Display Settings - Used to set the characteristics of the display.
1. Light: setting of the mode and adjustment of the brightness of the display
• Mode:
ON: Light always on.
OFF: Light always off.
• Auto: Automatic light control. The light comes on whenever a button is pressed and stays on
for 30 sec, after which it gradually goes out.
• Intensity: adjustment of display brightness (scale from 0 to 9).
2. Contrast: adjustment of display contrast (scale from 0 to 9).
3. Buzzer: button sound setting
ON: the sound of the buttons is activated.
OFF: the sound of the buttons is deactivated.
3. Power Graph: Time range: 8 H, 16 H, 24 H
Service - This section of the menu is reserved for installers and it is necessary to have a dedicated
password. See Troubleshooting, section 5, for instructions to obtain the service level password.
The Service menu can be used to adjust the Voltage and Frequency Trip Limit and Trip Time
Parameters according to the grid requirements of the installation locale. This inverter has been
factory programmed to automatically disconnect from the utility distribution system in compliance
with UL 1741 and IEEE1547 specications. Default voltage and frequency trip limit and trip time
settings to comply with these standards are shown in the table below.
The table lists the default and adjustable parameters available in the Service submenu. Using
the UP and DOWN keys on the inverter display panel, scroll to select the values for modication.
WARNING!
ABB cannot be held responsible for any negative effects resulting from modications
of inverter set points. The set points in the table below should only be changed with the written
permission of the local utility.
Changes to the voltage and frequency trip limit and trip time parameters MUST be done by a qualied
contractor or authorized personnel. Improper values entered could cause bodily harm and cause the
inverter to shut down.
