RAM data abnormality (See Note)
0; RAM and non-volatile memory
data coincide.
1: RAM and non-volatile memory
data do not coincide.
As the status data, the corresponding bits are set. For example, when alarm
output 1 is ON, the status data is 0200 (ASCII code - 30H, 32H, 30H, 30H).
For negative data values, x10
3
becomes F (e.g. --35
A
C = F035).
An A/D error requires E5AF/E5EF inspection.
When the E5AF/E5EF is underflowing, the process temperature will be the
lower limit value of the maximum input range. During overflowing or with sen-
sor error, the process temperature will be the upper limit value of the maxi-
mum input range. Check the status data for the proper operation of the
E5AF/E5EF.
For the Heater Burnout Detection Models, alarm output 1 bit is used as the
alarm bit. Alarm output 2 bit is for the detection of heater burnout and abnor-
mal input.
For the Heater Burnout Models, the input shift bit is 0.
