Setting Entry Error Messages
As you enter relay settings, the relay checks the setting entered against the
setting’s own range as published on the relay setting sheet. If an entered setting
falls outside its range, the relay immediately responds with the message “
Out of
Range
”
and prompts you to reenter the setting.
In addition to the immediate range check, several of the settings have
interdependency checks with other settings. The relay checks setting
interdependencies after you answer
Y
to the “
Save Settings?
”
prompt, but before
the settings are stored. If any one of these checks fail, the relay issues one of the
error messages shown in the Table 5, and returns you to the settings list for a
correction.
