I/O Functions
Inputs CP1/CP2 Count signal inputs.
Up, Down, and Up/Down (command, individual, or quadrature) inputs accepted.
Reset Resets present value. (to zero in Up modes, to preset with 1-stage models in Down mode, and
to preset with 2-stage models.)
Count inputs are not accepted while reset input is ON.
Reset indicator lit while reset input is ON.
Compensation input
(±Range type)
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.)
Batch count reset
(Standard type)
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 Makes keys inoperative according to key protection level.
Key protection indicator lit while key protection input is ON.
Effective when power supply is turned off.
Effective when protect terminals are shorted.
Gate Inhibits counter operation when gate input is ON.
Outputs OUT 1.2 Outputs made according to designated output mode when corresponding preset is reached.
Outputs inhibit on the teaching mode.
Batch output
(Standard type)
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.

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.

The batch count output holds until

The present value of the batch count
advances continuously.
1. The batch count present value remains at 0 while the batch
count reset is ON.
2. When the batch count set value is 0, the batch count will
proceed, but there will be no output.
3. When the batch count present value exceeds 9999, it returns
to 0.
4. The batch count present value and output do not affect the
RESET Key or reset input.
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.
7. If, after the output has gone ON, the set value is changed to a
set value which is greater than the present value, the output
will remain 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).

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.
ON
OFF
0 to 50 ms 10 ms 0 to 1.2 s
Power
supply
Input impossible impossible
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 sup-
plied is invalid. Restart the power supply.
Self-diagnostic Function
•The following displays will appear if an error occurs. The present
value and output enter the same status as after pressing the
RESET Key.

**Displayed when the present value has exceeded the max. value in
the H7BR-C (±range type).
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).
H7BR 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.)

1 kHz {cps} 0.72 to 0.94 ms
5 kHz {cps} 0.42 to 0.57 ms
10 kHz {cps} 0.37 to 0.49 ms
*The variation in delays is due to different modes and conditions.
For systems where the delay is a problem, take actual measure-
ments under operating conditions.
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.

time
1 ms 0.8 to 1.2 ms
20 ms 15 to 25 ms
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.
