Low Current Connections - Curtis 1310 Manual

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 current wiring recommendations
Encoders
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 current 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 200 output
kΩ
impedance.
