Mechanical Life Expectancy
A life expectancy of a timer when the control output of the timer is
operated under no load condition.
OFF-delay Timer
An output signal is generated upon application of a voltage to the
operating circuit. The output signal is removed after the lapse of a
givenpresettimefromtheinterruptionofthevoltagebeingsupplied
to theoperating circuit. The timer remains in the OFFstate until the
re-application of the voltage to the operating circuit.
This timer is also available in two types; one with a power supply
also serving as an operating circuit, and the other with separate
power supply and operating circuit. With the former type, restric-
tions are placed on the available types, operate time, etc.

Since the repeat accuracy is expressed in terms of a percentage
against the maximum setting time, the absolute value of therepeat
accuracy does not change even if the setting time is changed.
Accordingly, the time specification should be taken into account as

CENELECisthe“EuropeanCommitteeforElectrotechnicalStandardization”jointlyfoundedin1973
by the EEC (European Economic Community) and EFTA (European Free Trade Association). It is
headquartered in Brussels, Belgium and currently has 18 member nations.
FacedwithEuropeanmarketunificationin1992,CENELECtookontheveryimportanttaskofcreat-
ing unified European standards and is energetically proceeding with the creation of standards.
The CENELEC standards can be broadly divided into two groups: EN (European Norm) and HD
(Harmonized Document).
ECmembernationsmustusetheENstandardsfornationalstandardswithoutanychanges,butthey
can use national standards that are have the same general content as the HD standards, so some
differences in content are allowed with the HD standards.
TheVDE(Germanelectricaltechnician’sassociation),establishedin1893,ismainlyresponsiblefor
carrying out safety testing and approval administration of electrical products.
CompliancewithVDEstandardsisnotproscribedunderGermanlaw,however,theextremelyheavy
penaltiesimposedonthemanufacturerofanunapprovedproductwhichcausesanelectric-shockor

TheTÜVorganizationsareprivate,non-profitorganizationswhoseparentorganization,theGerman
Boilermaker’s Federation, was founded in 1875 to prevent boiler accidents. There are 14 indepen-
dent TÜV organizations within Germany (such as TÜV Rheinland, TÜV Bayern, etc.).
TheTÜVorganizationsinspectabroadrangeof industrialmachineryandequipment,butis alsoen-
trusted bythegovernment toinspect andapprove electricalproducts basedonthe VDEstandards.
TÜV approval is equally valid as VDE approval, and TÜV approval by any of the 14 independent
organizations is valid with the others.
There are two types of approval marks, the mark on the upper-left is applied to equipment and the
mark on the lower-left is applied to parts within the equipment.
This non-profit organization was established in 1960 and tests mainly household electrical ap-
pliances based on BS standards.
There are two types of BEAB approval marks, the mark on the left is applied to equipment and the
mark on the right is applied to parts within the equipment. Application of the parts approval mark is
optional.
Both UL and CSA require normal TV rating approval for switches and relays used for power supply
switching inappliances such as televisions and radios. ULaccepts tungsten ratings (25,000 switch
operations) for relays.
TheTVratingstestisperformedusinganormaltungstenloadon6samples.Thetungstenlampload
has a inrush current about 10 times the normal current and the switching test is performed 25,000
times on each sample.
The TV ratings display indicates the tested amperage. For example, a switch passing the test for a
normal current of 2 A (at 120 VAC) would be indicated by “TV--2”.

Directive 89/336/EEC Concerning Electromag-
netic Compatibility
The EMC Directive is anew-approach directive laying downequip-
ment protection requirements and leaving it to standards, primarily
harmonized standards or, failing that, national standards, to define
product characteristics.
The EMC Directive is a total harmonization directive, i.e., its provi-
sions replace the national provisions concerned.
TheEMCDirectivemustbetransposedintonational lawby1stJuly
1991. Its provisions have applied since 1st January 1992.
ThewidescopeoftheEMCDirectivehasdemonstratedtheoverrid-
ing need to provide for a transitional period, so as to ensure a har-
moniouschangeoverfromtheapplicationofsystemsofapurelyna-
tional character to an exclusive Community system.
That is why, on 28 April 1992, the Council adopted Directive
92/31/EEC with a view to allowing a transitional period until 31 De-
cember 1995.
During this transitional period, a manufacturer will have the choice
of placing on the market/putting into service:
#Products manufactured in accordance with the EMC Directive,
whereby the free movement of the product is guaranteed
pursuant to the Directive, or
#Products manufactured in accordance with national regulations
or possibly with technical specifications of a non-mandatory
nature, whereby free movement of the product will be
guaranteed pursuant to Article 30 of the EEC Treaty, albeit
subject tothepossiblederogationsprovidedforinArticle36and
