ground must be capable of conducting the current to blow a 15A fuse (or breaker) in the event of an internal short circuit. the S7830
needs a low impedance ground connection to the equipment frame that, in turn, needs a low impedance connection to earth ground.
For a ground path to be low impedance at RF frequencies, the connection must be made with minimum length conductors that have
maximum surface areas. Wide straps or brackets, rather than leadwires, are preferred. Be careful to verify that the mechanically
tightened joints along the ground path, such as pipe or conduit threads or surfaces held together with fasteners, are free of
nonconductive coatings and are protected against mating surface corrosion.

7800 SERIES S7830 EXPANDED ANNUNCIATOR
PRINCIPAL TECHNICAL FEATURES
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 for
the 7800 SERIES burner control.
ControlBus Communications
The S7830 provides interfaces with the 7800 SERIES Relay
module through a three-wire RS-485 interface. Using this
communications bus, the S7830 provides additional first-out
annunciation, burner hold, and current status information for
the control, limit and interlock string of the burner equipment.
LED Array
The S7830 provides visual indication of the status of the
burner equipment control, limit and interlock string. The string
of contact and switch points are individually identified with a
colored LED. When power is present at the contact point, the
LED is lighted. When the contact point is de-energized, the
LED is dark. If the contact or switch is identified as the first-out
annunciation point, the LED flashes if the RM78X0L,
RM7838B,C with the Lockout Feature is used or if the feature
is enabled (RM7895, 6, 7, or 8 with JR2 configuration resistor
removed).
Opto-Isolator Coupling
The S7830 uses opto-isolators to monitor the limit string and
couple the line voltage input to the microprocessor. An optoisolator allows a microprocessor to determine the status of
line voltage at control, limit or interlock switch points. Using
this capability, the microprocessor is able to determine the
current as well as first-out status of 23 digital points, each
representing specific burner control, limit or interlock switches.

7800 SERIES S7830 EXPANDED ANNUNCIATOR
IMPORTANT
1. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used
in accordance with these instructions, may cause
interference for radio communications. It has been
tested and found to comply with the limits of a Class
B computing device of part 15 of FCC rules, which
are designed to provide reasonable protection
against such interference when operated in a
commercial environment. Operation of this
equipment in a residential area may cause
interference; in which case, the user, at their own
expense, may be required to take whatever
measures are required to correct this interference.
2. This digital apparatus does not exceed the Class B
limits for radio noise, set out in the Radio Interference Regulations of the Canadian Department of
Communications.
3. If a control, limit or interlock is not used with the
installation, a jumper must be installed in the S7830
wiring subbase. DO NOT PLACE JUMPER WIRES
ACROSS THE INSTALLATION CONTROL, LIMITS
AND INTERLOCKS. For example, if Auxiliary Limit #
1(Aux Limit#1) is not used, place a jumper wire
between terminals 6 and 7 on the S7830 wiring
subbase.
4. For straight gas burner applications, the oil limit and
interlock inputs DO NOT need to be jumpered.
5. For straight oil burner applications, the gas limit and
interlock inputs DO NOT need to be jumpered.
6. For combination gas-oil burner applications, a
double pole, double throw (dpdt) fuel select switch is
required. See Fig. 3.
7. For communications ControlBus connections in
excess of 100 feet (30 meters), a 120 ohm, 1/4 watt
minimum, termination resistor may be required
across terminals 1(a) and 2(b) of the electrical connectors. Cable shield must be terminated to ground
at both ends. If shielded cable is NOT used, use
three-wire twisted cable.
8. The 7800 SERIES Relay Module control point can
be tied into the S7830:
• For dual fuel burners, from terminals 6 to 11,
inclusive.
• For single fuel burners, from terminals 6 to 9,
inclusive.
Humidity
Install the S7830 where the relative humidity never reaches
the saturation point. The S7830 is designed to operate in a
maximum 85% relative humidity, continuous, noncondensing,
moisture environment. Condensing moisture can cause
erratic operation.
Vibration
Do not install the S7830 where it could be subjected to
vibration in excess of 0.5G continuous, maximum.
Weather
The S7830 is not designed to be weather tight. If installed
outdoors, the S7830 must be protected by a weather-tight,
NEMA 4, enclosure.Mounting Wiring Subbase
NOTE: For installation dimensions, see Fig. 1 or 2.
1. Mount the subbase in any position except horizontally
with the bifurcated subbase contacts pointed down (on
the row F). A vertical mounting position is recommended. Any other position decreases the maximum
ambient temperature rating.
2. Select a location on a wall, burner surface, or within an
electrical control panel. Be sure to allow adequate
clearance for electrical voltage probe tests, electrical
field connections, and wiring of the RS-485 ControlBus
to the 7800 SERIES Relay Module. The S7830 must be
within 1000 feet (305 meters) of the 7800 SERIES
Relay Module for proper communication of first-out
annunciation and current burner status information.
3. Use the back of the subbase as a template to mark the
four screw locations and drill pilot holes.
4. Insert four No. 6 screws for mounting, and tighten
securely.
WIRING
WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property
damage.
Disconnect the power supply from the main
disconnect before beginning installation to prevent
electrical shock and equipment damage. More than
one disconnect can be required.
1. Refer to Fig. 3 for proper subbase wiring. The system
wiring must follow the order shown in Fig. 3.
NOTE: With the S7800A1142 Keyboard Display Module, you
can name the limits and interlocks to match your
system.
2. All wiring must comply with all appropriate electrical
codes, ordinances and regulations. Wiring, where
required, must comply with NEC Class 1 (Line Voltage).
3. Recommended wire size and type:
a. Line Voltage:
(1) Use No. 14, 16 or 18 gauge (TTW60C or
THW75C or THHN90C), 600 volt insulation for
all line voltage terminals.
b. RS-485 ControlBus:
(1) Use three-wire twisted cable. Some installations
may require shielded cable; use Belden 8771 or
equivalent. For connections in excess of 100
feet (30 meters), a 120 ohm, 1/4 watt minimum,
termination resistor may be placed across
terminals 1(a) and 2(b) of the electrical
connectors.
4. Recommended grounding practices:
a. The earth ground provides for a connection between
the wiring subbase and the control panel or the
equipment. The earth ground wire must be capable
of conducting the current to blow the 15A type SC
fast blow fuse (or breaker) in the event of an internal
short circuit.
b. The S7830 needs a low impedance ground
connection to the equipment frame which, in turn,
needs a low impedance ground connection to earth
ground. For a ground path to be low impedance at
RF frequencies, the connection must be made with
minimum length conductors that have a maximum
5 65-0101—03

