2. When the elapsed (measured) time
reaches full scale it returns to “0”, and
then measuring starts again from “0”.
3. When reset input is ON, the display
becomes “0”. You cannot measure during
reset input.
For PC board mounting type the display
disappears while the reset input is ON;
however, the display reads “0” when the
reset input turns OFF.

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
V.
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)

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 k.
(When the impedance is 0 , 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 k.
(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.
