ABB EL3060-Uras26 - Analog Output Test Procedure; Testing Analog Output Functionality

126 EL3060 CONTINUOUS GAS ANALYZERS | OI/EL3060-EN REV. A
The test of the digital outputs is ended by pressing the key or after ap-
prox. 5 minutes through the time-out function (see page 50); all digital out-
puts are thereby reset to the status "OK" and the status signal "Maintenance
mode" is canceled.
Test of the analog outputs
The analog outputs (AO) available in the analog output modules (see page
39) installed in the instrument are shown in the list. They are named accord-
ing to the installation locations of the analog output modules (X20, X22, X24,
X26).
Test:
1 Remove the connector with the connected signal lines from the analog
output module.
2 Select the analog output to be tested with
or .
3 Call up the value change with .
4 Change the displayed value digit by digit with
or and confirm the
change with OK.
Result: the current signal at the analog output changes its value, the
status display changes from "OK" to "Test", and the status signal
"Maintenance mode" is output.
5 Either test another analog output in the same way or reset the tested
analog output.
The test of the analog outputs is ended by pressing the
key or after ap-
prox. 5 minutes through the time-out function (see page 50); all analog out-
puts are thereby reset to the status "OK" and the status signal "Maintenance
mode" is canceled.
