1 — OVERVIEW
Fig. 1 Curtis Acuity
®
Battery Monitoring System.
The system mounts directly to an industrial vehicle lead acid battery and
measures, records, and transmits battery performance data throughout the life
of the battery.
The Curtis Acuity is ideal for use in electric vehicles with applications
such as material handling, airport ground support, floor cleaning, light-on-road,
golf/utility, and aerial work platforms. Features include:
3Highly accurate state-of-charge calculation that uses a weighted
average of ampere-hour counting and voltage under load
measurements.
3Witness data that demonstrates the battery has been operated
within the conditions of its warranty.
3Since Acuity is permanently attached to the battery, information
is collected consistently and accurately over the lifetime of the
battery, no matter how many times the battery is moved.
3Data can used to optimize productivity of a battery fleet/vehicle.
3CANbus allows simple system integration.
3Installation is simple and non-invasive, with no need for special
hardware and no cutting of cables or drilling into the battery.
3Integral real-time-clock allows date and time stamping of
significant events related to the battery or any vehicle component
of the CANbus.
3CANbus isolation eliminates ground loops that can cause
component damage as well as data errors due to differences in
ground potentials among the nodes on the CANbus.

3By measuring, recording, and communicating battery current,
voltage, temperature, and use-time, Acuity can compensate
for the effects of variations in load, duty cycle, and operating
temperature of any given application.
3Calculates the percent of rated capacity remaining in the battery
as an indication of remaining battery life.
3Curtis Acu-Set software, when installed on a computer connected
to an Acuity via a CAN-to-USB dongle, allows Acuity to be
configured to match the specific battery to which it is mounted.
3Historical data can be uploaded to a PC.
3Instantaneous battery performance data can be viewed on a PC
(Power Prover mode).
CANopen Convenience
The Acuity is CANopen compliant, responding to the standard NMT, PDO,
and SDO communications as well as the DS301-required identity and stan-
dard objects. The Curtis CANopen extensions allow additional features, such
as OEM and User default configurations.
The Acuity will receive a single SDO and respond with a single SDO.
These SDOs are fixed, simplifying the interface to a VCL-enabled device. All
programmable parameters and viewable values within the Acuity are accessible
via standard SDO transfer.
Battery information is displayed in real time on the Curtis enGage
®VII
or any other CAN-based display.
Familiarity with your Curtis Acuity system will help you install and operate it
properly. We encourage you to read this manual carefully. If you have questions,
please contact your local Curtis office.

Connecting B+, B–, and the temperature sensor
The Acuity’s B+, B–, and temperature sensor connections are made via 5/16"ring
terminals. Simply place the ring terminal over the battery stud/terminal and
then replace the washer and nut.
Installing the current sensor
The current sensor is polarity sensitive and must be properly oriented for the
Acuity to work correctly.

CURRENT
SENSOR
Either B+ or B– can be selected to pass through the current sensor, de-
pending on the battery configuration and location of the current sensor.
Pass the end of the battery cable through the opening of the current
sensor, making sure that the marking on the current sensor is pointing in the
correct direction.
Insert a tie wrap into each of the slots in the current sensor and pull the
battery cable tight against the side of the current sensor in which the slots are
located.
Mounting the Acuity module
Locate the Acuity module on the battery in such a way as to avoid damage to
the Acuity through normal battery/vehicle use. Use acid-resistant tie wraps to
secure the Acuity to the battery using the intercell connectors and the ribs that
are molded into the Acuity module; see Figure 3.

2 — INSTALLATION & WIRING
CAN connections
The CAN connector is either a 2-pin Deutsch or two bullet-style connectors.
Note that the Deutsch connector is not acid resistant, and therefore if used
should be located at least one meter away from the battery.
The termination resistors on a cable should match the nominal impedance
of the cable. ISO 11898 requires a cable with a nominal impedance of 120Ω;
therefore, you should use 120Ωresistors for termination. If you place multiple
devices along the cable, only devices at the ends of the cable need termination.
You can specify whether the Acuity will include the 120Ωtermination resistor
(see Specifications, page 28).

3 — ACU-SET SOFTWARE
3ACU-SET SOFTWARE
Acu-Set software is license-based and will only run on the PC on which it is
originally installed. After the software is purchased, instructions will be emailed
from Curtis to define the download and activation procedure. Acu-Set is not
transferrable. If it is required that Acu-Set be loaded on a different computer,
a new license is required.
Connecting the Acuity to the computer
Make sure the Acuity is powered on before making the connections, then
follow these steps.
• Using the Peak USB-to-CAN dongle (Curtis p/n 17697USBCANI-01) and
mating harness (Curtis p/n 17668357):
Connect bullet connectors on Acuity to mating bullet con-
nectors on harness
Connect sub-D connector on harness to mating sub-D
connector on Peak dongle.
• Install the dongle USB driver by inserting the CD into the computer and
following the instructions.
• Copy the PCANBasic.dll file for the Peak dongle from the dongle CD to
the folder where the Acu-Set software is executable (the folder where the .exe
file is located). The process is the same for the other brands of dongle: i.e., the
driver needs to be downloaded and the .dll file must be in the same folder as
the Acu-Set executable.
• Plug the dongle’s USB connector into the USB slot on the computer.
• From within the folder in which the Acu-Set files were saved, double-click
on the Acu-Set .exe file.

3 — ACU-SET SOFTWARE
Establishing communication between Acuity and computer
Follow these steps to establish communication.
• Click on the COMM tab at the top of the Acu-Set screen.
• From the drop-down menu, select your CAN dongle:
Kvaser BlackBird WiFi
SYS TEC USB-CAN
Peak USB-CAN [default selection]
CANBlue II.
Note: If you are using the CANBlue Bluetooth dongle, select CANBlue
# Comm Port in the field below the dongle selection field.
• When the default Peak dongle is chosen and the baud rate and node ID match
the Acuity, Acu-Set will automatically display the Power Prover tab. If this did
not happen, review the Baud Rate and CAN Node ID settings.
The default baud rate is 125 kbps. If it is necessary to change this setting
to match your system, select the proper baud rate from the drop down menu:
100 kbps
125 kbps [default setting]
250 kbps
500 kbps
1000 kbps.
The default Node ID is 42. If it is necessary to change this value, enter
a value between 1 and 127 that is not already in use. The Node ID List shows
the Node IDs of all devices that are transmitting in that network at the selected
baud rate.
