7.18 Warnings
The Softstarter has a number of warning functions to
signal malfunctioning or other potential risks, before
asserting the protection or fault. The difference between
a warning and a protection is that a warning cannot stop
the Softstarter and a reset of a warning is not necessary.
The warning level and all other additional information to
enable the warning can be set by the user.
A warning is stored in the event list. Warnings can be
Enable or Disable. There is sometimes a percentage
setting were the user can set at which percentage level
the warning occurs.
Set warnings to an Event group by the Out parameter.
The Event group can be set for relay output to control
other devices in an application.
As default, all parameters are set to the same
Eventgroup.
Warnings show on the HMI, but do not change the
behavior of the Softstarter.
