WARNING!
Laser injection!
Do not look directly into the fiber-optic elements!
Signals transmitted via optical fibers are unaffected by interference. The fibers guar-
antee electrical isolation between the connections. Transmit and receive connections
are represented by symbols.
The character idle state for the optical fiber interface is „Light off". If the character idle
state is to be changed, use the operating program DIGSI, as described in the SIPRO-
TEC 4 System Description.
If one or two 7XV566 temperature meters are connected, check their connections to
the port (port C or D).
Verify also the termination: The terminating resistors must be connected to
7SJ62/63/64 (see margin heading „Termination").
For further information refer to the operating manual of 7XV566. Check the transmis-
sion settings at the temperature meter. Besides the baudrate and the parity observe
also the bus number.
For connection of RTD-box(es) proceed as follows:
• For connection of 1 RTD-box 7XV566: bus number = 0 (to be set at 7XV566).
• For connection of 2 RTD-boxes 7XV566: bus number = 1 for the 1st RTD-box (to
be set at 7XV566 for RTD 1 to 6), bus number = 2 for the 2nd RTD-box (to be set
at 7XV566 for RTD 7 to 12).
Please observe that detector input 1 (RTD1) of the first RTD-box is assigned for
ambient or coolant temperature of the overload protection.
