On rising edge of up count signal, present count is reset to compensation value and, therefore, count inputs are accepted even if the compensation input is set to ON (not effective for down count signals.)

Resets batch count to zero and batch output turns OFF. Signals are taken in on the ON edge. Batch count signals are not accepted while batch count reset is ON.

Key protection indicator lit while key protection input is ON. Effective when power supply is turned off. Effective when protect terminals are shorted.

Outputs inhibit on the teaching mode.

Outputs made when batch counter is up to preset number of batches. Batch output remains ON until batch count reset goes ON. When the number of batches is set to zero, batch counting is performed but batch outputs are not made. Batch counter counts the number of completed counts to the preset for 1-stage models and to preset 2 for 2-stage models.

Changing Settings in the Function Setting Mode

1. Press the MODE Key to switch from run mode to setting mode.

• The Counter will continue operation if switched from run

mode to function setting mode during operation.

• The MODE Key will be locked if the key protection function is

enabled.

• Settings changed in the function setting mode are not

effective until run mode is entered. As the operating conditions will change in this case, always reset operation with the RESET Key or a reset input.

H7BR

3. Input a count signal corresponding to the conversion count value through the external sensor.

• The display on the right side indicates that an input of 50 counts

has been input from the external sensor with the controlled object moved 10 cm.

4. Perform prescale value teaching per count.

Press the TEACH Key. (Prescale value 0.2 = 10 cm/50)

• If the conversion count value input at step 3 is a negative value,

the prescale value will be calculated using the absolute value of the conversion count value.

• The fraction is rounded off for prescale calculations. (It is

rounded upward when displaying negative values.)

• While the TEACH Key is pressed, the teaching prescale value

(i.e., 0.2) is displayed.

Set Value 1 Teaching

1. Press the MODE Key to perform the teaching of set value 1, provided that the H7BR is a two-stage model.

2. Input an appropriate count signal from the external sensor.

3. Register the count value 250 as the set value, for example. Press the TEACH Key.

• The teaching set value is displayed while the TEACH Key is

pressed.

Set Value 2 Teaching (Two-stage Models Only)

• Perform the same procedure as Set Value 1 Teaching above.

5. When power is interrupted and the batch count output is ON, the output will be ON when power returns.

6. When a batch count set value which is greater than the present value is changed to a set value which is less than the present value, the output will go ON.

Precautions

Sensor Power Supply

• The capacity of the external power supply is 160 mA at 12

VDC/80 mA at 24 VDC switchable. When using a 24 VAC/12 to 24 VDC power supply type H7BR, reduce the load with the power supply voltage, as shown in the following diagram (When supplying external power).

160

Load current (mA)

1710 20 25

Supply voltage (VDC)

Power Supplies

• When turning the power ON and OFF, input signal reception is

possible, unstable, or impossible as shown in the diagram below. The unstable period will vary with power supply voltage, and the load conditions on external power supplies.

Power supply

Input impossible impossible

OFF

0 to 50 ms

10 ms

Possible

Unstable

• A switching regulator is used in the internal circuits of counters

with 100-to-240-VAC or 12-to-24-VAC specifications, causing an inrush current (approx. 1.5 A) to flow when power is turned on. If the capacity of the power supply to the counter is insufficient, the counter may not start operation. Be sure to provide adequate capacity (recommended supply capacity; 25 W min.)

• Connect the power supply voltage through a relay or switch in

such a way that the voltage reaches a fixed value immediately.

DIP Switch Setting Changes

Any changes in the DIP switch settings while power is being supplied is invalid. Restart the power supply.

Operating Environment

• When using the Counter in an area with much electronic noise,

separate the Timer, wiring, and the equipment which generates the input signals as far as possible from the noise sources. It is also recommended to shield the input signal wiring to prevent electronic interference.

• Organic solvents (such as paint thinner), as well as very acidic or

basic solutions might damage the outer casing of the Counter.

Using the Prescale Function

• When setting the prescale value, be sure that the set value

satisfies this equation: set value “max. value - prescale value’. (if the prescale value is 1,250, 999.999 - 1,250 = 998.749 max.)

• If a higher value is used, the output may be affected, so make

sure that the output is produced before starting operation.

Changing Set Values

• When changing the set value while the Counter is operating, the

output will be produced if the set value ever equals the present value. To avoid triggering the output, begin by incrementing a higher digit to a large number.

Resetting with a Set Value of 0

• When resetting is performed with the set value set to “0,” no

output will be given for the safety reasons once the reset is turned OFF (except for the H7BR-C).

Page 24

H7BR

Output Delay

• The following table shows the delay from when the present value

passes the set value until the output is produced. (The delay is the result of output control time, signal transmission time, relay switching time, etc.)

Actual measurements in N and K modes.

Control output

Contact output 1, 2 30 Hz {cps} 18 to 24 ms

Transistor output 1, 2 30 Hz {cps} 13.5 to 20 ms

Batch outputs 30 Hz {cps} 13.6 to 20.2 ms

*The variation in delays is due to different modes and conditions. For systems where the delay is a problem, take actual measurements under operating conditions.

Output delay*

Max. Count Speed of Batch Counter

• The maximum count speed of the batch counter is 1 kHz {cps}.

The batch counter counts the number of count-up times at the last stage (i.e., the number of preset-value counts if the H7BR is a one-stage model and the number of SET2 preset-value counts if the H7BR is a two-stage model). An interval of 1 ms or more is required before the batch counter counts up again after it has counted up.

Response Delay Time for Resetting

(Transistor Output)

• Take the following output delays into consideration after the

reset signal input is turned ON and the output is turned OFF.

Other

• When the Counter is installed in a control box and tests are

conducted which may damage the Counter’s internal circuitry (for example, a test measuring the maximum voltage difference between the control circuit and metal components), remove the Counter from the control box or short-circuit the terminals.
