1-2 Safety
Personal Safety
To prevent injury follow these instructions.
• Do not operate or service equipment unless you are qualied.
• Do not operate equipment unless safety guards, doors, or covers are intact and
automatic interlocks are operating properly. Do not bypass or disarm any safety
devices.
• Keep clear of moving equipment. Before adjusting or servicing any moving equipment,
shut o󰀨 the power supply and wait until the equipment comes to a complete stop. Lock
out power and secure the equipment to prevent unexpected movement.
• Relieve (bleed o󰀨) hydraulic and pneumatic pressure before adjusting or servicing
pressurized systems or components. Disconnect, lock out, and tag switches before
servicing electrical equipment.
• Obtain and read Material Safety Data Sheets (SDS) for all materials used. Follow
the manufacturer’s instructions for safe handling and use of materials, and use
recommended personal protection devices.
• To prevent injury, be aware of less-obvious dangers in the workplace that often cannot
be completely eliminated, such as hot surfaces, sharp edges, energized electrical
circuits, and moving parts that cannot be enclosed or otherwise guarded for practical
reasons.
Fire Safety
To avoid a re or explosion, follow these instructions.
• Ground all conductive equipment. Use only grounded air and uid hoses. Check
equipment and workpiece grounding devices regularly. Resistance to ground must not
exceed one megohm.
• Shut down all equipment immediately if you notice static sparking or arcing. Do not
restart the equipment until the cause has been identied and corrected.
• Do not smoke, weld, grind, or use open ames where ammable materials are being
used or stored. Do not heat materials to temperatures above those recommended
by the manufacturer. Make sure heat monitoring and limiting devices are working
properly.
• Provide adequate ventilation to prevent dangerous concentrations of volatile particles
or vapors. Refer to local codes or your material SDS for guidance.
• Do not disconnect live electrical circuits when working with ammable materials. Shut
o󰀨 power at a disconnect switch rst to prevent sparking.
• Know where emergency stop buttons, shuto󰀨 valves, and re extinguishers are
located. If a re starts in a spray booth, immediately shut o󰀨 the spray system and
exhaust fans.
• Shut o󰀨 electrostatic power and ground the charging system before adjusting,
cleaning, or repairing electrostatic equipment.
• Clean, maintain, test, and repair equipment according to the instructions in your
equipment documentation.
• Use only replacement parts that are designed for use with original equipment. Contact
your Nordson representative for parts information and advice.

Safety
Grounding
WARNING:Operating faulty electrostatic equipment is hazardous and can cause
electrocution, re, or explosion. Make resistance checks part of your periodic mainte-
nance program. If you receive even a slight electrical shock or notice static sparking or
arcing, shut down all electrical or electrostatic equipment immediately. Do not restart the
equipment until the problem has been identied and corrected.
Grounding inside and around the booth openings must comply with NFPA requirements
for Class II, Division 1 or 2 Hazardous Locations. Refer to NFPA 33, NFPA 70 (NEC
articles 500, 502, and 516), and NFPA 77, 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 as measured with an instrument
that applies at least 500 volts to the circuit being evaluated.
• Equipment to be grounded includes, but is not limited to, the oor of the spray area,
operator platforms, hoppers, photoeye supports, and blow-o󰀨 nozzles. 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, or wearing non-
conductive shoes, are not grounded. Personnel must wear shoes with conductive
soles or use a ground strap to maintain a connection to ground when working with or
around electrostatic equipment.
• Operators must maintain skin-to-handle contact between their hand and the gun
handle to prevent shocks while operating manual electrostatic spray guns. If gloves
must be worn, cut away the palm or ngers, wear electrically conductive gloves, or
wear a grounding strap connected to the gun handle or other true earth ground.
• Shut o󰀨 electrostatic power supplies and ground gun electrodes before making
adjustments or cleaning powder spray guns.
• Connect all disconnected equipment, ground cables, and wires after servicing
equipment.
Action in the Event of a Malfunction
If a system or any equipment in a system malfunctions, shut o󰀨 the system immediately
and perform the following steps:
• Disconnect and lock out system electrical power. Close hydraulic and pneumatic
shuto󰀨 valves and relieve pressures.
• Identify the reason for the malfunction and correct it before restarting the system.
Disposal
Dispose of equipment and materials used in operation and servicing according to local
codes.

