Fireye Flame-Monitor: New and Improved Technology

Burner programmers have entered the computer age with microprocessor technology.  The technology is enhancing their capabilities at an accelerated rate.  Competition breeds improvements; one company’s latest product line is soon surpassed by another company’s “new and improved” product line.

Fireye’s E100 series Flame-Monitors came to the marketplace well before the 7800 series from Honeywell.  When the 7800 series became available, its features eclipsed the E100’s, especially the capabilities of the S7800 display module.  The 7800 Series was a completely new line, from the wiring base up.  Nothing in the 7800 Series was compatible with previous Honeywell programmers, as far as wiring was concerned.  Even terminal designations were changed.  The E110 Series from Fireye, with ED510 display module, catches up to the concept of the 7800 Series, with no wiring changes from the E100.

The E100 consisted of an EB700 chassis, EC600 dust cover, ED500 display, and a mounting screw.  In order to complete the entire programmer, a wiring base, (60-1386-2) for surface mounting, or a (60-1466-2) for panel mounting, an EP programmer module, and a flame amplifier module was needed.

The E110 consisted of the same EB700 chassis, EC600 dust cover, and a mounting screw.  No display module was included!  A display module must be added to the E110!  The major difference between the E100 and the E110 was that the E100 came with a display module (ED500) and the E110 did not.  The E110 mounting screw was shorter than the mounting screw with the E100.  The E110 plus a display module was priced exactly the same as the old E100; therefore, Climatic Control Company will stock only the E110 from now on.

What really differentiated the latest version of the Flame-Monitor from its predecessor are the enhanced EP programmer and the ED510 display.  The improved EP programmers did not have new numbers to differentiate them from the old style EP programmers, since they were totally compatible with any Flame-Monitor.  Any old E100 that requires an EP replacement can use the improved programmer.  Fireye deliberately did not change the numbers of the EP programmers to emphasize this compatibility feature.  The new EP programmers come with six dipswitches to give the user various selectable functions, and the ability to use the new ED510 display.  The user has the ability to use an ED510 display in place of an ED500, but they do not have to replace an existing ED500 when replacing an EP programmer.  Using the new EP programmer, just as it comes out of the box, duplicates the function of the old EP being replaced. 

Once the new-style programmer is in a Flame-Monitor, the ED510 display can be used.  The ED510 display is priced exactly the same as an ED500. 

Once the new-style EP programmer is in the E100 or E110, the ED510 display can be used.  The ED510 is now an excellent service tool, similar to the Honeywell S7800.  The ED510 can access historical information and identify the components of the Flame-Monitor being used through use of a tactile three-key keypad.  The ED510 can be used, even if an ED500 is in the Flame-Monitor. 

Note:   When plugging in the ED510 display, be sure it is powered down to prevent arcing of the cable pins that could damage the ED510 or programmer. 

The ED510 could eliminate the need for an E900 service tool.  The E900 service tool has much more capability than an ED510, but the E900 is expensive.  In most cases, the diagnostic information available through the ED510 is all a service technician needs to diagnose burner problems.

E900’s do not work with EP programmers that have engineering codes of 26 or later.  The programmers can overwhelm the E900 with a burst of information that the E900 cannot handle.  Fireye is working with the manufacturer of the E900 to solve this problem, but as of this writing, has no solution. 

Let’s review a bit and look at each component of the new E110 Series in detail.

First, there are no changes in the wiring bases or amplifiers.

Second, remember the E110 is an E100 without a display.

Third, the EP programmers have been enhanced, but their number designation remains the same to emphasize their backwards compatibility.  The features added to the EP programmers are a set of six dipswitches. 

On the EP160, 161, 165, 170, 260, 261, 265, and 270:

Dipswitch Designations:

1 and 2                Inactive.  

3, 4, and 5          Can be configured to select high fire purge timings from 30 seconds to 30 minutes. 

6                          Allows the option of proving the 3 to P interlock circuit (usually an airflow switch) is open at the start of the operating cycle. 

