2.2. Function of the different parts
2.2.1. TRP 500 flat spray
2.2.2. Manifold block
The manifold supports and connects each atomizing head (one or two heads, depending on the model:
TRP 501 or 502).
• The manifolds have ducts for atomizing air, control air, paint and the HV supply. The manifolds
include a paint inlet, a paint dump outlet, four air inlets fitted with plastic connections and an HV
connector. The following air intakes are fitted:
• pilot trigger, marking (
PT
),
• pilot dump, marking (
PD
),
• Atomizing air (for the fan spray) or directional air (for the round spray), marked (AA),
• Fan air (for the fan spray) or vortex air (for the round spray), marked (FA)
• A paint dump control micro-valve is fitted into the manifold
The valve remains closed until the air in its control circuit is pressurized. When the air is pressurized, the
valve opens and the paint flows into the dump hose
.
In the TRP 502 version, the air and paint feeds are common to both atomizing heads.
2.2.3. High voltage unit UHT 156 EEx e
Receives a low voltage supply that it converts into high voltage for charging the atomized paint particles
