Operation
13. On the display, check the feed pressure, differential pressure, and brush speed to ensure the
system is operating normally.
14. Observe the filtrate valve position and ensure it reaches the open % setpoint or is tracking the
differential pressure setpoint.
4.2 Shutdown
The system has 3 shutdown modes; standard shutdown,
alarm shutdown, and emergency shutdown.
•
Standard shutdown is triggered through the HMI or a
network input. The system will shutdown in the best
possible way by performing a cleaning cycle, purging
the concentrate, and closing all valves before stopping
the pumps. Password is required.
•
Alarm shutdown is triggered by alarms or faults in the
system. It will shutdown in the quickest possible safe
method by closing all valves and then stopping the pumps.
•
The emergency shutdown is triggered by the emergency stop signal. The system will immediately
stop all pumps and close all valves. This will open the opportunity for damage to the filter and
should only be used in actual emergencies.
4.3 Long-term Shutdown
If the system is being shut down for an extended period of time (over 24 hours), it is best to drain the
system.
1. Press the Stop button on the Home screen to shut down the controller. Wait for the system to
completely stop.
2. Close the feedwater valve and concentrate return valve.
3. Open the air bleed valve to permit air to enter the filter housing.
4. Open the valve at the bottom of the recirculation pump.
Note:
If this valve is left open after draining the system, it is a good idea to tag the valve so it is not
forgotten when the system is later restarted.
5. Open the service drain valve.
6. Allow the system to fully drain.
7. Power down the controller.
8. For very long-term storage beyond 7 days additional steps must be taken.
•
The filter and cleaning assembly must be removed, cleaned, and stored in a dry location.
•
Flush the skid and filter housing with clean water to purge all settled solids.
•
O-rings must be cleaned and lubricated.
•
Valves must be cycled to ensure solid build up has not solidified on the valve faces.
•
Any areas isolated from normal drainage must be disassembled and drained of water.
