12.3 System Power Loss and Responses
12.3.1 System Power Loss
If power is lost while the System is running, all power and control components are de-energized. The
pump motors coast to stop, back-pressure control valves are reset to 0%, and an alarm is triggered.
The active process sequence is put into a hold state.
The PC and HMI remain shut-down.
12.3.2 Restarting the System after a Power Loss
When possible during a power failure, it is recommended that the System main power disconnect
switch be turned off to facilitate the following power up sequence:
1. Ensure the System is safe to start.
2. Turn the main power disconnect switch to the “On” position.
3. Rotate and pull out the emergency stop button.
4. Press the blue Master Reset button.
5. At startup, the KrosFlo System will display all alarms as being active; they should be
acknowledged, and a reset should be performed to clear any latched faults before
operating the KrosFlo System
Note:
• If the power loss is brief, the System may be able to continue without any disruptions.
• When power is restored, the System will automatically power up to the point where the
active sequence was put on hold, but users need to press the Master Reset button.
However, it is always recommended to follow the restarting procedure above instead.
12.4 Shutting Down the System
To shut down the System:
1. To perform a system power down, click the Exit function ( ) on the Secure Desktop.
2. After the HMI shuts down, execute a power down from the Windows Login screen.
Note:
• After Windows shutdown, power down the System by turning the main power
disconnect counterclockwise to “Off” position.

or electrical connections after a power lost.
