InteliDrive Nano is a comprehensive controller for single industrial engines including the electronic EFI engines. InteliDrive Nano controller is equipped with a powerful graphic display showing icons and symbols without texts for its intuitive operation, which sets, together with high functionality, new standards in engine control. InteliDrive Nano can operate an engine in MANual or AUTomatic modes. The key feature of InteliDrive Nano is its easy-to-use operation and installation. Predefined configurations of typical applications are available as well as user-defined configurations for special applications.
One of the key features of the controller is its high level of adaptability based on the needs of every particular application. The way, how to achieve this, is the configuration. NOTE: Use DriveEdit PC software to the read configuration from the controller or disk, view it, modify it and write the configuration to controller or disk. The firmware contains a number of binary inputs and outputs needed for all necessary functions available in the firmware. However not all functions are required at the same time. Configuration task is mapping of "logical" firmware inputs and outputs to the "physical" hardware input and output terminals and some setpoints modification.
1. Mapping of logical binary and analog inputs (functions) to physical binary input terminals 2. Mapping of logical binary outputs (functions) to physical binary output terminals 3. Assigning sensor characteristics 4. Selecting of ECU type if an ECU is connected 5. Setpoints modification
The controller is delivered with a default configuration, which should suit to most standard applications. This default configuration can be changed either directly from controller’s front panel or by using PC with DriveEdit software.
NOTE: For connection to PC please use the USB interface. Controller can be powered directly from USB communication port. In this case LCD backlight is turned off and all outputs are open.
Configuration of InteliDrive Nano controller can be stored in an “ain” file for later use or for its modification in DriveEdit PC software. Such file is called archive. The archive contains full image of the controller at the moment of saving. Besides the configuration there is also recorded actual adjustment of all setpoints as well as all measured values and history logs.
The archive can be simply used for preparing controllers with identical configuration and settings.

Engine Speed control in MAN mode
Engine starts to R02-Idle Speed, increases after Idle time to the R03-Operational Speed that can be changed by panel Up/Down buttons, switched by Binary input I-28 Speed Switch to another “R04-Speed Switch” value that can be again changed by panel Up/Down buttons and returns to previous value of R03-Operational Speed.
All RPM changes are accepted within R15-Max and R16-Min Speed Limits. Operational and Speed Switch change (by Up/Down buttons) is remembered in case of switching by Binary input Speed Switch for all time engine is running. After Engine Start are R03-Operational Speed and R04-Speed Switch actualized to default R03, R04 setpoint values.

Sensor fail is indicated below ½ of low and over +12% of high limit of sensor characteristic.
To ensure proper function: Use min. power supply cable of 2.5mm2 Maximum continuous DC power supply voltage is 36 VDC. Maximum allowable power supply voltage is 39VDC. The InteliDrive Nano power supply terminals are protected against large pulse power disturbances. When there is a potential risk of the controller being subjected to conditions outside its capabilities an outside protection devise should be used. For the connections with 12VDC power supply, the InteliDrive Nano includes internal capacitors that allow the controller to continue operation during cranking if the battery voltage dip occurs. If the voltage before drop is 10V, after 100ms the voltage recovers to 5 V, the controller continues operating. During this voltage drop the controller screen backlight can turn off and on but the controller keeps operating.
Power supply fusing Controller should never be connected directly to the starting battery. App 6 amp fuse should be connected in-line with the battery positive terminal to the controller. Fuse value and type depends on number of connected devices and wire length. Recommended fuse (not fast) type - T1A. Not fast due to internal capacitors charging during power up. The capacitor size should be 5 000 µF to
withstand 150ms voltage dip under following conditions: Voltage before the drop is 12V, after 150ms the voltage recovers to min. allowed voltage, i.e. 8V.
D+ Charging alternator D+ output is on terminal T02. Hint: Do not leave it opened. If not used connect T02 D+ terminal to battery positive T03.
Binary outputs Use minimally 1 mm2 cables for wiring of all binary outputs. CAUTION! Controller Binary outputs are high side type (connecting +VBatt on output terminal) ! Never connect any analog sensor to this output to avoid sensor damage. All outputs are short circuit protected. Use suppression diodes on all relays and other inductive loads!
Analog inputs Analog inputs are designed for resistive automotive type sensors like VDO or DATCON. The sensors are connected either by one wire (the second pole is sensor body) or by two wires.
• In case of grounded sensors connect the terminal T10 to the engine body as near from the sensors as possible.
• In case of isolated sensors connect the terminal T10 to the negative power supply terminal of the controller as well as the opposite poles of the sensors.
NOTE: Symbol #### is displayed when measured value is out of range or sensor’s wire is broken.

