3UF5 SIMOCODE-DP System Motor Protection and Control Device

If the automatic level switches to
manual operation, or if local control is
activated by means of a local manual/
automatic key switch, the bus control
commands are ignored and the feeder
can now be exclusively controlled via
the operating module or using the local
control station.
Reduction of failure times by
autonomous operation
In case of system failures on the
communication system, SIMOCODE-
DP automatically switches to manual
mode.
When this occurs, the load is either
switched OFF or the operating state is
maintained. Further control is possible
using the manual mode.
Downtimes in case of failures in the
automation and communication level
are considerably reduced: The process
can still be safely continued locally due
to the autonomous structure of the
SIMOCODE-DP.
The process can be resumed however
surely by the self-sufficient structure of
the system SIMOCODE-DP locally.
It means self-sufficient that all
protective relay for motor and control
functions are processed independently
of the automation level in the
SIMOCODE-DP.
Flexibility due to decentralised
signal logic-, delays- and
conditioning
The great flexibility of the SIMOCODE-
DP system is especially characterised
by the integrated:
• 3 truth tables
(3 inputs with 1 output each)
• 1 truth table
(5 inputs with 2 outputs)
• 2 timers
(0.5 s...60 min; output behavior:
ON delay, OFF delay, fleeting
NO contact)
• 2 counters
(0...65535)
• 4 elements of signal processing
– Inverted level without memory
– Rising edge with memory
– Falling edge with memory
• Signal conditioning
– 3 flashing modules
– 3 flickering modules.
• 2 elements of non-resetting
onvoltage failure
The inputs and outputs of the system
can be assigned to predefined control
functions as well as to the truth tables,
timers and counters. Thus, a flexible
use of the predefined control functions
is possible.
The make/break contact behavior of
the outputs is set by the signal
processing modules.
Selective start of the system
After a mains failure, the motor feeders
can be restarted using time-grading.
This makes a fast and selective start of
the system possible.
