5.7 Selector
This screen enables the use of various fertilizer stock tanks. Every dosing program can be connected to one (or more)
selectors. Using the selector outputs you can choose which fertilizer stock will be connected to each dosing program.
Use the '+/-' keys to assign a selector to a dosing program.
5.8 Filter Flushing
Configuring the required process for filter flushing is allowed. Define the following before configuring this screen:
• Stop Irrigation During Filter Flushing
: Yes/No
• Stop Dosing During Filter Flushing: Yes/No
• Time Between Flushing (hh:mm): Time interval between two consecutive Flushing cycles. The time is only
counted during irrigation.
Example: If the time between flushing is set to 01:00 it means that a flushing cycle will be activated after 1
hour of irrigation (regardless of DP status).
If set to zero (--:--), flushing will only take place if triggered by a DP.
• Flushing Time (mm:ss): Flushing time of each Filter (output).
• Delay Between Filters (mm:ss): The delay time between flushing of one filter to the next. This time is usually
used to allow pressure buildup.
• Delta Pressure (Digital): Define whether filter flushing can be triggered due to digital Delta Pressure (Yes /
No).
• Delta Pressure Value (bar): Define the Delta Pressure of the inlet pressure sensor (Pin) and outlet pressure
sensor (Pout), at which filter flushing will be triggered (Only relevant when the application consists of analog
Pin and Pout sensors).
• Delay Delta Pressure (mm:ss): Define the time that the Delta Pressure (digital or value) must be active
before a filter flushing cycle will be triggered. This time is usually used to prevent unnecessary flushes from
taking place.
