Features:
  • For signaling flame

  • operation in conjunction with automatic burner control IFS 110 IM
  • UV-detector or ionization control with flame rod
  • Potential free contacts
  • Integrated ‘‘ON’’ lamp
  • FM approved
  • Kromschröder is a company certified to ISO 9001

Application:
  • To detect and signal an existing flame using flame rod or UV-detector.
  • Used for multiburner control together with the IFS 110 IM automatic burner control or wherever a fully automatic control is not required.

Function Description:
  • The flame relay is immediately operational once the operating voltage is applied.
  • When a flame is present, the active dc signal switches relay B.
  • Depending on the application at hand, the contacts of this relay B can be used for control functions.

Multi-burner Control:
  • Theoretically, there is no limit to the number of burners which can be controlled.
  • There must be assurance, however, that all burners can be ignited within the trial for ignition period for the automatic burner control (3;5 or 10 sec).
  • Very long gas lines might result in delayed ignition of a burner and cause a shutdown of the entire system.
  • Experience demonstrates that a number of automatic burner controls should be used when systems with more than 10 burners are involved.
  • The flame signal feeder line to the automatic burner control is run via terminals 8 and 9 (normally open contact). The normally closed contact is connected to terminals 7 and 11 on the automatic control (see connection diagrams and terminal connection diagram).
  • In the flame monitored by an IFW 15 T-N goes out during operation, the flame signal to the automatic control is interrupted and all other burners are switched off within one second
  • If an outside light is detected before the ignition (simulation of a flame), the system goes to lockout.

Instructions for Planning of System:
  • Adhere to the following instructions when planning systems: Distance from burner to relay IFW 15 T-N and automatic burner control IFS 110 IM is max. 150 ft (50 m).
  • Use unshielded high-voltage cables for flame signal line. Keep them away from the ignition line and other sources of interfering radiation.
  • Maximum length of the ignition line is 15 ft (5 m), therefore install the ignition transformer near the burner.
  • During monitoring with a flame rod, a burner can be monitored by the automatic burner control IFS 110 IM (Fig. 3).

Accessories:
  • Diode GP 10Y
  • Order No. 0 401 2102 Highvoltage cable for ionization line and ignition line FZLSi 1/6 up to 350 °F (180 °C)
  • Order No. 0 425 0410.

Flame control with flame rod (Fig. 5):
  • An alternating voltage (220 V) is applied between the flame rod, which projects into the flame, and the grounded burner.
  • As soon as the flame is established a small current flows through it and is rectified by the flame.
  • The electronic amplifying stage detects only this direct current signal which, after amplification, is used to energize a relay.
  • A flame cannot be simulated.
  • The flame must touch the burner tube.
  • High voltage cable should be used as ionization line in order to avoid losses through insulation: FZLSi 1/6 order No. 0425 0410

Flame Detector Relays R4343D and R4343E are essentially switches which, when used with the appropriate sensors, can signal the presence or absence of a flame or ultraviolet (UV) light.

Features:
  • Flame current meter jack socket permits monitoring of flame signal strength.
  • Plug-in mounts onto a subbase for surface mounting
  • A jack en face avant permet la mesure du courant de flamme.
  • The flame current measurement socket allows direct control of the flame signal intensity.
  • Plug-in sleeve mounts on a sub-base (the container that meets the requirements

Mount relay on the subbase:
  • Plug the relay into the subbase.
  • Secure the relay to the subbase by tightening the two captive screws on the relay face.
  • When the installation is completed, check the flame current value as described below.

Check the points on this list before starting the system:
  • That system overload protection is correct.
  • That wiring connections are correct and that all terminal screws are tight
  • That the flame detector is correctly installed and that the correct flame detector is being used.
  • That the burner is completely purged and ready to fire with the fuel lines purged of air
  • That the combustion chamber and flues are clear of fuel
  • That power is on at the system main switch.

Flame Detector Checkout:
  • The performance of the relay depends upon how well the flame detector is installed.
  • For guidance on how to properly install a flame detector, consult the burner/boiler manufacturer’s instructions and the information packed with the detector.

Flame current check:
  • The test jack on the face of the relay allows the value of the flame current to be easily measured.
  • Use a Honeywell W136A microammeter (or equivalent), which has a plug for insertion into the test jack socket.
  • The expected maximum and minimum values of flame current for the various types of flame detectors are given in the table below together with hints on what to check if the current is unsteady or weak.

Installation of the flame guard:
  • Switch off the supply voltage before attaching the flame detector to the base.
  • Push the flame detector into the socket until it stops.
  • Check the flame detector for tightness and both
  • Tighten fixing screws evenly

Before starting the system, check the following:
  • Is the overload protection correct?
  • Are the connections correct and all terminal screws tightened
  • Is the flame detector suitable for the relay and is it correctly installed
  • Has the burner been completely purged and the oil pipes purged of air
  • Has the combustion chamber and the ducts been purged of all fuel oil
  • Is mains voltage present at the main switch
