4.3.8
Tripping Indicator (optional)
The encoder Output X4 shows the state of the safe-
ty switch X7 and the state of the tripping coils. The
Signal load has to be connected between X4/1 and
supply voltage as well as X4/3 and supply voltage
(see 4.1.3).
Supply voltage has to be below 32VDC and 100mA
for each channel. If the Safetycircuit is close, X4/1
and X4/3 are active (switched on). If the Safety
Circuit of the EOS gets opened (e.g. by reaching
contact speed CS) , channel X4/1 will switch off. If
the Tripping coils get activated (e.g. by reaching
tripping speed TS), cahnnel X4/3 of the encoder out-
put gets switched off. When the encoder option is
ordered the error indicator (4.3.9) is disabled.
4.3.9
Error indicator (standard)
The encoder Output X4 shows errors and warnings.
The Signal load has to be connected between X4/1
and supply voltage as well as X4/3 and supply volt-
age (see 4.1.3).Supply voltage has to be below
32VDC and 100mA for each channel.
An Errorsignal is shown on both channels X4/1 and
X4/3 of the encoder output, for error indication see
capture 4.6.5. Errors and Warnings are shown on
both channels, only in case of mechanical tripping
and EOS not reseted (Synchro blade not in horizon-
tal position, see capture 4.2.5) one of the channels
is off, deppending on the tripping direction.
