Normen Anforderungen
IEC 61496-1: A.7 Muting
2004
A.7.1.2 There shall be at least two independent hard-wired muting signal sources to
initiate the function. It shall not be possible to initiate muting when the OSSDs are
already in the OFF-state.
A.7.1.3 The mute function shall only be inititated by the correct sequence and/or
timing of the mute signals. Should conflicting muting signals occur, the ESPE shall
not allow a muted condition to occur.
A.7.1.4 There shall be at least two independent hard-wired muting signal sources to
stop the function. The muting function shall stop when the first of these muting sig-
nals changes state. The deactivation of the muting function shall not rely only on the
clearance of the ESPE.
A.7.1.5 The muting signals should be continuously present during muting. When the
signals are not continuously present, an incorrect sequence and/or the expiration of
a pre-set time limit shall cause either a lock-out condition or a restart interlock.
A.7.4 Indication: A mute status signal or indicator shall be provided (in some appli-
cations, an indication signal of muting is necessary)
