P_09

 

STARTING RPM FUEL 

parameter adjusts the fuel amount during engine cranking.  

A high starting fuel adjustment helps the engine to fire faster.  

However the minimum necessary amount of starting fuel should be used in order to minimize engine exhaust 
smoke during cranking.

 

 

 

The Speed Ramp adjusts the time that the engine requires to reach the nominal speed from idle speed. 

The engine will ramp faster to the nominal speed with increased values of  

P_11

. 

 

 

If the engine rpm goes over 

P_03 Delayed Overspeed Limit

 during 

P_05 Overspeed Delay Timer

, this 

will generate overspeed alarm. Overspeed alarm is set immediately if the engine rpm is above 

P_04 

Immediate Overspeed Limit

.  

When an overspeed alarm occurs, 

OVERSPEED

 and 

ERROR

 leds will turn on and 

“

err6

” message is 

displayed on the screen. 

Hold pressed 

and

 

 

buttons together to reset overspeed alarm. 

 

 

P_25 Save Configuration

 parameter allows user to save the current configuration of the device.  

The device offers 14 different memory locations to save the configuration. Thus different configurations can 
be saved to different memory locations and any of them can be restored later. 

The memory location 1 is reserved for the factory set configuration. It cannot be overwritten, but may be 
restored anytime. 

If the user selects the memory location number from 

P_26 Restore Configuration 

parameter, parameters 

will be automatically configured accordingly.  

In order to return to factory settings, P_26 must be set to1. 

 

 

Firmware update can be done if the manufacturer releases an update about the operation of device.  

The firmware file cannot be read from the unit and it is always required to get the original firmware file 
from the manufacturer. 

To force the device to firmware update mode, 

P_28 Boot Mode

 parameter must be set to 1.  

The unit in BOOT LOADER mode will wait for a PC connection through its USB port. When the unit 
establishes USB connection, the device will be automatically recognized by the PC and will appear as a 
Device with Removable Storage. After deleting firmware file, copy the new firmware provided by Datakom 
into this disk.
