7.16 Warnings
The softstarter is equipped with 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 any other additional
information needed to enable the warning can be set by
the user.
A warning will be logged in the event list when it occurs.
Warnings can be Enable or Disable. There is also a
percentage setting were the user can set at which
percentage level the warning shall occur. The percentage
setting is within 10 - 80 %.
Warnings can be set to an Event group by a parameter
option called Out. The Event group can be configured for
relay output to control other devices in an application.
As default, all parameters are set to one Eventgroup.
Warnings are displayed on the HMI, but otherwise they do
not affect the behaviour of the softstarter.
