Instruction manual JetCat-PRO engines, 1.7 - V12.01V
Note 1:
Power On Signal (Pin 9) treatment:
Normally the ECU will switch off instantly if the control voltage on this pin is removed.
However this default behavior depends on the selected operation mode as well as on the setting of parameter “Self
Power funct.” (
Limits menu).
Parameter “SelfPower funct.” can be set to 3 different options:
1)
“OFF”
In this case the ECU will be instantly depowered when the control voltage on pin 9 is removed, no matter if
the engine is running or not.
2)
“run & cooling”
In this case the ECU will stay powered on even if the control voltage on pin 9 is removed, but only if the
engine is currently running or in cooling mode. This setting ensures that a running engine cannot be
accidentally shut down even if there should be glitches on the power on signal. ECU will only power down if
the engine is not running and cool down has finished.
3)
“cooling”
With this option the ECU will stay powered on as long as the engine still is in cooling mode, even if the control
voltage on pin 9 is removed. As soon as cooling is finished, the ECU will turn off. This ensures that the cooling
cycle will be completed even if the power on signal should be removed after normal commanded shut down
of the engine.
Important:
If the operation mode is set to “RC model” the system internally uses the “run & cooling” setting. The parameter
“SelfPower funct.” is not visible in this operation mode! This approach avoids accidental engine shuts downs (ECU
power downs) due to possible instable system power supply of the RC-model.
