Cautions for use

1. Non-voltage input type

For both panel mounting and PC

board mounting types

1) Never apply voltage to the non-voltage

input type. This will damage the internal

elements.

2) Since the current flow is very small

from the start input and reset input

terminals (1 and 3 on the panel

mounting type and terminals e to t and

S to F on the PC board mounting type)

please use relays and switches with high

contact reliability. When inputting with an

open collector of a transistor, use a

transistor for small signals in which ICBO

is 1 µA or less and always input with no

voltage.

3) When wiring, try to keep all the input

lines to the start and reset inputs as short

as possible and avoid running them

together with high voltage and power

transmission lines or in a power conduit.

Also, malfunctions might occur if the

floating capacitance of these wires

exceeds 500 pF (10 m 32.808 ft. for

parallel wires of 2 mm2). In particular,

when using shielded wiring, be careful of

the capacitance between wires.

PC board mounting type

1) For external power supply use

manganese dioxide or lithium batteries

(CR type: 3V).

2) Always reset after external power is

applied and confirm that the display

reads “0”.

3) Make the wiring from the battery to the

hour meter unit as short as absolutely

possible. Also, be careful of polarity.

4) Calculate battery life with the following

formula.

t = A/I

t: battery life [h]

I: LH2H current consumption [mA]

A: battery capacity until minimum

operation voltage is reached [mAh]

5) Hand solder to the lead terminal. Do

not dip solder. With the tip of the

soldering iron at 300°C 572°F perform

soldering within 3 seconds (for 30 to 60

W soldering iron).

2. Voltage input type

1) Be aware that applying more than 30 V

DC to start input terminals 1 and 2, and

reset input terminals 3 and 4 will cause

damage to the internal elements.

2) For external resetting use H level

(application of 4.5 to 30 V DC) between

reset terminals 3 and 4 of the rear

terminals. In this case, connect + to

terminal 3 and – to terminal 4. This is

the valid polarity; therefore, the hour

meter will not work if reversed.

3) When wiring, try to keep all the input

lines to the start and reset inputs as short

as possible and avoid running them

together with high voltage and power

transmission lines or in a power conduit.

Also, malfunctions might occur if the

floating capacitance of these wires

exceeds 500 pF (10 m 32.808 ft. for

parallel wires of 2 mm2).

3. Free voltage input type

1) Use start input terminals 1 and 2 for

free voltage input and reset terminals 3

and 4 for non-voltage input.

2) Be aware that the application of

voltage that exceeds the voltage range of

the H level to the start input terminal, and

the application of voltage to the reset

input terminal, can cause damage to the

internal elements.

3) Since the current flow is very small

from reset input terminal 3, please use

relays and switches with high contact

reliability.

4) When inputting a reset with an open

collector of a transistor, use a transistor

for small signals in which ICBO is 1 µA or

less and always input with no voltage.

5) To reset externally, short reset input

terminals 3 and 4 on the rear.

6) Input uses a high impedance circuit;

therefore, erroneous operation may occur

if the influence of induction voltage is

present. If you plan to use wiring for the

input signal that is 10 m or longer (wire

capacitance 120 pF/m at normal

temperature), we recommend the use of

a CR filter or the connection of a bleeder

resistor.

4. How to reset multiple panel

mounting type counters all at once

(input is the same for count)

Non-voltage input type

Notes) 1. Use the following as a guide for choosing

transistors used for input (Tr).

Leakage current < 1 µA

2. Use as small a diode (D) as possible in the

forward voltage so that the voltage between

terminals 3 and 4 during reset input meets

the standard value (0.5 V).

( At IF = 20 µA, forward voltage 0.1 and

higher.)

Voltage input type

Note) Make sure that H (reset ON) level is at least 4.5

5. Backlight luminance

To prevent varying luminance among

backlights when using multiple Backlight

types, please use the same backlight

power supply.

6. Acquisition of CE marking

Please abide by the conditions below

when using in applications that comply

with EN 61010-1/IEC 61010-1

1) Ambient conditions

• Overvoltage category II, pollution level 2

• Indoor use

• Acceptable temperature and humidity

range: –10 to +55°C, 35 to 85%RH (with

no condensation at 20°C)

• Under 2000 m elevation

2) Use the main unit in a location that

matches the following conditions.

• There is minimal dust and no corrosive

gas.

• There is no combustible or explosive

gas.

• There is no mechanical vibration or

impacts.

• There is no exposure to direct sunlight.

• Located away from large-volume

electromagnetic switches and power

lines with large electrical currents.

