Installation
5.5 Connecting Pfeiffer Vacuum display and control units or PC
Fig. 8: Connecting the serial interface RS485
An external operating part (DCU
or
HPU 001)
or
an external computer can be con-
nected via the connection with the designation "RS485" on the electronic drive
unit. The interface is securely separated galvanically from the maximum occurring
supply voltage of the TC 600. The electrical couplings are optically decoupled in-
ternally.
Connections
The connection of a RS232- oder USB-interface is possible via a TIC 001 or the
USB/RS485-converter.
NOTE
Observe the connection instructions!
On delivery turbopumps with TC 600 are set up for operations with "Remote Control".
Î
Before operating with DCU, HPU or PC the 15-pole D-Sub connector (remote plug)
must be removed from the TC 600.
