2.2. External electrical connection diagrams
The transducer has two sockets of terminal strips, which two plugs with
terminal screws are connected to. The way to connect external signals
is shown on the fig.2 on page 16.
The electrical connection diagram is also situated on the transducer
housing. In case of the transducer work in an environment with high
interferences, one must apply shielded wires in the transducer input.
3. SERVICE
After switching the transducer on, the work state diode should light in
red for a moment, next it should light in green.

Diode of the transducer work state:
- the state diode lights in green – normal
work,
- the state diode lights in red – improper work
parameters; one must configure the trans-
ducer again,
- the state diode pulsates in red – lack of
calibration or the non-volatile memory is
damaged; one must return the transducer to
the manufacturer.
Confirmation of the separator’s communication with PD14 programmer
is indicated by the status diode which turns off for short period of time.

The eCon software is destined for the P20 transducer configuration.
One must connect the PC computer through the PD14 programmer and
configure the connection choosing
Communication -> Serial port
from
the menu (for the P20 transducer, we choose the address 1, baud rate
9600 kb/s, the mode RTU 8N2 and the appropriate port COM under
which the controller of the PD14 programmer has been installed).
