English 7XV5654-0BA00
As optical input signal at the input R2 a minutes pulse from the GPS-receiver 7XV5664-
0AA00 for SIPROTEC 3 devices is received. The pulse is optic-electrically converted
and given out as a 24 V electrical signal to X1 at PIN 4/8. A semiconductor output
switches the pulse. The telegram at R1 is converted to an electrical signal at X1 at PIN
1/3. For the distribution into two divided buses, the T-adapter cable 7XV5104-3AA00 is
required. For the wiring from T-adapter to the binary inputs of the SIPROTEC 3 devices
no prefabricated cables are supported. The cables should have two twisted wires and
should be shielded. The length of the cables should not exceed 10 m. Max. 10
SIPROTEC 3 devices with there binary inputs can be connected to one electrical output
at X1. Light idle state ´ON´ at the input R2 lead to a 24 V voltage at the semiconductor
output. The pulse is shown with LED ´RCV2´ at the front plate.
Please note, that the trigger level of the binary inputs in the SIPROTEC 3 devices must
be set below 24 V. That can be done by jumpers in the device (described in the manual
of the SIPROTEC 3 device).
Synchronizing of maximum 20 SIPROTEC 3 devices
Should maximum 20 SIPROTEC 3 devices be synchronized with a minute pulse via
there binary inputs, each 10 devices must be connected to the two electrical outputs of
X1. The optical minute pulse is programmed for output A of the GPS-receiver. It's
received via a fibre optic cable at input R1 at the Sync.-Transceiver.
The optical time synchronization pulse is received for that application only at R1. This
signal is optic-electrically converted and given parallel to both electrical outputs, when at
DIP-switch S1 switch 3 is at position ´ON´ (´OFF´ is the factory setting ).
For distributing the electrical pulse to the binary inputs of the SIPROTEC 3 devices
please refer to the description of the last application.
