7-5 Timing constants (muting function) 21
7-5 Timing constants (muting function)
a) The muting request must take place with the correct timing sequence: the Muting A input must be en-
abled first and then the Muting B input. The request for the latter must be made within a maximum of 3
seconds and not before 30 ms (Tm) after enabling Muting A input. Otherwise the muting function will not
be enabled. An incorrect sequence on the muting inputs will not start the muting process.
b) Muting status can be maintained for an unlimited period of time as long as the muting signals are valid.
A muting request cannot be made if the SLC outputs are open, that is to say when the beams have
been interrupted.
7-6 Timing constraints
(for SLCs with postfix "-MTL" at the ordering code)
a) The muting request must take place with the correct timing sequence: the Muting A input must be en-
abled first and then the Muting B input. The request for the latter must be made within a maximum of 3
seconds and not before 30 ms after the enabling of the Muting A input. Otherwise the muting function
will not be enabled. An incorrect sequence on the muting inputs will not start the muting process.
b) There are 5 seconds maximum from the activation of muting to the package entrance in the protected
area by interrupting the SLC. If this time is exceeded, muting function will stop immediately.
c) As long as a package interrupts the protected area (at least one beam), the muting function is maintained
d) Muting status can be maintained for an unlimited period of time as long as the muting signals are valid.
