ECU Throttle Settings
Controls, Inc. panels use J1939 throttle, also called TSC throttle (torque/speed control). This is
different from the older analog and digital throttle options provided in engine ECU's. Two throttle
settings need to be implemented in the engine ECU.
1) TSC throttle needs to be enabled in the engine ECU settings
2) TSC address needs to be matched to control panel throttle setting
Most engine ECU today have TSC enabled as a default setting but for situation where it is not, the
engine ECU needs to be updated with this setting enabled. The control panel has a number of TSC
addresses that can be selected to match the engine ECU setting.
CAN bus Wires
With J1939 engines, all of the communications between the engine ECU and the control panel oc-
curs over the two CAN bus wires. This includes the engine information (like oil pressure, engine
speed, alarm codes and alarm lamps) going from the engine ECU to the control panel and throttle
commands going from the control panel to the engine ECU. If there is a break in the CAN bus
wires, communications stop and the control panel displays a CAN bus error message. Also, in spark
ignition engines, CAN bus wires should located away from the spark plug wires, distributor cap and
ignition coil to avoid EMI from these high voltage components.
Proper Diode Installation
The proper installation of diodes protects the control panel and other electrical components (such as
the engine ECU) from transient voltage spikes generated whenever any relay (coil) in the system is
de-energized. See diode protection for more details. 1939 engine harnesses provided by the engine
manufacturer or Controls, Inc. follow proper diode protection specifications.
Relay Outputs
Many of our products provide for relay outputs that can be used to drive other components and de-
vices. These outputs are rated for a maximum current draw of 5 to 10 amps. For components or de-
vices that draw more that this (such as a starter or glow plug circuit), it is necessary to install a slave
relay that is diode protected into the circuit. Controls, Inc. can provide any necessary slave relays.
