DESCO CHARGEBUSTER JR. 60500 (01) PDF SUMMARY:

How do air ionizers neutralize static charge?

Air ionization neutralizes static charge on insulated and isolated objects by producing separate charges in the molecules of the surrounding air. When an electrostatic charge is present on objects, it attracts opposite polarity charges from the ionized air.

---

When should ionization be considered as a method for charge neutralization?

Ionizers should be considered for charge neutralization when grounding cannot be achieved.

---

When should ionization systems not be used?

Ionization systems should not be used as a primary means of charge control on conductors or people.

---

What are some examples of process necessary insulators?

Examples of process necessary insulators are the PC board itself, plastic test stands, plastic housing where a PCB may be mounted, as well as computer monitor screens and regular cleaning wipes.

---

What are some examples of floating or isolated conductors?

Examples of floating or isolated conductors are loaded PCB mounted in a stand where the pins are not contacting the dissipative workstation.

---

What should be considered when selecting an ionizer?

When selecting an ionizer, life cycle costs should be considered, including equipment cost, installation cost, and operation and maintenance cost.

---

Where is the unit normally placed?

The unit is normally placed at one end of a workbench or area to be neutralized. It may also be wall-mounted or mounted on a shelf.

---

What is the optimal distance for the ionizer’s decay time (neutralization efficiency)?

The ionizer’s decay time (neutralization efficiency) will be best from approximately 6” to 42” in front of the unit and will drop off as the distance from the unit increases.

---

How do I operate item 60500?

Set the front panel rocker fan switch to either “HIGH” or “LOW” fan speed. Higher airflow will result in a faster neutralization rate. Safety interlock switches are provided internally on the emitter cassette. This ensures that power is cut off in the event that the cassette is removed or not fully installed. Aim the unit so that the maximum airflow is directed at the items or area to be neutralized.

---

How do I operate item 60501?

The bottom rocker switch on the 60501 turns on a heater which will raise the temperature of the output air to about 10°F above ambient. The heater is only to offset the chill factor of the moving air. It is not intended to warm the workstation.

---

What maintenance is required for the Chargebuster Jr. H/O ionizer?

Periodic maintenance will be needed to provide optimum performance. The frequency of monitoring ionizers really depends on how and where they are used. Since the majority of them use a fan to transport the ions to the working area, the cleanliness of the air directly affects their performance over time and how often the emitters should be cleaned.

---

How often should the electrodes be cleaned?

The electrodes should be cleaned at least every six months. However, more frequent cleaning may be required if used in environments with more contaminants.

---

How do I remove the emitter cassette?

1. Switch to the OFF position.
2. Grasp the cassette ejector levers at the center and pivot outward about 90 degrees.
3. Grasping the right and left corners, pull the cassette straight out of the ionizer.
4. The cassette can then be replaced with a spare (item #60480, sold in pairs) or removed to another area for cleaning.
5. Emitter pins are readily accessible and the cleaning of the cassette can be accomplished with a stiff brush or lint-free swab and isopropyl alcohol or other residue-free cleaning solvent.

---

Can an air filter be installed?

Yes, an air filter is included with the unit to be used in place of the unit’s grill in dusty or dirty environments.

---

What are the dimensions of the screen?

The dimensions of the screen are 4-5/8" x 4-5/8" x .15". Construction is 30 x 30 aluminum mesh (30 wires/sq. in. in a crisscross pattern). This filter is easily removed and can be washed in warm, soapy water when it becomes dirty. Replacement filters are available as item #60455.

---

How is the comparative efficiency of bench top ionizers determined?

The comparative efficiency of bench top ionizers is determined by ESD Association Standard S3.1 measuring offset voltage (balance) and both polarities’ discharge times.

---

What tools are required for calibration?

Tools Required: 1. Charged plate analyzer 2. Potentiometer adjustment tool. 3. 9V Battery 4. Digital Multimeter

---

How do I check the Neutral-to-Ground voltage at the outlet?

1. Be sure the multimeter is set on AC Volts (minimum 150-200 volts).
2. Measure between the ground pin and the neutral (should be the wider blade).
3. Voltage must not exceed 3 volts – Ref: National Electrical Code below.
4. If voltage exceeds 3 volts, consult a licensed electrician to correct the problem.

---

How do I adjust the balance?

1. Zero out the charged plate analyzer by pressing the zero button and then adjusting the potentiometer, or knob, on the charged plate itself. (The charged plate should be zeroed every 10 to 15 minutes if working on multiple units). The charged plate needs to be set to the float / decay position.
2. Place the Ionizer twelve inches from the charged plate and turn the unit on.
3. Adjust the balance potentiometer until the unit is 0 to ±10V on the high fan speed. The unit should stay within 0 to ±10V on the low fan speed.

---

How do I adjust the alarm?

1. Turn the alarm potentiometer counterclockwise approximately 10 turns or until you hear or feel that it has reached the end. The unit should be alarming. If the unit is not alarming return to the factory.
2. Turn the alarm back clockwise until it stops alarming.
3. From the point where the unit stops alarming turn the potentiometer three more full revolutions clockwise.
4. Make sure that the charged plate is in the decay/float position and watch the voltage on the charged plate. Apply the 9-volt battery to the front grill and the case simultaneously. The voltage should rise and the unit should START alarming at approximately 100V to 200V. Flip the battery around and repeat for the opposite voltage. If the unit does not alarm at the proper voltage adjust the alarm potentiometer one-half turn clockwise to increase the alarm voltage and counterclockwise to decrease alarm voltage.

---

How do I perform final testing?

1. Check that the balance is still at 0 to ±10V on the high fan speed. If it is not adjust the balance back to within tolerance.
2. Perform decay test on both the positive and negative voltages. To do this press the charge button on the charged plate and allow the plate to charge up over 1000v. Then press the decay button on the charged plate and look at the timer to see how long it takes to decay the charge. The unit should decay the charge in less than 1.5 seconds. Toggle the ± switch and repeat.
3. To test the alarm, apply the 9-volt battery to the front grill and the case simultaneously. Make sure that the charged plate is in the decay/float position and watch the voltage on the charged plate. The voltage should rise and the unit should START alarming at approximately 100V to 200V. Flip the battery around and repeat for the opposite voltage. If the unit does not alarm at the proper voltage adjust the alarm potentiometer one-half turn clockwise to increase the alarm voltage and counterclockwise to decrease alarm voltage.
