2 Introduction
2.1 Automatic Operation
The CANplusTM CP750 panel features advanced Automatic Start/Stop control which can meet almost any
requirement. Two switch inputs and a transducer input support a number of control scenarios.
Single switch mode allows reliable operation with a single switch. Dual switch operation allows greater hysteresis
when needed.
The transducer input supports simple start/stop operation by level or pressure and maintenance modes with
speed modification, as follows:
•Programmable high and low set points control start/stop operation
•Level maintenance modes monitor the operating point and adjust the engine speed to match the
targeted set point with configurable aggressiveness
•Dual switch inputs can be combined with the transducer input for redundant safety to protect against
transducer sensor clog or failure
2.2 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 CAN bus throttle control.
Note: Throttle control requires CAN bus throttling to be enabled in the ECU. CAN bus throttling is also known
as Torque Speed Control or TSC1.
Other throttle options include Digital Rotary Throttle, Two-State Throttle (Idle/Run) or Three-State Throttle
(Idle/Intermediate/Run). The Digital Rotary can be installed with the Throttle Ramp Throttle or Three-State
Throttle to adjust the Idle, Intermediate and Run speeds.
2.3 CANplusTM Messenger Telemetry Option
The optional CANplusTM Messenger system provides a variety of features to protect and support the equipment
investment. Remote monitoring can alert maintenance requirements, operational problems, improper operation
and location with a geo-fence alert. The Web-browser interface allows for monitoring an entire fleet of equipment
in a central location. Contact Cattron at www.cattron.com/contact for more information.
2.4 Mechanically Governed Engines
On mechanically governed engines, the CANplusTM I/O Board performs the ECU function by monitoring low oil
pressure, high temperature and two additional engine faults. Three analog inputs broadcast the oil pressure,
engine temperature and fuel level across the CAN bus to the display and other J1939 devices, as indicated in
the display image in the following figure. The engine speed can be controlled using a mechanical throttle or by
using the standard CP750 throttle controls with the optional CANplusTM Actuator Kit. Automatic throttling with
automatic start/stop requires the use of the CANplusTM Actuator Kit. Only single speed operation is possible with
a mechanical throttle.

3 Overview
The CANplusTM CP750 control panel is a universal platform to monitor, control and automatically start/stop both
electronically and mechanically governed diesel engines. The microprocessor-based, solid-state design uses
high power semiconductors instead of outdated electromechanical relays to ensure reliable high current
switching. 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. An analog fuel level input
broadcasts the fuel level across the CAN bus to the display and other J1939 devices. The trans-reflective, backlit
display is clearly readable in both bright sunlight and total darkness and is housed in a rugged IP66 rated
housing.
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. Engine state information and diagnostic
codes displayed by the CANplusTM display are provided via the CAN bus.

4.5 Digital Transducer Gauge
The Digital Transducer Gauge displays the transducer value as a digital only value. The switch state is not
displayed on the Digital Transducer Gauge.
4.6 Active Alarms
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 CAN bus 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. Four bright LEDs below the display indicate Auto Standby,
Preheat, Stop and Warning status.
A flashing popup window is overlaid on the current screen when an active alarm is received. The popup includes a
plain language description in addition to the standard SPN/FMI (Suspect Parameter Number/ Failure Mode
Indicator) pair defined by the SAE J1939 standard. Additionally, if enabled, the beeper sounds as an audible cue.
The following figure shows three different alarm screens: an example alarm message (left image), an alarm list
screen showing unacknowledged conditions (middle image) and an alarm list screen showing acknowledged
alarms (right image).
After acknowledgement, the exit button becomes active.
Note: Standard J1939 abbreviations are used for alarms, as follows:
MS = Most Severe

CANplusTM CP750

4.7 Alarm List
The Alarm List is accessed by pressing any button while an alarm popup is displayed or by pressing any of
the first four buttons to show the button bar and then pressing button 4 . Alarms not yet acknowledged
are shown in grey text on a black background, while acknowledged alarms are shown in black text on a grey
background. The list also indicates when the alarm occurred if engine hours are available. The most recent
alarm is displayed at the top of the list. The list can be scrolled using buttons 1 and 2 . Alarms are
acknowledged by pressing button 3 . The Alarm List can be closed by pressing button 5 once the
alarms are acknowledged.
An alarm indicator is displayed near the upper right corner of the display as long as alarms are active. The
indicator and alarm messages in the list are automatically removed when the alarm is no longer received for a
few seconds.
Note: Only active faults are displayed in the alarm list. Once a fault is corrected, it is automatically removed
from the list. To view previously active faults, use the engine diagnostic tool.
4.8 Service Timers
The CP750 display provides 16 service timers to alert the operator of needed maintenance. The time interval for
each timer 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 message is displayed on each power-up until the
elapsed timer is disabled or reset.

