Burnham V8 Series manual CAD Cell Resistance When Sensing Flame

Page 70

v.T-T Jumper: Select models have pre- installed T-T jumper resistor. To remove, use side-cutting pliers to cut jumper (See Figure 28).

vi.Diagnostic LED: The indicator light on oil primary control provides lockout, recycle and cad cell indications as follows:

•Flashing at 1 Hz (½ second on, ½ second off): system is locked out or in Restricted Mode.

•Flashing at ¼ Hz (2 seconds on, 2 seconds off): control is in Recycle Mode.

•On: cad cell is sensing flame.

•Off: cad cell is not sensing flame.

vii.Cad Cell Resistance Check: For proper operation it is important that the cad cell resistance is below 1600 ohms. During a normal call for heat, once the control has entered the Run Mode, press and release the reset button. Indicator light will flash 1 to 4 flashes. See Table 5 for equivalent cad cell resistance.

3More than 800 and less than 1600

4More than 1600 and less than 5000

b. CHECK OIL PRIMARY CONTROL

CAUTION

Due to the potential hazard of line voltage, only a trained, experienced service technician should perform the following safety checks.

This control contains no field-serviceable parts. Do not attempt to take it apart. Replace entire control if operation is not as described.

i.Preliminary Steps

•Check wiring connections and power supply.

•Make sure power is on to the controls.

•Make sure limit control is closed.

•Check contacts between ignitor and the electrodes.

•Check the oil pump pressure.

•Check the piping to the oil tank.

•Check the oil nozzle, oil supply and oil filter.

ii.Check Safety Features Safe Start:

•Place a jumper across cad cell terminals.

•Follow procedure to turn on burner. Burner must not start, indicator light turns on and control remains in Idle Mode.

•Remove jumper.

iii.Simulate Ignition or Flame Failure:

•Follow procedure to turn on burner.

•Close hand valve in oil supply line.

•Failure occurs, device enters Recycle Mode. Indicator light flashes at ¼ Hz rate 2 seconds on, 2 seconds off).

•Device tries to restart system after approximately 60 seconds.

•After third Recycle Mode trial, safety switch locks out within safety switch timing indicated on label and control enters Restricted Mode. Indicator light flashes at 1 Hz rate (½ second on, ½ second off). Ignition and motor stop and oil valves closes.

•To reset from Restricted Mode: Press and hold the reset button for 30 seconds. When the LED flashes twice, the device has reset.

iv.Cad Cell Check: See Figure 29.
