Installation Manual

Temperature sensors should be mounted directly to side of a cell casing below
the electrolyte level to determine accurate cell temperature. On dual-container
models, remove the cover and mount the sensor directly to cell. See Figure 7.
When using chargers that do not feature temperature compensation, voltage
settings should be monitored and adjusted based on actual cell temperature.
TEMPERATURE COMPENSATION & SENSOR INSTALLATION
For additional data and safety, many systems use a temperature sensor mounted
to the battery to measure cell temperature to adjust charge voltage accordingly.
The probe should be installed on the side of one of the batteries or cells located
in the center of the bank. If included with charge equipment, a temperature sensor
must be properly mounted and connected to ensure the appropriate charge
voltage. Failure to use the provided sensor may cause damage due to over/
undercharge which is not covered under Rolls Battery manufacturer warranty.
As a safety precaution, this sensor may trigger a programmed safety charge cut-off
as the battery bank should not exceed an operating temperature of 52ºC (125ºF).
Temperature sensor should not be mounted to the battery terminals
or top of the battery case.
Series 4000, 4500, AGM & GEL models – temperature sensor should be
mounted on the side of the battery case in the middle of the bank. To ensure
an accurate reading of cell temperature the sensor must be mounted below the
liquid level on flooded models. (half way down the side and/or 4-5” from the top
of the case is generally sufficient) For AGM & GEL models, the sensor should
be mounted half way down the side of the battery case.
Series 5000 – If the battery has a modular, dual-container construction the case
cover must be removed to mount the sensor directly to the side of an internal
cell. To remove the cover you must first disconnect the terminal connections.
Most covers snap-on or may have small plastic pins along the edge which may
be easily removed with a screwdriver. Run the connecting cable between the
case and cover, being careful not to pinch of damage the wire. You will notice
a black silicone has been applied around each terminal. This may be removed
and replaced with a standard automotive silicone after reinstalling the cover.
