Remark:
(a)
After pushing this button, there is always a validation phase.
(b)
In multi-master inverter units, this function is available on the master unit that has the
control over the system.
Acknowledging of a fault which resulted in a complete inverter system shut down has
two possible consequences:
−
If the fault is permanent (e.g. permanent network under voltage due to phase
loss), it cannot be cleared and the message ‘ACK. FAULT’ will remain on the
display. In this case the cause of the problem has to be identified and removed
before the inverter can be restarted.
−
If the fault is not present anymore when the ‘ACK. FAULT’ command is given, the
menu will change into ‘ESI START’ to indicate that the inverter can be restarted.
Fault analysis can be done by consulting the ‘ESI Monitoring’ menu [/Welcome/ESI
Monitoring]. For more information on the ‘ESI monitoring’ menu, refer to
Section 7.10
If the inverter is set up for remote control operation, the local start/stop command has
no effect.
Disable the digital inputs to override the remote control [/Welcome/Settings/Customer
set./Digital inputs].
7.8 The ‘Measurements’ menu
This menu allows monitoring a variety of variables (e.g. voltage, current …) in a variety
of formats (e.g. RMS-values, spectra, time domain waveforms). Its submenus are
discussed next.
In multi-unit inverters, several parameters are measured by the individual units. In order
to consult measurements from a specific unit, select the unit with the ‘Select Unit’ option
