10. READING OF MEASUREMENTS AND RECORDED PARAMETERS
Enter the MODE "MEASURE", SELECT the menus "ACT.MEAS"-"MAX VAL"-"LASTTRIP"-
-"TRIP NUM", scroll available information by key "+" or "-" .
10.1 - ACT.MEAS
Actual values as measured during the normal operation.
The values displayed are continuously refreshed.
Display Description
xxXXXxx Date : Day, Month, Year
xx:xx:xx Hour : Hours, Minutes, Seconds
T/Tn xxx % Actual temperature rise displayed as % of the motor full load temperature rise (0 - 999%)
IA xxxxx A True R.M.S. value of the current of phase A displayed as primary Amps. (0 - 99999)
IB xxxxx A
As above, phase B.
IC xxxxx A
As above, phase C.
Io xxxxx A
As above, earth fault current.
Id/m xxx %
Positive sequence component of motor current displayed as % of motor full load
current. (0 - 999)%
Is/m xxx %
Negative sequence component of motor current displayed as % of motor full load current.
(unbalance degree) (0 - 999)%
Uo xxxxx V RMS Voltage displayed as primary volts (0
– 65000)

o xxx °
Phase displacement
h xxxxx Operation hours (0
– 65000)
If no keys is operated in 60 sec, the display comes back to the default indication (T/Tn%)
10.2 - MAX VAL
Highest values recorded during motor run after the starting time (refreshed at each higher value) plus
highest values recorded during the starting time (refreshed at each new starting).
Display Description
T/Tn xxx %

IA xxxxx A Current of phase A measured during run after starting time (0-99999)
IB xxxxx A As above, phase B.
IC xxxxx A As above, phase C.
Io xxxxx A As above, zero sequence current.
Id/m xxx %
Positive sequence component of motor current.
Is/m xxx %
Negative sequence component of motor current
SA xxxxx A
Current of phase A at the starting time.
SB xxxxx A
As above, phase B.
SC xxxxx A
As above, phase C.
So xxxxx A As above, earth fault current.
Sd/m xxx % Positive sequence current component at starting.
Ss/m xxx % Negative sequence current component at starting.
tSt xxxx s Measurement of the Motor Starting time.
SUo xxxx V Zero sequence voltage at starting.
