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.

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
