WARNING: Selection of this control for a particular application should be made by a
competent professional, licensed by a state or other government. Inappropriate application
of this product could result in an unsafe condition hazardous to life and property.
The Fireye SBSeries Flame Safeguard Control is a compact, microprocessor based, modular
burner management system designed to provide automatic ignition and continuous flame
monitoring for com-mercial sizes of heating and process equipment firing any type of fuel.
The SBSeries are tested to EN298.
The control unit includes all the necessary digital logic and analog measuring circuitry to control
the sequence and monitor the flame of single gas, oil or combination gas/oil burners. Three
available control sequences are no-purge, purge, and modulation (air damper control). The part
number specifies the various features such as the flame sensor type, no purge, purge, modulation,
proof of air opening at start, and timings; thus the designer has control and protection against field
tampering of critical sequences.
LED indicators are available on the front of the unit that provide current operating status of the
burner system including lockout alarm. A test jack is recessed into the front cover that provides
real time reading of the connected flame sensor. This same test jack is also used to connect to an
alpha-numeric display, SB20896. A push button provides reset from lockout condition as well as
placing the unit in a check condition usable for pilot turn down test.
The SBSeries flame safeguard control family are of plug-in design and available in models that
operate at 120 VAC, 50/60 Hz and 230 VAC, 50/60 Hz making them universally acceptable.
*The wiring base provides a convenient means for connecting field wiring from the burner and
valve system to the control unit. There are three styles of bases: an internal terminal base that
provides a guarded wiring compartment; an external terminal base for use within a protective
control panel; and an expanded external terminal base for use with the modulation sequence
control units.
Sensors that may be used with the SBSeries include flame rod (rectified ionization), ultra-violet
(UV) scanners, and self-checking UV scanners for continuous operation. Four types of non self-
checking UV scanners meet the demands of various environmental conditions.

Route the high voltage ignition wiring a sufficient distance from all sensors and other low voltage wiring to avoid electrical interference, which may cause erratic operation of the SBSeries system. Keep the high voltage wire as short as possible.

Page 19: Sensor Installation
SENSOR INSTALLATION WARNING: Incorrect sensor installation may cause the sensor to generate a false flame sig- nal, causing unburned fuel to collect in the combustion chamber. The result can be explo- sions, injuries and property damage. Be certain that the flame sensor detects only pilot and main flames, not glowing refractory, burner or ignition parts. - Page 20 Insert the positive probe of a 0-15 VDC, digital volt meter into the test point on the front cover of the SB Series control connect the negative probe to S2 or ground. A good flame signal strength will read between 6 and 11 VDC; anything below 4 VDC is inadequate. Also, the red LED inside the test point illuminates when a flame is indicated.
- Page 21 To enter the pilot test mode, depress the test/reset button located in the lower right corner on the front cover. To enter the pilot test mode, depress the test/reset button located in the lower right corner on the front cover. The control will hold the operating sequence at the pilot flame step.

Page 22: Maintenance
Maintenance Maintenance Preventative maintenance is the key to a reliable, safe and efficient system. The following are suggested guidelines for periodic maintenance. Burners in severe environments or operational conditions should be checked more frequently. The monthly and yearly lists are an average interval. If your environment is dirty, then the intervals may be shorter. -
