APPLICATION

The S7830 Expanded Annunciator is an enhancement module
for use with 7800 SERIES Relay Modules. The S7830 is a
microprocessor-based device designed to monitor the status
of a series string of limit, control, and interlock contacts for a
commercial or industrial burner. The S7830 acts as a system
monitor and enhances fault and status messages of the 7800
SERIES burner control.

FEATURES

• 26 status light emitting diodes (LED).
• Front panel LED array, arranged in a pattern to clearly
indicate the flow of line voltage through the string of
limits, controls and interlocks.
• Selectable current and first-out LED array display
status.
• Power and proper operation indicating LED.
• Common Universal Mounting Subbase (Q7800A or B).
• 21 monitored contact points.
• Access for external electrical voltage checks.
• Communication interface capability.
• Capable of programmable limit or interlock messages
using the S7800A1142 Keyboard Display Module
(KDM).
• Open Lockout interlocks are indicated with a flashing
status LED when used with Relay Module Models with
Lockout Interlock feature.
• Hold messages displayed on the KDM are enhanced
with the Expanded Annuciator terminal description
information that is causing the hold (low water cutoff
for example).
• LED operational test.
• 36 additional 7800 SERIES fault and hold messages.
