“E-Yesterday” compared with “E-Average”.
If “E-Ratio” falls short of the value stated for “Tolerance”, the error message
“Energy” is generated.

“Tolerance” refers to the time span set under “Warnings” in
“Setup…System…Tolerances” (refer to section 6.2.4). A warning message will be
generated only if a failure lasts longer than this amount of time.
“State” and “Failures” show the current operating status of the device. If
“Failures” deviates from the setting “-----” (no error), the time passed since the
failure occurred is given below “occurs for”. If “occurs for” exceeds the
“Tolerance” value, the warning message “Device failure” is generated.

“RIso” refers to the current insulation resistance of the device. If the “RIso” value
falls short of the value set for “Tol.Warn.”, a warning message is generated; if it
falls short of the value set for “Tol.Fail.”, an error message is generated.
