3UF5 SIMOCODE-DP System Motor Protection and Control Device

Extensive Diagnostics
SIMOCODE-DP offers a large amount
of operational and statistical data on
the feeder, which is available to the
user for visualisation and diagnostic
purposes.
This data can be accessed:
• directly at the switchboard via the
LED display of the hand-held-unit
plugged into the basic unit or
operator panel, or via a PC with
Win-SIMOCODE-DP/Smart.
• via PROFIBUS-DP. The data can be
read by the user program and it can
be transferred to a corresponding
operator communication and
monitoring system. Thus, the various
operational and statistical information
can be displayed in the control room
• over PROFIBUS-DPV1 with a
communications processor which
were in the PC/PU and the software
Win-SIMOCODE-DP/Professional
Always informed as to the current
operating state
SIMOCODE-DP continuously informs
the process engineer about the current
operating state:
• actual phase current in %
• ON/OFF
• Anti-clockwise, clockwise LEFT/
RIGHT
• Fast, slow
• Slide open, closed, moving
• Warning
• Fault.
Reduction of failures by the
signalling of critical operating
states
The settable current limits inform the
process engineer about critical states
in the system. For example, a current
which is below the lower current limit
setting could mean a broken conveyor
belt for example. The overloading of a
mixing machine for example can be
quickly detected by the display of
‘upper current limit exceeded.’ To avoid
an overload trip of the machine, the
process engineer can take precise
steps to change the working process,
such as reducing the amount of
material in the mixer.
Display of other critical operating
states:
• Current imbalance
• Overload warning/trip
• Thermistor motor protection
warning/trip
• Earth fault warning/trip
• Locked rotor protection
• Warning/trip upper/lower current
limit response.
Reduction of maintenance times
Maintenance intervals can be
increased, as all statistical data relating
to the condition of a particular feeder is
transmitted from the SIMOCODE-DP to
the PLC. SIMOCODE-DP registers the
number of starts and the number of
overload trips, counts the operating
hours and calculates the current in %
of the last trip. All data is stored in a
non-volatile memory in SIMOCODE-DP.
Analogue Current display
For display of analogue current value
through a display device on the panel
door; the SIMOCODE-DP system is
provided with an external current
transformer (range 0.25 A-820 A/1A).
With this it is also possible for the
systemselector to inform about the
actual current flowing in the motor
feeder.
Self-monitoring
The correct function of the
SIMOCODE-DP processor is
permanently monitored. If there is a
fault, SIMOCODE-DP switches the
load to the adjustement, safe state
(OFF, or maintain operating state -
monostable or bistable behavior).
Also testable ‘in action’
This function gives SIMOCODE-DP
additional safety and better monitoring
features.
The operation of SIMOCODE-DP can
be checked during running – without
switching off of the motor. This saves
time and avoids unnecessary
interruptions of the operation.
