Wash time
Defines the duration of the wash time per station. The following options can be selected:
5-20 seconds in 1 second intervals
20-55 seconds in 5-second intervals
1-6 minutes in 0,5 minute intervals
7.5
DP preset value
In this field the user defines the value of the pressure difference between the inlet and outlet of
the filter that, when reached, will cause the beginning of the wash cycle. This field appears only
when the system includes the electronic DP sensor.
When pressure is expressed in BAR, the range of values is 0.1 - 2.0 BAR. When pressure is
expressed in PSI the range of values is 1-30 PSI.
When the system does not include the electronic PD sensor. but an external PD sensor is
connected, the flush request signal comes in the form of dry contact.
7.6
Wash mode
The wash mode defines how the wash cycles will be triggered. The options are as follows:
●
OFF
- There will be no washing
●
By time
- In this case the wash cycles will be repeated at a selected interval or triggered
by the DP signal depending on which occurs first. No matter how the wash cycle started,
the interval to the next cycle will start to be measured again after each end of the wash
sequence. The selection ranges are as follows:
-
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
- the wash will be triggered by DP only.
-
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
- the wash will be triggered by DP only.
* If the "+" and "-" keys are pressed and held simultaneously, the "Wash Mode" field will show
the time remaining until the next cycle, alternatively, first hours and then minutes.
7.7
Accumulations
The unit accumulates and displays the number of wash cycles caused by DP, by time, or
manually. In each of the accumulation fields, the "+" or "-" keys can be used to clear the
accumulated value.
