The
Knight Watchman is a self-contained, proof of flame, direct
spark ignition system. Upon a call for heat, input power from
your 120V or 24V AC input device, (i.e., micro-switch, proximity
switch, photoelectric sensors, etc. ) is applied to the control
board. The control system then initiates sparking and your
electric gas valve is energized. Sparking continues with the
gas valve powered for a specified period. In normal operation,
as soon as flame is established and proven by the flame sensing
circuitry, sparking will cease immediately and the system will
remain on, monitoring the flame until the end of the duty cycle.
Should a flame-out occur during the duty cycle, the system
will reactivate the spark within 0.8 seconds, to provide for
re-ignition. The flame will either be re-established within
the specified time, or the system will lock-out in the normal
manner. Should lock-out occur, reset action must be taken before
the unit can be recycled. In this case, the gas solenoid will
be shut off and an alarm horn will sound alerting the operator.
There are Indicator Lights and second party Terminals, inside
the Control Panel, to indicate the status of the system,
Reset Push
Buttons, Fusing, Horn Signals, E-Stop, Test Push Buttons for
set-up, etc. If there was a general loss of power,
the system will not
restart upon the resumption of power, it must be manually re-started. APPLICATIONS
- Plastic
Flame Treating
- Conveyor
Belt Warming for glass processing applications
- Monitoring
Pilot Flames for automatic cycling Gas/Air or Gas/Oxygen
Burner applications
- Any
Open Flame Gas/Air Burner application that has Flame Safety
or Process Critical concerns
OPTIONS
- Knight
Gas/Air Burners, Electric Fuel Valves, Combustion Mixers,
and Precision Needle Valves are made for many Industrial
applications including Plastic Flame Treating
- KNIGHT
Combustion Control Panels are self-contained Panels that
contain Flow Meters, Precision Needle Valves for precise
set-up of the combustion process, Manual Shut-off Valves
and Electric Solenoid Fuel Valves
- The
above two items when ordered with a KNIGHT WATCHMAN make
a complete system that can simply be attached to your existing
process or an entire process can be designed for your specific
needs
