Setting range :
Display range :
0%~20%
0%~99.9%
Setting method : Press SET key twice.
Change to the desired value with key and key, then press ENT
key to store the value. Then the device shifts to the Overheat protection
temperature check mode.
Out of the range:
When a value is set out of the range and ENT key is pressed, buzzer
sounds 1 second (continuously) and the previous value is still remained.
Control : PID Control
Control OFF : When a value is set in 0.0%, CO
2
display will be disappeared to be the
Control OFF.
Alarm : When the internal CO
2
level deviates SV
±
1% or higher, CO
2
display
blinks. After the 15mininutes later, buzzer sounds and remote alarm
terminal turns ON.

Overheat protection temperature check mode
Setting range : 35

C
Setting method : Press SET key for three times to display the overheat protection
temperature on PV display and “HI” on CO
2
display.
Press SET key again to return to PV display.

Alarm, safety mode and self diagnosis
In sensors malfunctions and CO
2
control malfunctions, an error code and PV is displayed
alternately.
Note) The remote alarm is controlled in every a minute exceptionally in Auto Zero.
That’s why the remote alarm control is delayed 4minutes (max) after an error is
displayed.
<Error
code>
E01:

cylinder is empty
E05: Temp. sensor is open circuit
E06: Temp. sensor is short circuit
E07:

E08:

box temp. sensor is short circuit
E09: Ambient temperature sensor is open circuit
E10: Ambient temperature sensor is short circuit
E11:
CO

sensor output voltage is abnormal
E12: Main heater is abnormal
E13: Bottom heater is abnormal
E14: Door heater is abnormal
E15:
CO
2
sensor box heater is abnormal
E16: SSR for each heater is open circuit
E17: Sample pump and/or Auto zero pump malfunction
E18: UV lamp malfunction (a lamp blown out, a glow lamp unfitted, etc)
The description of error codes are follow:
E01 : CO
2
cylinder is empty
When the CO
2
level is not 0.2% or more in a minute even though the valve is
opened, “E01” and “Internal temperature “ are displayed alternately, and buzzer
sounds intermittently.
The definite action that CO
2
cylinder is empty, repeats twice, therefore it takes
approximately 2minutes to display an error after the cylinder would be emptied.