For instance, if the A.F.S. contact is welded closed, and dipswitch 6 is “up”, on a call for heat, the control will recognize this condition, hold for one minute waiting for the circuit 3 to P to open.  After one minute, if 3 to P remains a closed circuit, the control will lock out.

On the EP380, 381, 382, and 390, all 6 dipswitches are active: 

Dipswitch Designations

1.                         Determines if the control will recycle or not recycle on detecting an open circuit between 3 and P.

2.                        Configures terminal 6 to be either intermittent or interrupted ignition.

3, 4, and 5          Selects purge time as on the EP160’s, 260’s.

6                         Allows the option of monitoring the 3 to P interlock circuit on startup.

The “star” of the E110 series is the ED510.  It is a complete redesign of the ED500.  It mounts directly to the front of the new style EP programmers and accesses the programmers with a short plug-in cable included with every ED510.  The ED510 can be remotely mounted by using (129-145-1) or (129-145-2) mounting kit.  These kits consist of a mounting plate, gasket, two mounting screws, and a connecting plug-in cable, 4' long in the (129-145-1), 8' long in the (129-145-2) kit.  ED610’s are used for remote operation as far as 700'.  An ED610 is similar to the ED600, but uses telephone jack connections instead of cables. 

Remote reset only, still uses the ED150 cables.  Remember, remote operation of the ED510 is also requiring the reset to be remote too, since reset is built into the ED510.  The ED510 is an LCD display.  Because of the LCD’s, Fireye describes the temperature rating of the ED510 as “+32°F to +140°F”.  The low limit of +32°F is common with LCD’s since LCD’s will freeze and become inoperative.  Fireye is very aware of this problem.  The LCD’s freezing should not destroy the ED510.  Once thawed out, it is supposed to function again.  A Flame-Monitor with an ED510 installed in an ambient below +32°F will function down to -40°F, since the display has nothing to do with running the control.  Fireye chose the LCD’s because they use much less power than LED displays, such as in the ED500.  With the new EP programmer, power supply at reasonable cost was at a premium.

A change may be made.  Fireye has stated they have gotten calls on the LCD display low temperature limit, and to satisfy distributor’s concerns, they are still studying the problem of LCD’s.

Note: Be sure to refer to the latest bulletins for up-to-date information, as these bulletins are no longer current. 

Bulletin ED5101, page 2, contrast control.  The contrast control is not designated in any way.  It is the recessed allen-head screw in the back of the ED510.  If the ED510 is used as a service tool or in a remote area, it needs a back to cover the printed circuitry.  For now, a homemade back can be made of any non-conducting material.  Fireye will soon have a thin piece of plastic for this.

Bulletin E1101 shows no ambient limits for the E110.  To us, it’s obviously the same as the E100, -40°F to +125°F.  Bulletin E1101, page 4 under “communications”, an E300-3 is shown.  This is actually an E500-3.  Under “remote reset”, all the ED150’s are shown as 3' long.  They actually are available in 6, 15, and 25 feet lengths, as their number indicates after the dash.

Bulletin E-5001 will be reprinted to show how six E110’s and six E340’s can be interfaced with the E500.  Also, “Publication E-500-DATA April 1994says that the E500 works only with EP programmers with engineering code 26 or lower!  This is true only if using the ED550 cables.  The E500 will work with the new EP programmers engineering code 28 when using the telephone jack system.  Instructions are supposed to be coming in the reprint of E-5001 and ED8101.

Bulletin EP2601 April 1994, page 10 shows “Purge Int*”.  This should not be there.  There is no H.F.P.S. used on an EP260.

Bulletin EP1601, April 1994, page 11.  The “Purge Int*” shows up again, but no reference is made for the *.  The H.F.P.S. is used with an EP160, and the star (*) need not be there.

Bulletin ED5101 page 7, about a third of the way down the page, the bulletin mentions “last 15 lockouts”.  This should be “last 6 lockouts”.  On page 9, “user programmed E300 messages”, refers to “Bulletin E-300l for complete details”.  There is nothing in Bulletin E-3001 about this.  You need a disc, E700 or E720 software, and an instruction sheet.
