SPECIFICATIONS
IMPORTANT
The specifications given in this publication do not

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:
R4140G Flame Safeguard Programming Controls—Flame
Safeguard protection and sequencing controls for use on gas,
oil, coal, or combination burners. See Table 1 for models
available.
Table 1. Models Available.
a
202050C Cover with reset button; heavy duty, metal cover for outside panel mounting.
b
Early spark termination available on terminal 18 (5 second ignition and 5 second pilot only).
c
If used for direct spark ignition (oil or gas), the flame-establishing period is 10 seconds.
Interlock Circuits:
Start Interlocks (R4140G1049, G1056, G1064, G1114,
G1122, G1148 and G1171)—System controls must be
in proper positions or programmer will not start.
Preignition Interlocks (R4140G1007, G1015, and
G1106)—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.
Running Interlocks (all models)—Must be closed (airflow
must be proven, fuel pressure must not be too low or
too high) within 9.5 seconds after startup or ignition
trials cannot be started. Running interlocks must remain
closed through the Run 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 52 seconds
until low fire proving switch closes, indicating damper is
closed prior to ignition.
