Battery Temperature Sensor (BCA Only)
This unit is supplied with one battery temperature sensor. The sensor communicates the
temperature of the battery to the battery charger and is necessary for the charger’s voltage
temperature compensation, battery over temperature shutdown and equalize cycle functions.
BATTERY TEMPERATURE SENSOR CONNECTION
This unit is equipped with an Amphenol MIL-Spec PT02A8-4S connector to connect to up to
two Analytic Systems waterproof battery temperature sensors. This connection’s pinout can
be found on the unit label.
TO INSTALL THE SENSOR AT THE BATTERY:
• Slide the sensor ush between the side of the battery and wall of the battery platform.
• Place the battery on top of the sensor to hold it in place.
• Apply a small amount of silicone RTV sealant to the sensor and stick it to the top of the
battery.
There are multiple ways to install the sensor at the battery. Regardless of which method you
use, the sensor must be rmly secured and should not lose physical contact with the battery at
any point in the charging cycle.
VOLTAGE TEMPERATURE COMPENSATION
Heat is a normal by-product of the charging cycle. However, excessive heat can cause
overcharging, damaging the battery. With a battery temperature sensor installed, the battery
charger will automatically reduce the charging voltage to compensate for rising temperature.
The ambient battery temperature is pre-set to 77°F (25°C). For each degree above 77°F (25°C),
the charger will reduce the charging voltage by a small amount. See Specications for more
information regarding, the default temperature compensation coefcient of your unit. You can
change the voltage temperature compensation coefcient and set its operating thresholds
using Analytic Systems’ free-to-download software PowerWizard.
