Introduction
The CANplus™600 (CP600™) control panel is an
economical platform to monitor and control electronically
governed diesel engines. Graphical gauge pages or a single
large analog gauge are displayed on the 4.25" diagonal
LCD. Virtually any SAE J1939 parameter reported by the
ECU (Engine Control Unit) can be displayed including RPM,
coolant temperature, oil pressure, engine hours, voltage and
diagnostic codes. The trans-reflective, backlit display is
clearly readable in both bright sunlight as well as total
darkness and housed in a rugged IP67 rated housing.
Current alarm conditions are displayed in plain language on
popup messages and can be viewed in the alarm list.
Various diagnostic screens allow detailed investigation of the
CANbus data stream. By accessing the Configuration Menu,
users can customize displayed data to show metric or US
units, display language and various other parameters such
as the full-scale reading of gauges.

Page 20: Typical J1939 Wiring Topology
600 Control Panel Operation and Troubleshooting Typical J1939 Wiring Topology Most electronically governed engine installations include a harness with built in J1939 backbone. Use twisted shielded pair with a drain wire for CANbus wiring terminated with 120Ωresistors at each end. The maximum length for the bus is 131 feet (40 m) and stubs should not exceed 39 inches (1m) in length. -
Page 21: Unsealed Connectors
These chemicals may cause seal damage and allow water entry. Use LOFA provided cavity plugs to seal the connector if wires are removed. Unsealed Connectors For unsealed connectors exposed to the elements, LOFA recommends using dielectric grease to protect contacts. Warning LOFA does not recommend using sealant with unsealed connectors. -
Page 22: Battery Circuit Requirements
A reliable dedicated power circuit must be provided for the control system. LOFA recommends the power connection be made directly to the battery. Grounding through frame members is not recommended! All circuit paths must be capable of carrying any likely fault currents without damage. -
Page 23: Suppression Of Voltage Transients (Spikes)
Warning The installation of voltage transient suppression at the transient source is required. LOFA follows SAE recommended electrical environment practices. Inductive devices such as relays, solenoids and motors generate voltage transients and noise in electrical circuits. Unsuppressed voltage transients can exceed SAE specifications and damage electronic controls. -

Page 29: Diagnostic Trouble Codes (Dtc)
600 Control Panel Operation and Troubleshooting Diagnostic Trouble Codes (DTC) CANbus Diagnostic Trouble Codes are a pair of numbers; the Suspect Parameter Number (SPN) and Failure Mode Identifier (FMI). The SPN indicates the faulting subsystem and the FMI identifies the type of failure. Typical SPNs Standard SPN codes are defined by SAE J1939-71. - Page 30 600 Control Panel Operation and Troubleshooting Data Parameters Monitored This table lists the engine and transmission parameters that are monitored via the CANbus. The parameters can be displayed by the user-configurable gauge pages or the single analog gauge. DB is an abbreviation for the internal database which stores all data transmitted from the engine/transmission.
