1 G/B
Discharge air temp. sensor
No.1 terminal
2 G/W
Discharge air temp. sensor
No.2 terminal
Detection of discharge air temperature.
It ignites controller surface warning: emergency stop
lamp at higher temperature than set one. Also when it
is higher than the emergency stop actuating set
temperature, interior contact (RY1) between CN1-4
and CN1-8 terminals will be turned “OFF” to make
engine emergency stop.

When auto idle (purge control) is switched “ON” to be
electrically connected, it will be switched to purge
control mode.

G
Engine oil pressure switch
It is electrically connected during normal operation.
When engine oil pressure drops, engine oil pressure
switch turns “OFF” to cut electrical connection. When
electrical connection is cut, interior contact (RY1)
between CN1-4 and CN1-8 terminal turns “OFF” to
cause emergency stop to engine.

Coolant temp. sensor No.2
terminal
Detection of engine coolant temperature.
When temperature exceeds the set temperature, it
ignites controller surface warning /emergency stop
lamp. Further, when the set temperature of
emergency stop becomes higher, the interior contact
(RY1) between CN1-4 and CN1-8 terminals turns
“OFF” to cause engine to emergency stop.
