For “+” ignition coil cylinder-1: Terminal 1 (Channel_1);
For “+” ignition coil cylinder-2: Terminal 2 (Channel_2);
For “+” ignition coil cylinder-3: Terminal 3 (Channel_3);
For “+” ignition coil cylinder-4: Terminal 6 (Channel_4);
For “+” ignition coil cylinder-5: Terminal 5 (Channel_5);
For “+” ignition coil cylinder-6: Terminal 4 (Channel_6);
For “+” ignition coil cylinder-7: Terminal 8 (Channel_7);
For “+” ignition coil cylinder-8: Terminal 7 (Channel_8);
For “+” ignition coil cylinder-9: Terminal 13 (Channel_9);
For “+” ignition coil cylinder-10: Terminal 12 (Channel_10);
For “+” ignition coil cylinder-11: Terminal 11 (Channel_11);
For “+” ignition coil cylinder-12: Terminal 10 (Channel_12);
For “+” ignition coil cylinder-13 Terminal 15 (Channel_13);
For “+” ignition coil cylinder-14: Terminal 14 (Channel_14);
For “+” ignition coil cylinder-15: Terminal 16 (Channel_15);
For “+” ignition coil cylinder-16: Terminal 17 (Channel_16);
For “-” ignition coils at cylinder-bank A (left), to connect to rail-constr. and engine ground:
Terminals 23, 24, 25 (JL);
For “-” ignition coils at cylinder-bank B (right), to connect to rail-constr. and engine ground:
Terminal 9, 21, 22 (JR);
For emergency shutdown input “Ignition Stop”
(to switch “J” and “G”-wires by external relay-contact for stop of ignition):
Terminal 20 (engine ground “J”), Terminal 20 (shutdown wire “G”)
Not used terminals: Terminal 17 (not connected).
Terminals for output to ignition coils on the ignition rails to drive up to 16 cylinders by com-
bustion engine.
The function of diagnostics of sparking process by each cylinder and supervisoring of func-
tionality are included:
● output connector (output cable harness) isn’t connected shutdown of ignition;
● opening of primary ignition circuit (failure of ECU, cable or coil );
● short circuit of primary ignition circuit (failure of ECU, cable or coil );
● opening of secondary ignition circuit
(failure of coil, HV-wire, spark plug connector or spark plug );
● short circuit of secondary ignition circuit
(failure of coil or spark plug );
● spark duration diagnostic:
► spark duration to long (failure of coil, HV-wire, spark plug connector or spark plug);
► spark duration to short (failure of coil, HV-wire, spark plug connector or spark plug);
Additionally – one emergency shutdown input for activation by external relay-contact.
Short circuit between wires “J” and “G” provide stop of ignition process (shutdown) and turn
the ignition energy in store capacitor bank to zero.
The time-out after shutdown before continue of ignition-process: 250ms.
