The discrete inputs are capable through software programming to
change the logic or state of the input. Please verify the state of your
input before starting the engine.
Close to Run or Minimum Fuel (Terminal 34)
(Discrete Input A)
The external contact used to activate the Close to Run command connects to
terminal 34. This discrete input changes the control operation by immediately
decreasing the fuel demand to zero. When the switch or relay contacts are
closed, the control is allowed to control the fuel in an attempt to control the
speed/load of the prime mover. When the switch or relay contacts are open, the
Minimum Fuel Function will immediately pull the fuel demand to zero.
Do NOT use the minimum fuel contact as part of any emergency stop
sequence.
