Manual flush mode
●
For each installed filter there needs to be a possibility to manualy flush the filter.
●
The manual flush cycle needs to be identical to the automatic flushing cycle.
General
●
When the system, in which the filter is installed, is not operational, it may not start an automatic flushing cycle.
●
Make sure that the filter is flushed based on operational uptime. The manual flush cycle needs to be identical to
the automatic flushing cycle. No matter how the flushing cycle was started the interval to the next cycle will
start to be measured again after each ending of a flushing sequence.
●
Connect de DP-switch directly to the IO board of the PLC of computer (without routing through a relay).
Advise
●
Generate an alarm if a flushing cycle is repeated directly after another multiple times (for instance 3 times).
●
Make sure that the amount of flushing cycles per day are logged. It is recommended to distinguish the various
possiblies that can initiate a flushing cycle
●
Make sure the following parameters are changable:
�
Pre-Dwell time (sec.)
�
Length of flushing cycle (sec.)
�
Dwell time (sec.)
�
Time interval for flushing cycle (hrs)
�
Amount of filters installed
�
Main valve installed (Yes/No)
�
Main valve time delay (Sec.)
●
Flush the filter before or after a duty cycle. (Clean start and clean stop)
●
Use an UDI controller for standalone applications.
