Switch In The Off Position 1

Switch In The On Position Start button S1 position 1: Line 2 on 12V contact K3 closed (30-87), lamp H2 is on. K4 excites contact K4 (87-87a). Thermocontact element S5 normally closed, K1 excites contact K1 (30-87). 2

Switch In The On Position S-4 Cold Start Pressed Use of preheat: Start button S1 position 1 press pushbutton S4, energizes relay K5 and provides power to the glowplug. 3

Switch In The # 2 Position Start button S1 position 2: Line 3 on 12V (override function) hourmeter P1, and fuel solenoid Y1 is excited. Thermocontact engine S2 normally closed, oil pressure contact S3 open. 4

Switch In The Start Position Start button S1 position 3: Start relay K0 is excited and starter motor is running, engine builds up oil pressure and oil pressure contact S3 closes. K3 excited and contact K3 changes over to (30-87). Relay K2 no longer excited, contact K2 opens, lamp H1 goes out. Alternator also commences supplying voltage and K4 is no longer excited and contact K4 changes over to (87-87a). Lamp H2 goes out, one can release start button S1 and it returns to position 1. Exciting the safety devices occurs no longer across line 3 but across line 2 to line 4 and this way to line 3. 5

Switch Back To The On Position- Engine Running Explanation of shutdowns: Oil pressure contact S3 opens, K3 no longer excited. K3 changes over (87a-87), 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 (87a-87), 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 (87-87a). K3 no longer excited. K3 changes over (97a-87), 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 (87-87a). 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 (87a- 87), engine cuts out because fuel solenoid Y1 no longer excited and lamp H2 goes on simultaneously. 6
