Connection "
X3
"
Remote control options and voltage supply are provided via the 15-pole D-sub connector
with the designation ”
X3
“ on the TC 110.
Shielded connectors and cables must be used.
The following information display the factory setting. Configuration is possible
using the Pfeiffer Vacuum parameter set.

" connection
Voltage supply
+24 V DC Input / Pin 1
The electrical connection at "
X3
" is carried out via connecting cables of the Pfeiffer Vac-
uum accessories program or by customized configuration on Pin 1 and Pin 15.
+24 V DC* Output / Pin 7
Inputs 2 - 6 are activated by connecting them with +24 V
DC to Pin 7 (active high). They
can also be activated via an external PLC. The functions are deactivated by "PLC high
level" and by "PLC low level".
●
PLC high level: +13 V to +33 V
●
PLC low level: -33 V to +7 V

NOTICE
Danger of the drive unit being destroyed
Cutting the plug connection "
X3
" can lead to the destruction of the electronic drive unit,
when the power supply is still switched on.
Before pulling the connector "
X3
" necessarily disconnect the power supply.
Switch off the power supply unit.
