CHARGE CURRENT increases the amount of charge current the rectifier/charge supplies
the battery bank. There are three possible options (LO/ME/HI). The factory will set the
system at the optimal charge level for the battery bank provided. To change the level of
charge select the CHARGE CURRENT option then select the level of charge via the UP
(↑) and DOWN (↓) keys. Once the level of charge has been selected confirm with the
ENTER (↵) key.
The CHARGE CURRENT can be roughly selected by the simple rule listed below:
CHARGE CURRENT SETTING
10 – 30 min battery back-up LOW
30 min – 1 hour battery back-up MEDIUM
> 1 hour battery back-up HIGH
Selecting the ‘EXIT’ option (blinking instead of pointed by cursor) will return you to MENU
5.
