1.0 Introduction

The heat sealers described here are purpose designed for safe disposal of used filters in a wide range of

applications and industries. They are semi-automatic in operation and no special operator skills are re-

quired. However, some adjustment is required to obtain the best results from the equipment, which is

described later in this document.

Heat sealing of polythene tubing and similar materials is achieved by simultaneous application of heat

and pressure and these machines operate on the “impulse” principal, which means that the seal bar is not

continuously heated. On initiation of the sealing cycle, by momentarily pressing the green push-button,

the electronic timer circuit passes a high current through the heating element for a brief period, typically

of a few seconds in duration. The Red LED (adjacent to the push-button) indicates that the Heat + Cool

cycle is in operation. As soon as this LED extinguishes, the weld is complete , the toggle clamps can be re-

leased to remove the top bar and the welded material removed.

2.0 Seal Control Module

The SCM200 Seal Control Module, fitted in the Control Box, provides a simple system for setting the

machine to seal any particular material and to accurately repeat those settings when subsequently

required - by simply recording the numbers on the four thumb-wheel switches.

Seal Time setting = 00 > 99 representing 0 > 10 seconds (example ‘3 4’ setting = approx. 3.4 seconds)

Trim setting = 0 > 9 ….. Where 9 represents minimum compensation (factory set at ‘9’) …. See below

Cool Time setting = 0 > 9 representing 0 > 20 seconds (example ‘4’ setting = approx. 8 seconds)

Note: The above timings are only approximate but what is important is there repeatability.

Note: Always record the four numbers for future use (i.e. 3 4 9 4 in this example)

Trim Setting

This adjusts a simulated rate of cooling of the heated bar after the Seal Time has elapsed in order to

automatically foreshorten the second and subsequent Seal Times to compensate for heat remaining in the

tool. Assuming there will be some considerable time between Seals, this is factory set at ‘9’ for effectively

no compensation (no heat retained). If adjustment is required, we recommend reducing one number at a

time and doing two or three test seals at the required interval.



3.0 Operation

The machine consists of a Control Box and separate Sealing Head

CONTROL BOX

Power Transformer to provide high current at low voltage to the heating circuit

Protection Fuse accessed from the rear of the unit, to protect the Transformer primary winding.

SCM200 Seal Control Module to set repeatable ‘Seal’, ‘Trim’ and ‘Cool’ times

Power relay to switch the high current supply to the Heater Bar

7-pin power socket to connect control circuits and high current supply, to the Sealing Head.

Please order for 115V or 230V operation

As standard, 230V units include an integral 1.4 metre mains lead with moulded UK 13A Plug.

As standard, 115V units include an integral 1.4 metre mains lead with un-fused 32A IP44 Industrial Plug.

SEALING HEAD

Base assembly with Heating Bar, Green Push-Button, Red ‘Seal Cycle’ LED, 2.6 metre cable with 7-pin plug

Top Bar with handles and silicon rubber Pressure Pad.

3.1 Preparation of Machine

Plug the Sealing Head 7-Pin connector into the mating half on the Control Box and remove the Top Bar

and place this in a clean and safe place. Do not plug into the mains supply at this time. Note: It is impor-

tant that the machine is NOT stored with the Top Bar clamped, as this will damage the Silicon Rubber

pressure pad.

3.2 Preparation of Filter Bag for Sealing

• Isolate from the Mains Supply

• Lay the Filter Bag across the Bottom (Sealing) Bar ensuring that the bag lies flat and is free from

creases and folds

• Replace the Top Bar, and secure using both Toggle Clamps. The Bag is now ready for Sealing.

3.3 Sealing Operation

• Connect the Control Box to a mains supply and the RED ‘Power’ LED should light in the display window

• Press the Green Push-Button on the Sealing Head and the adjacent Red Led should light, indicating

that the Sealing Cycle is in progress (additional LEDs in the window on the Control Box will also

indicate the separate Seal and Cool times within the Seal Cycle. When the RED LED on the Seal Head

extinguishes, the Seal cycle has finished. Switch off the mains supple, release the toggle clamps,

remove the Top Bar and Filter Sack

• It is strongly recommended that prior to doing a safe change, the operator does a sample seal to

ensure that the seal is satisfactory for that material. Remember to record the Thumbwheel switch

positions for future use.



4.0 Safety

The machine contains parts that are electrically ‘Live’, even when the SCM200 Controller is in standby.

The electrical supply MUST be disconnected prior to removal of the control box cover. A competent Electrician must

carry out any repair or test work, or alternatively the machine should be returned to the supplier.

The machine is fitted with a mains supply fuse, accessible at the rear of the Control Box, to protect the transformer

primary winding. The machine is also fitted with a mains lead and moulded 13A Mains plug on the 230VAC version

and with an unfused 32A IP44 Industrial Plug on the 110VAC version. The machine must be earthed at all times.

The machine incorporates several features to help ensure operator safety -

a) The source of the heating current, is isolated from the mains supply and is at a safe low voltage.

b) For the machine to operate, the Sealing Head must be plugged into the Control Box

c) The top bar must be fitted and secured by the toggle clamps.

d) Press the green push-button for approx. 1 sec and the adjacent Red LED will light to indicate that the Seal Cycle is

in operation

e) Red LED extinguishes to indicate Seal Cycle complete and Top Bar and material can be removed

WARNING: - Immediately after the seal cycle has completed, the bars will be hot. The operator should avoid finger

contact with heated surfaces and in particular when removing the top bar and sealed material. Ensure that the top

bar is placed safely such that it cannot be damaged and cannot damage anything else.

WARNING: - When choosing a working position, it should be noted that the machine as a whole is not sealed against

the ingress of water or dust. However, a dust proof door assembly is fitted to the Seal Controller to protect the

Thumb-Wheel switches.

5.0 Maintenance

5.1 Mechanical

The design and construction of the machine makes regular mechanical lubrication and maintenance unnecessary.

Keep the Teflon fabric cover over the heating element clean and free of contamination

Keep the silicon rubber Pressure Pad free from contamination, and NEVER store the sealer clamped

5.2 Cover Tape and Heating Element

The seal bars, both heated and unheated, will require attention at intervals, dependant on factors such as workload,

material thickness and temperature.

Bars in good condition will produce seals of constant width throughout the entire length and will exhibit a clear

impression of the texture of the Teflon cover tape. If the seal quality is unsatisfactory, then check the bar condition

as follows, ensuring that only manufacturer’s approved materials are used.

Examine the Silicon Rubber and replace if required

Examine the Teflon cover tape for cracks, surface defects or burn marks. Please contact the supplier or

Manufacture for guidance as the Teflon cover tape cannot be replaced without dismantling the Sealing Head.
