Conveyor Components IR Heater- w/ J Sensor Gear Motor Belt Belt Aligner Front Pulley Belt The conveyor belt is made of Teflon coated fiberglass. It is joined together with an alligator lace using a steel pin to connect each side. The belt will not burn under normal conditi ons but the dryer should always have t he belt moving while the heaters are above 300 °F(149° C). The belt should remain tracked in the center of each pulle y. (See fiBelt Installation and Trackingfl for adjustment instructi ons.) Aligner The aligner is a device for tracking the belt and keeping it on t he pulley. As the belt moves from side to side the aligner is used for ad-justments to keep it centered. The belt does not have to be perfe ctly centered on the pulley but should not be hanging over eit her edge. LittleRed-X1 and X2 come standard with an aligner roller. Pulley The pulleys at either end of the conveyor are made by VASTEX of 4 ½ inch tubing with ¾ inch center shaft. They are mounted on self aligning flange bearing blocks for precision rolling. Gear Motor A 90 or 130 Volt DC gear motor is located to the rear of the conveyor. It drives the rear pulley and belt with a roller and a # 25chain(standard drive) or #35chain(HD dr ive). Replacement part numbers c an be found on the wiring diagram. IR Heater The infrared heaters in VASTEX dryers emit m edium wave infrared heat, perfect for curing many types of inks. The heater connect ions are located in the trough on the right side of the heater, connect ed with high temperature terminals and stainless steel socket head cap screws. (See Wiring Diagrams for Heater Specs) J Sensor The sensor is mounted under the heating elem ent, on the side closer to the control panel, with a shield beneath it. On X2 model s, the sensor is on the rear heater. The sensor is wired to the temperature controller using two wires, a red (positive) and a white ( negative). They must be attached to the proper terminals on the cont roller. Refer to wiring diagra m when replacing fiJfl Sensor.

DC Volt Meter: Digital Volt Meter displays, in volts, the amount of power going to the belt motor. A table show- ing the time associated with voltage can be found in Dryer Operation. Belt Speed Control: An AC-DC converter, mounted to the face of the control panel, allows the operator to vary the belt speed / DC volts to the motor. The dial is for reference only and does not represent seconds in the heat. Control Output Light: This light should cycle on & off with the controller, indicating output signal to relay. System Switch: Sends power to Controls. Shut off power at main disconnect before servicing, Power Light must be out before entering any part of this machine Power Light: It is wired to the line cord and/or the Shut Off Switch and will be illuminated whenever power is coming into the unit. At the end of the day, the machine should be disconnected so this light is out. Temperature Control: See Dryer Operation for more information Heat Switch: Controls power to heater only. Relay Output Light: This 250 volt RED pilot light is wired to the output side of the relay. This light will cycle on & off with the control output light. It verifies that the relay is working properly. Controls Shut Off Switch Machines that are direct wired by the end user are equipped with a shutoff switch. This is the main junction block for incoming power, and is used to restrict access to the control box while it is live. The shutoff must be in the OFF position to enter the control box. START Controls (LittleRed-X2D/X3D) Controls between all LittleRed-X Models are si milar. Refer above for all unlisted controls. BOOST Zone Temp Control: Controls Temperature of Boost Zone. Must be set to the same temperature OR HIGHER than the MAIN Temperature control. MAIN Temp Control: Controls Temperature of MAIN heat zone. BOOST Heat Switch: Controls power to BOOST zone only.

