Applications which can be implemented with the aid of the serial interface:
Application
Benefits to the customer How to do it
Networking of several pumps
and other equipment
Savings relating to the costs for sig-
nalling cables
With Field Bus systems
Automation Savings related to repetitive manual
work
For example by a control computer
Avoidance of warnings and
warnings before overload
operation and early detection
of a failing pump
n Precise planning for maintenance
n Improved reliability of sensitive pro-
duction processes in a vacuum
Monitoring of:
n Motor current P5
n Motor temperature P7
n Frequency converter temperature P11
Standby operation
n Cutting process gas consumption
n Cutting energy consumption
Reducing the rotor’s frequency through P24
Troubleshooting Quick analysis of problems Reading of error memories P171, P174 and P176: error
code, speed, operating hours for error
Read out warning messages through P227
Slow pressure control by
changing the pumping speed
Dispensing with a flow controller Changing the rotor frequency through parameter 24
Starting the pump with a
delay if several consumers
are connected to the same
PSU
Cost savings through smaller power
supply units if peak loads can be
reduced
With P36, delay
Lowering the normal opera-
tion threshold
Normal operating mode is attained
faster, processes can be started faster
Reduce frequency threshold through P25
Only for TURBOVAC iX:
Switch the fan depending on
temperature or frequency
Saving of electricity, reduce noise,
optimise the pump temperature for the
process
Configure accessory connection (X201, for example) cor-
respondingly, for example, enter function code 30 in
parameter 134[0] and set up the temperature limits in
parameter 122[0] and 26[0].
Only for TURBOVAC iX:
Individually adapt venting and
purge gas (active venting,
adaptation of the delay time
etc.)
Save gas, process speed-up Correspondingly configure the function code for an
accessory connection (X203, for example)
Control cooling water flow Avoid condensation during cooling
water operation
Connect cooling water valve at accessory connection
(X201, for example)
Enable generator operation
(power backup mode)
The power produced by the pump
when running in the generator mode
may be used for other electrical con-
sumers and the pump is also decele-
rated faster.
With P249
This function is only changed after de-energising the
pump and then restarting it.
Only for TURBOVAC iX:
Changing the function of the
accessory outputs
Different applications for connected
accessories
Configure the accessory connection, see interface
