Micom P634 - Overload Data Acquisition (Function Group OL_DA); Overload Duration

3.17 Overload Data Acquisition (Function Group OL_DA)
In the event of an overload, the P634 determines the following measured
overload data.
●
Overload duration
●
Measured overload data derived from the measured operating data of the
thermal overload protection functions THRM1 and THRM2; see also
Section 3.25, (p. 3-174).
The following values are determined for each of the two functions:
o
Status of the thermal replica
o
Load current
o
Object temperature
o
Coolant temperature
o
Time remaining before tripping
o
Offset of the thermal replica
The following description refers to the thermal overload protection 1 (THRM1)
function and can be applied similarly to THRM2.
3.17.1 Overload Duration
In the event of an overload, the P634 determines the overload duration. The
overload duration is defined as the time between the start and end of the
OL_RC: Record. in progress signal.
