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:
undefined]
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 Amplifier temperature sensor
problem.
Replace amplifier.
02: A-EEPROM ERR Amplifier EEPROM problem.
02: CPU BOARD ERR Amplifier 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 Amplifier 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
specified range.
Continues to operate
and output.
