Connection Function
CN2-3 G/R Engine oil pressure switch
When engine oil pressure drops to the set
pressure of emergency stop, it makes emergency
controller Ry4 relay ON and it sends abnormality
signal to ECU to stop engine.
●
Emergency stop set oil pressure :
7.1psi(0.049MPa)[0.49bar]
CN2-4 G/R Compressor air filter
It detects clogging of compressor air filter, and it
enables alarm lamp to blink.
●
Differential pressure for warning function :
More than
0.9psi(6.23kPa)[0.06bar]
CN2-5 G/L Engine air filter
It detects clogging of engine air filter, and it
enables alarm lamp to blink.
●
Differential pressure for warning function :
More than
0.9psi(6.23kPa)[0.06bar]
CN2-6 B/G Service pressure sensor
Intake negative pressure sensor
Grounding
CN2-7 G Service pressure sensor Vout
terminal
Detection of service pressure.
CN2-8 Y/R Engine controller (ECU) CN5-94
terminal
It outputs engine speed.
●
Revolution ratio (pulse type) :
6 pulses per 1 revolution
CN2-9 G/W Discharge temperature sensor
When discharge air temperature rises over the
emergency stop pre-determined temperature, it
makes emergency controller Ry4 relay ON and it
sends abnormality signal to ECU to stop engine.
●
