Item Name Description
1
Electronic/Pneumatic
Enclosure
Allows access to the system electronics and pneumatics.
2 Main Air Inlet Connects the coating system to the facility air supply.
3
Fluid System
Enclosure
Houses the purge valve, circulation valve, pump, filter assembly, fluid
regulator, and fluid heater.
4
Main Power Circuit
Breaker
Controls all electrical power to the entire system including the coating
system and laptop computer.
5 Main Power Inlet
Connects the main power cord from the facility source to the coating
system.
6 Main Air Regulator
Regulates air pressure supplied to the coating system through the main
air inlet.
7 Main Air Gauge
Displays the air pressure to which the main air regulator is set. The
recommended setting is 551 to 620 kPa (80 to 90 psi).
8 Rear EMO
Activating the EMO vents all pressure in the pneumatic system, de-
energizes the robot motors, and cuts power to all system components
except the computer and monitor. Refer to Section 2 - Safety for additional
information.
9
Material Change
Over Panel
Used to switch between a fluid reservoir and solvent reservoir and toggle
the air supplied between the reservoirs. Also houses the circulation valve
and purge valve for the SC-104/105VCS Viscosity Control System.
10
Reservoir Air
Pressure Switch
Three-position switch that toggles the air supplied to Reservoir A, Reservoir
B, or neither.
11
SMEMA Downstream
Connection
Allows for SMEMA communication between the coating system and a
downstream machine such as an unloader.
12
SMEMA Upstream
Connection
Allows for SMEMA communication between the coating system and an
upstream machine such as a loader.

Introduction 1-19
Figure 1-9B Non-Circulating Fluid System
Item Name Description
1 Purge Valve
The Purge Valve is used to purge air out of a circulating fluid system. It
bypasses the Circulation Valve and is generally used at system startup and
after a fluid change.
2 Circulation Valve The Circulation Valve controls the amount of flow of the circulation loop.
3 Pump
The Diaphragm Pump is an air-operated, reciprocating pump. It is a 1:1
pump, operating up to 100 psi. Air pressure to the pump is directly supplied
from the main air supply of the SL-940E/SL-941E Conformal Coating
System.
4 Fluid Regulator
The Fluid Regulator is an air-piloted regulator controlling the fluid pressure
via the software controlled electro-pneumatic air regulator.
5 Filter Assembly
The Filter Assembly blocks small particles in the conformal coating fluid
from clogging the coating applicator.
6 Fluid Heater The Fluid Heater controls the fluid temperature through the ECXP software.
