DESCRIPTION
Smart-CAN is a new addition to the Smart series. It is an intelligent auto start
and protection module with CAN bus J1939 communication protocol, engine
status display, run hour counter and run hours since the last oil change.
Automatic assembly and microcontroller based high integration design resulted
in this low-cost yet high performance controller.

OPERATION
Stop Mode: In this mode, the engine is shut down along with the module. All alarms are reset.
Auto Mode: In this mode, the genset is ready to start. Starting is controlled by the remote control input. Following is a description of the
operation in this mode:
1. The Remote Control input receives a start signal (activated by connection to –Vbat).
2. No action is taken until the delay set by RSP is elapsed.
3. A starting sequence of a preset number of attempts ATT will initiate.
4. The Electric Valve engages 0.5sec before the Starter.
5. If the start signal is removed before the engine starts, all timers are reset and the module is ready for a new sequence.
6. Cranking is disconnected when the RPM (divided by 60 to convert it to Hz) received through the CAN bus exceeds CRF or a voltage
exceeding dCd (if not set to bYP) appears on the Dynamo input or the oil pressure switch opens given that boP is not set to bYP
and its preset delay has elapsed or for Volvo engines, when a running indication is received through the CAN bus.
7. If the engine fails to start after the preset number of attempts, a scan of the six red leds is initiated to indicate a start fail. The Alarm
output is activated. The Smart-CAN would reattempt starting by selecting the Stop Mode then selecting Auto Mode or by recycling
the remote control signal.
8. After elapse of the warm-up delay, set by WUP, the load contactor is engaged via terminal Contactor and yellow led activated.
9. All protections are enabled when the engine is running and after the elapse of the fault bypass time set by bYP.
10. Any fault will shut the load down and then shut the engine down and the corresponding led is lit. Alarm output is activated as well.
11. When the start signal is removed, the Smart-CAN will shut the load down after the elapse of the delay set by oFF. The engine is shut
down after the elapse of the cooling time set by COL.
Manual Mode: This mode is similar to the Auto Mode except that the start signal is internally activated.

DISPLAY FUNCTIONS
Genset status: while standing-by for a start signal in Auto Mode, the display shows READY if the genset is ready to start. In case the genset is
not ready, NOTRdY is displayed. This could be the result of three causes: oil pressure switch not connected (or damaged), dynamo input sees a
voltage exceeding dcd or running status was received through the CAN bus. If there is no oil pressure switch, set boP to bYP. If there is no
dynamo (or dynamo not connected), set dCd to bYP and dSd to diS. The display will show CRANKG during cranking and it will also show the
count down of the response, warm-up, load shutdown (off delay) and cooling delays. Following a shutdown due to a fault, the display will show
the DTC (J1939 protocol error code) description of the fault received from the CAN bus. The LCD will show RUNING when the engine is
running, LOADOK when engine is running on load.
Measurements: The LCD also displays measurements received by the module from the engine through the CAN bus. Displayed measurements
o
are: oil pressure (PSI), engine coolant temperature ( C), fuel consumption (Liters/hour), battery voltage (Vdc), engine speed (RPM), engine total
hours of operation (Hr) and the engine total fuel consumption (L). The display also shows the run hours since the last oil change (recorded by
the Smart-CAN). When the oil run hour reaches RHR, the low oil pressure indicating led will start blinking. Following an oil change, the oil hour
counter can be reset to zero by pressing simultaneously AUTO and HAND push buttons for 2 seconds. Autoscrolling between these
measurements can be done by pressing the AUTO or HAND push button (user should press the one that is already active so as not to change
the operating mode).

ACCESSING THE MENU

The menu is accessed by pressing either AUTO or HAND push buttons for 3 seconds. Once in menu mode (i.e. scrolling the menu and editing
parameters), the AUTO and HAND push buttons will no longer affect the operating mode of the Smart-CAN controller. The AUTO push button
scrolls down the menu and decrements values. The HAND push button selects the menu item for editing and increments values. The new value
will be automatically memorized after 2 seconds if no push buttons are pressed. If no buttons are pressed for 25 seconds, the Smart-CAN will
automatically exit the menu mode.
