SIMOCODE 3UF Motor Management and Control Devices
Expansion with a ground fault measuring module with an
external summation current transformer
Instead of ground fault monitoring using the current measuring
modules or current/voltage measuring modules, it may be
necessary, especially in high-impedance grounded networks, to
implement ground fault monitoring for smaller ground fault
currents using a summation current transformer. A ground fault
module can be used to add an additional input to basic unit 2 for
connection of a summation current transformer (3UL2 20.-.A).
Maximum one ground fault module can be connected to one
basic unit 2.
SIMOCODE pro 3UF7
motor management and control devices
Expansion of analog temperature monitoring with a
temperature module
Independently of the thermistor motor protection of the basic
units, up to 3 analog temperature sensors can be evaluated
using a temperature module.
The temperatures measured here can be completely integrated
in the process, monitored and supplied to a higher-level
automation system. The temperature module can be used, for
example, for analog monitoring of the temperature of the motor
windings or bearings or for monitoring the coolant or gear oil
temperature. Various sensor types are supported (resistance
sensors) for use in solid, liquid or gaseous media:
• PT100/PT1000
• KTY83/KTY84
• NTC
Maximum one temperature module can be connected to one
basic unit 2. The same sensor type must be used in all sensor
measuring circuits.

• Of a current measuring module or current/voltage measuring
module
• Of an operator panel
Note:
A temperature module can only be used with a basic unit 2,
product version E02 and later (from April 2005).
