R4140G
Flame Safeguard Programming Controls
PRODUCT DATA
•
R7247C or R7476A Dynamic Self-Check Amplifier,
when used with an ultraviolet flame detector with a
self-checking shutter (R7247C with a C7012E or F;
R7476A with a C7076), tests all electronic components
in the flame detection system (amplifier and detector)
60 to 240 times a minute during burner operation and
shuts down the burner if the detection system fails.
R7247B Dynamic Self-Check Amplifier, when used with
a rectifying flame rod (which is considered fail-safe),
or R7248B Dynamic Ampli-Check Amplifier, when used
with a C7015A Infrared (lead sulfide) Flame Detector,
tests the flame signal amplifier at least 150 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 4-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 2K 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 Run period,
or if the flame detection system fails (if a self-checking
system is used).
•
•
APPLICATION
The R4140G 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.
•
•
•
All relays are visible, labeled, and easily accessible.
Alarm terminal is available to operate an external, line
voltage alarm on safety shutdown.

R4140G FLAME SAFEGUARD PROGRAMMING CONTROLS
Safety Features:
NOTE: Allowable inrush can be up to ten times the pilot duty
rating.
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 2K is pulled in at
startup, 2K2 is open and the programmer cannot be
started. If the flame relay 2K pulls in during prepurge
(before 57.5 seconds), 2K2 opens, relay 1K 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 2K 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:
EXAMPLE: Pilot duty rating = 50 VA.
At 120V, running current is:
50
120
= 0.42A
.
Maximum allowable inrush is ten times
0.42A = 4.2A.

Step-By-Step Operation (R4140G1015)
Start And Prepurge
0 seconds—On a call for heat, the burner controller
contacts close. If the limits and preignition interlocks
are closed and flame relay 2K is not holding in, relay 1K
pulls in through M7B, LS2, 2K2, and the LS HTR
(lockout switch heater—thus proving its continuity).
15 seconds—M11B closes; flame relay 2K can pull in if a
flame (or a condition simulating a flame) is detected. If
detected during prepurge (until 57.5 seconds), 2K pulls
in, 2K2 opens, 1K drops out, and the system shuts
down; the timer completes its revolution and recycles
the programmer (if 2K dropped out).
45 seconds—M10B closes; firing rate motor drives toward
low fire position (closed).
52 seconds—M3A opens; timer stops until the low fire
proving switch closes; timer can be stopped by opening
the timer switch (until 66 seconds when M3A closes
again).

Start and Prepurge
0 seconds—On a call for heat, the burner controller
contacts close. If the limits and preignition interlocks
are closed and flame relay 2K is not holding in, relay 1K
pulls in through M7B, LS2, 2K2, and the LS HTR
(lockout switch heater—thus proving its continuity).
or the system shuts down; the timer completes its
revolution and recycles the programmer.
15 seconds—M11B closes; flame relay 2K can pull in if a
flame (or a condition simulating a flame) is detected. If
detected during prepurge (until 57.5 seconds), 2K pulls
in, 2K2 opens, 1K drops out, and the system shuts
down; the timer completes its revolution and recycles
the programmer (if 2K dropped out).
—
1K1 closes and 1K2 opens; timer motor starts
(through 1K1, M3A, and M5B); power is applied to
terminal 8, starting the burner motor (blower); 1K3

—
M1B closes, bypassing 1K1; the timer can
complete its revolution if shutdown occurs.
9.5 seconds—M7B opens; running interlocks must be
closed (airflow must be proven) or 1K drops out, 1K3
opens, and ignition trials cannot be started. Running
interlocks must remain closed through the Run period
57.5 seconds—M9A closes; the LS HTR (lockout switch
heater) begins heating in preparation for ignition trials.

(for Two-Stage Switching or Intermittent Pilot/
Ignition of a Nonmodulating Oil Burner)
Ignition Trials
60 seconds—M4A closes; power is applied to terminals 5
and 6, energizing the ignition transformer and pilot
valve (or first stage oil valve solenoid when using two-
stage switching).
NOTE: If using two-stage switching with a second stage
controller, the second stage oil valve solenoid
energizes only when there is a demand for more
heat and the second stage controller contacts close.
—
When a flame is detected, 2K pulls in, 2K2 opens,
and the LS HTR stops heating; 2K1 and 2K3 close.
104 seconds—M5B opens; timer stops with the system in
70 second—M2B opens; pilot or ignition trial ends; a flame
must be detected by this time (2K pulled in and 2K1
closed) or safety shutdown occurs and the lockout
switch trips.
the run condition.
NOTE: Intermittent pilot/ignition and all fuel valves and
solenoids (terminals 6 and 12) de-energize when the
Run period is complete and the main burner
controller contacts open.
—
M2A closes; power is applied to terminal 7,
maintaining power at terminals 6 and 11 (through
the jumpers) until the Run period is completed.
80 seconds—M6B opens: 20 second interrupted pilot/
ignition (terminal 5) de-energizes.
For complete installation, checkout, troubleshooting, and
service information, refer to form 60-0770.
100 seconds—M8A closes; power is applied to terminal
12, energizing the main fuel valve (or second stage oil
valve solenoid when using two-stage switching).
