Power Derating Function - Agilent Technologies TwisTorr Medium-TMP Rack User Manual

Technical Information

Power Derating Function

An enhanced power derating is implemented to provide the following benefits:
Immediate auto-detection of changing requirements in the application.

Dynamic TMP performance adapting to application conditions for customer's

process stabilization and speeding-up.
Always the best "tuning" for TMP pumping technology taking the complete

advantage of TwisTorr technology potential.
Pump components minimized stress by mean of continuous TMP parameters

tuning for extended reliability.
The enhanced power derating dynamically adapts per the following functioning
parameters:
Gas type load (selectable WIN 157: see the following "Window Meanings"

paragraph).
Cooling mode (selectable WIN 106: see the following "Window Meanings"

paragraph).
Actual Pump temperature (can be read by WIN 204).

Actual Driving Frequency (can be read by WIN 203).

Refer to the PUMP manual for further description.
The user must set the gas type load (WIN 157) and Cooling mode (WIN 106)
WARNING
before starting the pump.
The applied power limit is readable by serial line (WIN 155).
If the pump body temperature exceed 55 °C or the pump bearing temperature
exceed 60 °C or the Controller temperature exceed 60 °C, the controller goes in
status 6 (Fail).
