Volvo TAD ECU frequency selection procedure (EMS2):
1. ECU switched ON
2. press STOP button
3. change from Primary to Secondary or the other way around
4. press STOP button
5. power OFF the ECU for 15 seconds or more
6. power ON the ECU
The whole procedure (step 2 to 3) must not exceed 10 seconds.
ECU SpeedAdj [%]
Enables to adjust engine speed in ECU via CAN bus. Nominal speed corresponds to 50%.
Step: 1%
Range: 0 – 100%
Hint:
The minumim value 0% is equal to 90% of nominal speed. Maximum value 100% is equal to 110% of
nominal speed.
Fuel Pump ON [%]
When the actual value of Fuel Level (AI 3) is lower or equals to this value then the binary output Fuel
Pump is activated.
Step: 1
Range: 0 – 100 %
Fuel Pump OFF [%]
When the actual value of Fuel Level (AI 3) becomes higher or equals to this value then the binary
output FUEL PUMP is deactivated.
Step: 1
Range: 0 – 100 %
Preheating ON [°C]
When the actual value of Water Temp (AI 2) is lower or equals to this value then the binary output
PREHEATING is activated.
Step: 1
Range: 0 – Preheating OFF °C
Preheating OFF [°C]
When the actual value of Water Temp (AI 2) becomes higher or equals to this value then the binary
output PREHEATING is deactivated.
Step: 1
Range: Preheating ON – 100 °C
Hint:
Preheating function is switched off when Preheating ON = Preheating OFF.
The two setpoints above are compared to Analog Input 2 (usually used for Water Temp)
For more details about Preheating function see description of PREHEATING binary output
Comparator IN [AI1; AI2; AI3; IOM AI1; IOM AI2; IOM AI3; IOM AI4]
Input to the comparator, it is possible to choose what analog input will be evaluated
Comparator ON [ ]
Resolution = 1
ON limit - once this limit is reached the Comparator output is switched on.
