1 Introduction Overview This manual describes the installation, operations, and maintenance of the Fan Width Control (FWC) system. The FWC system is used with the Asymtek Century Series C-740 (conveyor) or C-741 (batch) dispensing systems. The FWC system controls the dispenser fan spray pattern using the Easy Coat for Windows NT (ECNT) software. CAUTION! Installation, operation, and service should only be performed by Asymtek-trained operators and service technicians.
Sensor Fixture The Sensor Fixture mounts to the conveyor rail or other convenient location and includes the Sensor, Drain Pan, and Drain Pan Mounting Plate as shown in Figure 1-1. Sensor Fixture components function as follows: • Fan Sensor: The Fan Sensor consists of a fiber optic emitter and receiver. The emitter sends a light beam to the receiver that detects the intensity of the light beam. Each sensor is clamped onto the Sensor Bracket. The Fan Sensor cables connect to the Fan Width Enclosure.
Fan Width Enclosure The Fan Width Enclosure is a remote enclosure that sits on top of the dispensing system or other convenient location. It is connected between the Sensor Fixture and the Robot Controller. The Fan Width Enclosure contains the electronic components for the Fan Width Control. See Figure 1-2 and Figure 1-3. The operator controls can be accessed on the front panel behind the window. Each of the components of the Fan Width Enclosure is described below.

Figure 1-3 Fan Width Enclosure (Rear View) Software Description The Fan Width is controlled through the Easy Coat for Windows NT (ECNT) interface. The software is described in detail in the Easy Coat for Windows NT Help file.
2 Installation Overview If the Fan Width Control System was included as an option with the purchase of your dispensing system, most of the installation process will already be complete. The sensors and the Fan Width Enclosure will still need to be installed. This section covers the installation of the Sensor Fixture and the Fan Width Enclosure, and the setup of the ECNT Software. WARNING! CAUTION! The installation should be performed only by Asymtek-trained personnel.
6. Using the 3-mm hex key, tighten the locking screws to lock each sensor in place. > Do not overtighten. Tighten only until the screw stops turning. 7. Place one of the protective lenses in front of each sensor. > The protective lenses keep the sensors from getting coating material on them. 8. Cover the Sensor Brackets with the Sensor Covers. See Figure 2-1. Make sure the holes in the covers line up with the holes in the brackets.
9. Install the protective tubing over the sensor cables. 10. Route the fiber optic lines to the Fan Width Enclosure. 11. Use a tie-wrap to secure the fiber optic cables and tubing to the Drain Pan Mounting Plate. See Figure 2-1. 12. Using the M4 screws provided and the 2.5-mm hex key, attach the Drain Pan Clamps to the Drain Pan Mounting Plate. Do not tighten the clamps at this time. 13. Place the Drain pan in the Drain Pan Bracket. 14. Attach the Drain Tube to the outlet on the bottom of the Drain Pan. 15.
Installing the Fan Width Enclosure Tools and Materials Needed • Phillips head screwdriver Refer to Figure 2-2 and the Specifications section of this manual for Fan Width Enclosure installation. To install the Fan Width Enclosure: 1. Turn OFF power to the dispensing system. 2. Locate the orange connectors on the rear panel of the dispensing system and connect the orange connectors of the Control Wire Harness as shown in the Specifications section of this manual. 3.

Figure 2-3 Dispensing System Rear Panel Installing the FWC Software The software is already installed when ECNT is installed on the dispensing system computer. The Fan Width Control set-up will need to be performed prior to operation and is described in the ECNT Online Help file.
3 Operation Overview WARNING! Allow only Asymtek-trained personnel to perform the following tasks. Follow the safety instructions in this document and all other related documentation. This section describes the operation of the FWC system after the initial installation on the dispensing system. ? NOTE Initialization and Calibration is an integral part of Operations.
Initialization and Calibration This section describes the steps used after initial installation, changing materials, or cleaning/replacing components. To start this process, turn ON the dispensing system if it is not already on. Testing Sensor and Amplifier Connections The following steps describe how to test the FWC and make sure that it is functioning properly and communicating with the ECNT software. 1. If ECNT is not running, start ECNT now. 2.

Setting the Fiber Optic Fan Sensor Sensitivity The following steps describe how to calibrate the sensitivity of the Fiber Optic Sensor Amplifier in the Windows environment. ? NOTE The Fiber Optic Sensor Amplifier settings should be as follows: Switches: D.ON Received Light Intensity: No “P” after the number on the display.
9. Using the Up-Down arrow button, set the trigger value to 90 to 100 less than the “no obstruction” value recorded in the “Testing Sensor and Amplifier Connections” procedure above. 10. The next step is to test the spray pattern detection. > If an APPLIC ON/OFF button is on the dispensing system front panel, use it to turn the dispenser ON and OFF.
Setting the Fan Width Windows Follow the ECNT Help File on setting, controlling, and measuring the fan width. Pressure Controller The Pressure Controller offers two modes of operation--Automatic and Manual. The Controller’s keypad is accessed in the Fan Width Enclosure by removing the clear front window. Software on the Controller is factory installed. When the Pressure Controller is energized, there should be information on the display if it is working properly.
Pressure Controller Function Test Perform the following test to ensure that the Pressure Controller is functioning properly. Refer to Figure 1-2 for key locations on the Controller Keypad. 1. Press F1 to enter Manual Mode. 2. Press the Up key to increase pressure in small increments. > If the pressure transducer fails to respond, check the connections between the robot and the pressure transducer. 3. Press the Down key to decrease pressure in small increments. 4.
4 Maintenance WARNING! Allow only Asymtek-trained personnel to perform the following tasks. Follow the safety instructions in this document and all other related documentation. Overview The Fan Width Control system requires Periodic Maintenance for efficient operation. Perform the following tasks as indicated. A Parts subsection is also included for ordering replacement parts. ? NOTE CAUTION! Refer to your specific dispensing system manuals for dispensing system maintenance instructions.
