2、System operation status
The system operation status screen is shown below:
Brief description of the working process:
When the system is in operation, the keypad is locked, the "Run" lamp lights up, the system dynamically detects and displays the flame intensity as well as the fire threshold.
The system dynamically detects and displays the flame intensity and the fire threshold.
When the flame is effective (flame intensity > fire threshold) and the duration exceeds the fire delay time, "Flame" lamp lights, flame relay output is effective (normally open contact closed).
When the flame is effective (flame intensity > fire threshold and the duration exceeds the fire delay time, the "flame" lamp lights up, the flame relay output is effective (normally open contact is closed), the current output is the corresponding value (4mA-20mA DC), and the system starts the self-checking function automatically according to the time to be set.
When the self-test time arrives, the "self-test" lamp lights up, and at the same time detects whether the probe, the system interface is normal and whether the system is over-temperature or not, when the system fails or the system is over-temperature, the "self-test" lamp lights up.
When the system is faulty or the system is over-temperature, the "Alarm" lamp lights up, the alarm relay output is effective (normally open and closed, normally closed and open), and the system remembers the type of alarm. The system remembers the alarm type.
The system reopens by pressing the "Function" key 2 times continuously.
In the flame effective running state ("running", "flame" lamp is lit), press the "OK" key, then the manual self-test function, the system manual self-test mechanism and automatic self-test.
The mechanism of self-test is the same as that of automatic self-test.
When the flame is invalid (flame intensity < no fire threshold) and the duration exceeds the flame failure response time, the "flame" lamp goes out, the flame relay output is invalid, and the current output is in line with the intensity.
When the flame is invalid (flame intensity <no flame threshold and duration exceeds the flame out response time), the "flame" lamp goes out, the flame relay output is invalid, the current output is the value corresponding to the intensity (4mA-20mA DC), and the self-test function stops.
In the flame invalid operation state ("operation" lamp lit, "flame" lamp off), press the "OK" key, artificial self-test function is invalid.
When the external wiring (12-pole) terminal No. 9, No. 10 line shorted, the system for the masking function - forced to no fire state: no flame switch effective output, current output and intensity of the
Switch effective output, current output and intensity of the corresponding value (4mA ~ 20mA DC), flame lamp out. The system alarm function is normal.
