Operation
For operation without the control unit, the 26-pole D-Sub plug must be in the "
remote
"
connection on the TC 400.
Switch on the supply voltage with switch S1 on the power supply.
After operating voltage is applied, the TC 400 performs a self-test to check the supply
voltage. Once the self-test has been successfully completed on the TC 400, the tur-
bopump and the backing pump - if connected - begin to operate.
Operation via
"
remote
" connection
Remote control options are provided via the 26-pole D-sub connector with the designa-
tion ”
remote
“ on the electronic drive unit.
Consider the following manuals for the operation via remote control:
●
Operating instructions "Electronic drive unit TC 400"
Operation with DCU
or HPU
Consider the following manuals for the operation via Pfeiffer Vacuum display and con-
trol units:
●
Operating instructions "DCU"
●
Operating instructions "HPU"
●
Operating instructions "Electronic drive unit TC 400"
Switch on the supply voltage with switch S1 on the power supply or on the DCU 400.
Settings are possible via the RS-485 by using DCU, HPU or PC.
Operation via field
bus
Integrating and operating Pfeiffer Vacuum turbopumps in the customer's field bus system
is possible for electronic drive units with a corresponding field bus panel.
Consider the following manuals for the operation via field bus:
●
Operating instructions for the electronic drive unit with the respective connection

Monitoring of the operation conditions
Operating mode dis-
play via LED
LEDs in the front panel of the electronic drive unit show basic operating conditions of the
turbopump. A differentiated malfunction and warning display is possible only for opera-
tion with DCU or HPU.
Temperature monitor-
ing
The drive power is reduced in case of impermissible motor temperature or impermissibly
high housing temperature. This can cause falling below the rotation speed switchpoint
and so result in turning off the turbopump.
