Perform Calibration; Input Of The Lower Conductivity Limit; Input Of The Upper Conductivity Limit; Test Of The Relay Functionality - Igema FARB2 Installation And Operating Instructions Manual

7.4.5 Perform calibration

In menu item 2.5. the display shows
Press the "OK" key again to calculate the entered values from 2.3 and 2.4 together with the current
measured value. The display shows "ok". Press the
Current output, relay and display are set accordingly.

7.4.6 Input of the lower conductivity limit

In menu item 2.6. after confirming with
entered. The factory setting is "2000".
"2.000", the decimal point flashes at the first digit. This can be changed with the arrow keys. The entry
is confirmed with "OK"; display now shows: "20.00".
The 2nd decimal point can be changed with the arrow keys.
The other values are programmed in the same way.

7.4.7 Input of the upper conductivity limit

In menu item 2.7. after confirming with
entered. The factory setting is "5000".
"5.000", the decimal point flashes at the first digit. This can be changed with the arrow keys. The entry
is confirmed with "OK"; the display now shows "50.00".
The 2nd decimal point can be changed with the arrow keys.
The other values are programmed in the same way.

7.4.8 Test of the relay functionality

In menu item 2.8. "test"
If you press "OK" again, the relay is switched to the deenergised state.
This test checks whether the relay still switches.

7.4.9 Programming the conductivity value for 4mA current output

In menu item 2.9. after confirming with "OK", enter the conductivity value at which the 4..20mA current
output should be 4mA. The factory setting is "0000".
"0.000", the decimal point flashes at the first digit. This can be changed with the arrow keys. The entry
is confirmed with "OK"; the display now shows "00.00".
The 2nd decimal point can be changed with the arrow keys.
The other values are programmed in the same way.
"CALI" after you confirm with "OK".
"OK"
"OK"
is displayed after confirmation with "OK".
"OK" key again to switch to normal operating mode.
the value for the lower conductivity switching point is
the value for the upper conductivity switching point is
