Table 2-2 System Controls
Item Equipment Description
2 Motor starter panel Houses motor starters and overload protectors, transformers,
interlock relays, differential-pressure switches, pulse valve
timers, and basic system controls and indicator lights. An
optional programmable controller can be installed in the panel.
3 Flame detector
indicator/relay panel
Provides visible and audible fault and fire alarms and process
shutdown relays. If a detector senses a flame, the interlock
relays shut down the conveyor, booth exhaust fan,
compressed air and electrical power to the spray guns.
ANSI/NFPA-33 standards require flame detectors in all
systems equipped with automatic spray guns.
5 Pneumatic panel Houses air-pressure regulators and gauges for the color
module, differential pressure switch gauges, feed hoppers,
transfer pumps, and other pneumatic equipment.
6 Fan damper control Opens and closes the fan damper louvers to control air flow
through the enclosure. (Used only on Horizon 400.)
8 Pulse air controls Regulate the pulse air pressure and volume. Controls include
a regulator, pressure gauge, and gate valve.
11 Feed-hopper level
sensor
Monitors the level of powder in the feed hopper. Turns on the
transfer pumps when the level of powder falls below the
sensor.
17 Flame detectors Monitor the enclosure (booth) interior for flames. The
detectors use IR sensing technology and provide
through-the-lens self test to check for powder build-up.
Application Equipment
Item numbers in Table 2-3 correspond to callouts in Figure 2-2.
Table 2-3 Application Equipment
Item Equipment Description
4 Gun control units Control air pressure to the powder pumps. Generate
(cable-fed units) and control electrostatic voltage. Each spray
gun requires a control unit. An equipment cabinet houses the
automatic gun control units, a master control unit, and air
supply controls.
9 Automatic spray guns Charge powder particles electrostatically and spray them
toward the grounded workpieces. The operator uses a
manual spray gun for touch-up work.
12 Feed hopper Stores and fluidizes the powder supply for automatic and
manual spray guns.
13 Powder pumps Pump powder out of the feed hopper to the spray guns. Each
spray gun requires a pump.