surface area. Wide straps or brackets are preferred
rather than leadwires. Be careful to ensure that
mechanically tightened joints along the ground path,
such as pipe or conduit threads, or surfaces held
together with fasteners, are free of nonconductive
coatings and are protected against corrosion on
mating surfaces.
c. The ControlBus shielded cable, if used, should be
connected to the signal ground terminal 3(c)
provided as a part of the S7830 ControlBus
connector. The shield should be connected at both
ends to earth ground.

The S7830 is designed to operate in conjunction with 7800
SERIES Relay Modules to enhance information for causes of
burner lockouts and sequence status by monitoring up to 21
digital contact points. Current burner status and lockout
information is displayed at the S7830 through an array of 26
LED and also on the face of the S7800 Keyboard Display
Module. The information from the S7830 is communicated
through a three-wire twisted ControlBus communications link
to the S7800.

Page 10
7800 SERIES S7830 EXPANDED ANNUNCIATOR
NOTE: Not all 7800 SERIES devices lock out for an open
interlock. Annunciation is available as hold
messages but an alarm will not be generated.
First-Out Annunciation
The S7830 does not cause burner lockouts. Only the 7800
SERIES Relay Modules with the lockout feature (RM78X0L,
RM7838B, C or RM7895, 6, 7, 8 with configuration resistor
feature, JR2 clipped) can cause a burner lockout (safety
shutdown) for abnormal interlock conditions. From the time a
lockout occurs, the expanded first-out annunciation is
communicated as follows:
1. The 7800 SERIES Relay Module causes a lockout due
to, for example, the opening of the Lockout Interlock
circuit.
2. The 7800 SERIES Relay Module communicates the
lockout status, including the time when the fault
occurred, to any modules connected to the RS-485
ControlBus communication network.
3. The S7830 recognizes the lockout status of the 7800
SERIES Relay Module and the time when the fault
occurred.
4. The S7830 begins to review the status of all switched
inputs on a grouping of several line cycles time duration.
When identifying a normal status of all switched inputs,
the S7830 will advance one line cycle grouping to
identify the first switched input that opened after the
normal status. This switch point, for example, air flow
switch, is identified as the first-out annunciation point.
5. This first-out information is communicated by the S7830
to:
a. The 7800 SERIES Relay Module to enhance the
lockout display message, for example from Lockout
Interlock fault to Airflow Switch fault.
b. The array of 26 status LED on the face of the S7830
that are latched to the lockout mode to visually
indicate which switch is the first-out point. For the
example being used:
(1) All LED electrically upstream from the airflow
switch will be illuminated constantly.
(2) The airflow switch LED will flash on and off to
indicate that this switch was the first-out cause of
the lockout condition.
(3) Any LED electrically downstream from the
first-out point will remain dark because the circuit
upstream of that point has been broken.
(4) The first-out LED will be latched to indicate the
mode of the 26-led array.
6. When the lockout is cleared by resetting the 7800
SERIES Relay Module, the S7830 is automatically
changed from first-out to current.
Current Status
The S7830 provides current status information, through the
RS-485 ControlBus, defining which switch point is causing a
hold condition. The 7800 SERIES Relay Module places the
burner in Standby when the control input, terminal 6, opens
(terminal 17 on VP devices: RM7898, RM7840G/L and
RM7800L). The exact switch causing the burner to enter
Standby may be one of several controls, limits or interlocks.
The S7830, through the RS-485 ControlBus, communicates
the current status of the 21 monitored digital contacts points
twice each second. For example, if the Standby hold is being
caused by the Burner Switch being open, the Standby hold
message will be enhanced to identify the Burner Switch,
providing information that identifies the reason for the hold.
S7830 User Interface

