2.5 Set Sensor Type
1. Confirm that the correct SCM is installed and jumpered correctly:
a. For Non-Universal SCMs:
Confirm that each of the 16 hardware channels contains the correct SCM for the
intended application. For isolated thermocouple applications, a SCM is required.
b. For Universal SCMs:
Confirm that each of the 16 SCMs is configured for the intended application. For thermocouple
applications, a jumper must be installed in the small sockets on the top of the SCM. (See Figure
1-2).
Signal Conditioning Module (SCM).) For all other applications, no jumper is required.
2. Using Table 1 (on the next page), determine the value for each desired sensor type.
3. Using NUSS configure each channel using a command of the format:
vxxx51 yy, where
xxx ranges from 001 through 010 HEX for channels 1 through 16, yy is the sensor type
value determined from Table 1.
Examples
:
•
v00a51 18 will set channel 10 to a type T thermocouple.
•
V00951 60 will set channel 9 to an RTD with an ANSI 385 curve.
4. Send a
w07 command to write these values to non-volatile ROM.
Note
When the ‘v’ command is issued to set the sensor type for a
channel, the zero and offset coefficients for the channel are re-
initialized to the default values of 0.0 and 1.0 respectively.
