Your Benefits
■ Avoid tripping with clear
instructions in the case of
an alarm
■ Associated Faceplates for
an intuitively correct
response to trip alarms
■ Intelligent alarm focusing
to prevent plant operator
overload
■ Increased plant availability
and profitability
The SPPA-T3000 Trip Stop buttons
are an extra alarm class for trip avoidance.
Clear instructions and Faceplates at the click of
a mouse button for a fast and reliable reaction
to avoid plant trip.
The Task
Managing unpredictable disturbances, which
arrive with little or no warning and require
accurate decisions and operator actions within a
matter of seconds, is probably the most difficult
– and expensive – part of operating a power
plant. In certain cases, an automatic shutdown
may occur if the response is too slow or
incorrect.
To solve this problem, it is necessary to filter out
emerging disturbances which may cause a plant
trip from the general stream of messages,
presenting them separately and flagging them
up both acoustically and optically. Operators
also need clear instructions to facilitate a fast
and accurate reaction even when working
under time pressure.
Our Solution
Trip Stop buttons add an extra alarm class to
SPPA-T3000. Two new selection buttons in the
control bar – "Trip Warning" and "Trip Stop" –
help operators recognize and manage disturbances with the potential to cause a trip.
general stream of messages and presenting
them separately. The operator is then notified
of the trip-relevant messages both optically and
acoustically.
The Trip Stop button gives the alarm in really
critical cases in which there is no forewarning of
a trip but rather a sudden disturbance
demanding an immediate response.
The operator has only seconds in which to take
action in scenarios of this type, so the Trip Stop
button comes with concise predefined
instructions for trip avoidance. This makes it
possible to resolve the situation with a single
mouse click in the associated Faceplate.
Operators paying attention to these two
selection buttons have everything important for
trip avoidance at their fingertips. Currently the
most advanced type of alarm focusing and trip
avoidance, this filtering method can be
integrated into both new and existing plants as
required.
The new SPPA-T3000 user interface: Safe and efficient
operation today and in the future with touch-capable design.
The "Trip Warning" selection button evaluates
trip-relevant scenarios and generates warnings
to which the operator needs to attend as a
matter of priority in order to avoid trips. This
entails analyzing possible disturbances affecting
the core components, filtering them out of the
Answers for energy.
“Trip Warning“ und “Trip Stop“
The two selection buttons define a new
category of alarm class. Providing
intelligent alarm filtering and instructions
in the event of a critical alarm, they make
the operator's job noticeably easier in dayto-day operation.
■ Audible and visible alarm
■ Predefined instruction for intuitive
reaction with Faceplate
■ Audible and visible alarm
■ Predefined trip-scenarios
■ Analysis of possible faults and core
components
Trip Warning (TW)
A list of trip-relevant warnings that are to
be attended as a priority. A modern form
of user guidance, this intelligent alarm
focusing method helps to reduce stress in
the control room.
Trip Stop (TS)
User guidance for urgent alarm events.
Clear instructions, clear Faceplates and
clear guidance: the key assets for trip
avoidance.
