Electrical Supply Failure - Edwards T-Station 300 Instruction Manual

6.4 Electrical supply failure

WARNING: IMPELLER SPIN
Risk of injury or death. If the power supply fails when the pump is running, the
impeller could continue to spin for approximately 10 minutes. The control circuit may
not give any indication that the impeller is still running.
If the electrical supply to the pumping system fails when the turbo pump is rotating, the
motor of the turbo pump is used as a generator. The regenerated power is used to
maintain the control system and the display. The regenerated power is not used to
maintain the pumping system control system or the display.
When power to the control system is lost, no indication will be given about pump
rotational speed, yet the impeller may still be turning.
The system will not restart when the power is reinstated.
