Parameters of Commands and Responses

*5

The data number “008” can be read to check the error status of the sensor amplifiers.
Convert the five digit number (ASCII characters) read from the sensor amplifiers to a binary
number and check the ON/OFF state of each bit to
check the error contents.

For information on each error, refer to "FD-S Series User's Manual".

• When the data read from a sensor amplifier is "1056":

"1056" converted to binary number is "0000 0100 0010 0000".

Therefore, this data indicates that the "temperature low error" and the "reverse
current error" have occurred at the same time on the sensor amplifier from which the
data was read.

• If no error has occurred at the sensor amplifier, the data "0000" is returned.

*6

When the data falls below 0, this indicates "-999.9", and when the data exceeds 99.9, this
indicates "+999.9".
