PRODUCT GUIDE SPECIFICATION

FIREYE M-SERIES II

FLAME SAFEGUARD CONTROL

1. GENERAL

1.1 OVERVIEW

Each burner shall be equipped with a Burner Management Flame Safeguard Control System. The control shall provide automatic sequencing and continuous flame monitoring of the burner through prepurge (Series 200 and Series 500 programmer modules only), pilot trial for ignition (PTFI), and run.

2. SYSTEM HARDWARE

2.1

2.1.1 The programmer module shall determine timing

2.1.2 The programmer module shall incorporate five LED

FLAME SAFEGUARD CONTROL

The Burner Management Fla me Safeguard Control shall be of a modular design, with the programmer and amplifier modules plugging into the chassis.

functions for prepurge (Series 200 and Series 500 models only), PTFI, and intermittent or interrupted operation.

indicator lights to indicate the operating status of the control. The LED's shall annunciate operating control closed, air flow switch closed, pilot trial for ignition, flame signal present, and alarm.

1.1.1 The control system shall be provided by Fireye or written

approved equal.

1.2

2.1.4 The programmer module shall incorporate a "run-check"

2.1.5 The amplifier module shall determine the type of flame

CODES AND STANDARDS

The control shall be listed by Under writers Labora tories, Factory Mutual, and Canadian Standards Associates for its intended purposes.

switch (Series 500 programmer models only) to assist in testing the size, position, and stabilization of the pilot.

scanner (ultra-violet or flame rod/photocell) and flame failure response time (FFRT). Test jacks shall be provided on the amplifier module to measure flame signal strength during operation.

2.1.3 The programmer module shall incorporate dip-switches

(Series 200 and Series 500 programmer models only) to select purge timing, pilot trial for ignition timing, and recycle/non-recycle operation.

2.3

WIRING BASE

A wiring base shall be provided which will allow for all system terminations to be completely wired prior to the installation of the control. The control shall be removable or replaceable without remov ing any wiri ng terminations. The user shall have acc ess to the wiring terminals to test for voltage while the control is installed on the wiring base.

3. SEQUENCE OF OPERATION

CONTROL ALGORTIHM

2.3.1 The wiring base shall provide line voltage terminal inputs from direct connection of limit and operating controls, air flow switch, burner motor, ignition, pilot valves, main fuel valves, and alarm.

The control shall accomplish a safe start check during each start. If flame (real or simulated) is detected prior to a start or during purge, the fuel valves shall not be energized, and the control shall initiate a safety lockout.

3.1.1 Once the operating control circuit is closed, the control

shall energize the blower motor and check to prove the air flow switch is clo s ed.

3.1.2 After the air flow switch is proven closed, the control

shall initiate a prepurge (Series 200 and Series 500 programmer modules only).

3.1.3 Upon completion of prepurge, the control shall initiate

pilot trial for ignition (PTFI).

3.1.4 When flame signal is proven during PTFI, the control

shall de-energize the ignition transformer and energize the main fuel valve.

4. PRODUCT INFORMATION

4.1 - The control chassis sh all b e th e Fireye M C120.

- The Programmer Module shall be the MP230 (or appropriate model).

- The Amplifier Module shall be the MAUV1 ultra-violet type (or appropriate model).

- The ultra-violet scanner sh al l b e th e Fi reye UV1A 6 ( or ap p ro p riat e mo del) .

3.1.5 Safety shutdown shall occur following (1) failure to prove the pilot flame during PTFI, or (2) loss of flame signal after main fuel valve is energized for the selected Flame Failure Response Time and the programmer is set for non-recycle operation (Series 200 and Series 500 programmer modules only).

3.1.5 The system shall recycle automatically under control of the operating control and when power is restored following a power failure. Manual reset shall be required following any safety lockout, even after a power failure. When in a lockout condition, power interruptions will not recycle the cont ro l.
