R4140G, L AND M FLAME SAFEGUARD PROGRAMMING CONTROLS
Table 2. Static Tests of External Devices (Continued).
Normal
Operation
16-L2 Line voltage at terminal 16.
4-L2 Line voltage at terminal 4.
3-L2 1. Burner motor (fan or blower)
starts.
2. Line voltage at terminal 3
within 12 seconds.
— Ignition spark (if ignition
transformer is connected to
terminal 18).
— 1. Ignition spark (if ignition
transformer is connected to
terminal 5).
2. Automatic pilot valve opens
(if connected to terminal 5).
NOTE: Refer to wiring diagram
of the programmer being
tested.
— Same as test no. 6 for
connections to terminal 6. (If
using direct spark ignition,
check the first stage fuel
valve(s) instead of the pilot
valve.)
— Automatic main fuel valve(s)
opens. (If using direct spark
ignition on a model with
intermittent pilot/ignition on
terminal 6, check the optional
second stage fuel valve, if
used.)
— Alarm (if used) turns on.
13-L2 Firing rate motor drives open;
zero volts at terminal 13 after
motor starts driving open.
13-L2 Firing rate motor drives closed;
line voltage at terminal 13 after
motor closes.
15-L2 Firing rate motor drives open;
line voltage at terminal 15 after
motor opens.
If Operation is Abnormal,
Check the Items Listed Below
1. Preignition interlocks are closed. If open,
determine cause(s) and correct the
condition(s).
1. Start interlock(s), if used, is closed. If open,
determine cause(s) and correct the
condition(s).
2. If start interlock(s) is not used, jumper is
installed between terminals 4 and 16.
1. Burner motor circuit:
a. Manual switch of burner motor is closed.
b. Burner motor power supply, overload
protection, and starter are OK.
c. Burner motor is OK.
2. Running or Iockout interlocks (including the
Airflow switch) are closed.
1. Watch for spark or listen for buzz.
a. Ignition electrodes are clean.
b. Ignition transformer is OK.
1. Watch for spark or listen for buzz:
a. Ignition electrodes are clean.
b. ignition transformer is OK.
2. Listen for click or feel head of valve for
activation.
a. Actuator (if used) is OK.
b. Pilot valve is OK.
Same as test no. 6. (If using direct spark
ignition, check the first stage fuel valve(s)
instead of the pilot valve.)
1. Listen for and observe operation of the main
fuel valve(s) and actuator(s).
2. Valve(s) and actuator(s) are OK.
1. Alarm is OK.
1. Low Fire switch is open.
2. Firing rate motor and transformer are OK.
1. Low Fire switch is closed.
2. Firing rate motor and transformer are OK.
1. High Fire switch is closed.
2. Firing rate motor and transformer are OK.