Data from ECU The analog measuring T14–Oil Pressure and T15-Coolant Temperature has to be configured as Not used (function code I00) to display those ECU values on the second screen “when ECU is configured”. Engine RPM is switched to ECU source automatically. The ECU Fault codes are reported in the Alarm-History Screen as well as the ECU communication fail.
Setup mode is available when: • Engine is not running, • Controller is in MAN mode, • Panel Up/Dn keys are switched to Screen listing mode. •
The Setup mode is blocked by the binary function Access lock as well as the Menu button.
To enter Setup mode press and hold then press shortly button and then and then . Setup mode enables partial controller configuration (I/O function modification and setpoints setting) using just panel buttons without PC tool. NOTE: The controller will automatically switch to Setup mode when there is some problem with checksum (i.e. memory integrity) or when there is incompatibility between firmware and archive version. This situation can occur when you upgrade a firmware. If this happen just check and set all setpoints properly.
Inputs and Outputs In the table below you can see which logical function can be assigned to physical binary or analog input or binary output. Each logical input or output function has unique code. Input code’s firs letter is “I” output code’s letter is “O”. Summary of all logical input function is in chapter Logical binary and analog inputs, summary of logical output function is in Logical binary outputs. Each logical binary input and output can be configured as Normally Open (NO) or Normally Close (NC).
Physical Inputs Terminal Type Direction Input function assignment
Normally Open contact Normally Open contact – no voltage on output terminal or no passing current from/to binary input terminal. When the contact is opened controller read logical 0 (L) on binary input when is closed controller read logical 1 (H). In case of output logical 0 (L) means 0V on binary output and logical 1 (H) means battery positive voltage on output.
Normally Closed contact Normally Close contact (inverted) represents close contact – positive voltage on output terminal or passing current from/to binary input terminal. When the contact is opened controller read logical 1 (H) on binary input when is closed controller read logical 0 (L). In case of output logical 1 (H) means 0V on binary output and logical 0 (L) means battery positive voltage on output.
For outputs configuration use PC software DriveEdit or switch controller to Setup mode. On the picture below is example how to configure binary output via front controller’s screen. At first you have to select output terminal. For move use and buttons for choice press Start button and Stop button for return. Then pick out logical function (O00-O09) and select contact type (Normally Open contact or Normally Closed contact) and confirm change.

Shutdown procedure InteliDrive Nano controller opens outputs O01 Starter, O08 Prestart and O02 Fuel Solenoid or close O03 Stop Solenoid to stop the engine immediately. O04 Alarm output is closed. Active or not confirmed protection disables start.
Active unconfirmed shutdown When shutdown comes up, Shutdown procedure will start, red LED above Stop button starts blinking. Shutdown symbol will start blinking on up-and-right LCD corner and proper shutdown symbol is displayed in history with running hours stamp. The record in history is negative, see picture below. See list of Possible shutdown alarms. For shutdown alarm confirmation press Stop button
Active confirmed shutdown When active shutdown is confirmed the red LED above the Stop button stops blinking. The record in history stays negative with confirmation symbol at the end. O04 Alarm output endures closed.
Inactive unconfirmed shutdown O04 Alarm output is closed, red LED above Stop button is shining. Shutdown symbol is displayed on right up LCD corner and proper warning symbol is displayed in history with running hours stamp, see picture below. See list of possible shutdown alarms. For shutdown alarm confirmation press Stop button
Inactive confirmed shutdown O04 Alarm output is opened. It is possible to start engine when all shutdowns are inactive and confirmed.
Possible shutdown alarms
Emergency Stop The binary input Emergency Stop was activated.
Overspeed The protection comes active if the speed is greater than 115% of nominal engine RPM
Underspeed Low engine RPM. This alarm will be issued when the is running and then stops by itself, i.e. the RPM drops under the nominal engine RPM. The underspeed alarm starts to be evaluated 5 sec after successful start and is being evaluated all the time the fuel solenoid is on.
Low Oil Pressure Engine will stop when oil pressure declined to or less than 1 bar or binary input I22 Low Oil Pressure is active.
High Coolant temperature Engine will stop when temperature of coolant exceed Coolant Temperature Shutdown threshold.
External Shutdown 1
Start Fail start failed.
Stop Fail stop failed.
Battery Flat If the controller switches off during starting sequence due to bad battery condition it doesn’t try to start again and activates this protection.
