5. SERVICING
The transmitter is equipped with a 8x2 characters display field with
backlight and one capacitive button located on the transmitter housing.
After connecting wires, closing and servicing the housing, and connecting
to the supply, the transducer is ready to work with manufacturer’s settings
(table 8).
The transducer can be programmed through the RS-485 interface.
One can program following parameters in the transducer:
- communication parameters
- averaging time of the measurement,
- individual characteristics of analog outputs
(for executions with analog outputs).
There is the possibility to connect the transducer through another trans-
mission media, like:
ETHERNET, USB,
using LUMEL S.A.’s converters.
5.1. Messages after supply switching on
After connecting external signals and switching the supply on,
the transducer displays the type, the current software version, serial number
and set the communication parameters (address, baud rate and mode).
After about 5 seconds, the transducer automatically switches to the
mode in which it measures and converts into the analog output signal.
The transducer displays the measured value with the unit on the bottom
row of the display, on the top row of the display contains information about
the type of displayed value and pictograms: of transmission on RS-485
link, the mode of presentation of the measured value and the ratio of the
measured value read from the sensor.
