4.7 Programming Custom Setpoints
!
CAUTION: This feature should only be used by advanced
users who have very specic charging and/or load
control requirements that are not met using the factory
default charge and load control settings. The factory
default settings will be sufcient for the vast majority of
users.
Custom charging and load setpoints can be programmed into SS-
MPPT non-volatile memory using a PC with Morningstar MSView
software installed and a Meterbus to Serial Adapter (model: MSC).
Refer to the MSView help les for detailed instructions. MSView PC
software is available for free on our website at:
http://www.morningstarcorp.com/
A setup wizard will guide you through the setpoint conguration
process. Refer to MSView help les for more information.
To use custom setpoints, the Settings Switches must be adjusted as
follows:
SWITCH #1 ON (↑) TO USE CUSTOM CHARGING SETPOINTS.
USE THE BATTERY SELECT JUMPER TO SELECT BETWEEN
TWO SETS OF CUSTOM CHARGING SETPOINTS.
SWITCH #2 ON (↑) TO USE CUSTOM LOAD CONTROL
SETPOINTS.
NOTE: Use the custom settings wizard to congure and
program the controller for Lighting load control. This
functionality can only be enabled through custom
settings.
NOTE: Programming custom setpoints will overwrite the
default Gel and AGM battery type values programmed
into custom memory at the factory. Document the new
custom values in this manual for future reference.
