The Pfeiffer Vacuum parameter set
19
* Only when using pumps with Temperature Management System TMS
6.3.2 Accessory connection
Configuration via parameters [P:035] or [P:036].
The standard version electronic drive unit TC 110 only can control two accessory ports
via connection cable. Therefore the parameters [P:037] and [P:038] are ineffective.
6.3.3 Analog output on "X3"
Configuration via parameter [P:055].
6.3.4 Control via interface
Configuration via parameters [P:060] and [P:061].
14 = Sealing gas Control is equal to parameter [P:050]
15 = Pumping station Control is equal to parameter [P:010]
16 = Pump rotates Active, if rotation speed > 1 Hz
17 = Pump does not rotate Active, if rotation speed < 2 Hz
18 = TMS engaged* Active, if TMS set temperature is engaged
19 = Pressure switchpoint 1 underrun Control is equal to parameter [P:730] ([P:740] < [P:730])
20 = Pressure switchpoint 2 underrun Control is equal to parameter [P:732] ([P:750] < [P:732])
21 = Fore-vacuum valve, delayed + 24 V DC time delayed after pumping station on
Option Description
Option Description
0 = Fan (continous operation) Control via parameter Pumping station
1 = Venting valve, normally closed Control via parameter Enable venting, when using a venting
valve which is normally closed.
2 = Heating Control via parameters Heating and Rotation speed switch-
pont attained
3 = Backing pump Control via parameters Pumping station and operation
mode backing pump
4 = Fan (temperature controlled) Control via parameter Pumping station and temperature
thresholds
5 = Sealing gas Control via parameters Pumping station and Sealing gas
6 = always 0 GND for the control of an external device
7 = always 1 +24 V DC for the control of an external device
8 = Power failure venting unit Control via parameter Enable venting, when using a power
failure venting unit.
12 = second venting valve Control via parameter Enable venting and underrunning 50
% of the nominal rotation speed, when using a venting valve
which is normally closed.
Option Description
0 = Rotation speed Rotation speed signal; 0 - 10 V DC = 0 - 100 % x f
Nominal
1 = Power Power signal; 0 - 10 V DC = 0 - 100 % x P
max
2 = Current Current signal; 0 - 10 V DC = 0 - 100 % x I
max
3 = always 0 V always GND
4 = always 10 V output of continously 10 V DC
6 = Pressure value 1 Pressure value signal;
0 V: error
1 V: underrange
1,5 - 8,5 V: p (hPa) = 10
(U-5,5 V)
9 V: overrange
7 = Pressure value 2
8 = Control fore-vacuum Fore-vacuum signal; control of Pfeiffer Vacuum
turbo pumping stations
Option [P:060] Description
1 = remote Operation via connection "remote"
2 = RS-485 Operation via connection "RS-485"
4 = PV.can For service purposes only
