9 / 114 page SIMOCODE 3UF Motor Management and Control Devices 7/9 Siemens LV 1 T · 2006 SIMOCODE pro 3UF7 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. 3UF7 500-1AA00-0 ground fault module 1 input for connecting a summation current transformer (3UL2 20.-.A) 1 Ready LED 2 system interfaces for connection • To basic unit 2 • Of expansion modules • Of a current measuring module or current/voltage measuring module • Of an operator panel Note: A ground fault module can only be used with a basic unit 2, product version E02 and later (from April 2005). 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. 3UF7 700-1AA00-0 temperature module 3 inputs for connecting up to 3 resistance sensors in 2-wire or 3-wire circuits 1 Ready LED 2 system interfaces for connection • To basic unit 2 • Of expansion modules • 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). |
