Notes:
1 If the insulation resistance of the motor is more than 20 MOm, then the value indicator displays code
“
>20M
“.
When
the motor is running (energized motor) the insulation resistance is not defined and the code indicator displays “
---
“(
when
measuring circuit of motor insulation connecting).
2 If ARS is disabled, the indicator displays
“not”.
3 If the time before shutdown by thermal overload protection or waiting time before permit to start-up is not defined
(more than 900 s), then the value indicator displays code
“undef“.
If the protection function is disabled, the indicator
displays
“not”.
4 If the power consumed by the load is more than 999 kW (kVA, kVA
r
), the values of power are displayed with MW
(MVA, MVA
r
).
5
If the temperature value exceeds specified limits, then the indicator displays the alarm code in accordance with table
5.13. If the temperature sensor is disabled by software, then the indicator instead of temperature values displays
“
Off
”.
6
In excess of the energy meter of the value 200 000 000, the counter is reset and the energy metering will start from
zero. Recording the current values of the energy in the non-volatile memory is performed every 15 min.
