The Flush Time
Defines the duration of the flushing time per station. The following options are selectable:
5-20 sec in steps of 1 sec
20-55 sec in steps of 5 sec
1-6 min in steps of 0.5 min
The DP Set Point
At this field the user defines the pres
sure difference between the filter’s inlet and outlet that when
reached, a flushing cycle will take place. This field is meaningless when electronic DP sensor is not in
use, therefore the user is expected to define the DP set point to be 00, as a result the actual DP value
will appear as (- -).
When the pressure is expressed in BAR the range of values is 0.1
– 2.0 BAR.
When the pressure is expressed in PSI the range of values is 1- 30 PSI.
When the system does not include the built in electronic DP sensor but uses instead an external DP
sensor, the flushing request signal arrives in the shape of a closed dry contact at the appropriate input
terminals.
The Flush Mode
The Flush Mode defines how the flushing cycles is triggered. The selectable options are as follows:
OFF
-
no flushing will take place
By time
–
In this case the flushing cycles will be repeated in a selected interval or will be triggered
by the DP signal depending on what happens first. No matter how was the flushing
cycle started the interval to the next cycle will start to be measured again after each
ending of a flushing sequence. The selectable intervals are the following:
5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 minutes
2, 3, 4, 5, 6, 8, 12, 18, 24, 72, 120 hours
dp
–
flushing will be triggered by DP only.
If the “+” and “-“ keys are pressed and held down simultaneously the
“Flush Mode” field will show the left time until next cycle, alternately hours
and minutes.
The Accumulations
The unit accumulates and displays the number of flushing cycles caused by DP, by time, or manually
At each of the accumulation fields,
the “+” or “-“ keys may be used for clearing the accumulated value.
The Configuration
In order to enter into the configuration process press and hold down the ENTER key for at least 3
seconds.
