Alarm Relay - Grundfos Conex DIA-G Instrucciones De Instalación Y Funcionamiento

Measured value: Display example of measured
value, Sensor 1.
Sensor 1
xx.xx ppm
xxxx nA
xxxx.x nA/ppm
The following data is displayed:
• xx.xx ppm = Current measured value in ppm
• xxxx nA = Current input current in nA or µA
• xxxx.x nA/ppm = Sensor sensitivity in nA/ppm or
µA/ppm.
Auto test: The current set test interval and the
remaining time until the next sensor test is displayed.
This menu only appears if the automatic function has
been selected in the main menu under "Sensor 1" or
"Sensor 2".

• Interval: Displays the preset test interval. See
also 11.9.1 Sensor test.
• Next test: Displays the remaining time in days
and hours until the next automatic test function.
Sensor data: Sensor-specific data is displayed.
The replacement date is displayed according to the
calibration date (EPROM) and installation date
(detection of new sensor). See section

Test current (check operation of the current
outputs)
Depending on the configuration of the current loops,
the current outputs can be switched on with the
following current values, and the current value can
be output to the system:
• Selection of 0, 10, 20 mA when standard range
0-20 mA is selected
• Selection of 4, 12, 20 mA when standard range
4-20 mA is selected or for freely configured
current loops
1. Access the "Test current" menu by pressing [OK].
2. Access "Current output 1" for sensor 1 or
"Current output 2" for sensor 2 by pressing [OK].
3. Press the [Up] or [Down] button to select the
current values.
4. Select the row, and press [OK] to set the status of
the current output with the relevant value to "On".
5. Select another row, and press [OK] to switch off
the previous current value and set the new
current value to "On".
6. For every current value, use a suitable measuring
device to check that current is present at the
relevant current output.
– If the relevant current value is present:
Function is OK.
– If the relevant current value is not present: The
current output is faulty.
7. Press [Esc] to exit the test menu. When you exit
the menu, the latest current values for the
sensors are output to the system again.
