Where applicable the settings for individual units in an inverter system can be reviewed
by selecting the appropriate unit.
Note that the settings of the above-mentioned parameters can only be changed at the

7.9.4.1 Setting up the ‘standby’ function
For setting up the ‘standby’ function, go to
[/Welcome/Settings/Installation set./Start-Stop set.]
In multi-master units these functions need to be set up in each master-unit in order to
obtain full redundancy.
The ‘standby’ function when enabled puts the inverter in standby, a preset time after the
load requirement disappears. In this condition, the IGBTs stop switching while the main
contactor remains closed (inverter remains connected to the network). This way the
inverter losses become virtually zero. The inverter will resume normal operation a preset
time after the load requirement comes back. The standby function is particularly
interesting for applications where the load is present for a long time and subsequently
switches off for another long time.
In order to set-up the standby function, five parameters have to be defined:
−
‘Stdby status’:
When enabled, the ‘standby’ function is activated.
When disabled, the ‘standby’ function is deactivated.