2. Power LED
a. The Power LED can have one of three states:
(1) LED ON indicates an abnormal condition that
shows power is present at the S7830, but the
device is inoperative (reset the S7830).
(2) LED OFF indicates:
(a)Power is absent at the S7830.
(b)Power is present at the S7830, but the Power
LED is defective.
(c)Power is present at the S7830, the Power
LED is not burned out, but the device is
inoperative. (Reset the S7830.)
(3) LED FLASHING (OFF briefly every four
seconds) indicates power is present at the
S7830 and the device is operating properly.
3. System Lockout LED
a. The System Lockout LED can have one of two
states:
(1) LED ON indicates the 7800 SERIES Relay Mod-
ule is in a lockout state.
(2) LED OFF indicates the 7800 SERIES Relay
Module is in a normal operating status, power is
off, or the LED is defective.

7800 SERIES S7830 EXPANDED ANNUNCIATOR
4. First-out LED
a. The First-out LED can have one of three states:
(1) LED ON indicates the LED array is latched in a
mode showing the status at the time of the
lockout.
(2) LED OFF indicates the LED array is in a Current
Status mode, power is off, or the LED is
defective.
(3) LED FLASHING indicates the Select keypad is
being depressed constantly (four seconds or
longer) and a lockout is not present.
5. Current LED
a. The Current LED can have one of two states:
(1) LED ON indicates the LED array is in a Current
status.
(2) LED OFF indicates the LED array is latched in a
first-out mode, power is off or the LED is
defective.
Select Keypad Functions
The Select Keypad provides two functions:
1. When depressed momentarily, the S7830 mode will
toggle between lockout (first-out) and Current status.
Therefore, the operator can actively switch back and
forth between these two modes to define the status of
the 21 digital switched inputs.
2. When depressed constantly (four seconds), all 25 LED
(exclusive of the POWER LED) in the array will be
forced on. This is a means to check to make certain that
an LED can illuminate or is operating properly.
Reset Keypad Function
The Reset Keypad is used to cause an electrical reset of the
S7830. If the operation of the S7830 is in question, an attempt
can be made to reset the internal microprocessor. It is not
necessary to depress the Reset Keypad after a system
lockout. Once the 7800 SERIES Relay Module is reset, the
S7830 LED array automatically will be reset to the Current
status mode.

CHECKOUT
Several basic steps can be take to check proper operation of
the S7830.
1. Depress and hold the Select keypad for five seconds.
All 25 LED (Exclusive of the Power LED) should light.
2. Through the S7800 Keyboard Display Module, access
the S7830 Expanded Annunciator Informational Index. If
the S7830 is operating properly, it should be possible to
access the status of all switched points.
3. Open equipment control, limits, and interlock inputs.
The S7830 LED array and S7800 Keyboard Display
Module should indicate the cause of the burner lockout
and switch point status.
IMPORTANT
Restore ALL controls, limits and interlock inputs,
altered in step 3, to proper operation. DO NOT
PLACE JUMPER WIRES ACROSS THE
INSTALLATION CONTROLS, LIMITS AND
INTERLOCKS.
4. If improper operation is identified, check all S7830
wiring against Fig. 3 and correct any errors. If problems
persist, reset the S7830. If problems continue to persist,
replace the S7830 Expanded Annunciator.
NOTE: The S7830 is a monitoring device. If wired correctly,
the S7830 will not shut the system down.
The S7830 can be removed from the wiring subbase
and the equipment should operate in a normal manner and shutdown if limit or interlock were to open.
