Introduction 1 PRODUCT The Eclipse Combustion Bi-Flame Burner Monitoring System controls the start-up sequence and monitors the flame of two DESCRIPTION individual gas, oil, or combination gas/oil burners connected to a common valve train. Its dynamic on-board testing checks for faulty relays, proof of valve closure, high and low fire switch interlocks, and shorted air switch. The microcomputer based system features a plug-in modular design so any of the circuit board modules attached to the mot

Modules Description 3 INTRODUCTION In this section, you will find descriptions of the various modules which comprise the Bi-Flame dual burner flame monitoring system, whether standard or optional items. MODULE DESCRIPTION Relay Module AND IDENTIFICATION The relay module contains the output relays which provide power for operating the ignition coil, pilot valve, main valve, combustion fan and alarm. This module is mounted in the first position on the left of the motherboard closest to the output

Sensor Module The sensor module is the flame sensing module of the Bi-Flame. It is mounted in the furthest right position of the mother board. On the front of the sensor module are two “Flame On” LED’s, which illuminate when a flame is detected at the corresponding burner. Directly below the “Flame ON” LED are “Flame Fail” LED’s, which energize to show the first burner to lose its signal. The sensor module incorporates test point connection jacks in the front of the unit. Using these, the flame

DIP Switch Selection 4 INTRODUCTION This section details the location, selection and description of the Bi-Flame DIP switches, which allow for sequence and timing func- tions as well as system configuration. Caution: To avoid electric shock, shut off the power supply when installing any control device. Flame monitoring systems must be installed by a qualified, licensed technician. DIP SWITCH LOCATION All of the DIP switches are located in the logic module, which is mounted in the second position

Function Summary 5 INTRODUCTION This section describes the function features of the Bi-Flame that can be found on the various terminal strips and the modules of the Bi- Flame. Combustion Air Flow Check Terminal The Bi-Flame checks that the combustion air flow switch is open be- fore start-up, closed during operation and open again at burner shut- down, thus preventing operation with an air switch that is defective, maladjusted or jumpered. Main Fuel Valve Proof-of-Closure Terminal The Bi-Flame c

Recycle Mode When selected, the Bi-Flame will restart the sequence after flame or air failure. The recycle mode allows the system to re-initiate the start-up sequence automatically, once the main burners have been operating for at least 20 seconds. If the pilot flame fails to light dur- ing recycling, the system will lock out and annunciate a pilot flame fail. If the recycle is successful and the main burners are operational for at least 20 seconds, the system is ready for another recycle. At n

Auxiliary Inputs This feature provides four auxiliary inputs which are monitored by the Bi-Flame as alarm interlocks. This means that when the input voltage is interrupted, the system locks out and will annunciate on the optional remote display unit. A voltage of 120 VAC must be present at the input for the Bi-Flame system to operate. If an auxiliary input loses its voltage for more than one second while the interlocks and limits input is powered, a lockout condition will occur. If the Bi-Flame

History Log (continued) 4) Release the ENTER key and the most recent lockout message will display for seven seconds. 5) If you wish to see the next lockout message, press and release the ENTER key before the seven second time duration ends of the most recent lockout message display. This will prompt the next lockout message. If desired, continue this procedure until the maximum of ten lockout messages has been displayed (re- member that the highest record number is the most recent lockout messag

Valve Leak Sensing Device (VLSD) Interface The Bi-Flame Valve Leak Sensing Device (VLSD or VDK) interface provides a 120 VAC output which triggers the start of the test pe- riod. An input is also provided which receives a 120 VAC signal from the VLSD. If the signal is received within the selected test pe- riod (40 or 110 seconds, see page 13), then the test has been suc- cessfully completed. This option includes the required sequential software to initiate the valve leak test on start-up and sh

Remote Display Unit The remote display with keypad allows remote reset and activation of the history log option. It is panel mountable and features a back- lit liquid crystal display in a 1/4 DIN housing. It connects to the Bi- Flame by a six or ten foot cable. The display incorporates the fol- lowing features: 1) Provides status messages for the Bi-Flame sequence. (See Sec- tion 10) 2) Indicates lockout conditions when they occur, as well as the amount of time into the sequence when the lockou

Air This LED illuminates when the air switch is closed and power is thereby applied to the air switch input. The Bi-Flame also checks this input for an air switch short (see “Combustion Air Flow Check Ter- minal” on page 14). Purge This LED illuminates whenever the combustion blower is energized, including the purge period and the main burner period of the se- quence. It blinks on and off while the purge is in process and remains constant when the purge process is complete. Burner On This LED i
