S7999D1048 Combustion System
Operator Interface Display
APPLICATION
The S7999D Combustion System Operator Interface (OI)
reduces burner/boiler setup time by allowing the user to create
a fuel/air modulation curve (profile) for ControLinks
Air Ratio Control) that allows for safe and efficient operation at
all points along the modulation curve. The OI uses a wizard
like process to assist the user through the commissioning
process. The S7999D can be used on systems with one or
two fuels and on systems with or without flue gas re-
circulation (FGR). The S7999D has two RS485 com ports that
can be configured to provide:
• Fuel/Air Ratio Control commissioning and monitoring
• One or more boiler/burner systems monitoring (up to 99
burner/burner systems). Each burner control, Fuel/Air
Ratio Control, and Expanded Annunciator present on each
burner system can be viewed individually to determine its
status.

• Local display to a System Monitor
• System Monitor to one or more Local displays
• Gateway for ModBus Master (BAS)
Universal Digital Controllers (UDC 2500/3200/3500 with
modbus) can be used for several burner/boiler applications,
and the S7999D 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
The S7999D is a multiple language OI; English and Spanish
selectable.
The S7999D can be flush mount or behind mounted into a
panel cutout.
Wiring connections to the S7999D are through a removable
8-pin wiring connector.
The S7999D also has a USB port that can be used for:
