DESCRIPTION OF FUNCTIONS OF OPERATING CONTROLS
1.
Operating Controls:
Generally pressure or temperature activated, the operating control closes,
causing the burner start-up sequence to begin. When the operating control opens, the burner
shuts off. The operating control is connected in the L1-3 circuit on the wiring base.
2.
Limit Switches:
These are generally pressure, water level or temperature activated
a. Recycle — when it is desired to stop the burner when the limit switch opens and restart it
when the limit switch recloses, they are connected between Terminals L1 and 3.
b. Non-Recycle —when it is necessary to stop the burner when the limit switch opens and pre-
vent it from starting until both the limit switch recloses and the manual reset is activated, they
are connected between terminals 3 and P.
3.
Fuel Valve End Switch Interlock
: This is generally an integral switch mounted on the main
fuel valve and activated by the valve stem. It is connected between Terminal L1 & 13. The fuel
valve end switch interlock prevents a burner start-up if the valve stem is not in the “valve
closed” position. This interlock must remain closed while in STANDBY and until the start of
PTFI.
4.
Purge Interlock:
Generally a firing rate motor linkage position switch or a differential air-pres-
sure switch, that proves a maximum purge air flow rate. It is connected between Terminals M
and 8. The purge interlock proves that the air damper is fully open and purge air flow rate is at
maximum during the purge.
5.
Running Interlocks:
These generally are air flow switches, high and low fuel pressure
switches, oil temperature switches, atomizing media pressure switches, and excess smoke den-
sity controls. These interlocks prove proper conditions for normal operation of the burner. They
are wired in series and connected between Terminals 3 and P.
6.
Low Fire Start Interlock:
Generally a firing rate motor linkage position switch or a damper
position switch, will prove both the linkage and dampers are in their proper positions to begin
burner light off. This switch is connected between Terminals M and D.
SETTING PROGRAMMER PARAMETERS
In order to change the factory default parameters stored in the programmer module an optional key-
pad/display (BLV512 or BLL510) is required. All configurable parameters are stored within the
PROGRAM SETUP sub-menu. The keypad/display module provides tactile feedback keys that are
used to access the sub-menus inherent in the BurnerLogix system.
The BurnerLogix display consists of 2 lines having 16 characters per line. The default displayed item
is the current operating status. This would include the current point in the burner sequence followed
by the parameter pertaining to that point in the sequence, such as time or the flame signal level. The
bottom line is used to display the current operating status. The BurnerLogix display also provides the
historical information stored in the control’s memory such as burner hours, cycles, lockouts and sys-
tem hours. The remainder of the display items are menus with sub-menus indicated by a right facing
arrow. The sub-menus indicate the current value of the selected item and in some cases can be modi-
fied to suit the application.
All programmed settings become permanent after 8 hours of main burner (Terminal 7) on time.
