5.4. INSTALLING THE OPTIONS
5.4.1. Diesel option
When making the connections for the diesel motor start-up version, the following details must be taken into
account:
INPUTS:
Oil pressure gauge OP. In the diesel starter version, the function of input of pressure gauge is automatically
connected to input 6. There is a delay of 10 seconds in the detection. The pressure gauge can only be connected
to this input. The CD digital input common does not have to be connected to the pressure gauge as this is done
directly through the chassis of the motor.
OUTPUTS:
The outputs charge the positive battery pole. A supplementary relay is intercalated between each to prevent
damage to the internal relays.
The contact output is connected through the relay to the wire from the “15/54” terminal of the key. This is the
equipment in charge of connecting and disconnecting the contact, so the key has to be left in the inactive posi-
tion.
At the start-up output, a supplementary relay is intercalated with a capacity for 30 to 30 amperes, connecting
the output to the wire from the “50” terminal on the key.
If the motor is stopped by an electromagnet, this is connected to the supplementary relay from the stop out-
put.
If the motor is stopped when the fuel supply is cut off by an electrovalve, this is installed at the same injector
input for the stoppage to be as quick as possible. When the electrovalve is normally open, it is connected directly
to the stop output. If the electrovalve is normally closed, it is connected to the contact output.
When there is a preheating function, this is connected to the relay to be activated.
For greater safety, it is convenient to have a double-stopping system that uses an electromagnet for stopping
quickly and effectively, plus an electrovalve that is normally closed so as to cut off the fuel supply in the event an
incident or malfunction.
