Grounding

WARNING: Operating faulty electrostatic equipment is hazardous and cancause electrocution, fire, or explosion. Make resistance checks part of yourperiodic maintenance program. If you receive even a slight electrical shockor notice static sparking or arcing, shut down all electrical or electrostaticequipment immediately. Do not restart the equipment until the problem hasbeen identified and corrected.

Grounding inside and around the booth openings must comply withEN50050-2, EN50177, EN16985, latest conditions.

� All electrically conductive objects in the spray areas shall be electrically

connected to ground with a resistance of not more than 1�megohm asmeasured with an instrument that applies at least 500�volts to the circuitbeing evaluated.

� Equipment to be grounded includes, but is not limited to, the floor of the

spray area, operator platforms, hoppers, photoeye supports, and blow‐offnozzles. Personnel working in the spray area must be grounded.

� There is a possible ignition potential from the charged human body.

Personnel standing on a painted surface, such as an operator platform, orwearing non‐conductive shoes, are not grounded. Personnel must wearshoes with conductive soles or use a ground strap to maintain aconnection to ground when working with or around electrostaticequipment.

Operation


1. Before starting your powder coating system, make sure of the following:

All air tubing, transfer hoses, vent & waste hoses and electrical cables aresecurely connected.

All doors are correctly installed and closed/clamped to the housing.

2. Turn on the system compressed air supply and electrical power.

3. Start the booth exhaust fan. In most systems, this will start the sieve motor.

4. Set the sieve air pressures and flow rates.

Sieve Configurations Fine Pressure Valve Restriction Valve Festo VA ¼” Air in Nl/min

All 360 Assemblies 2 bar 5 (4.75) cycles open 180 - 200

All 650 Assemblies 2 bar 5.25 cycles open 250 - 280

5. Adjust the vent-assist air pressure.

6. Apply the following settings:

Mini Cyclone - 1.5 - 2 bar (application depending)

Hopper fluidisation - 1.5 - 2.5 bar (application depending)

Sieve seals - 2 bar

NOTE: Check the air regulator and restriction valve settings when you startthe system. Check the restriction valve periodically during the day to makesure air is being supplied to the bearings. Check the bearings for powderwhen you are cleaning the sieve. If the lip seals are undamaged, but powderhas contaminated the bearings, increase the purge air pressure.

Air quality must be according to ISO 8573.1 Class 1:4:2

Incoming air pressure must not exceed 7 bar ,maximum.

Maintenance


NOTE: Maintenance procedures given here are for the general assemblyonly. Refer to your system component manuals for maintenance proceduresfor all other system equipment. For all maintenance requirements of therotary sieve, please refer to the AZO E360B technical manual; this can besupplied by Nordson upon request.

Daily Maintenance Note: You may need to perform these procedures more or less often,depending on your application requirements.

Component Maintenance Procedure

Cables, Tubing, andFeed Hoses

Check all external cables, powder hoses, and air tubing for damage. Repair orreplace as necessary

HDLV Transfer Pumps Purge the pumps. Inspect the pinch valve body for signs of powder leakage. Ifpowder is present in the pinch valve section, replace the pinch valves. Refer tothe Prodigy HDLV High-Capacity pump manual for repair procedures

Powder Supply Check the powder supply level regularly and add powder as necessary

Compressed Air Supply Check the compressed air dryers and filters. Drain filters if needed. Performmaintenance as necessary

Enclosure Clean the interior and exterior of the Rotary Sieve Assembly. Check allequipment ground connections

Venting Check and clean sieve and hopper venting hoses

Hopper Check hopper fluidisation is correct. Gently simmering evenly.

Periodic Maintenance Note: You may need to perform these procedures more or less often,depending on your application requirements.

Component Maintenance Procedure

Compressed Air System Open the drop leg and use a clean, white cloth to check for contaminants.Correct any problems immediately. Drain the air filters and change theelements as necessary.

Electrical System Tighten all electrical connections and inspect tor loose or broken wires. Checkthe electrical system tor electrical safety every 12 months. The system mustcomply with all local, state, and federal codes.

System Grounds Check all equipment grounds. Electrical equipment must be groundedaccording to the relevant code. For maximum transfer efficiency and safety,electrostatic equipment must be grounded to provide a complete circuit fromthe product, through the hangers, conveyors booth and back to the guncontrollers.

Refer to Grounding in the Safety section of this manual and to publicationnumber TCTT-06-3881 on the Nordson emanuals website(http://emanuals.nordson.com/finishing) for more information on powdercoating system grounding.

Air Tubing Pressurise the system and identify if there any air leaks. Replace or repair anydamaged fittings or tubing.

Troubleshooting


These troubleshooting procedures cover only the most common problems. Ifyou cannot solve a problem with the information given here, contact yourlocal Nordson representative for help.

Problem Possible Cause Corrective Action

1. Good powder in thewaste container

Powder feed rate exceeds sievecapacity

Reduce the venturi transfer-pump airpressure. If a HDLV system, contactyour Nordson representative.

Erratic or pulsating feed rate.Heavy surges may exceed sievecapacity

Check the transfer-pump air supplyand pressure. Check the transferpumps, pickup tubes, and hoses forblockages. Check the fluidising platesand the powder in the colour modulehoppers for contamination.

Too many oversized particles inreclaimed powder

Check the powder in the colourmodule for contamination

Screen mesh is too fine Change to a more coarse screenmesh. Refer to AZO E360B technicalmanual for procedure.

Loose screens Remove the screen frame from thesieve. Adjust the screen tensionaccording to the AZO E360Btechnical manual.

Clogged screens Clean or replace the screen. Checkthe powder for contamination. Addnew powder to the hopper. Too largea ratio of reclaimed-to-new powdercan cause clogging.

Vent-assist air pressure too low, orhose to scrap container and/orcontainer not air tight

Adjust the vent-assist air pressure.Check the hose and scrap containerconnections and seals.

Sieve not level, discharge endpitched down

Level the sieve and/or the feedhopper.

2. Powder backing up inthe accumulator

Restriction in sieve and/or powderpath causing blockage

Clean the powder path

Vent-assist air pressure too high Adjust the vent-assist air pressure

Repair Contact your Nordson representative for repair information.
