10.3 Direct Access - Direct Access to the Parameters
The "600# Direct Access" menu gives you direct access to the selected parameter using the
parameter name or number.
Via the Select Name sub-menu, you have direct access to the following functions:
•GnManStr: manual starting of the generator (see Section 14.1.4 "Manual Generator
Operation", page 121)
• ManChrgSel: manual starting of equalization charge (see Section 13.4.3 "Equalization
Charge", page 112)
Via the Select Number menu, you have direct access to every parameter by entering the parameter
number.
10.4 Compact Meters
The "150# Compact Meters" menu is intended primarily to help the installer commission the device.
The display gives you information at a glance on the following areas:
•Battery 1
•Battery 2
• Inverter (AC values)
•InvTot
• Grid/generator (external)
•ExtTot
•Inverter status
Example
Using the menu 600#, you can select the "222.01 BatChrgCurMax" parameter, for example,
to set the maximum battery charging current.
The direct access must be entered as a five-digit number, for example, 22201. Here, the first
three digits describe the menu number and the last two describe the parameter number.
Exit the menu level after the parameter has been set.
Selecting the area
You can select the different displays of the compact meters using the up/down arrow buttons.
Here, you can also use the "Wrap around" function.
The displays are always shown from the upper left to the lower right.
