11. DIESEL OPTION ANNEX
This option increases the functions of the AGRÓNIC 2500 by providing control over the internal combustion
motor (diesel or gasoline) with an electric starter.
The operational theory is the following: when the first irrigation program is about to begin (related to Pump 1),
the corresponding irrigation sector activates and, after the waterhammer temporization has elapsed, the contact
output is activated, as is the preheating output, if applicable. When this has finished, the first start-up is attempted.
After 30 seconds have passed since the first attempt, if the equipment detects oil pressure, it will consider the
attempts have been successful. If this time has passed and there is no pressure, the equipment will try to start-up
the motor again, and so on until a total of 4 is reached. If 4 attempts have been made and there is still no pressure,
it activates the pump stop and it triggers a “start-up error”.
READINGS
Description of each type of anomaly: ( [N xx] = Number related on the events table )

Diesel Motor, oil pressure found [N30]
When irrigation starts, the equipment tries to activate the diesel motor
and it finds there already is oil pressure, which in theory means that
the motor is running. In this case an anomaly is recorded and irriga-
tion and motor control continues without making any more start-up at-
tempts.
 Diesel Motor, does not start [N31]
Once the four start-up attempts have been made and 30 seconds
have passed, if the motor is not operating, the programs under way
that contain the sectors related to motor 1 will be terminated.

Diesel Motor, oil pressure error [N32]
When a loss of pressure in the cylinder head is detected when the mo-
tor is operating, a record of the anomaly is made and the sectors be-
ing irrigated related to pump 1 are stopped.
CONSULTATION
The general consultation informs us on the status of the diesel motor or generator; the status of the oil pres-
sure gauge is indicated on the last line of the first screen of digital sensors. The second screen shows the status of
the diesel.
