Regardless of whether Load Control is activated or not,
the thermal overload protection protects the affected
output from damage.
Activating Load Control enables a management function which
in case of overload can turn the affected outputs OFF and
notify the user.
For hardware reasons, load monitoring is done in pairs, i.e.,
always for two outputs at a time, for example Output 0 and Out-
put 1. Depending on the state of the outputs and the error type,
the Web-IO may not be able to definitively determine which
output is responsible for the error. In this case both outputs
are set to OFF.
Also monitored is whether any load at all is present. If the Web-
IO can definitively determine that the error represents the
absence of a load, Load Control is deactivated (only) for this
pair of outputs.
By clicking on the Delete report button under Diag >>Report
the Administrator can turn the outputs back on.

Load control, the physical wiring of the affected outputs
must in any case be checked before they can be enabled again.

Overload errors can also be configured as triggers for
an alarm. See section on Alarms.
