The signals are low active and are fed to the LED drive via an integrated inverter module with a +5 V supply
voltage.
S6 Control Wires
The CLE module contains an optocoupler for the S6 control wire. The S6 control wire is used for disconnecting
voice and data signals in a Siemens PLC equipment in alternate multi-purpose mode.

Block Diagram of the S6 Control
The circuit is driven on a low-active basis. The optocoupler is activated during transmission of protection data
(S6 control wire = low).
Test Sockets
The following test sockets are provided on the front panel of the CLE module:
•
1 ISEP socket for measuring the level of the receive signal
•
1 ISEP socket for measuring the level of the transmit signal
The level at the sockets is measured on a high impedance basis and corresponds to the value at the measuring
point. Incorrect operations such as short circuiting or inserting a signal (U ≤ 5 V) at the measuring sockets does
not result in interruption of teleprotection signaling.
