Assembly and connection manual | Agrónic 2500
In installations where there is a motor pump, the
Agrónic can manage the start and stop maneuvers. To
manage it, it uses four outputs (preheating, contact,
start and stop) and a digital input (oil pressure gage).
When making the connections for the diesel pumps,
the following details must be taken into account:
INPUTS
PA oil pressure gage. In the version for starting diesel
pumps, the pressure gage input function is assigned to
this input. The CD digital input common does not have
to be connected to the pressure gage as this is done
directly through the pump chassis.
OUTPUTS
The outputs deliver the battery positive. A supple-
mentary relay is intercalated between each to prevent
damage to the internal relays.
The contact output is connected through the relay to
the cable from the ‘15/54’ terminal of the valve. This
is the unit responsible for connecting and disconnect-
ing the contact, so the valve must be le in the inactive
position.
At the start-up output, a supplementary relay is inter-
calated with a capacity for 20 to 30 amperes, connect-
ing the output to the cable from the ‘50’ terminal on
the valve.
If the pump is stopped by an electromagnet, this is
connected to the supplementary relay from the stop
output.
