0-36 V Wiring Example
CAUTION
A TVS (I.E., VARISTOR) IS REQUIRED IF THE BATTERY IS DIFFERENT THAN THE BATTERY
FROM WHICH THE CONTROLLER IS POWERED. THE CONTROLLER’S TVS CANNOT PROTECT
THE SENSOR INPUT FROM TRANSIENTS IN THIS CASE.
ATTENTION
UN TVS (VARISTANCE) EST NECESSAIRE SI LA BATTERIE EST DIFFERENTE DE CELLE QUI
ALIMENTE LE CONTROLEUR. DANS CE CAS, LE TVS DU CONTROLEUR NE PEUT PAS
PROTEGER L'ENTREE CAPTEUR CONTRE LES TRANSITOIRES.
2.6.4 CANbus Wiring (J1939)
The following table outlines some items that must be taken into consideration when connecting to a CANbus
engine.
Consideration Description
Bus Termination Each end of the bus must be terminated from CAN H to CAN L with 120
Ω +/- 10 Ω
resistors. The resistor must be able to handle at least 400 mW of power dissipation.
Cable Selection A twisted pair 120
Ω impedance cable is required for communications. For better
protection, a shielded twisted pair cable is recommended.
Examples include the following:
•
Belden 9841 - Shielded cable with one twisted pair, 24 AWG
•
Belden 7895A - Shielded cable with two twisted pair, 20 AWG
For short runs of 5 ft or less, regular 18 AWG wiring can often be run.
Shielding If using a shielded cable, the shield must be connected to ground on one end of the
bus only. This prevents loss of data from electromagnetic interference.
Termination at the
Controller The twisted pair cable must terminate no farther than six inches from the controller
’s
CAN (J1939) connector. Three inches is ideal.
