FIRE-EYE
General Description
Fire-Eye is an electronic instrument preprogrammed with its outputs to suit the automatic working of gas burners. Fire-Eye basic function is to manage a safe start up of gas burner and continuously monitor the flame thereafter.
Fire-Eye is housed in an elegant plastic enclosure of 92 x 92 x 110 mm fitment. It can be directly mounted on the panel front door displaying the output signals through the LED display.
Principle of Working
Fire-Eye senses flame using flame rectification technique. The controller provides a voltage for the flame electrode. This flame electrode is immersed in the flame to be sensed. The current thus generated by the electron flow through the flame to the ground is detected by the Fire-Eye for the presence of flame.
Please note that a earth wire from the burner is to be connected to the Fire-Eye. The Flame electrode must be properly insulated while installing. Use HV cable for connecting the flame electrode and Fire-Eye to avoid any leakage sensing signal.
Terminations
Please connect the Fire-Eye as under.
· L – Phase through safety contact.
· N – Neutral
· P – Flame Probe.
· E – Burner Ground.
· B – Burner Fan
· I - Ignition
· V – Solenoid Valve
· A – Flame failure alarm.
Operation of Fire-Eye
All the connections are made as per the above details.
When supply is provided to Pin L, Fire-Eye will go through the following sequence of operations.
Burner fan [Terminal B] is switched ON for prepurging and a false flame check is done though any leakage current in the sensing circuit during absence of flame.
Ignition is energized after a delay of 7 secs .
Solenoid valve is switched ON with further delay of 4 secs.
There are two condition at this stage.
Condition A : The flame is established, sensed and is monitored continuously.Here the ignition goes OFF on receipt of Flame ON which is displayed separately through a blue luminuous LED.
Condition B : The flame is not established , all the output like burner fan , ignition , solenoid valve are de-energised and the unit goes into a lockout mode by energizing the flame failure alarm.
A retrial facility is also provided in the unit to ensure proper working of the burner.

GAS BURNER SEQUENCE CONTROLLER
Fire-Eye is an electronic instrument preprogrammed with its outputs to suit the automatic working of gas burners. Fire-Eye basic function is to manage a safe start up of gas burner and continuously monitor the flame thereafter.It provides output for blower, ignition,solenoid valves with prefixed timings with continuous flame supervision.Fire-Eye is housed in an elegant plastic enclosure of 92 x 92 x 110 mm fitment. It can be directly mounted on the panel front door displaying the output signals through the LED display.Fire-Eye senses flame using flame rectification technique. The controller provides a voltage for the flame electrode. This flame electrode is immersed in the flame to be sensed. The current thus generated by the electron flow through the flame to the ground is detected by the Fire-Eye for the presence of flame.It is widely used with Oven,Steam Boilers,Hot Air Generator,Furnaces, Incinerators,Process heating system,dryers and allied heating/drying systems.Company also manufactures oil burner sequence controller,photocells, ionization probes,UV cells and allied flame sensing devices.
