motor management and control devices
Monitoring additional process variables over analog inputs
(0/4 ... 20 mA)1)2)
• The analog module enables SIMOCODE pro to measure
additional process variables and monitor them. A pump can,
for example, be protected against dry running in this manner
with level monitoring or the degree of pollution of a filter can
be measured using a differential pressure transducer. When a
specified level is undershot, the pump can be deactivated
and when a specified differential pressure is overshot, the filter
can be cleaned.
• SIMOCODE pro supports two-step monitoring of the corre-
sponding process variable for freely selectable upper and
lower current limit values. The response of SIMOCODE pro
can be freely configured and delayed if it reaches an alarm or
tripping threshold.
Phase sequence detection3)
• By detecting the phase sequence, SIMOCODE pro is able to
make a statement about the direction of rotation of a motor. If
the direction is incorrect, this can be reported or it can result
in immediate shutdown of the affected motor.
Monitoring of operating hours, downtime and number of starts
• In order to prevent plant downtime caused by motor failure
due to excessive motor operating times (wear) or excessive
motor downtimes, SIMOCODE pro can monitor the operating
hours and downtime of a motor. When an adjustable limit value
is violated, a message or alarm can be generated which can
indicate that the corresponding motor must be serviced or
replaced. After the motor has been replaced, the operating
hours and downtimes can be reset, for example.
• To avoid excessive thermal loads and early wear of the motor,
it is possible to limit the number of motor startups for a
specifiable period. Alarms can indicate that only a small
number of possible starts remain.
Flexible motor control implemented with software
Many typical motor control functions have been predefined in
SIMOCODE pro and are available for use:
• Direct-on-line and reversing starters
• Wye-delta starters (also with direction reversal)1)
• Two speeds, motors with separate windings (pole-changing
switch); also with direction reversal1)
• Two speeds, motors with separate Dahlander windings
(also with direction reversal)1)
• Slide control1)
• Solenoid valve actuation1)
• Actuation of a circuit-breaker (MCCB)
• Actuation of a 3RW soft starter also with direction reversal1)
These control programs already include all the software
interlocks and logic operations required for operation of the
required motor functions.
It is also monitored whether the current checkback of the motor
feeder corresponds with the control command. If not,
SIMOCODE pro opens the motor contactor and generates an
alarm indication.
Depending on the application, motor control can be switched
over or carried out simultaneously from several control stations,
e.g.:
• From the I&C system through PROFIBUS DP
• From a PC/PG through PROFIBUS DP
• From the control cabinet door through the operator panel
• From a PC/PG on the system interface through
SIMOCODE pro
• From a local control station on the motor. In this case, the
buttons, switches and indicator lights are connected to the
inputs and outputs of SIMOCODE pro.
Regardless of whether a control command is sent to SIMOCODE
pro via PROFIBUS DP using the operator module or via the
buttons connected to the binary SIMOCODE pro inputs,
SIMOCODE pro can execute these control commands
simultaneously or in accordance with the enabled commands
defined during configuration.
These predefined control functions can also be flexibly adapted
to each customized configuration of a motor feeder by means of
freely configurable logic modules (truth tables, counters, timers,
edge evaluation etc.).
In addition, special standard functions are stored in
SIMOCODE pro which can also be used to extend the protection
and control functions, e.g.:
• Power failure monitoring1) for automatic, time-staggered
restart of motors following a network failure e.g. with the help
of a separate voltage relay (voltage controller).
• Fault signaling modules for external faults with or without
manual or automatic acknowledgement for generating internal
messages or for tripping SIMOCODE pro in response to freely
definable events (e.g. overspeed monitor has been
activated). Designations/names can also be assigned to the
external faults which are stored in the device and which are
therefore also available to the I&C system.
• Emergency start function and reset of the thermal memory of
SIMOCODE pro after tripping, i.e. immediate restart is
possible (important, for example, for pumps used to
extinguish fires).
• Test function for the load feeder circuit when the main control
switch is open to test the control circuit while the main circuit
is de-energized.
Detailed operational, service and diagnostics data
SIMOCODE pro provides a variety of operating, service and
diagnostic data, such as:
Operating data
• The switching state of the motor (On, Off, clockwise, counter-
clockwise, fast, slow) is derived from the current flow in the
main circuit, so checkbacks are not required through auxiliary
contacts from circuit-breakers and contactors
• Current in phase 1, 2, 3 and maximum current in % of the set
current
• Voltage in phases 1, 2, 3 in V3)
• Active power in W3)
• Apparent power in VA3)
• Power factor in %3)
• Phase unbalance in %
• Phase sequence3)
• Temperature in sensor circuits 1, 2, 3 and maximum
temperature in °C1)4)
• Current values of the analog signals1)2)
• Time until tripping in sec.
• Temperature rise for motor model in %
• Remaining cooling time of the motor in sec. etc.
Service data
• Motor operating hours (can be reset)
• Motor stop times (can be reset)
• Number of motor starts (can be reset)
• Number of remaining permissible motor starts
• Number of overload trips (can be reset)
• Internal comments, stored in the device for each feeder,
e.g. notes for maintenance events etc.
