a valid direction in the map. The current location is
indicated on the display with a column heading, and a bold
descriptor.
4.7.3.2 Adjusting the Meter Display
The display setting options, as shown in Figure 4-7, are
adjustable by using the directional keys to locate and edit a
desired setting or variable.
4.7.4 Using the Meter Display to Program Charging
Set-points, Load Control, Communications, and Advanced
Settings
Refer to the complete meter map insert for metered PS-
MPPTs. From a top level monitoring screens, scroll down to
the Main Menu - "Custom Programming" - screen. Select
the desired category, and edit the variable or settings
as instructed in the meter display. Note that charging
set-points should be entered as if for a 12V system - DIP
switches 2 and 3 settings prompt the controller to multiply
if necessary.
TIP:
Using the meter, Float and EQ stages can
be disabled by setting these voltages to 0V.
The Load Control category includes Normal (load
disconnect) and Lighting programming.
The Advanced
Settings category includes more optional charging, MPPT,
and load control settings.
NOTE:
Without DIPs 4,5,6 ON (up), only COM address
settings options will appear in the meter map. To view and
program custom settings via the meter display, DIPs 4,5,6
must be in the ON (up) position.
4.7.5 Lighting Control / Programming Overview
The ProStar MPPT display has extensive lighting load
programmability.
With DIP switch 1 ON (up), a dusk-dawn lighting program is
enabled, if lighting timing hasn't been programmed in MS-
View or using the meter; with DIP 1, 4, 5, 6 ON, and the unit
programmed, custom timing will be in effect.
With DIP 1 OFF (down), all lighting control functions are
disabled.
Using either MSView or the meter display, four channels
are available for setting timers that can work separately, or
in combination. See Section 4.7.6 - Lighting Programming
Using Meter Display - for more details.
4.7.6 Lighting Programming Using the Meter Display
Lighting programming capabilities are accessible with the
meter via Custom Programming->Load Control->Lighting.
Lighting settings editing is done via on-screen instructions.
• The Summary provides a graphical representation of the
complete lighting configuration
• LVD / LVR can be specified for use when a lighting
program is in operation
• Sunrise and Sunset Threshold settings allow the
adjustment of percentages of the maximum seen solar
array voltage for triggering day and night events
• There are four channels, each having two timers, which
can be used independently, or in combination.
• Events and actions are used as references and controls.
An event is one of eight points in a day e.g. sunrise or
midnight. Each event can be edited to specify a time
offset to trigger an action, which can be, "Do Nothing",
"Lights On", or "Lights Off"
• The combination setting of each channel will specify
whether the actions and events of each timer will function:
not at all (no combination); when both timers' settings
match (AND); for either timers' settings (OR)
4.7.7 Low Temperature Foldback
The ProStar MPPT has a Low Temperature Foldback option
which can be used to protect lithium batteries from being
charged in cold conditions. Custom settings defining the
bounds of charge current reduction due to low battery
temperature can be programming in MSView, or with
the Advanced Custom Settings options with the display
interface.
