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 conditions, but the dryer should always have the belt moving while the heaters are above 300 de-

grees. The belt should remain tracked in the center of each pulley. (See “Belt Installation and Tracking” for adjustment instructions.)

Aligner The aligner is a device for tracking the belt and keeping it on the 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 perfectly centered on the pulley but should not be hanging over either edge.

Pulley The pulleys at either end of the conveyor are made by VASTEX of 4 ½ inch steel tubing with ¾ inch center shaft. They are mounted on

self aligning flange bearing blocks for precision rolling.

Gear Motor A 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 #35chain.

Replacement part numbers can be found on your dryer’s wiring diagram.

IR Heater The infrared heaters in VASTEX dryers emit medium wave infrared heat, perfect for curing plastisol inks. The heater connections are

located in the trough on the right side of the heater, connected with high temperature terminals and stainless steel socket head cap

screws.

J Sensor Vastex uses a mineral insulated “Type J” Thermocouple mounted under the first heating element on the right side. It is shielded to pro-

vide a near “closed loop” control system. The sensor reacts very quickly to heater changes and is designed to be aware of changes in

the chamber’s environment. The sensor is wired to the Digital Temperature Controller found on the control panel.

Refer to wiring diagram when replacing “J” Sensor. (if SBER is displayed on controller, “J” Sensor is malfunctioning)

Control Box The Control Box contains most electrical components and is designed for easy maintenance. Connections should be checked after the

first (3) months of use and every (6) months after. More information on the Control Box can be found in the Controls sections.

Crank Handle Used to raise and lower IR Heater assembly. Turning the handle clockwise raises the elements, counterclockwise lowers them. Vastex

dryers use three variables to control the curing process, 1) Belt speed, 2) Temperature and 3) Heater height (Heater Focusing).

Exhaust Stack 8” exhaust stack. See Dryer & Exhaust Hood Ducting for proper venting.

(Note: Restricting the dryers exhaust can affect the operation of the dryer causing excessive heat buildup within the chamber

and fumes to fill the chamber and work area. The excessive heat buildup in the chamber may damage the dryers exhaust blow-

er. Proper venting is important.)

Filters the incoming air. Clean or replace this filter often and as needed, replacement filters p/n (06-22-040)

Heat Switch: Controls power to heater only.

Temperature Control: Set and control temperature here. See Page 14 for Controller information.

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. 1 light per relay is used.

Control Output Light: A 250 volt GREEN pilot light is wired to the output side of the temperature

controller. This light should cycle on & off with the controller. It verifies that

the controller output voltage is going to the relay coil.

Power Switch: Controls power to Controls. Shutting this switch off does not make it safe to

open the Control Box. Shut off power at main disconnect before servicing,

Power Light must be out before entering any part of this machine.

Belt Speed Control: An AC-DC converter is mounted to the face of the control panel which allows

the operator to vary the DC volts to the motor.

DC Volt Meter: Digital Volt Meter displays, in volts, the amount of power going to the belt

motor. This makes setting and adjusting belt speed much easier. A table

showing the time associated with voltage can be found in Dryer Operation.

Heater Light: This 6 volt WHITE pilot light is wired to the IR Heaters. One light per heater is

used. These lights indicate when electricity is flowing through each heater.

Power Lights: Wired to the non-fused load switch.1 for single phase, 2 for 3 phase. Will be

illuminated whenever the load switch is in the on position. At the end of the

day, the machine should be disconnected so the light(s) is/are out.

Components found inside control box.

Relays: ECONORED Dryers are equipped with SSR (Solid State Relays). The relays are the

switching devices which send the power to the heaters. The relay coil is wired to lug

#9 on the digital temperature controller. As the controller gets a signal from the sen-

sor, for heating or cooling, the relay opens and closes its solid state contactor to mod-

ulate power and maintain a consistent temperature. On 208V - 240V units, each relay

is wired to an output light which helps to monitor their operation.

Fuses: Two system fuses are found in the control box, and protect the internal electronics.

-Control box cover is “hooked” on the top and bottom

3) Pull the bottom of control box towards you slightly to unhook.

4) Lift up slightly, to unhook top of cover, and pull straight off.

Note: Cover cannot be removed with the disconnect in the ON position. The handle and shaft are keyed

to prevent this.

Installation is the reverse of Removal. Be sure to leave the disconnect in the OFF position for correct

alignment to the handle.

ONLY QUALIFIED TECHNICIANS SHOULD OPERATE/TEST CONTROL BOX COMPONENTS UNDER POWER

Main Power Switch:

Disconnects ALL power to the internal components

(Disconnect Switch) to allow safe access to the inside

of the control box. Power Lights are wired to the output

Curing Plastisol with infrared:

Plastisol ink can fully cure in approximately 20-30* seconds. The ink must achieve 310°-320°F (154°-160°C) to cure and fuse to

the garment. We recommend* a starting temperature 800°F (427°C), 3” heater height and a belt speed of 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 before

the ink can cure. We have seen cure times from 50 to 90* seconds to achieve a full cure or discharge and not damage the gar-

ment. Please note as the time is increased the temperature must be decreased to protect the garment from scorching.

