Eclipse RatioMatic v3.10 - Design Guide No. 110, 12/01

The flame monitoring control system consists of two main

components:

• Flame Sensor

• Flame Monitoring Control

Flame Sensor

Two types can be used on a RatioMatic Burner:

• flame rod

• U.V. scanner

Flame rods are available for all RatioMatic Burner sizes. Further

information can be found in:

• Info Guide 832

A U.V. scanner can be used on all RatioMatic Burner sizes.

Further information can be found in:

• Info Guide 852; 90° U.V. scanner

• Info Guide 854; straight U.V. scanner

• Info Guide 856; self-check U.V. scanner

Flame Monitoring Control

The Flame Monitoring Control processes the signal from the

flame rod, or U.V. scanner, and controls the start-up sequence

and the main gas shut-off valve sequence.

Eclipse Combustion recommends the use of flame monitoring

control systems which maintain a spark for the entire trial for

ignition time when using U.V. scanners. Some of these flame

monitoring models are:

• Veri-Flame; see Bulletin / Info Guide 610, 620, 630

• Bi-Flame series; see Instruction Manual 826

• Multi-Flame series 6000; see Instruction Manual 820

DO NOT USE:

• PCI Automatic flame monitoring

• Honeywell RM7890 series flame monitoring

• Flame monitoring relays which interrupt the trial for ignition

when the flame is detected.

• Flame sensors which supply a weak signal.

• Flame monitoring relays with low sensitivity.
