energized inputs.
In default configuration, RE2 serves as an impulse common trip contact
this contact to operate e.g. opening or UV coil of circuit breakers.
Remaining 3 relay outputs serve for signaling of any sensed failure.
The arrangement of RE1 to 4 outputs in default configuration corresponds to the functionality of the
previous NPU-FUV unit outputs.
3.3.7 Binary switches connection
MainsPro G99TT provides 4 galvanically isolated binary switches with configurable functionality. These
inputs allow connection of any voltage free contact between the common terminal BIC and the appropriate
functional contact (BI1 – BI4).
Particular functions (Ext1, Ext2, Fault Reset, Alternative settings, Disable, CB Feedback) are freely
assignable by setpoint in
Note: It is not possible to assign the same function to two different Binary Inputs.
For full description see Library of Binary switches on page 63.
3.4 Measurement range
MainsPro G99TT allows using multiple voltage ranges on the measurement inputs with unchanged
measurement accuracy. The following ranges are applicable:
230 V - this range applies in case of "star" connection of the 3-phase system using nominal 230V phase to
neutral. It may be also used for single-phase applications 230V phase to neutral. Overshoot by 30% up to
290V is possible for this measurement range. For this case, set the setpoint
MainsPro G99TT will adjust automatically the measurement method, to assure the defined accuracy for
the measured voltage 230 V.
400 V - this range applies in case of "delta" connection of the 3-phase system using nominal 400V phase
to phase. Overshoot by 30% up to 520V is possible for this measurement range. For this case, set the
setpoint
Uin (page 54)
to assure the defined accuracy for the measured voltage 400 V.
120 V - this range is applicable in countries using 120 V nominal voltage phase to neutral. Another
application is for the high-voltage and other applications, using voltage transformers from rated voltage to
100 V. The guaranteed accuracy applies to both ranges 100 and 120 V. Overshoot by 30% up to 156V is
possible for this measurement range. For this case, set the setpoint
3.5 Wiring examples
This chapter provides examples of possible wiring of MainsPro G99TTwhich can be used as a preparation
concept of wiring scheme.
