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:

undened]

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 Amplier temperature sensor

problem.

Replace amplier.

02: A-EEPROM ERR Amplier EEPROM problem.

02: CPU BOARD ERR Amplier 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

13: AT OVER SPEC Amplier 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

specied range.

Continues to operate

and output.

AL. 35
