DESCRIPTION
The Fireye® BurnerLogix™ Z System expands on the standard BurnerLogix Y System (see bulletin
BL-1001) by combining boiler control functions with the same burner management control found in
the Y system. The result is a single compact package that can directly control the boiler's output fir-
ing rate based on either input pressure or temperature or both. The BurnerLogix Z System is
designed to provide the proper burner sequencing, ignition and flame monitoring protection on auto-
matically ignited oil, gas, and combination fuel burners. Through the display, the operator programs
the desired setpoint, cut in, cut out and modulating range and with PID control, the BurnerLogix Z
System controls the burner/boiler from start up through shutdown, precisely maintaining the desired
setpoint. The BurnerLogix Z System continuously monitors interlocks and limits found in the L1-3
and 3-P circuits as it programs the burner/blower motor, ignition and fuel valves to provide for
proper and safe burner operation. VFD and LCD displays are available that may be either plugged in
or mounted remotely to give full language descriptors of current status and diagnostic lockout infor-
mation as well as provide a user friendly menu system to make setting the boiler parameters easy and
understandable. When mounted remotely, the displays provide NEMA 4x(IP66) protection. Through
SMART LED'S, located on the front cover or through the display interface, the control provides cur-
rent operating status and lockout information in the event of a safety shutdown. Following are some
of the major control and monitor capabilities provided by the BurnerLogix Z System:
•
Operating Control Function
for automatic sequencing of the boiler system to start and stop the
boiler to meet system demand.
•
Full Modulation Control
of fuel and combustion air through the firing rate motor to meet sys-
tem demand.
•
Solid State Sensors
to monitor steam pressure, water temperature, stack temperature, boiler
water temperature, or outdoor air temperature.
•
High Pressure and Temperature Alarm Limits
based on inputs from solid state sensors.
Exceeded limits will open interlock circuit to the flame safeguard control for shutdown of the
burner and boiler.
•
Cold Start Thermal Shock Protection
to slowly increase the burner firing rate on a cold start
to limit mechanical stress due to thermal differences.
•
Multiple Lead/Lag
operation of two or more boilers.
•
User-friendly keypad display system
in either VFD or LCD format featuring the all-info dis-
play mode, program and review of system setpoints and operating parameters.
•
Remote Communication Capability
allows reading and writing of all setpoint information.
•
Password Protected Parameters
(two levels of security) to restrict unauthorized entry and
modification of system setpoints and operating parameters.
