Precautions

New H7E (Except for PCB-mounting Counter)

WARNING

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,

cause liquid leakage.

Caution

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

Caution

If a voltage other than the rated one is applied, internal ele-

ments

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

•An

insulation sheet has been inserted to maintain the quality of

the

otalizer 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.)

•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.

SLocations

the result of high humid

ity.

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 Flush

Mounting

Bracket. (Excessive tightening

may also deform the rub

ber

packing.)

Reset Input and Count/Timer Input

•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

may be reset or count

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

is a high-impedance circuit and

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.

No-voltage input: 3 VDC

General Information

The

terminals are solder-plated. Finish soldering the terminals with

5 seconds, at a solder iron tip temperature of 250

°C

°.

Since

the Counter is not flux-tight, do not use flux when soldering.

Avoid automatic and dip soldering. Manually solder the Counter

onto

a PC board, and avoid cleaning as much as possible.

When

mounting the Counter on a PC board with components which

consume

higher current than the H7E

j-NjP

, observe the

ing precautions.

1. Minimize

the wiring

(less than 50 mm) from the H7E

2. Avoid

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 sug-

gested

that the Counter be directly soldered to

a PCB instead of us

ing sockets.

To Conform to EN/IEC Standards

Input

terminals have no insulation from power supply terminals. The

power

supply terminals must be supplied from a SEL

source in ac

cordance with IEC61010-1 Annex H. SELV (separated extra-low

voltage) source is a power supply having double or reinforced in-

sulation

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
