List of Terms
Check In appropriate measurements by means of the specified test equipment, prop-
er functioning of a unit or module is established.
Discolouration Components such as connectors and printed circuit boards are examined if
they have changed colour due to temperature effects and thus differ widely
from their normal condition.
Disconnect Pull off connector.
Examine In case of trouble the unit / module or components such as e.g. connectors,
are to be thoroughly checked for obvious mechanical damage.
Functional check This means that components / modules / units are checked for proper func-
tioning while installed.
Hazardous voltages Voltages > 30 Vrms or 50 Vpp (AC) or 50 V (DC)
Make sure Ascertain whether all mentioned requirements are met or allmeasures are tak-
en to establish the required condition.
Open Access is to be gained to the unit / module by observing the given instructions
and safety precautions.
Perfect condition This means that a component / module / unit has to be in a state which does
not give cause to complaints.
Replacement In case of trouble the replacement of modules is carried out in order to localize
and eliminate the fault.
Replace Components / modules / units which - due to damage and / or other defects -
no longer meet the respective requirements or components / modules / units
which during troubleshooting were identified as the cause of fault, are to be re-
placed.
Visual examination This is a visual inspection of the outer appearance and completeness of a
component / module / unit without manual interference by the examiner. This
does not include the necessary preparations and finishing work such as open-
ing and closing of covers or similar.
