Once a threshold has been set the ESI-Manager starts recording the maximum (or
minimum) value automatically as well as the total duration until a reset is performed.

logging function
The parameters that can be used with the logging function are voltages (Vrms, THDV),
currents (Irms), Power (P, Q, S), frequency and temperature (T IGBT and Tcontrol) along
with temperatures recorded by the probes (max. 8 probes possible). All information
about temperature are specific to the probe connected to the ESI-Manager where the
probe is connected. Refer to
for an explanation of the parameters. For the
frequency, minimum values and duration below a threshold can also be recorded.
The recorded information may be cleared by selecting and validating the ‘Reset’ item.
If the hardware lock is engaged, the logging function cannot be started nor reset
(Cf.
Section 7.6
shows an example in which the network voltage between L1 and L2 is
monitored. The nominal network voltage is assumed to be 400 V. The threshold was
initially set at 1000 V and is changed to 420 V.
