No display on the timer The machine has not been used for a long time; Connect the machine to the mains and
thus the auxiliary battery has discharged
No temperature display Switch of the machine set to 0 (OFF)
on the digital
The power supply has been interrupted
temperature controllers Defective temperature controller
Defective visible type fuse
The heating plate does
Defective temperature controller
not heat up (enough)
The overheating cutout has switched
the system off
The alarm sign F1H/F1L or L is displayed
Defective timer
The temperature controller has been set
to an insufficient desired value
Defective heating mat
Damaged connection cable to the heating mat
Switch of the machine set to 0 (OFF)
Curing time has not been set.
The START button beside the timer
has not been pressed
The overheating cutout has been triggered off
The FI fault current breaker has switched
the system off.
Defective connection to the mains
Splits on the
Wear
heating pocket
Damaged heating mat
Wear
The operating pressure
The operating pressure of the compressed air
of 4-8 bar (60-115 PSI)
servo is too low
is not reached
Compressed air servo cut off/damaged
Note: In all these cases, after having solved the problem in question, you may have to repeat the curing operation or the
repair. For this purpose, check again whether repairing the tyre is economically reasonable and technically possible.
Alarm function 1:
If the sign F1H blinks on the red LED display, the thermo-
couple wire is broken in the heating mat or in the heating
mat connection cable.
In this case, the heating mat which is linked to the tempera-
ture controller is cut off automatically for safety reasons.
Important note:
The alarm indicates a defect in the electric system; check
the following parts:
a) heating mat cable:
defective or destroyed, because of
- loose or not secured plug connections to the
control box?
- squashing, broken thermocouple wire?
- cable pulled out of the heating mat connector?
b) heating mat
defect due to:
- a broken thermocouple wire, scorched spots?
- wear?
c) electronic temperature controller:
trouble due to
- loose internal cable connections?
- external effects such as impacts etc.?
Solution
check the timer after approx. one hour
Set the switch of the machine to "I" (ON)
Restore the power supply
Replace the temperature controller
Replace the visible type fuse
Replace the temperature controller
Check the heating mat together with its
cable; replace them, if necessary
(See VIII. page 38)
Pull the mains plug,
plug it in again after 3 - 5 seconds.
Replace the timer
Set it to 175
O
C/350
Replace the heating mat (See VIII. page 38)
Replace the heating mat (See VIII. page 38)
Set the switch of the machine to I (ON)
Set curing time
Press the START button.
- Check the heating mat together with
its cable; replace them, if necessary
- Disconnect the vulcanizing machine from the
mains, then put it into operation again
Operate the switch lever on the FI fault current
breaker
Have the connection checked by a
qualified electrician
Replace the heating pocket
Replace the heating mat. Periodically powder it
with talcum
Increase the operating pressure of the
compressed air supply
Check the compressed air servo
Alarm function 2:
If the symbols F1L or L blink on the red LED display, the
thermocouple in the heating mat or in the temperature con-
troller is not connected to the right poles.
Important note:
This kind of alarm indicates a defect in the electric system.
Disconnect the machine from the mains and have the trou-
ble shooting carried out by a TIP TOP technician.
After the defect has been eliminated, the controller is oper-
ational again. The alarm sign goes out and the actual value
is displayed.
If the alarm is triggered off again, disconnect the machine
from the mains and have the trouble shooting carried out by
a TIP TOP technician.
Important note:
The customer is not allowed to change the factory settings
as this may be dangerous and change the functions of the
system.
