NOVUS N1500G - Manual (Page 5)

Indicator N1500G
NOVUS AUTOMATION 5/5
Dois parâmetros devem ser configurados para utilização da interface
de comunicação serial: o Baud-Rate de Comunicação (parâmetro
bavd
bavd bavd bavd) e o Endereço de Comunicação (parâmetro adres adres adres adres).
RS485 INTERFACE: ELECTRICAL CONNECTION
The RS-485 signals are: D1 = D: Bidirectional data line
D0 =
D:
Inverted bidirectional data line
C = GND: Optional connection. Improves
communication performance for
long cable runs.
9. PROBLEMS WITH THE INDICATOR
Connection errors or improper configuration will result in
malfunctioning of the indicator. Carefully revise all cable connections
and programming parameters before operating the unit.
Some error messages will help the user identify possible problems.
Message Possible Problem
Measured value is above the programmed
sensor or input signal limit.
Measured value is below the programmed sensor
or input signal limit.
Open input. No sensor is connected or the
sensor is broken.
Pt100 cable resistance is too high or the sensor
is badly connected.
Different messages other than the ones above should be reported to
the manufacturer. Please inform the serial number if this should
occur. the serial number can be viewed at the display by pressing the
BACK key for about 3 seconds.
The software version of the instrument can be viewed at the time the
unit is powered. The instrument might display false error messages
when wrongly programmed or when connected to a sensor for which
it was not programmed.
