R8184M ACTION

Transformer primary is energized if limit switch is closed.

Relay 1 K pulls in, closing contacts 1 Kl and 1 K2. Burner motor, oil valve, and ignition are energized and safety switch heater begins heating.

Safety switch heater is de-energized. Burner operation contin- ues under control of the thermostat and limit.

Relay 1 K is de-energized and contacts 1 Kl and 1 K2 break, stopping the burner and ignition.

Safety switch is heated. If flame is not established within 45 seconds, the safety switch breaks, de-energizing the 1 K relay and lighting the indicator light (if provided). Contacts 1Kl and lK2 break, stopping the burner motor, oil valve, and ignition.

Manual reset of safety switch is required.

Safety switch heater starts. tf flame is not reestablished within 45 seconds, the safety switch opens, de-energizing the 1K relay.

The indicator light (if provided) lights. Contacts 1Kl and lK2 break, stopping the burner motor, oil valve, and ignition. Manual reset of safety switch is required.

Burner shuts down safely and automatically returns to normal operation when cower is restored.

:

The heating system shuts down when the R8184M locks out on safety. Freezeout (i.e., cbld house, frozen pipes) can occur if weather conditions are severe. Models are available with indicator light for lockout indication.

FIRE OR EXPLOSION HAZARD

CAN CAUSE PROPERTY DAMAGE, SEVERE IN-

JURY, OR DEATH

Ensure the combustion chamber is free of oil or oil vapor before starting the system.

1. Open the hand valve in the oil supply line.

2.Ensure the system is powered. Check the circuit breaker or fuse and close the system switch, if provided.

3. Push in and release the red reset button.

NOTE: If the safety switch has just locked out, the safety switch may need a minute to cool down before it can be relit.

4. Set thermostat to call for heat.

5.Oil burner should light and operate until the call for heat ends.

CHECK SAFETY FEATURES

Simulate flame failure:

1. Follow the starting procedure to turn on the burner.

2. Close the hand valve in the oil supply line.

3.Safety switch should lock out in approximately 45 seconds. The indicator light, if provided, should light.

Ignition and motor should stop and oil valve should close.

4. Restart system.

Simulate ignttlon fallure:

1. Follow the starting procedure to turn on the burner, but do not open the oil supply hand valve.

2. The safety switch should lock out in approximately45 seconds. Indicator light, if provided, should light. Ignition and motor should stop and oil valve should close.

3. Restart system.

Simulate power failure:

1. Turn on the main burner following the starting proce- dure.

2. Disconnect power supply. Main burner should shut off.

3. Reconnect power supply. Main burner should turn on. lf system does not operate as described, proceed to

Burner Motor Does Not Start When Thermostat Calls

For Heat

PRELIMINARY CHECKS

1. Make sure limit switch is closed and that contacts are clean.

2. Check for line voltage power at the oil primary. With thermostat calling for heat, voltage between black and white leadwires on oil primary should be 120 Vat.

CORRECTIVE AC ION

BURNER STARTS

Trouble is in thermostat circuit. Check thermostat and wiring connections.

BURNER DOESN’T START

Trouble is in cad cell or oil primary. Go to step 2.

Cad cell is seeing external light, is defective, or cad cell connections

Go to step 3. are shorted.

Eliminate external light source or permanently shield cad cell.

Disconnect power; check all wiring connections. Tighten any loose connections, if necessary, and retest.

If burner motor and ignition still don’t start, replace oil primary. lf ignition is on and burner motor is off, check burner motor and wiring connections to motor. Replace burner motor, if necessary.

Replace cad cell with Part No.

Burner Motor Starts But Flame Is Not Established

Check burner and ignition transformer per manufacturer’s recommendations. This is not an oil primary or cad cell problem.

Burner Starts, Flame Is Established; Then Burner Locks Out On Safety

PROCEDURE

1. a. Reset safety switch by pushing red reset button. b. Disconnect cad cell leadwires at oil primary. c. Jumper thermostat terminals to start burner: l

Jumper low volt thermostats at oil l primary.

Jumper line volt thermostats at thermostat. d. After flame is established, but before safety switch locks out, short cad cell by jumpering F-F terminals.

2. a. Disconnect line voltage power and reconnect cad b. cell F-F terminals.

Unplug cad cell and clean face with soft cloth. Check sighting for clear view of flame. Replace cell in socket.

C. Reconnect line voltage power. Reset safety switch by pushing red reset button, and jumper thermostat terminals to start burner: l

Jumper low volt thermostats at l oil primary.

Jumper line volt thermostats at thermostat.

3. Reset safety switch and restart burner.

T

CORRECTIVE ACTION

BURNER LOCKS OUT

Oil primary control is defective-replace. If there is any doubt that F-F terminals were jumpered within safety switch timing, wait 5 minutes, then repeat procedure

(steps 1 a-l d).

Replace cad cell with Part No.

130367, go to step 3.

BURNER KEEPS RUNNING

Check cad cell with ohmmeter, see Cad Cell Troubleshooting table on page 9. If ohmmeter is not available, go to step 2.

Cad cell is okay.

Check cad cell view of flame, flame shape, and oil nozzle.

If flame is normal and cad cell has good view of flame, check for open circuits in socket assembly wiring. Replace assembly, if necessary.a

Cad cell and socket assembly are okay.

“If cad cell is okay and oil primary appears okay but system continues to lockout on safety, repeat steps 1 a-l d using a2700 ohm resistor to jumper F-F terminals. Burner will lock out if oil primary is defective; replace oil primary, if necessary.

e

CAD CELL TROUBLESHOOTING

Checkcad cell by reading resistance with ohmmeter while flame is present. See the table belowforcause and corrective action to be taken for resistance that is read.

OHMMETER READING

Over 1600 ohms, but not infinite.

Infinite resistance.

CAUSE

Short circuit.

Cad cell and application are operating correctly.

Dirty cad cell.

Improper cad cell sighting.

Improper air adjustment.

Defective cad cell.

Recheck oil primary using a

2700 ohm resistor to jumper F-F terminals; repeat steps

Flame is Established” on page 8.

Clean cad cell face and recheck.

Check flame sighting.

Adjust air band to get good reading.

Replace cad cell with Part No. 130367 and recheck.

Check for improper wiring, loose cad cell in holder, or defective cad cell.

Replace defective cad cell with Part

TRIP SAFETY SWITCH BEFORE OPERATING

BURNER MAINTENANCE (Tradeline model only)

PUSH LEVER DOWN TO

TRIP SAFElY SWITCH

TrIppIng the safety switch shutsdown the burner but does not disconnect the power supply. Turn off power at system switch or circuit breaker before servicing the control system, burner motor, oil valve or ignition to avoid electrical shock.

To trip the safety switch, move the safety switch lever down until the red reset button pops out and the indicator light comes on. See Fig. 5. Burner will not operate until safety switch is reset by pushing in the red reset button. WHEN SAFETY SWITCH TRIPS
