Select one of the 7 standard battery charging algorithms, or select the
“custom” DIP switch for special custom settings using the PC software.
Refer to Section 9.0 of this manual for battery charging information. The 7
standard charging algorithms above are described in Section 4.2 - Standard
Battery Charging Programs.

In the Auto Equalization mode (switch #7 On), battery equalization will
automatically start and stop according to the battery program selected by
the DIP switches 4,5,6 above.
See Section 4.0 for detailed information about
each standard battery algorithm and the equalization.
In the Manual Equalization mode (switch #7 Off), equalization will occur only
when manually started with the pushbutton. Automatic starting of equalization
is disabled. The equalization will automatically stop per the battery algorithm
selected.
In both cases (auto and manual mode), the pushbutton can be used to start
and stop battery equalization.

The PWM battery charging algorithm is standard for all Morningstar charge
controllers. However, in cases where the PWM regulation causes noise inter ference
with loads (e.g. some types of telecom equipment or radios), the TriStar can be
converted to an On-Off method of solar charge regulation.
It should be noted that the On-Off solar charge regulation is much less effective
than PWM. Any noise problem should be suppressed in other ways, and only if no
other solution is possible should the TriStar be changed to an On-Off charger.
LOAD & LIGHTING CONTROL
DIP switch settings are in Appendix 1.
DIVERSION CHARGE CONTROL
DIP switch settings are in Appendix 2.
NOTE: Confirm all dip-switch settings before going to the next installation steps.
REMARQUE : Confirmez les réglages de tous les commutateurs dip avant de passer
aux étapes suivantes d’installation.
Step 4 - Remote Temperature Sensor (RTS)
F or solar battery charging and diversion load control, a remote temperature sensor
(RTS) is recommended for effective temperature compensated charging. This remote
temperature probe should not be installed for dc load control.
The optional
Morningstar RTS is connected to the 2-position terminal located between the
pushbutton and the LED’s.

Figure 2.3 - Step 4 RTS Connection
The RTS is supplied with 10 meters (33 ft) of 0.34 mm
2
(22 AWG) cable.
There is no polarity, so either wire (+ or –) can be connected to either screw
terminal. The RTS cable may be pulled through the conduit with the power wires.
Tighten the connector screws with 0.56 Nm (5 in-lb) of torque.
Refer to the installation instructions provided with the RTS.
NOTE: Never place the temperature sensor inside a battery cell. Both the RTS and
the battery will be damaged.
REMARQUE : Ne placez jamais la sonde de température dans un élément de
batterie. Le RTS et la batterie seraient endommagés.
Step 5 - Battery Voltage Sense Connection
A battery voltage sense connection is not required to operate your TriStar
controller, but it is recommended for best performance in all charging and load
control modes. The battery voltage sense wires carry almost no current, so the
