Installation
If a TriStar meter is installed, check the “TriStar Settings” to confirm the Voltage Sense and the
RTS (if installed) are both present and detected by the controller. MSView
TM
PC software can
also be used to confirm the voltage sense is working correctly.
Step 9 - Adjust Settings Switches
Switch 1: Future Use

Allows for nominal charging voltages of 24, 36, or 60V. Battery compatibility must be verified.
Switches 4, 5, & 6: Battery Charging Settings
It is important to select the battery type that matches the system battery to ensure proper charg-
ing and long battery life. Refer to the specifications provided by the battery manufacturer and
choose a setting that best fits the recommended charging profile.

All settings are for 48 volt nominal systems. Descriptions of battery type and stages are provided
below. See section 4.2 for full details.
Battery Type - The most common battery type associated with the specified charging settings.
Absorption Stage - This stage limits input current so that the Absorption voltage is maintained.
As the battery becomes more charged, the charging current continues to taper down until the
battery is fully charged.
Float Stage - When the battery is fully charged, the charging voltage will be reduced to the Float
voltage setting.
Equalize Stage - During an equalization cycle, the charging voltage will be held constant at the
specified voltage setting.
Equalize Interval - The number of days between equalization charges when the controller is
configured for automatic equalizations (settings switch 7).
Switch 7: Battery Equalization
Choose between manual and automatic battery equalization charging. In the manual
equalization setting, an equalization will only occur when manually started with the pushbutton or
when requested from the equalize menu on the TriStar meter. Automatic equalization will occur
according to the battery program specified by settings switches 4, 5, & 6 in the previous step.
In both settings (auto and manual), the push-button can be used to start and stop battery
equalization. If the selected battery charging setting does not have an equalization stage, an
equalization will never occur, even if requested manually.

Switch 8: Ethernet Security
The Ethernet Security switch enables or disables configuration of the TS-MPPT-600V-TR set-
tings through the Ethernet connection. When switch 8 is set to
disabled
, write commands to the
TS-MPPT-600V-TR custom memory are not allowed through the Ethernet connection. This safety
feature will prevent unintended changes to custom settings, but it is not a substitute for proper
network security.

NOTE:
Adjustment of network settings and custom set-points is always enabled via the RS-232 and EIA-
485 connections. The Ethernet Security switch only enables/disables remote configuration via
TCP/IP.
