Description of the device
The Shannon HR line heater is a device for the production of items for the
plastic sheet processing industry.
The device has one adjustable heating element as standard. The temperature
of which can be adjusted by an electronic control.
The filament of the heating element on the working surface is adjustable in
height.
The piece of work can be heated from one side and it is possible to bend
sheet up to 5 mm thickness.
The working surface is made of scratch-resistant solid core material, to
support the plastic sheet.
When heated, thermoplastics become so flexible that they can
be shaped. When a plastic sheet is heated to its softening point
in a narrow zone, if can be bent to any angle desired.
The bending radius is determined by the width of the heated
zone. The zone is determined by the thickness of the material,
the type of heating element and the distance between the plastic and the
filament.
Every plastic has its specific softening point. By co-ordinating the temperature,
heated zone and heating time all kinds of thermoplastic can be processed.

Safety instructions
SAFETY INSTRUCTIONS:
To ensure safety when using the device you should read this User's Guide
carefully and follow the safety instructions closely.
Attention!
The device contains parts which are hot. Touching them will cause burns.
Allow hot parts to cool sufficiently (at least 10 minutes) before touching them.
Never touch the filament or the reflector when the device is in operation.
Always wear close-fitting clothing.
Be particularly careful of sleeves and always tie back long hair.
Never leave objects on the working surface.
The device may only be used for heating narrow zones in flat plastic sheet.
Any other use could lead to very hazardous situations or cause damage to the
device!
Before commissioning and servicing always check the connection cable and
plug for defects.
When servicing switch off the device and remove the plug from the socket.
Never leave the device unattended without switching it off.

Operation
6.1 PREPARATION
1. Clear the working surface (W).
2. Check that the heating element is connected to the control unit.
3. Check that no scraps of material remain in the reflector.
4. Turn the potentiometer (M) in the control units to "0".
6.2 SWITCHING ON HEATING ELEMENT

Operation 6
6.3 SETTING TEMPERATURE
The temperature of the filament can be set using the temperature control.
1. When turning on the on/off switch, the display will show the value that was
last saved (keeping the machine on a certain value for >20 seconds will
make it remember this value).
2. Press the right button (arrow up) to increase the value, up to 99 (keeping
this pressed in will make the value cycle much faster)
3. Press the left button (arrow down) to decrease the value, down to 00
(keeping this pressed in will make the value cycle much faster)
4. Press both buttons at the same time to go directly to 00. Doing this also
resets the machine.
6.4 TROUBLE SHOOTING
This machine does not cause for a lot of problems.
The display will give an error message if something is wrong.
Error message

Solution
E1
The wire is loose (not connected)
Turn off the machine, check the filament, and reset the
machine
(see §9.1 for changing filament)
Note: Between the values 00 and 04, this fault cannot be
detected
E2
The wire is loose (spark detection)
Check the connection of the filament
Check the filament, and reset the machine
This fault can also be reset by the arrow down button
(see §9.1 for changing filament)
E9
Broken circuit board
Contact the supplier for a new circuit board
Empty display
No power
Alert a maintenance engineer
Check the fuse (see §10.1)
Check the power supply cable
Contact the supplier if necessary
