olack of signal MAIN or lowering of the level of the same below the threshold
THR reference for a time over one established.
odetection of a level of the 19 KHz pilot signal which differs by a value greater
than or less than ± 1 dB than the set value
oabsence of RDS signal or inconsistent data of the it
odetection of a PI code in the RDS signal, different from that set.
oRestoring the MAIN signal input or its level above the threshold THR, or one of the
checks listed above, for the minimum time edited, the output will switch on the input
MAIN. in this mode is the primary external command applied via contact ST IN port
Logic I/O through which one can impose the switching input SUB regardless of the
level of the signal MAIN.
oSTUDI: The input signal at the output is determined by the state of the contact ST
IN port Logic I/O, open contact = MAIN, SUB = closed contact. The control of the
signal level, in this case, is applied to the SUB, in case of no signal or less than the
predetermined threshold THR, the end of the observation time imposed, the output is
switched to the MAIN regardless of the state contact ST IN.
oMAI ; manual setting and fixed input MAIN output, control the level of the signal
shows the status of the alarm contact output port Logic I/O but does not cause
switching. The switch from MAIN to SUB can not be activated by contact of dedicated
Logic I/O port.
oSUB; manual setting and fixed input SUB output, control the level of the signal
shows the status of the alarm contact output port Logic I/O but does not cause
switching. Switching from SUB MAIN can not be activated by contact of dedicated
Logic I/O port.
STE DELAY to SUB; pressing the og wheel, at this entry, to access setting of the observation
time signal MAIN, beyond which, in SUPERVISOR mode (SUPER), with allame active, the output is
switched on the SUB. The available range is from 0 to 255 seconds
STE DELAY to MAI ; pressing the og wheel, at this entry, to access setting of the observation
time of the signal level SUB, beyond which, in STUDIES mode, the output is switched on MAIN. The
available range is from 0 to 255 seconds.
STE BLA K THR; pressing the og wheel, at this entry, to access setting the threshold level of
Stereo. The available range varies from -18 to -4 dB; OFF control is disabled.
MPX DELAY to SUB; pressing the og wheel, at this entry, to access setting of the observation
time signal MAIN, beyond which, in SUPERVISOR mode (SUPER), compared with alarm, the output
is switched on the SUB. The available range is from 0 to 255 seconds
MPX DELAY to MAI ; pressing the og wheel, at this entry, to access setting of the observation
time of the signal level SUB, beyond which, in STUDIES mode, the output is switched on MAIN. The
available range is from 0 to 255 seconds.
MPX BLA K THR; pressing the og dial, at this entry, to access setting the threshold level of the
stereo signal; . The available range varies from -18 to -4 dB; OFF control is disabled.
MPX PILOT LEV; pressing the og wheel, at this entry, to access setting the threshold level of the
pilot signal 19 KHz. The available range varies from -26 to -14 dB; OFF control is disabled.
.
MPX RDS ALARM; pressing the og wheel, at this item, you can then select the type of control
activated the RDS signal :
oRDS S, Control of the RDS signal, data consistency in the RDS signal
oPI CHK, Control of the PI code contained in the RDS signal
oOFF, Disabling the control signal RDS