9M02-1000-A101-EN
Revision B
5 Manual Operation
Turning the control system key to the run position energizes the ECU, and all LEDs illuminate once, and a start-
up screen is displayed while a self-test is performed. If the display beeps for longer than one second, it indicates
a self-test fault. Users can attempt to rectify the fault by restoring factory defaults (see the Configuration Menu
section for more details). Contact Cattron at www.cattron.com/contact for assistance if the fault persists.
After the start-up screen is cleared, the display shows readings on its virtual gauges. Initially, the analog gauges
are displayed but the display uses the last displayed screen on subsequent startups (see the Preferred Screen
Store section for details).
If the ECU is preheating when the key switch is turned to the run position, the 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 includes an
interlock to prevent the key from being turned to the start position while the engine is running. The key switch must
be turned to the off position to reset the starter interlock before the switch can be turned to the start position again.
5.1 Throttle Control
The type of throttle that operators installed, along with the configured values of Minimum Requested RPM, Idle
RPM, Intermediate RPM, Run RPM and Maximum Requested RPM,determine throttle operation. The engine
speed can be adjusted above Run RPM and below Idle RPM, but the requests cannot fall below the Minimum
Requested RPM or above the Maximum Requested RPM. The ECU determines how the engine responds to
the throttle requests and will not allow the engine speed to fall below the ECU minimum or maximum RPM.
Note: The Minimum Requested RPM and Maximum Requested RPM can be configured using the
CANplusTM Configurator. See the Configuration section for more information.
5.2 Ramp Throttle
The standard Ramp Throttle uses a momentary rocker switch to adjust the requested engine speed. When
first started, the requested engine speed is Idle RPM. Pressing and releasing the rabbit icon increases the
speed requested by 25 RPM. Pressing and holding the rabbit icon causes the speed to accelerate to full
speed in a few seconds. Similarly, pressing the turtle icondecreases the requested speed.
5.3 Two-State Throttle
The optional Two-State Throttle uses a two-position rocker switch to adjust the requested engine speed.
Pressing the rabbit icon requests the engine to go to Run RPM. Pressing the turtle icon requests
the engine to go to Idle RPM.
5.4 Three-State Throttle
The optional Three-State Throttle uses a three-position rocker switch to adjust the requested engine speed.
Pressing the rabbit icon requests the engine to go to Run RPM. The intermediate position requests the
engine to go to Intermediate RPM. Pressing the turtle icon requests the engine to go to Idle RPM.

CANplusTM CP750
Control Panel Operation Manual

9M02-1000-A101-EN
Revision B
5.5 Digital Rotary Throttle
The optional Digital Rotary Throttle uses a rotary switch to simulate the operation of a throttle potentiometer.
Like the Ramp Throttle, when first started the requested engine speed is Idle RPM. Turning the throttle knob
clockwise increases the requested engine speed. Turning the throttle knob counter-clockwise decreases the
requested engine speed.
Note: When used in combination with the Three-State Throttle, the Rotary Throttle can only be used to make
speed adjustments when the switch is in the intermediate position.
The Rotary Throttle can be used to reprogram the Idle, Intermediate and Run RPMs when used in
combination with the Ramp Throttle or Three-State Throttle. After adjusting the engine to the desired speed
with the throttle knob, press and hold the knob and then press and hold the throttle switch position to be
changed. After two seconds all LEDs will flash, indicating the current speed has been stored. The knob and
switch can now be released.

6 Automatic Start/Stop Operation
Turning the control system key to the Autostart position causes all LEDs to illuminate once, the Auto
Standby indicator is illuminated and the start-up screen is displayed while a self-test is performed. After the
start-up screen is cleared, the display shows the transducer reading and switch status on the Analog
Transducer/Switch Gauge. All other CAN bus values will show since the ECU is not energized at
this time. After one minute the display is powered down to reduce battery drain. The automatic start/stop
system is still functioning as indicated by the Auto Standby LED.
Once the configured automatic start condition exists, the display powers up, and the panel starts the engine
