Maretron ENGINE MONITORING SYSTEM EMS100 Manual De Usuario

 

 

 

6:  Fuel Rate – (16-bit signed integer) This field indicates the fuel consumption rate of 

the engine in units of 0.0001 cubic meters / hour. The EMS100 does not provide a 
value for this field. 

 

7:  Total Engine Hours – (32-bit unsigned integer) This field indicates the cumulative 

runtime of the engine in units of 1 second. 

 

8:  Engine Coolant Pressure – (16-bit unsigned integer) This field indicates the pressure 

of the engine coolant in units of 100 Pa. The EMS100 does not provide a value for 
this field. 

 

9:  Fuel Pressure – (16-bit unsigned integer) This field indicates the pressure of the 

engine fuel in units of 1000 Pa. The EMS100 does not provide a value for this field. 

 

10:  Reserved – (8 bits) This field is reserved by NMEA; therefore, the EMS100 sets all 

bits to a logic 1. 

 

11:  Engine Discrete Status 1 – (16 bits) This field indicates warning conditions of the 

engine with the following bit assignments (value of 1 indicates warning present): 

Bit 0: Check Engine - The EMS100 always transmits a value of 0 for this field. 
Bit 1: Over Temperature 
Bit 2: Low Oil Pressure 
Bit 3: Low Oil Level - The EMS100 always transmits a value of 0 for this field. 
Bit 4: Low Fuel Pressure - The EMS100 always transmits a value of 0 for this 

field. 

Bit 5: Low System Voltage - The EMS100 always transmits a value of 0 for this 

field. 

Bit 6: Low Coolant Level 
Bit 7: Water Flow 
Bit 8: Water in Fuel 
Bit 9: Charge Indicator 
Bit 10: Preheat Indicator 
Bit 11: High Boost Pressure 
Bit 12: Rev Limit Exceeded - The EMS100 always transmits a value of 0 for this 

field. 

Bit 13: EGR System - The EMS100 always transmits a value of 0 for this field. 
Bit 14: Throttle Position Sensor - The EMS100 always transmits a value of 0 for 

this field. 

Bit 15: Emergency Stop Mode 

 

12:  Engine Discrete Status 2 – (16 bits) This field indicates warning conditions of the 

engine with the following bit assignments (value of 1 indicates warning present): 

Bit 0: Warning Level 1 - The EMS100 always transmits a value of 0 for this field. 
Bit 1: Warning Level 2 - The EMS100 always transmits a value of 0 for this field. 

Bit 2: Power Reduction - The EMS100 always transmits a value of 0 for this 
field. 

Bit 3: Maintenance Needed - The EMS100 always transmits a value of 0 for this 

field. 

Bit 4: Engine Comm Error - The EMS100 always transmits a value of 0 for this 

field. 

Bit 5: Sub or Secondary Throttle - The EMS100 always transmits a value of 0 for 

this field.
