Library of setpoints
MainsPro provides the possibility of dual setting of the protection functions setpoints. This setting may
be used in case that the installation is running in exceptional conditions with different requirements for
protections setting. Some groups of setpoints have their alternative setpoints identified by the same
name, but with latter “A.” at the beginning (e.g. V<>, A.V<> etc.). By activating the binary switch Alt
settings, the unit is immediately switched to the setting, done in the “A.xx” group. See more in the
chapter Library of binary switches.
Basic
Uin
Selection of the measurement range to adjust the HW for maximum accuracy.
230/400V the unit measures 230 VAC phase-ground or 400V phase-phase with max over-range
130% (300/520 VAC)
120V the unit measures 120 VAC phase-ground or on the secondary winding of the VT with
max over-range 130% (156 VAC)
Default setting: 230/400V
System
Selection of single phase or three-phase application. In case of single phase setting, the voltage on
last two phases and voltage asymmetry are not measured.
3ph the unit measures 3-phase system
1ph the unit measures single-phase system
Default setting: 3ph
DispT [min]
Setting of display backlight timeout since the last button activity.
Range: 1..60 min
0 min = OFF, display is set to permanent backlight
Default setting: 0 min
Auto FR
Enabled or disables the functionality of the automatic fault reset by internal timer.
ENABLED the functionality is enabled
DISABLED the functionality is disabled
Default setting: ENABLED
Auto FR Del [s]
Automatic fault reset delay. The timer starts to count in the moment when TRIP is detected, but the
fault conditions are cleared. After the Auto FR del time, the Fault reset is done automatically to allow
automatic reconnection.
Range: 0..6000 s
Default setting: 0 s
Start Trip
Start of the unit into the TRIP state to allow automatic delayed return to mains in case that the mains
is completely lost and MainsPro unit is powered from the same mains voltage.
ENABLED after power-up, the unit goes immediately into the TRIP state and only after successful
fault reset its outputs are set to the fault-free state
