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.
Five buttons access a context dependent button bar when any
button from 1 to 4 is pressed. The graphical menu structure
uses easily understood icons to indicate the button’s current
function. After 5 seconds of inactivity the button bar
disappears.

Note
Most problems with electronically controlled engines can be pinpointed via ECU diagnostic
messages. Use the display or ECU diagnostic tool to view fault codes.
All engine state information and diagnostic codes
displayed by the CANplus display are provided via the CANbus.
Throttle Control
The standard ramp throttle uses a momentary rocker switch to adjust the integral throttle control. All throttle
commands are sent directly to the engine using CANbus throttle control.
Note
Throttle control requires CANbus throttling to be enabled in the ECU.
CANbus throttling is also identified as Torque Speed Control and TSC1.
Rotary potentiometers are available for ECUs that do not support CANbus throttle control.
Other throttle options include digital rotary hand throttle, two-state throttle rocker switch (idle/run) or three-
state throttle rocker switch (idle/intermediate/run). The three-state throttle rocker switch can be used in
conjunction with the digital rotary hand throttle to adjust the intermediate speed.
Service Timers
The CP600 panel provides sixteen (16) service timers to alert the operator to needed maintenance. The time
interval for each of the timers can be adjusted in 10 hour increments. A popup message is displayed after
the display self test if a timer has expired alerting the user that service is required. The popup message
continues to be displayed at power up until the timer is disabled or reset.
Telemetry Option
The optional telemetry system provides a variety of features to protect and support your equipment
investment. Remote monitoring can alert maintenance requirements, operational problems, improper
operation and theft. The Web-browser interface allows monitoring an entire fleet of equipment in a central
location.
LED Option
Four optional bright LEDs indicate Power, Preheat, Stop and Warning status. These LEDs are controlled
directly by the ECU.
Warning
When replacement parts are required, LOFA Industries recommends using replacement parts
supplied by LOFA or parts with equivalent specifications.
Failure to heed this warning could lead to premature failure,
product damage, personal injury or death.

Operation
Turning the control system key to the run position
energizes the ECU and displays a start-up screen
while the display performs a self test. If the display
beeps for longer than 1 second, it indicates a self
test fault. Users can attempt to rectify the fault by
restoring factory defaults (see Configuration Menu
for details). Contact LOFA Industries for assistance if
the fault persists.
After the start-up screen disappears, the display
shows readings on its virtual gauges. Initially the
analog gauges are displayed but the display uses
the screen last displayed on subsequent startups (see
Preferred Screen Store for details).
If the ECU is preheating when the key switch is turned to the run position, the optional Preheat LED is
illuminated. Preheat time varies with atmospheric and engine conditions. After waiting for the Preheat LED to
extinguish, the engine is cranked by turning and holding the key switch in the start position until the engine
starts.
Note
The ECU will not preheat unless conditions warrant. If necessary, starting the engine may be
attempted by turning the key to the start position without waiting for preheat to expire.
The key switch is spring loaded to return automatically to the run position when released. The key switch is
equipped with a mechanical start locking device. An attempt to re-crank the engine can only be made by
turning the key switch to the off position to reset the start locking mechanism.
CANplus Display
Soft buttons simplify the operator interface by displaying a button bar above the buttons when any of the first
4 buttons (buttons 1 to 4, starting from the left) are pressed. Icons on the button bar representing the current
function of each button. The button bar disappears after 5 seconds if no further buttons are pressed.
Note
Different software versions may have slightly different displays.
