95DS InSight Flame Scanners 95IR_95UV_95DS
The InSight probe detects the modulated amplitude generated by the target flame (and the flicker characteristics of the flame). In the probe setup program, will
The modulation frequency is selected, and this value directly affects the best flame recognition capability (ON/OFF value). And can be set manually Set (type S1) or override manual setting to automatically set (type S2) to select the appropriate modulation frequency and probe gain.
After selecting the appropriate flicker frequency, enter the ON/OFF threshold value of the flame relay. (This option is automatically set in the S2 model Set). In the signal strength output of 4-20mA, the minimum value (4mA) represents the signal strength of “0” and the maximum value (20mA). Indicates that the signal strength is 100.
The flame relay is energized when the signal strength reaches or exceeds the threshold value of the flame “ON” that has been set (normally open contact) Closed). When the signal strength reaches and is lower than the set flame “OFF” threshold value, the relay loses power (close the contact to play On). The closing contact also opens when the power supply is interrupted or when an internal fault is detected. (See below)
The fault relay is energized when the probe is powered properly (24 Vdc) and the probe interior is correct through self-testing. When power supply Loss of power when interrupted or internal fault is detected. A normally open contact signal (from the fault relay) is connected in series to the flame relay In the loop, a normally closed contact signal is used for alarm display.
