BIT In the BIT (built>in test) it is checked whether all modules of
the basic unit are installed and operative. If required, error
messa es are output which may also inform on the operatin
status of the installed options. In addition, the Tx and Rx paths
are checked. The BIT is initiated either throu h switch>on or on
purpose durin operation by pressin softkey BIT in the MAIN
menu.
Check In appropriate measurements by means of the specified test
equipment proper functionin of a unit or module is estab>
lished.
CM In CM (continuous monitorin ) all important equipment func>
tions are permanently monitored. This check is automatic. Er>
ror messa es are output followin which the operator can ini>
tiate the BIT to localize the fault.
Disconnect Pull off connector.
Examine In case of trouble the unit / module or components such as e. .
connectors, are to be thorou hly checked for obvious me>
chanical dama e.
Functional check This means that components / modules / units are checked for
proper functionin while installed.
Hazardous volta es Volta es > 30 V
rms
or 50 V
pp
(AC) or 50 V (DC)
Make sure Ascertain whether all mentioned requirements are met or all
measures are taken to establish the required condition.
Open Access is to be ained to the unit / module by observin the
iven instructions and safety precautions.
Perfect condition This means that a component / module / unit has to be in a
state which does not ive 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 dama e and / or
other defects > no lon er meet the respective requirements or
components / modules / units which durin troubleshootin
were identified as the cause of fault, are to be replaced.
Simple measurements In addition to the BIT, the operatin condition of the overall
equipment can be checked directly by measurin the transmit
and receive functions. If the iven nominal values are not
reached, the entire transceiver must be sent for repair.
