)** ★
Set increment mode (UP), decrement mode (DOWN), or one of the increment/decrement modes (UP/DOWN A, UP/DOWN B, or UP/ DOWN C) as the input mode. Input modes other than UP or DOWN modes cannot be set using the DIP switch. Use the operation keys if other modes are required. (For details on the operation of the input modes, refer to _Input Modes and Present Value_ on page 13.)
## • **Dual Count Calculating Mode (** calm **)**
When the H7BX using as a dual counter, select either ADD (addition) or SUB (subtraction) as the calculation method for the dual count value.
ADD: Dual count value = CP1 PV + CP2 PV
SUB: Dual count value = CP1 PV − CP2 PV
## • **Output Mode (** outm **)** ★
Set the way that control output for the present value is output. The possible settings are N, F, C, R, K-1, P, Q, A, K-2, D, L, and H. Output modes other than N, F, C, or K-1 cannot be set using the DIP switch. Use the operation keys if other modes are required. The output modes that can be set vary with the model. (For details on the operation of the output modes, refer to _Input/Output Mode Settings_ on page 14.)
## • **One-shot Output Time (** otim **)** ★
Set the one-shot output time (0.01 to 99.99 s) for the control output. A one-shot output can be used only when C, R, K-1, P, Q, A, or K-2 is selected as the output mode. Output times other than 0.5 s or 0.05 s cannot be set with the DIP switch. Use the operation keys if other settings are required.
## • **Reset Input Signal Width (** iflt **)** ★
Set the reset input signal width (20 ms/1 ms) for reset/reset 1 and total reset/reset 2 inputs together. If contacts are used for input signals, set the counting speed to 20 ms. Processing to eliminate chattering is performed for this setting.
## • **Decimal Point Position (** dp **)**
Decide the decimal point position for the present value, CP1/CP2 present values, set values (SV1, SV2), total count value, dual count value and dual count set value.
## • **Prescale Value (** pscl **)**
Pulses input to the counter are converted according to the specified prescale value.
Setting range: 0.001 to 99.999
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).

## • **One-shot Output 2 Time (** otm2 **)** ★
When the H7BX using as a 2-stage counter or batch counter, set the one-shot output time (0.01 to 99.99 s) for control output (OUT2). A one-shot output can be used only when C, R, K-1, P, Q, A, or K-2 is selected as the output mode. Output times other than 0.5 s or 0.05 s cannot be set with the DIP switch. Use the operation keys if other settings are required.
## • **One-shot Output 1 Time (** otm1 **)**
When the H7BX using as a 2-stage counter, set the one-shot output time (0.01 to 99.99 s) for control output (OUT1). A one-shot output can be used only when D, L, or H is selected as the output mode. If the output time is set to 0.00, hold is displayed, and outputs are held.
## • **Counting Speed (** cnts **)** ★
Set the maximum counting speed (30 Hz/5 kHz) for CP1 and CP2 inputs together. If contacts are used for input signals, set the counting speed to 30 Hz. Processing to eliminate chattering is performed for this setting.
**Note:** Incorrectly setting the prescale value will result in counting errors. Check that the setting has been performed correctly before using the H7BX.
## • **NPN/PNP Input Mode (** imod **)**
Select either NPN input (no-voltage input) or PNP input (voltage input) as the input format. For 2-wire sensors, set the format to NPN input. The same format setting applies to all external inputs. For information on input connections, refer to page 6.
## • **Display Color (** colr **)**
Set the color used for the present value.
||**Output OFF ***|**Output ON ***|
|---|---|---|
|red|Red (fixed)||
|grn|Green (fixed)||
|r-g|Red|Green|
|g-r|Green|Red|
*When the H7BX using as a 2-stage counter, this is the status of output 2.
## • **Key Protect Level (** kypt **)**
Set the key protect level.
For details, refer to _Key Protect Level_ on page 24.

**H7BX**
## **Total and Preset Counter Operation**
The H7BX has a total counter separate from the 1-stage preset counter for counting the total accumulated value.
- The total counter continues to count the total
- Reset/reset 1 accumulated value when the present value is reset using reset/reset 1 input (Reset Key).
- • The total count value is reset when the total
- Total reset/reset 2 reset/reset 2 input is turned ON. Present value If the Reset Key is pressed while the total 0 count value is displayed, the total count
- 999999 value is reset. The present value is also reset at this time.
- Total count value • The counting range of the total counter is −
- 0 99,999 to 999,999. The total count value
- The counting range of the total counter is − 99,999 to 999,999. The total count value
- returns to 0 when it reaches the full scale limit.
## **Batch Counter Operation**
The H7BX has a batch counter separate from the 1-stage preset counter for counting the number of times the count has been completed.

