conductors.
4. Connect the Battery + (positive) wire to the Battery + terminal.
5. Connect the Battery – (negative) wire to a TriStar common – terminal.
6. Connect the Solar + wire (positive) to the Solar + terminal.
(or Load + / Diversion +)
7. Connect the Solar – (negative) wire a TriStar common – terminal.
(or Load – / Diversion –)
NOTE: TriStar negative terminals are common negative.
The CE certification requires that the battery conductors, the battery voltage
sense wires, and the remote temperature sensor shall not be accessible
without the use of a tool and are protected in the battery compartment.
Do not bend the power wires up toward the access cover. If a TS-M meter is
used now or in the future, these large wires can damage the meter assembly
when the access cover is attached to the controller.
Torque each of the four power terminals to 5.65 Nm (50 in-lbs).
Power-Up
• Confirm that the solar (or load) and battery polarities are correct.
• Turn the battery disconnect on first. Observe the LED’s to confirm a
successful start-up. (LED’s blink Green - Yellow - Red in one cycle)
• Note that a battery must be connected to the TriStar to start and operate
the controller. The controller will not operate from a solar input only.
• Turn the solar (or load) disconnect on.
Step 7 - RS-232 Adjustments
The TriStar must be powered from the battery to enable use of the RS-232 /
PC computer connection.
Refer to Section 7.0 for using the RS-232 and
Morningstar’s PC software to change setpoints or confirm the installation settings.
Step 8 - Finish Installation
Inspect for tools and loose wires that may have been left inside the
enclosure.
Check the power conductors to make sure they are located in the lower part
of the wiring compartment and will not interfere with the cover or the
optional meter assembly.
NOTE: If the power conductors are bent upwards and touch the meter assembly
(TS-M option), pressing the cover down on the wires can damage the meter.
REMARQUE : Si les conducteurs d’alimentation sont courbés vers le haut et touche
l’ensemble de mesure (option TS-M), la pression du couvercle sur les câbles peut
endommager l’appareil de mesure.
Carefully place the cover back on the controller and install the 4 cover screws.Closely
observe the system behavior and battery charging for 2 to 4 weeks to confirm the
installation is correct and the system is operating as expected.
3.0 TriStar Operation
The TriStar operation is fully automatic. After the installation is completed,
there are few operator tasks to perform. However, the operator should be
familiar with the basic operation and care of the TriStar as described below.
3.1 Operator’s Tasks
• Use the pushbutton as needed (see 3.2 below)
• Check the LED’s for status and faults (see 3.3 below)
• Support recovery from a fault as required (see 3.4 below)
• Routine inspection and maintenance (see 3.5 below)
If a TriStar digital meter is installed, please refer to the meter manual.
3.2 Pushbutton
In the battery charging mode (both solar and diversion), the following
functions can be enabled with the pushbutton (located on the front cover):
PUSH: Reset from an error or fault.
PUSH: Reset the battery service indication if this has been activated with the
PC software. A new service period will be started, and the flashing LED’s will
stop blinking. If the battery service is performed before the LED’s begin
blinking, the pushbutton must be pushed at the time when the LED’s are
blinking to reset the service interval and stop the blinking.
PUSH AND HOLD 5 SECONDS: Begin battery equalization manually. This
will begin equalization in either the manual or automatic equalization mode.
The equalization will automatically stop per the battery type selected
(see
Section 4.4)
.
PUSH AND HOLD 5 SECONDS: Stop an equalization that is in progress. This
will be effective in either the manual or automatic mode. The equalization will
be terminated.
Note that if two or more TriStars are charging in parallel, the equalization
cycles may start on different days for various reasons (such as one controller
is disconnected and restarted). If this happens, the pushbutton on each
controller can be used to manually start and then stop an equalization,
and this will reset the equalizations to the same schedule.
LOAD & LIGHTING CONTROL
PUSH: Reset from an error or fault.
PUSH AND HOLD 5 SECONDS: After a low voltage disconnect (LVD) of
the load, the pushbutton can be used to reconnect the loads again. The
loads will remain on for 10 minutes, and will then disconnect again. The
pushbutton can be used to override the LVD without limit.
NOTE: The purpose of the LVD is to protect the battery. Repeated
overrides of an LVD can deeply discharge the battery and may damage
the battery.
