Tighten the connector screws to 5 in-lb (0.56 Nm) of
torque.
The maximum length allowed for each battery voltage
sense wire is 98 ft (30m).
Connecting the voltage sense wires to the RTS
terminal will cause an alarm.
NOTE: If the battery input voltage is greater
than 5 Volts different than the Battery Sense,
due to voltage drops or faulty connections, the Battery
Sense input will not be recognized by the ProStar.
A battery voltage sense connection is not required to
operate the ProStar controller, but it is recommended
for best performance.
STEP 3: Remote Temperature Sensor
WARNING: Risk of Fire.
If no Remote Temperature Sensor (RTS) is
connected, use the ProStar within 3m (10 ft) of the
batteries. Internal Temperature Compensation will be
used if the RTS is not connected. Use of the RTS is
strongly recommended.
All charging settings are based on 25°C (77°F). If
the battery temperature varies by 5°C, the charging
setting will change by 0.15 Volts for a 12 Volt battery.
This is a substantial change in the charging of the bat-
tery, and the use of the optional Remote Temperature
Sensor (RTS) is recommended to adjust charging to
the actual battery temperature.
The need for temperature compensation depends
on the temperature variations, battery type, how
the system is used, and other factors. If the battery
appears to be gasing too much or not charging
enough, the RTS can be added at any time after the
system has been installed.
Connect the RTS to the 2-position terminal located
between the battery (-) and chassis ground terminal
lugs (see figure).
The RTS is supplied with 33 ft (10 m) of 22 AWG (0.34
mm2) cable. There is no polarity, so either wire (+ or
-) can be connected to either screw terminal. The RTS
cable may be pulled through conduit along with the
power wires. Tighten the connector screws to 5 in-lb
(0.56 Nm) of torque. Separate installation instructions
are provided inside the RTS bag.
WARNING: Equipment Damage
Never place the temperature sensor inside a
battery cell. Both the RTS and the battery
will be damaged.
CAUTION: The ProStar will use the local
temperature sensor for compensation if the
RTS is not used.
NOTE: The RTS cable may be shortened if
the full length is not needed. Be sure
to reinstall the ferrite choke on the end of the RTS
if a length of cable is removed. This choke ensures
compliance with electromagnetic emissions standards.
