AL. 01
CAP. ERR
Sensor problem. Outputs the signal (Hold, High, or
Low) set with parameter.
Replace capsule when error
keeps appearing even after
restart.

AL. 10
PRESS
Input is outside measurement
range limit of capsule.
Outputs high range limit value or
low range limit value.
Check input or replace capsule
when necessary.
AL. 11
ST. PRSS
Static pressure exceeds limit. Continues to operate and output.
AL. 12
CAP. TMP
Capsule temperature is outside
range (–50 to 130°C).
Use heat insulation or make
lagging to keep temperature
within range.
