Use only Eclipse model 5600-90A, 5600-91, 5602-91or 5600-91N4 scanners. Consult the burner manufacturer’s instructions for mounting location.When installing scanners, please consider the following: 1) Position the scanner within 457 mm (18") of the flame. 2) Bushing threads are 1/2 inch F.N.P.T. for scanner models 5600-90A, 5600-91 and 5600-91N4; model 5602-91 has 1 inch F.N.P.T. bushing threads. 3) The ambient temperature limits of each scanner varies, (see specifications). For higher temperatures, use Eclipse heat insulator 49099 or the Heat Block Seal, Model 23HBS, that has a purge fitting. 4) An optional magnifying lens (Eclipse #49600-98) may also be used to increase the flame signal strength in difficult sighting situations. Eclipse Bi-Flame v1.8, Instruction Manual 826, 05/03 SCANNER SIGHTING CONDITIONS 1/3 of Flame LengthMAIN BURNER SCANNERScanner Sight Line U.V. Scanner Sighting Aim scanners at the third of the flame closest to the burner nozzle, as shown at left.This is especially true for oil flames which typically have less UV radiation in the outer flame.The scanner should view the intersection of the pilot and main flames.When sighting scanners, please consider the following: 1) Sight the scanner away from the ignition spark. Sighting the spark or its reflections from burner internals can be misinterpreted as a flame signal. 2) Do not allow the scanner to detect a pilot flame that is too small to ignite the main burner. 3) Perform a minimum pilot test when installing or adjusting any pilot or main burner system; see “Minimum Pilot Test” on page 30. Eclipse Bi-Flame v1.8, Instruction Manual 826, 05/03 Test Procedures INTRODUCTION FLAME SIGNAL STRENGTH MINIMUM PILOT TEST Voltmeter hook-up to the Bi-Flame 8 This section describes the test procedures that must be performed after installation to insure that the Bi-Flame is operating properly; these procedures are mandatory. Insert the positive probe of a 0-15 VDC, one megohm/volt meter into the test point on the front cover, as shown in the photo at left. Connect the negative probe to ground. A good flame signal strength will read between 6 and 11 VDC; anything below 4 VDC is inadequate. Run the following test procedures to ensure that the sensor will not detect a pilot flame too small to reliably light the main flame: 1) Manually shut off the fuel supply to the burner, but not to the pilot. 2) Start the system normally. 3) To enter the pilot test mode, press the RESET and ENTER buttons simultaneously.Then release the RESET button but keep the ENTER button depressed for another 10 seconds.The Limits LED will blink, signalling that the system is in the pilot test mode. 4) The control will hold the operating sequence at the pilot flame step. Measure signal strength as described above. 5) Reduce pilot fuel until the flame relay drops out. Increase pilot fuel until the flame signal is greater than 4 VDC, and flame relay just manages to pull in.This is the minimum pilot. If you don’t think this flame will be able to safely light the main burner, realign the sensor so that it requires a larger pilot flame and repeat steps 2 through 5. 6) Push the RESET button to exit the test mode and begin the normal start-up sequence again. 7) When the sequence reaches the main flame trial for ignition, smoothly restore the fuel supply to the burner. If the main burner does not light within five seconds, immediately shut off the burner supply to shut down the system. Realign the sensor so that it requires a larger pilot flame. Repeat steps 1 through 6 until the main burner lights off smoothly and reliably. Eclipse Bi-Flame v1.8, Instruction Manual 826, 05/03 PILOT FLAME FAILURE TEST MAIN FLAME FAIULRE TEST (For Interrupted Pilot Systems) SPARK SIGHTING TEST LIMITS AND INTERLOCK TESTS 1) Manually shut off the fuel supply to one individual pilot and main burner, or all burners if the system has a single fuel supply. 2) Place system in pilot test mode (please refer to page 15). 3) Start the system normally.The controller should lock out*; if it doesn’t, then the controller is detecting a false flame signal (see Section 7). Find the problem and correct it before resuming normal operation. 4) Repeat steps 1 through 4 until all burners have been tested. 1) Manually shut off the fuel supply to the main burner, or all burners if the system has a single fuel supply, but not to the pilot. 2) Start the system normally.This should ignite the pilot and lock out* after pilot interruption. If the system does not lock out, the controller is detecting a false flame signal (see Section 7). Find the problem and correct it before resuming normal operation. 3) Repeat steps 1 through 3 until all burners have been tested. 1) Manually shut off the fuel supply to the pilot and main burner. 2) Start the system normally. 3) Measure the flame signal as described in “Flame Signal Strength” in this section. 4) If a flame signal greater than 4 VDC is measured for more than three seconds during the t...
