Introduction
This section describes the features of the Veri-Flame. It is
divided into three categories: standard features, optional
features and the LED indicator lights on the front cover.
Refer to Figure 5.5 for sequence diagrams.
Standard Features
The following function features are standard on the Veri-
Flame models as noted:
Interlocks and Limit Switch Input (Terminal 7)
This input is considered the normal operation control or
run input to the Veri-Flame system. Interlocks are
generally pressure or temperature switches which, when
activated, start the burner. Limit switches are generally
pressure, temperature and other switches which, when
activated, stop the burner. The interlocks and limit
switches are wired in series. A break in this circuit will shut
the burner down, but will not produce an alarm.
Combustion Air Switch Input (Terminal 6)
For purge and modulation models: This input is for
monitoring the combustion air switch separately from
other interlocks and limits. The Veri-Flame checks the air
flow switch input is open before start-up, closed during
operation, and open again at burner shutdown, thus
preventing operation with an air switch that is defective,
maladjusted or jumped. This input has about a 2 second
delay to filter out and ignore a momentary interruption.
The input will be proven open before start-up and after
shutdown.
If the input is improperly powered before the fan output is
energized, the system error light will blink. The input must
de-energize within 30 seconds or the Veri-Flame will
lockout.
After the fan output has energized, the air switch input
must be made within 10 seconds. If not proven, then the
system will lockout, the alarm output and the air failure
light will come on. However, if the unit has the optional air
switch input hold feature, the sequence is held indefinitely
without causing a lockout. When the air switch input is
made, then the sequence continues.
If the air switch opens during the main firing cycle, the
system will either lockout or recycle, depending on the
DIP switch recycle selection.
Main Fuel Valve Closed Switch (Terminal V)
For purge and no-purge models: The Veri-Flame can be
interlocked with the main valve closed switch. This feature
checks the switch position before start-up and after
shutdown to insure proper valve operation when the
jumper on the base is cut.
Low Fire Start
For modulation models: When wired, the system checks
for the low fire start position prior to light-off.
Main Fuel Valve Closed / High Fire Purge Check
(Terminal D)
For modulation models: This feature is enabled when the
jumper on the base is cut. The system checks that the
high fire position switch and the main valve closed switch
are both made at the end of the high fire purge.
Recycle Mode
For all models: When selected, the Veri-Flame will restart
the sequence after flame or air failure. The recycle mode
allows the system to re-initiate the start-up sequence
automatically
provided the main burner has been
operating for at least 35 seconds
. If the pilot flame fails to
light during recycling, the system will lock out and
annunciate a pilot flame fail. If the recycle is successful
and the main burner is operational for at least 35 seconds,
the system is ready for another recycle. At no time will the
system recycle in the event of pilot flame fail.
