Operation check after installation of MCO-21GC
(for MCO--20AIC/MCO-18AIC/MCO-18M/MCO-18AC)
After the installation of MCO-21GC is complete, check the operation according to the following procedures.
Procedures
1 Stop the gas supply from cylinder A and use only cylinder B.
2 Turn on the power switch of MCO-20AIC/18AIC/18AC and set 37 and 0%.
Check if the gas cylinder A is selected.
For MCO-20AIC/MCO-18AIC/18AC, check if CO
2
gas supply line indicator A lights.
For MCO-18M, check if the CO
2
gas supply line indicator lights.
3 Leave it for approx. 1 hour until the apparatus can control the CO
2
density.
(It may take approx. 1 hour to enable the apparatus to control CO
2
after the power is turned on.)
4 Set CO
2
in 5% and check if the CO
2
inject lamp turns on.
NOTE: In case of low ambient temperature, it may take more than 1 hour until the apparatus can
control CO
2
density and the CO
2
inject lamp lights.
5 Check if E01(CO
2
gas cylinder becomes empty) is displayed and buzzer sounds after 2-7minutes
later since the CO
2
inject lamp lights.
Check if the cylinder A is switched to the cylinder B.
For MCO-20AIC/MCO-18AIC/18AC, check if CO
2
gas supply line indicator A starts blinking and
the indicator B lights.
For MCO-18M, check if the CO2 gas supply line indicator starts blinking.
6 Check if the CO
2
density is displayed as 5% and keep it stabilized.
NOTE: When the decimal point blinks on the CO
2
display during CO
2
sensor calibration, CO
2
control may be interrupted.
7 After operation check is complete, shut down the CO
2
supply of cylinder A and cylinder B.
Press BUZZER key to eliminate the "E01" message.
Select the gas cylinder A.
For MCO-20AIC/MCO-18AIC/18AC, select the cylinder A by pressing CO
2
gas supply line
switching key.
For MCO-18M, press CO
2
gas supply line switching key during CO
2
density setting mode to
light CO
2
injection lamp.
Refer to the MCO-20AIC/18AIC/18M instruction manual for the usage of MCO-21GC