**H7BX**
## **Explanation of Functions**
## **Settings marked with a star can be performed with the DIP switch.**
## • **Tachometer Output Mode (** totm **)** ★
Set the output method for control output based on the OUT1/OUT2 set value. Upper and lower limit (HI-LO), area (AREA), upper limit (HI-HI), and lower limit (LO-LO) can be set. (For details on the operation of the output modes, refer to _Output Mode Settings_ on page 22.)
## • **Counting Speed (** cnts **)** ★
Set the maximum counting speed (30 Hz/10 kHz) for CP1 input. If contacts are used for input signals, set the counting speed to 30 Hz. Processing to eliminate chattering is performed for this setting.
## • **Decimal Point Position (** dp **)**
Decide the decimal point position for the measurement value, OUT1 set value, and OUT2 set value.
## • **Prescale Value (** pscl **)**
It is possible to display the rate of rotation or the speed of a device or machine to which the H7BX is mounted by converting input pulses to a desired unit. If this prescaling function is not used, the input frequency (Hz) will be displayed.
The relationship between display and input is determined by the following equation. Set the prescale value according to the unit to be displayed.
Displayed value = f × α
f: Input pulse frequency (number of pulses in 1 second)
α: Prescale value
## 1. Displaying the Rotation Rate
|**Display unit**|**Prescale value (**α**)**|
|---|---|
|rpm|1/N×60|
|rps|1/N|
N: Number of pulses per revolution
Example: In order to display the rate of rotation for a machine that outputs 5 pulses per revolution in the form @@.@ rpm: 1. Set the decimal point position to 1 decimal place.
2. Using the formula, set the prescale value to 1/N × 60 = 60/5 = 12.
## 2. Displaying the Speed
|**Display unit**|**Prescale value (**α**)**|**Prescale value (**α**)**|**Prescale value (**α**)**|
|---|---|---|---|
|m/min|πd×1/N×60|||
|m/s|πd×1/N|||
|N: Number of pulses per revolution<br>d: Diameter of rotating body (m)<br>πd: Circumference (m)|||d: Diameter<br>of rotating<br>body|
|||||
Note: Incorrectly setting the prescale value will result in counting errors. Check that the setting has been performed correctly before using the H7BX.
## • **Average Processing (** aug **)** ★
Flickering display and output chattering can be prevented by using average 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.
## • **Auto-zero Time (** avt **)** ★
It is possible to set the H7BX so that if there is no pulse for a certain time the display is force-set to 0. This time is called the auto-zero time. Set the auto-zero time to a time slightly longer than the estimated interval between input pulses. It will not be possible to make accurate measurements if the auto-zero time is set to a time shorter than the input pulse cycle. Setting a time that is too long may also result in problems, such as a time-lag between rotation stopping and the alarm turning ON.
## • **Startup Time (** stmr **)**
In order to prevent undesired output resulting from unstable input immediately after the power supply is turned ON, it is possible to prohibit measurement for a set time. This time is called the startup time.
It can also be used to stop measurement and disable output until the rotating body reaches the normal rate of rotation, after the power supply to the H7BX and rotating body are turned ON at the same time.

## • **NPN/PNP Input Mode (** imod **)** ★
Select either NPN input (no-voltage input) or PNP input (voltage input) as the input format. Select an NPN input when using a 2-wire sensor. The same setting is used for all external inputs.
For details on input connections, refer to Input Connections on page 6.
## • **Display Color (** colr **)**
Set the color used for the measurement value.
||**Control output OFF**|**Control output ON**|
|---|---|---|
|red|Red (fixed)||

- *2.If the tachometer output mode is set to AREA, however, the measured value is displayed in green when control output 1 is OFF and in red when control output 1 is ON.
## • **Key Protect Level (** kypt **)**
Set the key protect level.
For details, refer to _Key Protect Level_ on page 24.
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 processing enables fluctuating input signals to be displayed stably. Set the optimum number of times for the application.

