CESVA ENOS LRF-05 Manuel D'instructions page 30

 Parameter zone: This zone provides access to the parameter values according to which
the limiter has been programmed. These values can be edited. The LRF-05 is
programmed with these values.
The parameters to programme the LRF-05 are the following:
 Clock: This indicates the date and time of the computer and allows you to select the
automatic winter/summer time change. When the limiter is programmed, it remains
programmed with this date and time.
 Sessions schedule: Use this parameter to introduce the opening hours of the
establishment for each day of the week. The schedule must fulfil the following
prerequisites:
 The beginning of the interval must coincide with the day of the week being
programmed.
 The interval must be less than 24 h.
 The end of the interval may belong to the day after programming.
 The schedules corresponding to consecutive days must not overlap.
NOTE: It is important to remember that the LRF-05 attenuates at 60 dB outside the session
schedules. If you don't want this to happen, each day must be programmed with 24-hour
sessions.
To introduce the schedules, double click on any day. A menu will appear for the introduction
of the different schedules. For each day, you can choose between entering a (beginning –
end) schedule, to allow the music equipment to function all day, or the (closed) schedule on
days when it does not function.
 Regulations: Use this option to introduce information relating to the regulations
governing the establishment: schedule for nocturnal and diurnal evaluation and
maximum levels for each time zone and for the different points of evaluation (emission
and reception). By emission we understand the point where the sensor measures the
sound pressure level, and by reception the point in the adjacent dwelling for which the
sound pressure level is calculated through the insulation introduced into the
programming.
NOTE: All this information may be found in the regulations governing each kind of
establishment.
 Control mode: The LRF-05 acts according to the sound level measured in the emitting
establishment. The control algorithm the LRF-05 uses is based on the equivalent sound
level acoustic parameter (Leq). When programming the control mode, the control time
must be chosen, which corresponds to the integration time used in the calculation of the
Leq parameter (from 125 ms to 10 s).
If a long (10 s) control time is chosen, the control algorithm will ensure a progressive
variation in the control of the music, without excessively sudden changes in its level and
without its being affected by brusque variations in the music. On the other hand, if we
choose a short (125 ms) control time, the LRF-05 will act much faster, although more
appreciable variations in the music level will be produced. The LRF-05 may also act
according to the calculated sound level in the receiving establishment (dwelling next
door). This option allows you to activate the control mode in the receiving establishment
by means of the previous predictive algorithm (level equivalent to 125 ms at 10 s), or
else to deactivate the mode. If a joint emission and reception control mode is chosen,
the LRF-05 will apply the more restrictive condition of the two at each moment.
We recommend that long control times be used for normal situations and short control
times in establishments with low sound insulation or when stipulated by the regulations.
