Important: use double-pole
switches only if all controllers are
supplied by the same transformer
Electrical Cabinet
Important: Never connect
the secondary coil of the
transformer to PE!
Danger of destruction!
Attention
Networking of TAR controllers
All controllers can be networked to a host (PC or
SMZ) via their built-in RS-485-interface.
• Because all units are connected parallel on the
data cable, each unit has its own network address
(
P39
) to ensure a specific communication.
!! Never use address 64 !!
• The data transmission speed is fixed by
P38
, the
default value is 9600 Baud.
• Wiring must be made by standard data cable.
• Shieldings must be connected to the nearest
grounding terminal.
• The unshielded part of the data cable must be as
short as possible.
If networked controllers
(1700-2
types only) are sup-
plied by one transformer only and the single positions
must be switched off, use double-pole switches
only. If not, the unit will be supplied partially over
the shielding of the data connection and continues
operation, depending on the secondary voltage of
the transformer. Please note: If a unit is not supplied,
the PC-software notifies a unit breakdown !
A better way is not to switch-off the supply voltage
but to disable the unit by Digital Input.
