Connection "
remote
"
Remote control is possible via the 26-pin D-sub connector labelled "
remote
" on the elec-
tronic drive unit. The accessible individual functions are mapped to "PLC levels".
Remove the remote plug from the TCP 1200 and connect a remote control unit. Pin
assignment of the connector according to table.
Shielded connectors and cables must be used.
The following information display the factory setting. Configuration is possible
using the Pfeiffer Vacuum parameter set.

+24 V DC* Output / Pin 1
Inputs 2 - 6 and the connections to Pins 10, 13, 14 are activated by connecting them with
+24 V DC to Pin 1 (active high). They can also be activated via an external PLC. The
functions are deactivated by "PLC high level" and by "PLC low level".
