Set Pressure:
Set pressure is the pressure value at which the system is expected to work.
In booster pump mode, it is associated with the value read off of pressure transmitters.
In circulation mode, it is associated with the difference between the values read off of
transmitter1 and transmitter2.
Maximum Pressure:
Maximum pressure is the pressure value corresponding to the 20 mA
maximum value on pressure transmitters. A standard selection between 10, 16 and 25 bars
can be made on the screen.
Sensor Selection:
Sensor1 is selected as the factory setting in booster pump mode. If
the Sensor1 port belonging to the EPLC-6 is damaged, Sensor2 can be selected from the
menu after the pressure transmitter is connected to the Sensor2 port. If a transmitter
is connected to both ports and Automatic is selected, the system continues operating
according to the value read off of Sensor2 without stopping when Sensor1 is damaged.
Sensor1- Sensor2 is selected as the factory setting in circulation mode. Sensor1 or Sensor2
cannot be selected alone in this mode. However, if Sensor2 is not connected or cannot be
reached when Sensor1- Sensor2 is selected, the system will issue a warning and continue
operating according to the Sensor1 value. If Sensor1 is not connected or cannot be reached,
the system is blocked.
Sensor Calibration:
Through the sensor calibration settings, any difference between the
pressure value from transmitters and the actual pressure value of the fixture can be fixed. If
the pressure value seen on the main screen is considered to be incorrect, it can be checked
as follows; when the pressure value of the fixture is 0 but the value shown
in the rightmost box is not 0, the
symbol can be tapped to set the pressure value
in the fixture to 0. If the pressure of the fixture is not 0, the sensor maximum settings are
selected correctly but the pressure value collected from the manometer is incorrect, the
value in
to the right of the
symbol can be increased or decreased at
the rate of 20% to match the pressure value of the fixture and the pressure value shown on
the main menu. This process can be done separately for each of the two sensors.
Maximum Protective Pressure:
A maximum pressure is set through this parameter to
protect the system from high pressure conditions. If system pressure is higher than the
Maximum Protective Pressure throughout the set Maximum Protective Pressure Period,
the system will enter high pressure protection mode and all operating pumps will halt. If
the system pressure falls below the set value, the system will start operating again which
means that the system will resume operating once the working conditions have been
suitably met.
4.4 Protection Settings:
The maximum and minimum pressure
values and the time period required
for the activation of these protective
pressure properties can be adjusted in the
"Protection Settings" menu. As a result, the
system is protected from working under
damaging pressure conditions, cavitation
or operating without water.