**H7BX**
## **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.**
**Fire may occasionally occur. Tighten the terminal screws to a torque of 0.5 to 0.6 N·m (4.4 to 5.3 in-lb).**
**Minor injury due to explosion may occasionally occur. Do not use the H7BX where subject to flammable or explosive gas.**
**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.**
**Minor electric shock, fire, or malfunction may occasionally occur. Never attempt to disassemble, modify, or repair the H7BX or touch any of the internal parts.**
## **Precautions for Safe Use**
## **Operating Environment**
- The H7BX is intended for indoor use only. Do not use the H7BX outdoors or in any of the following locations.
- Locations subject to sudden or extreme changes in temperature.
- Locations where high humidity may result in condensation.
- Locations subject to direct sunlight.
- Locations subject to corrosive gas.
- Locations subject to excessive dust or dirt.
- This is a class A product (for industrial environments). In residential areas, it may cause radio interference, in which case the user may be required to take adequate measures to reduce interference.
- Use the H7BX within the specified ratings for operating temperature and humidity. Temperature rise may shorten the service life of H7BX if it is used near a power supply or other heat-generating objects.
- Use the H7BX within the specified ratings for vibration, shock, and splashing water.
- The H7BX is not oil resistant. Do not use it in locations subject to oil.
- Install the H7BX well away from any sources of excessive static electricity, such as pipes transporting molding materials, power, or liquids.
- Store the H7BX within the specified ratings. If the H7BX has been stored at temperatures of −10°C or lower, let it stand for 3 hours or longer at room temperature before turning ON the power supply.
## **Power Supply**
- Maintain voltage fluctuations in the power supply within the specified range.
- Use a commercial power supply as the AC power supply for the H7BX. Using an inverter output with an output frequency of 50/60 Hz as the power supply may cause the H7BX to produce smoke or become damaged by burning.
- Use a switch, relay, or other device with contacts so that the rated power supply voltage will be reached within 2 s. If the power supply voltage is not reached quickly enough, the outputs may malfunction.
- Use a switch, relay, or other device with contacts so that the rated power supply voltage will be reached within 2 s. If the power supply voltage is not reached quickly enough, the outputs may malfunction.
## **Installation and Wiring**
- To mount the H7BX to a panel, attach the two supplied adapters to the left and right sides of the H7BX, and securely tighten the knurled screws on the adapters by hand, maintaining a balance between them. Damage may result if the knurled screws are excessively tightened with pliers or other tools.
- Be sure to wire the terminals correctly.
- Up to two wires of the same size and type can be inserted into a single terminal.
- Do not connect more than two crimp terminals to each H7BX terminal.
- Use the specified wires for wiring.
- Applicable wire: AWG 24 to AWG 18 (equal to a cross-sectional area of 0.20 to 0.82 mm[2] ) Solid wire or twisted wire (copper), operating temperature over 70°C.
- Separate the H7BX, the devices that generate input signals, and input signal wires from any potential sources of noise, such as high-voltage lines.
## **Handling**
- Do not use organic solvents (such as paint thinner or benzine), strong alkaline, or strong acids because they will damage the external finish.
- Approximately 14 V will be output to the input terminals when the H7BX is used with the key protection input terminals and no-voltage input (NPN input) is used. To prevent charging accidents, connect a diode to the power supply circuit of input devices if input devices are used with a power supply of less than 14 V.
- Do not connect loads that exceed the rated output current. The output elements may be destroyed, possibly resulting in short-circuit or open-circuit faults.
- When using heaters, be sure to use a thermal switch for the load circuit.
- Always connect a diode to protect against counter electromotive force when using an inductive load. H7BX electromotive force may destroy output elements, possibly resulting in short-circuit or open-circuit faults.
- Install a switch or circuit breaker that allows the operator to immediately turn OFF the power, and label it to clearly indicate its function.
- Check that the display (backlight and LCD) is operating normally. Some operating environments may accelerate deterioration of the indicators, LCD, and resin components and cause display malfunctions. Periodically inspect and replace parts.
- Internal elements may be destroyed if a voltage beyond the rated voltage is applied.
- When the power is turned ON, an inrush current will flow for a short time (approx. 10 A for 2 ms). Depending on the power supply capacity, operation may not start. Be sure to use a power supply with a sufficient capacity.

## **Precautions for Correct Use**
- Inrush current generated by turning ON or OFF the power supply may deteriorate contacts in the power supply circuit. Turn ON or OFF using a device with a rated current of 10 A or higher.
- Input signals may be accepted, not accepted, or unstable for the following time when the power supply is turned ON or OFF. Set the system to allow leeway in the timing of input signals.
Power supply[ON] OFF 200 ms 0 to 90 ms 5 ms 0 to 1 s Input Impossible stableUnPossible Unstable Impossible
- This H7BX always compares the count value with the set value. Thus, if you change the set value during operation, please remember that the output will turn ON when the set value becomes equal to the count value.
- With the factory setting, the output will turn ON when power is supplied to the H7BX because the set value and count value are both zero. While resetting, however, the output stays OFF.
- EEPROM is used as memory when the power is interrupted. The write life of the EEPROM is 100,000 writes. The EEPROM is written when settings are changed, or the power is tuned OFF.
- Water resistance will be lost if the front sheet is peeled off or torn. Do not use the H7BX if the front sheet is missing or torn.
- Abide by all local ordinances and regulations when disposing of the H7BX.
- External Power Supply
Reduce the load current as shown in the diagram on the right according to the power supply voltage if a DC power supply is used for models specified for 24 VAC/12 to 24 VDC.
