1- OVERVIEW
OVERVIEW
Curtis 1310 provides unprecedented flexibility and ease of use in a full featured programmable
Vehicle System Controller. Containing FLASH memory, a powerful microcontroller and a wide
range of inputs and outputs, the 1310 can be custom programmed to provide application specific
vehicle functions, from the most complex to the most unique. Custom software for the 1310 is
developed with the powerful yet easy to learn Curtis VCL (Vehicle Control Language).
The Curtis 1310 Vehicle System Controller integrates and and expands systems through its
industry standard CAN bus communication port. The Curtis 1310 seamlessly works in
conjunction with Curtis CAN based SepEx and AC motor controllers such as the, 1243, 1244,
1234, 1236 and 1238.
Model 1310 can be applied to electric vehicles, non-electric vehicles or stationary control systems.

2- INSTALLATION AND WIRING
INSTALLATION AND WIRING
MOUNTING THE CONTROLLER
The Curtis 1310 mounts securely to the vehicle or system using 4 #8 or M4 screws. Care should
be taken to prevent water from splashing or resting on the connector area. If possible, the
connector area should be mounted downward and guarded from water and dust born
contaminants which can degrade the electrical connections.

You will need to take steps during the design and development of your end product to ensure
that its EMC performance complies with applicable regulations; see Appendix B for suggestions
on managing EMC.
The Curtis 1310 Vehicle System Controller contains ESD-sensitive components. se appropriate
precautions in connecting, disconnecting, and handling the controller. See installation
suggestions in Appendix B for protecting the controller from ESD damage.
1310 Vehicle Control System Users Manual Release Rev B Page 6 of 51
Working on electrical systems is potentially dangerous. You should
protect yourself against uncontrolled operation, high current arcs, and
outgassing from lead acid batteries:
UNCONTROLLED OPERAT ON — Some conditions could cause the system to
run out of control. Disconnect motors, open valves and jack up the vehicle to get
the drive wheels off the ground before attempting any work on vehicle control
circuitry or software.
H GH CURRENT ARCS — Batteries can supply very high power, and arcing
can occur if they are short circuited. Always open the battery circuit before
working on the system electrical circuit. Wear safety glasses, and use properly
insulated tools to prevent shorts.
LEAD AC D BATTER ES — Charging or discharging generates hydrogen gas,
which can build up in and around the batteries. Follow the battery
manufacturer’s safety recommendations. Wear safety glasses.

HIGH CURRENT CONNECTIONS
The Curtis 1310 has several options from supply power to the controller. Since the 1310 Vehicle
System Controller has many outputs, it is possible to draw a significant load from the battery.
The B- high power tab must be used as the controller ground reference if more than 2 amps
current is expected in the total system. Likewise, if the system could draw more than 2 amps of
current from the B+, the B+ high power tab must be used to power the controller. If the driven
loads are inductive, the load's power must be connected to B+ high power tab and the B+ high
power tab must be connected to the battery (as shown in the standard wiring diagram).
When using the high power connections tabs, be careful not to bend or break the tab while
tightening the bolt. For best results, use a pressure washer (convex side up) under the bolt head.
This will help prevent the joint from loosening over time.
To help prevent overheating the joint, insure the that wire cable gage is sufficient to carry the
continuous and maximum loads that will be seen by the 1310.

LOW CURRENT CONNECTIONS
All low current (logic) connections are made through Molex Mini Fit Jr connectors. J1 is a 24 pin
connector and contains most of the standard inputs and outputs. J2 is 6 pin connector dedicated
to the CAN bus. J3 is a 4 pin connector dedicated to the Curtis serial bus port, used with the
1311 and 1314 programmers and the 840 Spyglass gage. J4 is a 16 pin connector for the analog
input/outputs and encoder connections.
Low urrent wiring re ommendations
En oders
All four encoder wires should be bundled from the encoder to the controller connector. These
can often be run with the rest of the low current wiring harness. The encoder cables should not
be run near battery or motor cables. In applications where this is necessary, shielded cable
should be used with the ground shield connected to the I/O ground at only the controller side.
In extreme applications, common mode filters (e.g. Ferrite beads) could be used.
CAN bus
It is recommended that the CAN wires be run as a twisted pair. However, many applications at
125 kBaud are run without twisting, simply using two lines bundled in with the rest of the low
current wiring. CAN wiring should be kept away from the high current cables and cross it at
right angles when necessary.
All other low urrent wiring
The remaining low current wiring should be run according to standard practices. Running low
current wiring next to the high current wiring should always be avoided.
Notes on the following tables
The proceeding tables are grouped by connector. They define the pin, signal name and basic
function (description) of that signal. Often special VCL functions can be used to access or setup
or use of these signals. The VCL Functions column notes these when appropriate. Each signal
has a predetermined variable name or set of variable names that allow the VCL access to the
value or control over the signal. These names are in the VCL References column
Partial Option Models
Model 1310-5210 is not “fully stuffed”. This model has Outputs 9 through 16 and Inputs 1
though 13, 16, and 19 through 22 available. Outputs 14 and 15 have over 200kΩ output
impedance.
