7.2.8 Function switch: position 6. Proof test - self-test
Before and after the automatic proof test, it is essential to check whether the level
value displayed corresponds to the actual level value
2)
.
When the self-test is activated, the current output is set to 4 mA and follows a ramp
function up to 22 mA. This test is completed after 40 s.
To activate the device self-test:
1. Turn the function switch to position 6.
2.
Press  and  keys together to start the function test.
 The green LED flashes quickly until the current error is reached.
The red LED flashes until the test is completed.
After the self-test, the device automatically returns to the operating mode.
7.2.9 Function switch: position 7. Reset - restore factory settings
The reset can affect the measurement as the current values are overwritten by the
factory values of calibration 0% (4 mA) and 100% (20 mA).
To restore the factory settings:
1. Disconnect the electronic insert from the power supply.
2. Turn the function switch to position 7.
3.
Press and hold the  and  keys together while the device is being reconnected to
the power supply.
 Red LED flashes slowly and then starts to flash quickly.
4. Wait until the red LED stops flashing.
5.
Release the  and  keys.
7.2.10 Function switch: position 8. Download or upload sensor DAT
(EEPROM)
Calibration values can be transmitted with this function.
A distinction is made between two types:
• the sensor has been replaced and the electronic insert should continue to be used
• the electronic insert has been replaced but the sensor should continue to be used
The calibration values already set can be transferred from the sensor to the electronic
insert or from the electronic insert to the sensor.
Download
To transfer the calibration values from the electronic insert to the sensor:
1. Turn the function switch to position 8.
2.
Press the  key to start downloading from the electronic insert to the sensor.
 The green LED flashes for 2 s, confirming your entry.
The device restarts.
Upload
To transfer the calibration values from the sensor to the electronic insert:
1. Turn the function switch to position 8.
2) This applies from version FW: V 01.03.00
