NB.Always use good screwdrivers when changing electrical connections. Bad screwdrivers ruin screw heads and all connections need to be tight to prevent a “hot connection” which will burn the wires.

Heating
Elements. Most 700 and 8000 Texitunnels are fitted with curved Vulcan
V1 elements. Older dryers and flash dryers are fitted with square
Vulcan V3 elements. Those with a temperature sensor mounted in them are
type KTC. These can be obtained from Vulcan Refractories Ltd. Tel.
01538 752238.
NB. When fitting elements with a temperature sensor
remember that the sensor lead with the red spot on it is POSITIVE and must
connect to the red or green line in the sensor cable. Heating elements
can also be obtained from – Ceramix in Ireland, Hawco Tel. 01483 869001
and RS Components in England and KG Steinmetz -Elstein in Germany.
Conveyor Belts These can be obtained from Techbelt. Tel. 01422376212
The normal belt type is E25/2/2-Film-A36 and a normal 700 Texitunnel would
be 700x4050 The belt size is normally written on the inside of the
control box cover. Otherwise the length is 2x the distance between the
roller centres plus the circumference of one roller and the width is 6 or
7mm less than the internal length of the roller. NB. Never make a
conveyor belt too tight. It should only be tight enough to drive without
slipping.
Power Relays. If the temperature in the dryer goes up
to maximum when the controller is off – the relay has failed in the ON
position.

from Hawco. Part Nr HF105F-4 /230A-1HT. Tel: 01483 869001
Some
large dryers and some 1-phase 240V Mini Dryers are fitted with normal 3
phase contactors although on Minis not all of the connections are used.
These are available from any electrical wholesaler, RS, Farnell and Hawco.
Temperature Controllers Many different controllers have been used
but digital replacements for all of them are available from Tecnologic UK.
Tel 01250 377600 They can be pre-programmed ready for use. NB. When
replacing controllers with different types the wires often connect to
different terminal numbers.
Changing from the Hawco/Cal 8000
analogue controller to the Tecnologic K49T-HEOR digital controller.
You have to take the wires off from the removable CAL base and connect
them directly onto the base of the Tecnologic controller. I suggest that
you do it 1 wire at a time. Slide the wires through the controller
retaining clip and the front panel before attaching any cables to the new
controller. The numbers on the K49T controller base are very small take
care to identify them correctly in good light.
Cal 8000 K49T
Terminal 1 “Live + 240V AC input” to the controller goes onto TLK49
Terminal 7. Terminal 2 “Neutral –240V AC input” to the controller goes
ontoTLK49 Terminal 8. Terminal 4 “ blue or white Sensor negative –“goes
onto TLK49 Terminal 2. Terminal 5 “brown or green Sensor positive +”
goes onto TLK49 Terminal 1. Terminal 9 “DC to the SSR Neutral” goes
onto TLK49 Terminal 12. Terminal 10 “DC to the SSR Positive” goes onto
TLK49 Terminal 11.
When you switch the dryer on the controller will
always display TEST as it does a circuit check before operating.
Using the TLK 49 Dual Display Digital Temperature controller The top
line of the display shows the actual temperature of the heating elements
in Red and the lower line shows the set temperature in
Green. The red
light to the right of the actual temperature display is the power output
indicator. This is illuminated when there is power actually going to the
heating elements. The red light to the right of the set temperature
display illuminates when the alarm condition is on. This is not programmed
in a Cal replacement. To select the temperature press P and then either
the up or down arrow. The change is slow at first becoming faster. When
the desired temperature is indicated press P again to set the temperature.
K49T Temperaturregler mit Doppeldigitalanze. Die obere
rote Digitalanzeige zeigt die aktuelle Temperatur der Heiz-elemente, die untere
grüne Digitalanzeige zeigt die gewünschte, einge- stellte Temperatur
an. Die rote Lampe rechts von der aktuellen Digitalanzeige zeigt an ob
die Heiz- elemente an- oder abgeschaltet sind. Es leuchtet wenn Strom
zu den Heiz- elementen fliesst. Die rote Lampe rechts von der unteren
Digitalanzeige leuchtet wenn der Alarm eingeschaltet ist. Zur Auswahl
einer Temperatur, drücke zuerst P und dann die Pfeiltaste, Pfeil
hinauf
oder Pfeil hinab, bis die gewünschte Temperatur in der unteren grünen
Digitaelanzeig angezeigt wird. Zur Bestätigung dieser neuen ausgewählten
Temperatur drücke erneut P.
