Engine is running normally:
Oil pressure contact S3 opens, K3 no longer excited.
K3 changes over (30-87a), engine cuts out because
fuel solenoid Y1 no longer excited and lamp H2 goes
on simultaneously.
Thermocontact S2 opens, K3 no longer excited. K3
changes over (30-87a), engine cuts out because fuel
solenoid Y1 no longer excited and lamp H2 goes on
simultaneously.
Thermocontact S5 opens, K1 no longer excited.
Contact K1 changes over (30-87a). K3 no longer
excited. K3 changes over (30-87a), engine cuts out
because fuel solenoid Y1 no longer excited and lamp
H2 and H1 go on simultaneously. Take-over relay K2
is excited simultaneously with H1 and contact K2
closes (30-87).
Thermocontact S5 cools off and closes, K1 excited
again and contact K1 changes over (30-87).
However, lamp H1 remains on across line 9 and
contact K2 (30-87).
A fault in the alternator part causes terminal D+ to go
to 0V and K4 to be excited. Contact K4 changes over
to (30-87), engine cuts out because fuel solenoid Y1
no longer excited and lamp H2 goes on
simultaneously.
N1 prevents the starter motor from being used when
the engine is running.