Section 2
Overview
Introduction
See Figure 2-1. The Encore™XL powder feed center conditions and supplies powder
for up to 36 Venturi pumps. It contains a sieve, hopper table, lance and lift assembly,
Venturi-type in-line powder pumps, level sensors, purge manifold, dust collector, fan, and
electrical and pneumatic controls.
The feed center provides quick color changes and automatic purge cleaning. Powder
is drawn from a box or uidized hopper powder source by the lance-mounted, in-line
powder pumps. The powder is then delivered through feed hoses to the spray guns.
The feed center can be equipped with up to 36 Venturi pumps, and is furnished with a
vibratory table to aid in the uidization of powder in boxes.
The feed center controls are designed to accommodate one to two HDLV®reclaim pumps
to transport over-sprayed powder from the powder recovery system to the feed center,
and an optional HDLV pump to transport virgin powder to the system as needed.
Figure 2-1 Powder Feed Center

1607027-01
2-2 Overview
Introduction cont...
Both HDLV transfer pumps deliver the powder to the vibratory sieve, where it is
conditioned before delivery to the powder spray guns. The sieve is equipped with a 20
mesh ultrasonic sieve screen. Other screen sizes are available as an option.
The color change operation is partially automatic. At the start of a color change, the
lances are raised out of the powder source so they can be removed from the feed center.
Then, when the operator initiates the gun purge, the lances are automatically lowered
onto a purge manifold assembly and clamped in place. High-pressure purge air is then
pulsed through the lances, in-line powder feed pumps, hoses, and guns to clean them
of powder. The reclaim and virgin HDLV transfer pumps are purged manually when the
operator is ready.
The Encore XL Powder Feed Center has an integrated air extraction system that provides
a constant airow through the feed center enclosure, preventing powder from escaping
into the spray room. The extraction system includes an exhaust fan, 3 cartridge lters, 3
pulse valves and controls, and nal lters.

Overview
Lance Assemblies
Two, three, or four lance assemblies are attached to the lift assembly. Up to nine in-line
powder pumps can be mounted on each lance assembly. The pumps are installed in the
lance ports, and held into place with a retaining rod. If a lance pump port is not used, it is
plugged with a plug module.

Lift Assembly
The lift assembly uses a locking air cylinder to raise and lower the lance assemblies in
and out of the feed hoppers or powder boxes:
• If a feed hopper is selected as the powder source, the lance is lowered until it is a set
distance above the uidizing plate, as determined by the position of a proximity sensor
on the lift cylinder.
• If a powder box is selected, the lance is lowered until the level sensor on the lance
contacts the powder, and then lowered gradually as the powder is used.
The cylinder motion and locking action are controlled by three solenoid valves that are
part of the control manifold on the roof of the feed center.
The lift cylinder has a spring-actuated locking mechanism released by air pressure. The
cylinder is locked when the air line is vented; unlocked when pressurized. The cylinder
also uses a balancing air circuit, which applies air pressure to both sides of the piston to
prevent lurching when restarting motion after a locked stop.

1607027-01
2-6 Overview
Lift Assembly (contd)
When the cylinder moves the lance up, the lance down circuit is vented, allowing the
lance up circuit air to push the piston up. When the cylinder moves the lance down, the
lance up circuit is vented, allowing the lance down circuit air to push the piston down.
The ow control valves installed in the cylinder air ports control the travel speed of the
piston rod. Three proximity sensors mounted on the cylinder sense when the cylinder
piston is in the hopper, box empty, or purge positions.

Level Sensor Modules
Lance Mounted Level Sensor Function
When the powder source switch is set to Hopper, the lance is lowered down into the
powder in the hopper to the position determined by the hopper proximity switch on the
lift cylinder. The hopper level sensor is positioned to maintain the desired level of powder
in the hopper, turning on and o󰀨 the virgin transfer pump as the powder level rises and
falls. If the level sensor detects a low powder condition for greater than 3 minutes (eld
adjustable), the low powder alarm is turned on.
When the powder source switch is set to Box, the lance is lowered until the box level
sensor contacts the powder. When the powder level falls below the level sensor, the
lance is lowered further into the box. The box proximity sensor on the lift cylinder
prevents the lance from crashing into the bottom of the box.
See Figure 2-6. To adjust the position of each level sensor for the application, loosen the
clamp screw (4) with a hex key.
