Setup (cont.)

4. Load Tapes into Sealer

Pull the cover tape down through the cover

tape guides as shown. Pull about 12” of cover

tape out and lay it over the carrier tape, with

the free end pointing toward the sealer. The

shiny side of the tape should be up. Allow

about 2” of the free end of the cover tape to

hang over the end of the carrier tape. Push

the tapes under the cover tape guide and

through the sealer by pushing on the carrier

tape. Keep enough slack in the cover tape so

it follows the carrier tape through the sealer.

Lift the idler wheel (Fig. 2.2, Ref. E) by push-

ing down on the left side of the arm. Align the

sprocket holes in the carrier tape over the pins

on the drive sprocket (Fig. 2.2, Ref. F).

Straighten the cover tape so it is aligned with

the carrier tape and rewind any remaining

slack back onto the cover tape reel. Position

the cover tape so it is running in the groove in

cover tape guide #3. Replace carrier tape

guide #2 and screw it down. Close the parts

cover.

5. Mount Take-up Reel

Mount an empty take-up reel on the take-up

reel spindle (Fig. 2.2, Ref. H). The width of the

reel must match the width of the carrier tape

and the reel must be big enough around to

accommodate the number of components in

the taping job.

All four factors may be varied on the TM-300

but only the dwell time, seal pressure, and

temperature setting changes are usually

required. The seal width is selected at the fac-

tory and should only require changing under

unusual circumstances. The settings in the

chart are good general starting points to be

used when first learning to use the TM-300.

Experience will suggest variations from these

settings that will provide the desired seal char-

acteristics as determined by a peel force test.

Setup (cont.)

General Seal Setting Information

The cover tape peel force is determined by

four things at the time the cover tape is sealed

to the carrier tape.

These four factors are:

1. The width of the sealing track on the

heat seal shoe.

2. The pressure applied to the seal area.

3. The dwell time, or heating time that the

heat shoe is pressing on the cover tape.

4. The temperature of the seal assembly.

Approximate Starting Points for Seal Controls

***Use this chart as a guide for setting the controls for the first time. These values may need to

be altered due to variations in lot materials and customer requirements.***

Setup (cont.)

Temperature Controls (cont.)

Increment Key (Ref. E)

When pressed, increases the set temperature

value. Successively increases the value when

held down.

Decrement Jey (Ref. F)

When pressed, decreases the set temperature

value. Successively decreases the value

when held down.

Return Key (Ref. G)

Each time pressed, changes the readout on

the main display as shown in Figure 2.15.

Present Data Indicator (Ref. H)

“SP” lights while the set temperature is dis-

played.

Setting the Temperature Controller

1. Press the Return key until the “SP” inicator

lights.

2. Adjust the value by pressing the ( )

or ( ) keys until the desired set temper-

ature is displayed.

3. Press the Return key again to display the

current temperature.

There is one temperature controller for the

inside heat shoe and one for the outside heat

shoe. Normally the two controllers should be

set with the same values, but they can be set

differently if the seal characteristics dictate

that the one controller needs to be set higher

than the other.

Error Messages

If there is a fault (short or open) in the temper-

ature sensor (thermocouple) of the sealer, the

display will flash “ “ or “ “. This

error message will also be displayed if there is

no sealer connected to the TM-300.

Temperature Controls (Figure 2.14)

Led Deviation Indicator (Ref. A)

The ( ) indicator lights when the current tem-

perature is higher than the set temperature.

The ( ) indicator lights when the current tem-

perature is lower than the set temperature.

The ( ) indicator lights up green when the

current temperature is within the steady state

range of the PID cycle.

Main Display (Ref. B)

Sequentially displays the present temperature,

set temperature, and an alarm value each

time the RETURN key (Ref. G) is pressed.

Control Output Indicator (Ref. C)

Lights while the control output is being pro-

duced.

Alarm Indicator (Ref. D)

If the present temperature exceeds or falls

below the set temperature, by the alarm value,

this indicator will light. This feature is not

implemented on the TM-300 Controller.
