Earth-fault module (EM)
For networks grounded with a higher impedance it may be necessary to set
up earth-fault monitoring for smaller earth-fault currents using a 3UL22
summation current transformer, instead of carrying out earth-fault
monitoring via a current measuring module or current/voltage measuring
module. Rated fault currents of 0.3 A, 0.5 A, and 1 A can be evaluated with
the summation current transformer.
In addition to the internal earth-fault monitoring supported by both device
series, SIMOCODE pro V can thus be expanded by a more precise,
additional external earth-fault monitoring system.
The earth-fault module adds an additional input for connecting a summation
current transformer to basic unit 2.
• 1 earth-fault module connectable to BU2.
Note
The use of an earth-fault module requires basic unit 2, above at least version
*E02* (from 04/2005).
Temperature module (TM)
The temperature module allows expansion of the SIMOCODE pro V device
series with an analog temperature monitoring system. In addition to
monitoring thermistors of the basic units, up to 3 analog sensor measuring
circuits (in two or three-wire systems) can be connected, the temperatures
in the 3 sensor measuring circuits can be measured, and the highest
temperature in all sensor measuring circuits can be determined. The
measured temperatures can be fully integrated into the process, and they
can be further monitored and also made available for a higher- level
automation system via PROFIBUS.
This makes it possible, for example, to implement analog temperature
monitoring of the motor windings, bearings, the coolant temperature and
the gear oil temperature.
SIMOCODE pro V supports different sensor types (NTC,
KTY83/84, Pt100/Pt1000) for use in hard, fluid or gaseous media.
Notice
The same sensor type must be used in all sensor measuring circuits.
• 1 temperature module connectable to BU2
• 3 sensor measuring circuits in 2 or 3-wire systems
Note
The use of an analog module requires basic unit 2, above at least version
*E02* (from 04/2005).
