The SEU (Sensor Unit) should be placed in a room where -the CO2 is likely to accumulate or 02 reduce, such as a room where CO2 is stored, like an area with CO2 beverages. The large LCD displays the ambient CO2 & 02 concentration.
The SEU has the 'DIAG", 'AL1", 'AL2"'CALI', 'ReFactSet' function. The "DIAG" function executes communication tests between the SEU and RDU. The user can do the calibration under the "CALI' mode when necessary. If data-setting is done incorrectly, the user can use the 'ReFactSet" back to the original factory setting.
There have 'AL1' 'AL2' two alarm levels, the alarm level is adjustable, the first alarm level of CO2 is with parameter 5000ppm, 1%, 1.5%, 2%, the default first
alarm level is 1.5%; the first alarm level of 02 is with parameter 18%,18.5%,19%,19.5%,20%, the default first alarm level is 19%.The second alarm level of CO2 is with parameter 1.5%, 2%, 2.5%, 3%, 3.5%, 4%, the default second alarm level is 3%; the second alarm level of 02 is with parameter 16%,16.5%;17%,17.5%,18%, the default second alarm level is 17%.
When the </wll CO2 &02 Monitor detects CO2 concentration exceeds the first alarm level or 02 concentration drops the first alarm level, the red 1 LED will blink the relay will be triggered. When CO2 concentration drops the first alarm level, or 02 concentration rise to the first alarm level, the red 1 LED will stop blinking.
If the concentration of CO2 continues to rise above the second alarm level, or the concentration of 02 drops the second alarm level, the red 1 and red 2 LED's will flash together. When CO2 concentration drops below the second alarm level, even to the first alarm level, the red 1 and red 2 lED's will remain blinking (This function is latch design. Based on DIN66532- ). Unless the ZGa21 is restarted, by means of reset button of c/y1 ii or unplug the AC adapter and reconnected it.
The green LED will light continuously when the power is_normally supplied.
Warning: If the ambient CO2 concentration reaches the second alarm level on SEU & RDU, there will be a safety notice "ESC' displays on the LCD, Careful action, such as ventilating the space, must be taken before entering the room where the SEU is placed.
If the communication cable between the SEU & RDU doesn't connect well, like the communication cable looses in the Input port, the fault LED of SEU will blink, reconnect the cable, if the cable is inserted into the output port, on RDU, after one minute, the 'Er7" will flash on LCD. Unplug the cable and plug it into the Input port. The unit will work normal! after corrective action.
