inactive).
–> Set values are saved.
6.10. Keys Lock
The keys at the front panel of the TCP can be locked against
unauthorised operations.
Activating Keys lock
➡ Select «
779944:: PPaarraamm sseett
»; choose «
11
».
➡ Select «
000088:: KKeeyyss lloocckkdd
»; choose «
OONN
».
Deactivating Keys lock
The keys can only be de-activated via interface RS-232/-485
[[PP::000088]]
or via mains OFF/ON. For deactivating keys via mains
OFF/ON, the TCP must be switched off currentless during
turbopump is at rest (f=0 Hz).
6.11. Venting the Turbo Pump
Venting can only take place after the pumping station has
been switched off.
The venting valve is closed when de-energized. In the event
of a malfunction, venting may take place, depending on which
venting mode was selected.
The extended parameter set is used to choose between three
venting modes:
➡ Call «
779944 :: PPaarraamm sseett
»; select «
11
».
➡ Call «
001122 :: VVeenntt eennaabb
» ; select «
OONN
».
➡ Call «
003300 :: VVeenntt mmooddee
»; select «
00
», «
11
» oder «
22
».
Venting mode «0»: Automatic venting
Automatic venting means that venting commences at a set
frequency
[[PP::772200]]
for a set time
[[PP::772211]
]
after the pumping
station has been switched "OFF" or after power failure. The
set time cannot be guaranteed in the event of power failure.
➡ Select «
772200 :: VVeenntt ffrreeqquu
».
➡ Set the venting frequency within the range «
4400--9988%%
».
➡ Select «
772211 :: VVeenntt ttiimmee
».
➡ Set the venting time in seconds within the range «
00
» and
«
33660000
».
–> The venting valve is closed after “
PPoowweerr OONN
”.
Venting mode «1»: Venting OFF
–> The pump is not vented.
Venting mode «2»: Venting ON
–>Venting takes place after a delay of 6 s when “Pumping
station OFF”, if a malfunction occurs or on power failure.
During this delay time, any high vacuum valve present can
be closed. In the event of power failure, venting will only
last for as long as the pump energy can continue to feed
the venting valve. The venting valve remains open after
power “ON”. It closes when the pumping station is
switched on.
6.12. Operation Using Interface RS-485
The group address of the TCP 3000 is 992. Different interface
addresses must be selected
[[PP::779977]]
for all the units
connected to the bus.
Data communication is described in Operating Instructions
PM 800 488 BN.
6.13. Emergency Generator Operation
If the power supply fails (Warning F007) whilst the turbo pump
is in operation, the pump rotor acts as a generator and
supplies power to the electronics. Power failure is also
indicated by flashing green and red LED's on the front panel
(50 % ON; 50% OFF). At a particular rotation speed (depending
on the pump), the pump energy will no longer suffice, at
which point the TCP 3000 will be shut down completely.
6.14. Configuring the Analog Output
An analog signal (0-10 V DC) can be tapped at the TCP 3000,
with the following information:
- Rotation speed of turbo pump
- Capacity
- Power input.
To this aim, the analog output must be configured in
accordance with its function:
➡ Call «
005555 :: CCoonnff.. AAOO11
».
➡ Select function
00
,
11
oder
22
:
0 = Rotation speed signal, 0-10 V DC = 0-100 % x f
end
1 = Capacity signal, 0-10 V DC = 0-100 % x p
max
2 = Current signal, 0-10 V DC = 0-100 % x I
max
For information about the values f
final
, p
max
and I
max
, please
refer to the operating instructions of the turbo pump you are
using.
