Installation
Cross-linking via the
connection RS485
Î
The connections must be made in accordance with the specification of the inter-
face RS485.
Î
Connect all units with D+ (pin 5 / RS485) and D- (pin 7 / RS485) to the bus.
• The group address of the TC 600 is 960.
• All units connected to the bus must have differing serial interface addresses (pa-
rameter 797).
• All switched on remote functions have priority over the serial interface func-
tions.
• Refer to the component operating instructions for detailed information concer-
ning operation procedures and electrical data of the interface RS485.
5.6 Connecting the remote control
Remote control options are provided via the 15-pole D-Sub connector with the des-
ignation ”REMOTE“ on the TC 600. The inputs 2 - 6 are activated by connecting
them with +24 V at Pin 1 (active high)
(see p. 19, chap. 5.7)
. When connecting sup-
ply voltage the turbopump is started.
•
On delivery: Pin 1, Pin 2, Pin 3 and Pin 4 are bridged in the remote plug.
Î
Shielded cable must be used.
Î
Connect the shielding on the plug side for the TC 600 to the TC housing.

CAUTION
Danger of electric shock
The insulation measures of the bus system are designed only for use with safety extra-
low voltage.
Î
Connect only suitable devices to the bus system.
NOTE
Connection to an external bus system
The integration into an external bus system (e.g. Profibus DP, DeviceNet) is possible
via connection gateway TIC 250 or TIC 260. Thus a synchronous use of interface
RS485 on the TC 600 is not possible.
