H7E@[email protected]
H7E@[email protected]
3-V
battery
When designing a circuit, keep the power wiring connections shorter than 50
mm. Refer to the connection diagram above for the proper wiring polarity.
The life expectancy of a battery power supply can be calculated by
the following formula:
t = A/lc
Where,
t: Life expectancy of battery (h)
A: Battery capacity (mAh)
lc: H7E@[email protected] current consumption (mA)
Example:
Battery life when using a 3-V lithium battery with a capacity of
1,200 mAh for the H7E@[email protected]
Backup
circuit
Use a diode (D) having a forward voltage as small as possible (0.1 V
max. at IF of 20 μA).
Determine the ratio of R1 to R2 in accordance with the forward voltage of the diode to be used. Be aware that when the power supplied
to the H7E@[email protected] has dropped to less than the voltage of the
backup circuit, the battery will discharge.
To protect the circuit against a momentary power failure, an aluminum
electrolyte capacitor can be used in place of a battery, as shown below:
H7E@[email protected]
t = 1,200 [mAh]/20 × 10–3 [mA] = 60,000 hours (approx. 6.8 years)
The battery capacity varies depending on the type of battery used;
oxidized silver, mercury, or lithium battery.
Backup
circuit
Voltage Division of Power Supply Circuit
When necessary, the voltage from the battery may be divided by resistances:
When a capacitor is used, its backup time can be calculated by the
following formula:
t = C (V1 – V2) / Ic
H7E@[email protected]
Where,
t: Backup time (s)
C: Capacitance (μF)
V1: Supply voltage before power failure (V)
V2: Minimum operating voltage of H7E@[email protected] (V)
Ic: H7E@[email protected] current consumption (μA)
When doing so, however, ensure that the following equation balances:
E (V) × R2 / (R1 + R2) = 3 V

12 V
24 V
R1
2 kΩ
9.1 kΩ
33 kΩ
R2
3 kΩ

4.7 kΩ
Allow a current high enough to flow through R1 so that the [email protected]@P receives sufficient current.
C is a film capacitor, of about 0.1 μF, and is intended to absorb noise
induced by the power lines.
Keep the wiring between the H7E@[email protected] and R2 or C as short as
possible (within 50 mm).
Example:
Backup time by an aluminum electrolytic capacitor of 100 μF. (Minimum operating voltage of H7E@[email protected] is 2.6 V.)
t = 100 μF × (3–2.6 V)/20 μA = 100 × 0.40/20 = 2.0 seconds
Note that the above calculation provides an approximate value,
which varies depending on the environment under which the Counter
is used and also on the type of capacitors used. Provide some allowance in selecting capacitors.
Keep the wiring between the H7E@[email protected] and R2 or C as short as
possible (within 50 mm).

Precautions (Common)
Refer to Safety Precautions for All Counters.
■ New H7E (Except for PCB-mounting Counter)
!WARNING
!CAUTION
This product has a built-in lithium battery. Do not short-circuit the +
and − terminals, charge, disassemble, deform, or expose the battery
to fire. The battery may explode (break), catch fire, or cause liquid
leakage.
Do not use any battery other than the specified one (Y92S-36). Using
another battery may cause liquid leakage or breakage, resulting in
malfunction or injury.
If a voltage other than the rated one is applied, internal elements may
be damaged.
Do not use the Counter in the following places:
• Locations subject to direct sunlight.
• Locations subject to corrosive gases.
• Locations subject to dust.
Before Use
Reset Input and Count/Timer Input
• An insulation sheet has been inserted to maintain the quality of the
Totalizer in the event of a long period without use. Be sure to
remove this sheet before attempting to use the product.
Remove the insulation sheet and press the Reset Key on the front
panel of the Counter. (With the H7ER-N,-NV(-H),-NV1(-H), models,
“0” or “0.0” will be displayed after 1 s.)
• The H7E operates using its built-in Battery. If the H7E is connected
to a device that has +V and OUT terminals that are connected with
a diode as shown in the circuit diagram, the circuit indicated by the
arrow 1 or 2 will be formed when the device is turned OFF. As a
result, the H7E may be reset or count by one. It is recommended
that such devices not be connected to the H7E.

• Switch settings on the Counter must be performed before mounting
it to a control panel.
• Do not use the Counter in the following locations:
• Locations subject to severe changes in temperature.
• If an excessive voltage is applied to the count/timer input or reset
input terminals, the internal elements may be damaged.
Ensure that the following voltages are not exceeded:
• PNP/NPN universal voltage input model: 30 VDC
• Locations subject to condensation as the result of high humidity.
• AC/DC voltage input model:
At count/timer input: 240 VAC (peak voltage: 338V)

• No-voltage input model: No voltage can be applied.
Mounting Precautions for Flush
Mounting
Although the operating section is watertight (conforming to NEMA4,
IP66), rubber packing is provided to avoid water leakage through the
gap between the Counter and panel cutout. Unless this rubber packing is tightly squeezed on, water may permeate inside the panel.
Therefore, be sure to tighten the screws for fixing the Y92F-34 Flush
Mounting Bracket. (Excessive tightening may also deform the rubber
packing.)
Screw for the Flush Mounting Bracket
The wider side must
face the panel.
• Avoid wiring close to high-tension or large-current lines.
• Do not remove the outer case when voltage is being applied to the
power supply terminals or the input terminals.
• The input for the H7E@-NFV-@ is a high-impedance circuit and so
influence from an induced voltage may result in malfunction. Therefore, when the input signal wiring is longer than 10 m (line capacitance of 120 pF/m, at room temperature), it is recommended that a
CR filter or a bleeder resistor is connected.

When using the Counter in an environment where the Counter is
subject to frequent occurrences of vibration or shock, or when
mounting the Counter facing downwards or sideways, it is suggested
that the Counter be directly soldered to a PCB instead of using sockets.
To Conform to EN/IEC Standards
No-voltage input: 3 VDC
General Information
Finish soldering under the conditions below.
Solder the terminals within 5 seconds, at a solder iron tip temperature of 250°C ± 10°C when using lead solder, and within 3 seconds,
at a solder iron tip temperature of 350°C ± 10°C when using leadfree solder.
Since the Counter is not flux-tight, do not use flux when soldering.
Input terminals have no insulation from power supply terminals. The
power supply terminals must be supplied from a SELV source in
accordance with IEC61010-1 Annex H. SELV (separated extra-low
voltage) source is a power supply having double or reinforced insulation between the primary and the secondary circuit and having output voltage of 30 V rms max. and 42.4 V peak max. or 60 VDC max.
Cleaning
Avoid automatic and dip soldering. Manually solder the Counter onto
a PC board, and avoid cleaning as much as possible.
To prevent damage, the exterior of the Counter must not be exposed
to organic solvents (3.g. paint thinner or benzine), strong alkalis, or
strong acids.
When mounting the Counter on a PC board with components which
consume higher current than the H7E@[email protected], observe the following
precautions.
Others
1. Minimize the wiring (less than 50 mm) from the H7E@[email protected] to the
power supply section.
2. Avoid placing the H7E@[email protected] power, timer, counter, or reset input
circuit in parallel with circuits that consume large currents, particularly on the positive side.
