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
