Measurements – Present status - Statistics
Only read data is found in these 3 items. Therefore, there are no parameter setting possibilities in
them.
Contents of 3 items, level 1: Measurements – Present Status – Statistics.
Measurements :
Currents
: current measur thermal state.
Voltages
: voltage measu frequency.
Powers/energies
: power measur power energies.
Temperatures
: temperature measurements, channels 1, 2, and 3 (IMM 8002).
Present status :
Start status
: time and current of last start + information related to function [5] + advised
heating time constant.
Digital input status
: state of the 6 digital inputs.
Relay output status
: state of relays P, T, A, or B.
Start inhibit status
: possible inhibition by thermal state, number of starts, or voltage range.
Statistics :
Maintenance
: number of start trips +’ERST operating hours.
Last 5 trips.
Last 5 alarms.
Last 5 starts.
4.2.3.
Protection parameters, reference variables
All the protection parameters are duplicated (tables 1 and 2), and the rated values are single.
Figure 1 at the end of the first line indicates that we are in table 1, and figure 2 table 2.