*Actual cure times can vary depending on conditions such as garment moisture and 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 temperature than seen at the garment. Set the tem-

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 end of the dryer while it is still under the last heater. Take into consideration the thickness of 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 effect

the ink temp.

Operation Tips

 While machine is in operation, it is necessary to have the belt moving while the heater is above 300°F(149°C).

 Allow approximately 15 minutes for dryer to reach 700°F - 800°F (371° - 427°C).

 If no garments are being run through the dryer for more than 10 minutes, it is recommended to lower the heat set point

to 500°F (260°C). It will take approximately 10 minutes to return to operating temperature.

 Periodically check ink temperature at the exit of the dryer. It is recommended that you check the temperature of the ink

towards the outside of the printed image.

 When checking temperature with a laser gun, shoot the ink while it is still under the heater

Startup Procedure

Turn on Power Switch: Power is sent to the heater switch, belt speed controller, and the exhaust fan will start.

Turn on Conveyor: Set speed to desired setting.

Turn on Heat Switch: Turn on the Temperature Controllers.

Check belt path: Remove any objects from the conveyor and belt.

Control System Summary:

The control system in your dryer is called a “closed loop system”. 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 reports back to the

control, and the relay switches the heat on and off to the heater.

Rotate main power

switch to ON: The red Power Light will illuminate. Main Power Switch located on side of control box.

*** Shutdown Procedure ***

Turn off Power Switch: Turn the Power Switch to STOP only after dryer has cooled to 300°F (149°C) or lower.

Verify that the only Diagnostic light still on is the Power Light.

Turn off Conveyor: (optional) Once the dryer cools down to 300°F (149°C) or lower, turn the Belt Speed down

to the off position, skip this step if leaving the conveyor belt speed set for the following shift.

Turn off Heat Switch: Turn the Heat Switch off. Allow the heaters to drop to a maximum of 300°F (149°C) before

turning off the conveyor.

Always follow dryer shutdown procedure at the end of all shifts and / or production runs.

The Dryer Shutdown Procedure is also defined on a label affixed to the front of the dryer.

The dryer must be shut off via the Main Power Switch at the end of every shift.

At this point, no lights should be illuminated on the Control Box.

Rotate main power

switch to OFF:

Set the Belt Speed: Rotate the Belt Speed Control Knob clockwise to increase speed and counter-clockwise to

decrease it. Refer to the example chart below for Time Through Chamber settings. For Plas-

tisol 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, the (SV) will climb. The longer you hold the but-

ton, the faster the (SV) will climb, it will start climbing by one, then ten, then hundreds. Set the

desired temperature and allow approximately 15 minutes for heat up.

-Refer to the Troubleshooting section for Controller Error Messages.

Set the Heater Height: Rotate the Hand Crank on top of the Dryer Chamber, clockwise to raise the heaters, and

counter-clockwise to lower them. Set the desired heater height for your job. It is recommended

to run the heater height at about 2” - 3” above the garment.

Time through chamber

As explained on the Controls page, your Vastex dryer displays Voltage sent to the motor in reference to Conveyor

speed. Below you will find an example chart relating Voltage to Time Through Chamber. Time Through Chamber is the

time it takes an object to travel from the beginning to the end of the Heat Chamber. This is also known as “Time in Heat”.

Temperature Controller

Auto Tuning Automatic Tuning has been performed at factory for all machines. Automatic Tuning must be performed by the customer for the

following reasons; When equipment is other than 240v (e.g. 208v), replacing a controller, replacing a sensor, and/or new heating

elements. Controller set point value must be set to 500°F (260°C) for 120V units, for all other units set to 700°F (372°C). Set point value

must be entered before going to the auto tuning selection screen. Auto tuning should only be performed when the heater temperature is

below 300° F (150° C).

damages that occur during shipment that do not affect the functionality of the equipment.

(2.) This warranty is expressly contingent upon the buyer delivering to seller, at the address below, with all transportation charges prepaid, the part or parts claimed to be

defective within the above mentioned warranty periods stated in paragraph one. The defective part or parts will be repaired or replaced at the discretion of Vastex International,

Inc. If the equipment in question is less than one (1) year old, it will be shipped to the customer at no charge, with an RGA issued by Vastex for the defective part. The defective

testing and analysis of said part by the seller or its supplier discloses that said part is defective, the cost of said part will be refunded to the buyer on a prorated basis.

(3.) Except as otherwise provided herein, the equipment is being sold “as-is”. Final determination of the suitability of the equipment for the use contemplated by the buyer, is the sole
