Thermocouple/Millivolt Input Module 9
4#,*$"3*/. 9 $3/#&1
If a write block of five words with all zeroes is sent to the module,
default selections will be:
• Millivolt input
• one input type
• temperature in
o
C
• BCD data format
• no real time sampling (RTS) (50ms)
• no alarming
The front panel of the thermocouple/mV input module contains a
green RUN indicator and a red FAULT indicator. At power-up, the
module momentarily turns on the red indicator as a lamp test, then
checks for:
• correct RAM operation
• EPROM operation
• EEPROM operation
• a valid write block transfer with configuration data
If there is no fault, the red indicator turns off.
Thereafter, the module lights the green RUN indicator when
operating without fault, or lights the red FAULT indicator when it
detects fault conditions. If the red FAULT indicator is on, block
transfers will be inhibited.
Possible module fault causes and corrective action is described in
the following table.
