1 0G Flame Safeguard Programming Controls PODUCT DATA APPLICATION The 0G Flame Safeguard Programmers provide flameout protection plus automatic sequencing of the burner motor (blower), firing rate motor, ignition, pilot valve, and main fuel valve(s) for commercial and industrial burners using gas, oil, coal, or a combination of fuels. FEATUES Approvals: Underwriters Laboratories Inc. listed or component recognized, Canadian Standards Association certified, and Factory Mutual approved for automatic fired burners. The 0 directly replaces the 0 for most applications and mounts on the same Q0A iring Subbase. Low-high-low purge programmers. Field selectable main burner flame-establishing period. Early spark termination (five-second ignition and fivesecond pilot only) available on some models. Plug-in, solid state, flame signal amplifiers are colorcoded and interchangeable to allow the use of any type of flame detector-flame rod, photocell, infrared detector, or ultraviolet detector. Amplifier capability includes three standard models, three Dynamic Self-Check models, and one Dynamic Ampli-Check model. C or A Dynamic Self-Check Amplifier, when used with an ultraviolet flame detector with a self-checking shutter (C with a C0E or F; A with a C0), tests all electronic components in the flame detection system (amplifier and detector) 0 to 0 times a minute during burner operation and shuts down the burner if the detection system fails. Dynamic Self-Check Amplifier, when used with a rectifying flame rod (which is considered fail-safe), or Dynamic Ampli-Check Amplifier, when used with a C0A Infrared (lead sulfide) Flame Detector, tests the flame signal amplifier at least 0 times a minute during burner operation and shuts down the burner if the amplifier fails. All models feature capability of proving low fire position of the firing rate motor before starting ignition trials. Provisions for connecting preignition or start interlocks (depending on model) to prove the proper conditions for startup, and for a combustion airflow switch to prove airflow throughout the operating cycle. All models have -wire firing rate switching circuitry firing rate can be modulated while the burner is firing, and the firing rate motor can be driven to both low and high fire positions during prepurge. Safe start check at startup and during prepurge. If flame relay K is holding in at startup, the programmer cannot be started. If a flame (or a condition simulating a flame) is detected during prepurge, ignition trials cannot be started and the programmer recycles. Safety shutdown occurs on failure to ignite the pilot or main burner, on loss of flame during the un period, or if the flame detection system fails (if a self-checking system is used). All relays are visible, labeled, and easily accessible. Alarm terminal is available to operate an external, line voltage alarm on safety shutdown. Contents Application... Features...

2 0G FLAME SAFEGUAD POGAMMING CONTOLS SPECIFICATIONS IMPOTANT The specifications given in this publication do not include normal manufacturing tolerances. Therefore, this unit may not match the listed specifications exactly. Also, this product is tested and calibrated under closely controlled conditions, and some minor differences in performance can be expected if those conditions are changed. MODELS: 0G Flame Safeguard Programming Controls Flame Safeguard protection and sequencing controls for use on gas, oil, coal, or combination burners. See Table for models available. a b c Model ith Covera Timer Cycle (sec) Prepurge (sec) ODEING INFOMATION Table. Models Available. Early Spark Terminationb 000C Cover with reset button; heavy duty, metal cover for outside panel mounting. Early spark termination available on terminal ( second ignition and second pilot only). If used for direct spark ignition (oil or gas), the flame-establishing period is 0 seconds. Interlock Circuits: Start Interlocks (0G0, G0, G0, G, G, G and G) System controls must be in proper positions or programmer will not start. Preignition Interlocks (0G00, G0, and G0) Must be closed to start programmer. Prevent ignition trials if interlocks open during prepurge; timer recycles the programmer and system restarts if condition is self-correcting. unning Interlocks (all models) Must be closed (airflow must be proven, fuel pressure must not be too low or too high) within. seconds after startup or ignition trials cannot be started. unning interlocks must remain closed through the un period or the automatic fuel valves de-energize, the burner flame(s) goes out, and the timer recycles the programmer. Low Fire Interlock (all models) Timer stops at seconds until low fire proving switch closes, indicating damper is closed prior to ignition.

3 0G FLAME SAFEGUAD POGAMMING CONTOLS Safety Features: Safe Start Check For the presence of a flame (or a condition simulating a flame) provided at startup and during prepurge. If the flame relay K is pulled in at startup, K is open and the programmer cannot be started. If the flame relay K pulls in during prepurge (before. seconds), K opens, relay K drops out, and ignition trials cannot be started. Instead, the timer completes its revolution and stops at the standby position (zero seconds). If the flame relay K drops out by the end of the cycle, the programmer restarts the system. Safety Shutdown Ignition transformer and all automatic fuel valves de-energize. The lockout switch trips and locks out the programmer. If used, the external alarm is energized. The timer completes its revolution and locks up at the stand-by position (zero seconds). The lockout switch must be manually reset to restart the system. Safety Shutdown occurs on: Failure to ignite the pilot (or first stage burner if using direct spark ignition). Failure to light the main burner (unless monitoring an intermittent pilot). Loss of flame during the un period. Failure in the flame detection system (if a selfchecking system is used, see Table ). Flame Failure esponse Time to seconds.
