POWER SUPPLY

CHECKOUT PROCEDURE

1.Turn power switch to the “OFF” position and remove the power pack from cabinet.

2.If air flow switch is installed, locate air flow switch and remove power pack cover. If air flow switch is not installed, go to step 4.

3.Disconnect the three-pin plastic connector and jumper the two female pins (white wire to white-brown wire) as shown in Fig. 23.

4.Place power pack on a well insulated workbench. Connect meter negative (-) lead to the sheet metal chassis and the high voltage probe to high voltage contact on back cover of power pack. Connect AC power to power pack using an extension cord and turn power switch to the “ON” position. Keep hands and tools away from high voltage contact.

5.If Operating Light comes ON and output voltage is between 6100 and 6800 VDC, power supply is good.

6.If voltage is good but Operating Light does not come on, replace Operating Light.

CELL TEST

1.Place collecting cell on a well insulated workbench with the cell contact button pointing upward.

2.Select a power pack (with air flow switch bypassed and ozone reduction jumper intact) that reads be- tween 6100 and 6800 VDC at the cell contact with no cell attached.

3.Place power pack on top of collecting cell ensuring that there is proper contact between the cell contact on the power pack contact.

4.Using a standard extension cord, apply 120 VAC to power pack. Turn power switch to “ON” position.

5.Connect meter negative (-) lead to metal frame of collecting cell. Use high voltage probe to measure voltage at collecting cell ionizer or cell plates. Voltage should be 6100 to 6800 VDC.

NOTE: A new “out-of-box” cell may cause the voltage to be lower than normal for a short period of time. To obtain a more accurate measurement, “age” the cell by applying high voltage to the cell for 15 to 30 minutes.

6If voltage is below 6100 VDC, check cell for foreign objects, bowed/bent/loose plates, broken ionizing wires or cracked insulators. Wash cells if required. If Operating Light remains OFF, replace collecting cell.

AIR FLOW MONITOR TEST

1.Connect a multimeter set to read 120 VAC to power supply terminals marked “LINE.”

2.Connect 120 VAC to power pack plug, turn power switch “ON.”

3.Blow on thermistor at air flow monitor. 120 VAC should appear at multimeter. Stop blowing and volt- age should disappear in 10 - 15 seconds.

4.If voltage did not appear (Step 3), disconnect power to power pack. Locate air flow switch and remove power pack cover. Disconnect the three-pin plastic connector. Jumper the two female pins (white wire to white-brown wire) as shown in Fig. 23. Reconnect power to power pack. Turn power switch “ON.”

A.If 120 VAC appears at multimeter, replace air flow monitor.

B.If 120 VAC does not appear on multimeter, problem is other than air flow monitor. Recheck all primary wiring.

NOTE: The air flow monitor is designed to operate in the temperature range of 65° to 120° F. Operation outside this range is not recommended.
