6.3 Configuration
In the system menu the parameters are divided into 5 groups: LvoP , iniT , Adv , Comm
and LmAn (Fig. 6.3).
The full list of the programmable parameters is given in Table B.1.
The parameters are saved in the memory registers according to the Table C.3.
Fig. 6.3 Parameter groups
–
LvoP – operation parameters (Process value, Setpoint, Current output signal,
Remote Start/Stop, Autotuning), displayed at the device start
–
init – basic settings
– Adv – advanced settings / LBA
–
Comm – RS485 network settings
– LmAn – Manual control settings
To use the functional keys in Configuration refer to Table 6.3.
6.4 Temperature sensor
The signal from the resistance thermometer or thermocouple is converted according to
the sensor curve for the selected sensor. The type of the connected sensor should be set
in the
parameter in-t (Sensor).
When the RTD or TC is used, the displayed accuracy for the measured temperature can
be set in the parameter
dPt (Decimal point displayed). The parameter is not available in
the menu for sensors with the linear output. For the thermocouples with the upper limit
above 1000°C is recommended to set
dPt = 1, for other temperature sensors dPt = 0.
When the thermocouple is used, Cold junction compensation (CJC) enables precise tem-
perature measurement. The reference junction sensor is located near the input terminals.
The function is active by default. It should be deactivated only during the calibration. Set
the parameter
wXC (Calibration parameters) to OFF to disable this function.
6.5 Linear signal
There are additional functions for linear signal processing: decimal point position and
scaling.
When a linear sensor is used, the accuracy can be set in the parameter dP (Decimal
point). For temperature sensors the parameter dP = 1 and is not available in the menu.
Note : The parameter dP affects other parameters (see Table B.1).
The measurement range can be defined in the parameters:
in-L – signal lower limit
in-H – signal upper limit
