APPLICATION

The S7999B System Display reduces burner/boiler setup time

by letting you create a fuel/air modulation curve (profile) for

ControLinks™ that allows for safe and efficient operation at all

points along the modulation curve. The display uses a wizard-

like process to assist you through the commissioning process.

The S7999B can be used on systems with one or two fuels

and on systems with or without flue gas re-circulation (FGR).

The S7999B can monitor a single (Local) burner/boiler system

or up to 99 burner/boiler systems connected via System

Modbus™ network. Each burner control, fuel/air ratio control,

and expanded annunciator present on each burner system

can be viewed individually to determine its status.

Universal Digital Controllers (UDC) can be used for several

burner/boiler applications, and the S7999B can control the

UDCs during their operation. Applications supported include:

• stack temperature

• water/steam PID load control

• steam/fuel flow monitoring

• thermal shock

• feed pump level control