3) Connect a breaker that conforms to

EN60947-1 or EN60947-3 to the voltage

input section.

4) Applied voltage should be protected

with an overcurrent protection device

(example: T 1A, 250 V AC time lag fuse)

that conforms to the EN/IEC standards.

(Free voltage input type)

7. Terminal connection

Tighten the terminal screws with a torque

of 0.8 N·cm or less.

1. It is possible to change the set time

even during time delay with the timer.

However, be aware of the following

points.

1) If the set time is changed to less than

the elapsed time (elapsed value) with the

time delay set to the addition direction,

time delay will continue until the elapsed

time reaches full scale, returns to “0

(zero)”, and then reaches the new set

time.

If the set time is changed to a time above

the elapsed time, the time delay will

continue until the elapsed time reaches

the new set time.

2) If the time delay is set to the

subtraction direction, time delay will

continue until “0 (zero)” regardless of the

new set time.

2. If the set time is changed to “0 (zero)”,

the hour meter will operate differently

depending on the operation mode.

In the G (Totalizing ON delay), B (Signal

ON delay), and E (Pulse ON delay)

modes, the output turns ON when the

start input is ON. However, the output will

be OFF while reset is being input.

In the F (Signal flicker) mode, the flicker

operation will not work even if start input

is turned ON.

Cautions for use

Compliance with the CE marking

1. Input and output connection

1) Input connection

(1) Contact input

Use highly reliable metal plated contacts.

Since the contact’s bounce time leads

directly to error in the timer operating

time, use contacts with as short a bounce

time as possible.

(2) Non-contact input (Transistor input)

Connect with an open collector. Use

transistors whose characteristics satisfy

the criteria given below.

VCEO = Min. 20 V

IC = Min. 20 mA

ICBO = Max. 6 µA

Also, use transistors with a residual

voltage of less than 2 V when the

transistor is on.

* The short-circuit impedance should be less

than 1 kΩ.

(When the impedance is 0 Ω, the current

coming from the start input terminal is

approximately 5 mA and from the reset

input terminal is approximately 1.5 mA.)

Also, the open-circuit impedance should

be more than 100 kΩ.

(3) Input wiring

When wiring, use shielded wires or

metallic wire tubes, and keep the wire

lengths as short as possible.

2) Output connection

Since the transistor output of hour meter

is insulated from the internal circuitry by a

photo-coupler, it can be used as an NPN

output or PNP (equal value) output.

2. Self-diagnosis function

If a malfunction occurs, one of the following displays will appear.

* Includes the possibility that the EEP-ROM’s life has expired.

3. Power failure memory

The EEP-ROM is overwriting with the following timing.

4. Terminal connection

1) When wiring the terminals, refer to the terminal layout and

wiring diagrams and be sure to perform the wiring properly

without errors.

Tighten the terminal screws with a torque of 0.8 N·cm or less.

The screws are M3.5.

An external power supply is required in order to run the main

unit.

Power should be applied between

terminals (1) and (2). Terminal (1) acts

as the positive connection and terminal

(2) as the negative.

2) After turning the hour meter off, make sure that any resulting

induced voltage or residual voltage is not applied to power

supply terminals (1) through (2). (If the power supply wire is

wired parallel to the high voltage wire or power wire, an induced

voltage may be generated at the power supply terminal.)

3) Have the power supply voltage pass through a switch or relay

so that it is applied at one time.

FOREIGN SPECIFICATIONS OVERVIEW

4. Shipping Standards

(1) Lloyd’s Register of Shipping

Standards from the Lloyd’s Register shipping asso-

ciation based in England. These standards are

safety standards for environmental testing of the

temperature and vibration tolerances of electrical

components used for UMS (unmanned machine

rooms in marine vessels) applications. These stan-

dards have become international standards for

control equipment in all marine vessel applications.

No particular action is taken to display the confor-

mation to these standards on the products.

1. International Standards

IEC standard

International Electrotechnical Commission

By promoting international cooperation toward all

problems and related issues regarding

standardization in the electrical and electronic

technology fields, the IEC, a non-governmental

organization, was started in October, 1908, for the

purpose of realizing mutual understanding on an

international level. To this end, the IEC standard

was enacted for the purpose of promoting

international standardization.

2. North America

UL (Underwiters Laboratories Inc.)

This is a non-profit testing organization formed in

1894 by a coalition of U.S. fire insurance firms,

which tests and approves industrial products

(finished products). When electrical products are

marketed in the U.S., UL approval is mandated in

many states, by state law and city ordinances. In

order to obtain UL approval, the principal parts

contained in industrial products must also be UL-

approved parts.

