The response of SIMOCODE pro on reaching a pre-warning
level or trip level can be freely parameterized and delayed.
Voltage measuring is carried out using current/voltage
measuring modules.
The basic unit has several protection mechanisms for current-
dependent motor protection:
• Overload protection
• Unbalance protection
• Stalled rotor protection
• Thermistor protection.
SIMOCODE pro can monitor the stop times of a motor in
order to avoid plant down times due to failed motors caused
by either running too long (wearing out) or being stopped for
too long.
The motor operating hours monitoring function enables the
operating hours (service life) of a motor to be recorded so
that motor maintenance prompts can be generated in good
time as applicable.
SIMOCODE pro can monitor the operating hours and stop
times of a motor and restrict the number of start-ups in a
defined time frame in order to avoid plant downtimes due to
failed motors caused by running or being stopped for too
long.
The "Operational Protection OFF (OPO)" function block puts
the positioner into a safe position and switches the motor off.
The operator panel controls the motor feeder from the
switchgear cabinet. It contains all the status LEDs which are
on the basic units, the "TEST/RESET" button and the external
system interface.
It can be used with both the SIMOCODE pro C device series
and the SIMOCODE pro V device series.
The operator panel with display can be used as an alternative
to the standard operator panel (OP).
It displays the current measured values, operating and
