CLASS
Unit for the trip class. Indicates the maximum tripping time in which SIMOCODE must trip at
a current that is 7.2 times the value of the current setting I
according to IEC 60947). If Class 10 is set for SIMOCODE pro, for example, it is ensured
that the (cold) motor will switch off after 10 seconds if a current occurs that is 7.2 times the
current setting. The trip class can be set to eight different settings ranging from Class 5 to
Class 40.
Class 1 master
Active station on PROFIBUS DP. It is characteristically used for cyclic data exchange with
other stations. Typical Class 1 masters include PLCs with a PROFIBUS DP connection.
Class 2 master
Optional station on PROFIBUS DP. Typical class 2 masters include:
● PC/PG with SIMOCODE ES (TIA Portal)
● PDM (PCS7)
● PC with "SIMARIS manager" software (power management).
Connecting cable
Connecting cables are necessary for connecting the individual basic units with their current
measuring modules and, if required, with their expansion modules or operator panels. They
are available in various versions and lengths (ribbon cable 0.025 m, 0.1 m, 0.15 m, 0.3 m,
0.5 m; round cable 0.5 m, 1.0 m, 2.5 m).
Notice
Maximum length of connecting cables:
The total length of all cables must not exceed 3 m on either of the system interfaces of the
basic unit!
Contactor
Electromagnetically operated low-voltage switch with only one position of rest; it cannot be
manually operated. Contactors can energize, carry, and deenergize currents in a circuit
under normal operating conditions, including operational overload. The contact system
consists of main and auxiliary contacts (NC, NO). Depending on the size of the contactor,
the main contacts can switch several hundred amps while the auxiliary contacts are only
rated for control currents of a few amps.