Zone fiRearfl Zone fiRearfl on your LittleRed-X2 is the rear heater. Zone fiRear on your LittleRed-X3 is the middle and rear heaters. On the c ontrol panel, Zone fiRearfl heat is turned on and off with the BOTTOM toggle switch labeled fiRearfl. When operating your LittleRed, Zone fiRearfl must be used. Zone fiRearfl has the temperature sensor attached to it, and controls the heat for both heaters. Use only zone fiRearfl if you are running the dryer slower, and want to conserve on energy costs. Zone fiFrontfl Zone fiFrontfl on your LittleRed-X2 is the Fron t Heater. On the control panel, Zone fiFrontfl heat is turned on with the TOP toggle switch labeled fiFrontfl. The Relay and Heater lights next to the fiFrontfl switch show its operation. The temperature control measures the heat under Zone fiRearfl only. Zone fiRearfl MUST be on to run zone fiFrontfl Zone fiFrontfl requires an average of 15 minutes to heat up to 750°F (400 °C) . Zone Control X2/X3 Zone Control X2D/X3D Zone fiBOOSTfl Zone fiBOOSTfl on your LittleRed X2D or X3D is controlled indepen dently. This Zone is used to superheat your garments on the way into the chamber. Typically, the lo nger your garment is in the chamber, the lower this BOOST zone can be set. Setting the BOOST to 1100F+ is recommended for cure times at or below 60 seconds. Setting the BOOST to 800F+ is recommended for cure times between 2 and 4 minutes Zone fiMAINfl Zone fiMAINfl on your LittleRed X2D or X3D is controlled ind ependently. This Zone encompasses 85%(X2D) or 90%(X3D) of your cure time. If you are running plastisol or other non-specia lty items, you may set the BOOST and MAIN zones to the same temp. The dryer will perform similar to other infrared dryers when BOOST and MAIN zones are set the same. Setting the MAIN to 650F + is recommended fo r cure times at or below 60 seconds. Setting the MAIN to 500F + is recommended for cure times between 2 and 4 minutes BOOST ZONE CONTROL BOOST ZONE DIAGNOSTICS MAIN ZONE DIAGNOSTICS MAIN ZONE CONTROL

Set the Belt Speed : Rotate the Belt Speed Control Knob clockwise to increase speed and counter-clockwise to decrease it. Refer to the charts on the next page for fiTime Through Chamberfl settings. For Plastisol inks, a good starting point is 20-25 seconds in the chamber. Set the temperature: With the power on, push and hold the up arrow, th e (SV) will climb. The longer you hold the button, the faster the (SV) will climb, it will start climbing by one, then ten, then hundreds. Set the desired temperature and allow approximat ely 15 minutes for heat up. Refer to the trouble shooting section for Controller Error Messages. Curing Plastisol with infrared: Plastisol ink can fully cure in approximately 20-30* seconds. T he ink must achieve 310°-320° F (154°-160°C) to cure and fuse t o the garment. We recommend* a starting temperature 800°F (400 °C) , 3fl heater height, and 25 seconds in the chamber. Discharge or water based: Water based products require more time than plastisol to cure due to the fact that the water/moisture must be evaporated befor e the ink can cure. We have seen cure times from 50 to 90* seco nds to achieve a full cure or discharge and not damage the gar- ment. Please note as the time is increased the temperatur e must be decreased to protect the garment from scorching. *Actual cure times can vary depending on conditions such as garment moisture an d color, ink color, ink thickness, and environmental conditions. All three variables should be used to maximize production while insuring a proper cure. How to determine Temperature set point: The sensor is located directly under the heater so it will read a much higher tem perature than seen at the garment. Set the te m-perature several hundred degrees higher to compensate for this difference. A non contact heat gun can be used to read the temperature of the ink at the e nd of the dryer while it is still under the last heater. Take into consideration the thickness o f the ink when using the heat gun. It will measure the top layer of the ink. If the ink is very thick you must add a buffer to be sure cure temperature is reached throughout the ink. Temperature set point, heater distance to the garment, and belt speed will all effec t the ink temp. Turn on Heat Switch : Turn on the temperature controller and set desired temperature. Set the Heater Height : Using the knobs on the side of the dryer, Raise or lower each side of the heater(s) to desired height. Loosen the knob, raise or lower it to the desired height, then tighten. Use the individually height adjustable haters to tune in your required heat profile. Main Disconnect : Turn on System Switch : Power is sent to the heater switch, belt speed control and the powered exhaust blower turns on. Turn on Conveyor : Set speed to desired setting. Check belt path: Remove any objects from the conveyor and belt. Turn on Power on The red Power Light will illuminate. The LittleRed should be wired to a Main Power Disconnect. (Optional) Disconnect bracket available. Control System Summary: The control system in your dryer is called a ficlosed loop sy stemfl. The system includes a Digital Controller mounted to the control panel, a Sensor mounted in a shield under the heater, a relay and an Infrared Heater. The digital controller is set to the desired temperature and the Sensor measures the temperature at the face of the heater. The sensor re- ports back to the control, and the relay sw itches the heat on and off to the heater. Startup Procedure Dryer Operation
