4.1.2  Checking with Integral Indicator
NOTE
If an error is detected by running self-diagnostics, 
an error number is displayed on the integral 
indicator. If there is more than one error, the error 
number changes at three-second intervals.
See table 4.1 regarding the alarm codes.

AL. 01
CAP. ERR
01: P-SENSOR ERR Sensor problem. Outputs the signal  
(Hi or Low) set with 
parameter D26.
[Status output: 
undened]
Replace capsule when 
error keep appearing 
error even after restart.
01: CT-SENSOR ERR Capsule temperature sensor 
problem.
Replace capsule.
01: C-EEPROM ERR Capsule EEPROM problem.
AL. 02
AMP. ERR
02: AT-SENSOR ERR Amplier temperature sensor 
problem.
Replace amplier.
02: A-EEPROM ERR Amplier EEPROM problem.
02: CPU BOARD ERR Amplier problem.
AL. 10
PRESS
10: P OVER SPEC Input is outside measurement 
range limit of capsule.
Outputs upper range 
limit (URL) or lower 
range limit (LRL).
Check input or 
replace capsule when 
necessary.
AL. 11
ST. PRSS
11: SP OVER SPEC Static pressure exceeds limit. Continues to operate 
and output.
AL. 12
CAP. TMP
12: CT OVER SPEC Capsule temperature is outside 
range (–50 to 130°C).
Use heat insulation or 
make lagging to keep 
temperature within 
range.
AL. 13
AMP. TMP
13: AT OVER SPEC Amplier temperature is outside 
range (–50 to 95°C).
AL. 30
RANGE
30: P OVER RANGE Output is outside upper or 
lower range limit value.
Outputs upper range 
value (URV) or lower 
range value (LRV).
Check input and range 
setting, and change 
them as needed.
AL. 31
SP. RNG
31: SP OVER RANGE Static pressure exceeds 
specied range.
Continues to operate 
and output.
AL. 35
