FLAME SCANNERS
CAUTION: The UV1, UV2, UV8A, UV90 and 45UV3 ultra-violet flame scanners and associ-
ated amplifier modules are non-self checking UV systems and should be applied only to burn-
ers that cycle often (e.g.: a minimum of once per 12 hours) in order for the safety checking
circuit to be exercised. If component checking is required during burner operation for con-
stantly fired burners, utilize the self-checking ultra-violet flame scanners (45UV5) with asso-
ciated amplifier module (EUVS4), or the infrared flame scanner (48PT2) with associated
Auto Check amplifier (E1R1, E1R2, E1R3).
FLAME-MONITOR PROGRAMMER SELECTION
All programmers for the Flame-Monitor Series are designated with the prefix "EP" or “EPD.” The
functional operation, flame failure response time, purge timings, firing rate motor circuit, trial for
ignition timings, recycling function and display messages are determined by the programmer.
Following is a chart of the most common programmers. Refer to the appropriate product bulletin for
a detailed description of the operation of each programmer.
Take note of the programming sequence chart for each programming module for the proper explana-
tion of pre-purge timings.
WARNING: THE INAPPROPRIATE SELECTION OR APPLICATION OF A PROGRAM-
MER MODULE COULD RESULT IN AN UNSAFE CONDITION HAZARDOUS TO LIFE
AND PROPERTY. The various programmer modules (EP(D)160, EP(D)260 and EP(D)380)
are interchangeable because they plug into a common chassis. Changing the dipswitches
modifies the operation of each programmer module. Care should be taken to insure the
proper dipswitch settings. Refer to the appropriate programmer bulletin for dipswitch set-
tings. Selection of the programmer module and setting the dipswitches for a particular appli-
cation should be made by a competent professional, such as a Boiler/Burner technician
licensed by a state or government agency, engineering personnel of the burner, boiler or fur-
nace manufacturer (OEM) or in the performance of duties based on the information from the
OEM.