UL approval is divided into two general types. One

is called “listing” (Fig. 1), and applies to industrial

products (finished products). Under this type of

approval, products must be approved

unconditionally. The other type is called

“recognition” (Fig. 2), and is a conditional approval

which applies to parts and materials.

CSA (Canadian Standards Association)

This was established in 1919 as a non-profit, non-

governmental organization aimed at promoting

standards. It sets standards for industrial products,

parts, and materials, and has the authority to judge

electrical products to determine whether they

conform to those standards. The CSA is the ultimate

authority in the eyes of both the government and the

people in terms of credibility and respect. Almost all

states and provinces in Canada require CSA

approval by law, in order to sell electrical products.

As a result, electrical products exported from Japan

to Canada are not approved under Canadian laws

unless they have received CSA approval and

display the CSA mark. Approval is called

“certification”, and products and parts which have

been approved are called “certified equipment”, and

display the mark shown in Fig. 3. The mark shown

in Fig. 4 is called the “Component Acceptance”

mark, and indicates conditional approval which is

applicable to parts. The C-UL mark shown in Fig. 5

(finished products) and Fig. 6 (parts) indicates that

the product has been tested and approved in UL

laboratories, based on UL and CSA standards,

through mutual approval activities.

3. Europe

EN standard

European Standards/Norme Europeennee

(France)/Europaishe Norm (Germany)

Abbreviation for European Standards. A unified

standard enacted by CEN/CENELEC (European

Standards Committee/European Electrical

Standards Committee). EU and EFTA member

nations employ the content of the EN standards into

their own national standards and are obligated to

abolish those national standards that do not agree

with the EN standards.

(1) Germany

VDE (Verband Deutscher Elektrotechniker)

The VDE laboratory was established mainly by the

German Electric Technology Alliance, which was

formed in 1893. It carries out safety experiments

and passes approval for electrical devices and

parts. Although VDE certification is not enforced

under German law, punishment is severe should

electrical shock or fire occur; therefore, it is, in fact,

like an enforcement.

TÜV (Technischer Überwachungs-Verein)

TÜV is a civilian, non-profit, independent

organization that has its roots in the German Boiler

Surveillance Association, which was started in 1875

for the purpose of preventing boiler accidents. A

major characteristic of TÜV is that it exists as a

combination of 14 independent organizations (TÜV

Rheinland, TÜV Bayern, etc.) throughout Germany.

TÜV carries out inspection on a wide variety of

industrial devices and equipment, and has been

entrusted to handle electrical products, as well, by

the government. TÜV inspection and certification is

based mainly on the VDE standard.

TÜV certification can be obtained from any of the 14

TÜVs throughout Germany and has the same

effectiveness as obtaining VDE certification.

CE MARKINGS OVERVIEW

Counter, Hour Meter conforming to

EN/IEC standards

The Timer, Counter, Hour Meter shown below conform to both EN and IEC standards,

and may display the CE markings.

CE markings and EC

directives

The world’s largest single market, the

European Community (EC) was born on

1 January 1993 (changing its name to

EU in November 1993. It is now always

expressed as EU, apart from EC direc-

tives.) EU member country products

have always had their quality and safety

guaranteed according to the individual

standards of each member country.

However, the standards of each country

being different prevented the free flow of

goods within the EU. For this reason, in

order to eliminate non-tariff barriers due

to these standards, and to maximize the

merits of EU unification, the EC direc-

tives were issued concomitant to the

birth of the EU.

The EN standards were established as

universal EU standards in order to facili-

tate EU directives. These standards

were merged with the international IEC

standards and henceforth reflect the

standards in all countries. Also, the CE

markings show that products conform to

EC directives, and guarantee the free

flow of products within the EC.

Appropriate

EC directives for control

equipment products

The main EC directives that are to do

with machinery and electrical equipment

are the machinery directive, the EMC

directive, the low voltage directive, and

the telecom directive. Although these

directives have already been issued, the

date of their enactment is different for

each one. The machinery directive was 1

January 1995. The EMC directive was 1

January 1996, and the low voltage direc-

tive was enacted from 1 January 1997.

The telecom directive was established by

the separate CTR (Common Technology

References.)

What are EN standards?

An abbreviation of Norme Europeenne

(in French), and called European

Standards in English. Approval is by vote

among the CEN/CENELEC member

countries, and is a unified standards

limited to EU member countries, but the

contents conform to the international

ISO/IEC standards.
