3. MANU Function Test

3.1 Select to SW1 in drawing1 ∴5X is running through 12X

, 26WX, 63QX, "b"contact point of EPS.

solenoid(5S) is running through voltage output of STP terminal

(ETR TYPE) 88X is running through 14X"b"contact point

(No running oil press switch of 63QY"a"contact point)

Constituted starting circuit through voltage output of SST

terminal

▶"a"contact point function of 63QY- started engine&increased

oil press Prevented interception of starting circuit

▶SS1&SS2 terminal starting signal input- running of 14X

(600±500RPM)STT output interception through 88X off

Running stop through double interception of starting circuit

3.2 .Automatic starting PUN LED of E.C.U. by engine starting

signal input

After automatic starting PUN LED, 63Q(oil press switch) must

open within 7sec.

3.3 Engine stop

▶ETS(ENERGIZED TO STOP): In case of stop, fuel line closes.

▶ETR(ENERGIZED TO RUN): In case of start, fuel line opens.

ETR: 5X off by SW1 off ∴ interception voltage of STP Fuel

line 5S off ∴ engine stop

ETS: STP voltage output for ≒15sec. by SW1 off Feul line

5S on ∴engine stop, 5X off
