Verifying the settings
Prepare the terminal for verification of settings as outlined in
this chapter.
Procedure
1.
Configure the HMI--BLOCKSET functional input to the binary input,
which is determined by the engineering or the input that is not used
by any other function.
2.
Set the setting restriction to SettingRestrict = Block.
3.
Connect rated DC voltage to the selected binary input.
4.
Try to change the setting of any parameter for one of the functions.
Reading of the values must be possible.
The terminal must not respond to any attempt to change the setting value
or configuration.
5.
Disconnect the control DC voltage from the selected binary input.
6.
Repeat the attempt under
The terminal must accept the changed setting value or configuration.
7.
Depending on the requested design for a complete REx 5xx terminal,
leave the function active or reconfigure the function into the default
configuration and set the setting restriction function out of opera-
tion to SettingRestrict = Open.
Completing the test
Continue to test another function or complete the test by setting the test mode to off. Restore
connections and settings to the original values, if they were changed for testing purpose.
