9.4.23 51 Power Rating 3
Possibilities to independently the other outputs give the
power rating for output 3.
Option:
0-99.9 kW where 0.0 is inactive.
9.4.24 52 Pyro Regulator P (Propotional)
This option, together with 9.4.25, is used to fine tune the
heating system depending on the pyrometer readings.
9.4.25 53 Pyro Regulator I (Integral)
This option, together with 9.4.24, is used to fine tune the
heating system depending on the pyrometer readings.
By tuning the two parameters P and I in the PID control-
ler algorithm, the controller can provide control action
designed for specific process requirements. The re-
sponse of the controller can be described in terms of the
responsiveness of the controller to an error, the degree
to which the controller overshoots the set point, and the
degree of system oscillation.
To alter the values for P and I full understanding of PID
controllers is needed.
If this knowledge is not at site, please contact Hedson
Technologies AB if this needs to be adjusted.
9.4.26 54 Output 2 Scale
Possibility to control the level of power on output 2 from
0-100% compared to output 1. Default is 100%
9.4.27 55 Output 3 Scale
Possibility to control the level of power on output 3 from
0-100% compared to output 1. Default is 100%
9.4.28 56 Proc. Alarm Temp.
Possibility to set maximum temperature difference be-
tween current and requested temperature (5-99ºC). This
function is activated in 9.4.3.
9.4.29 57 Continuous Mode
Possibility to decide if the IRT dryer should have continu-
ous drying or time dependent drying. Yes = Continu-
ous drying. No = Machine stops when time countdown
reaches 0.
10. Maintenance and Service
Maintenance work is to be carried out at the stipulated
maintenance intervals by suitably trained personnel.
Do not use running water or flammable liquids for clean-
ing.
Abide by the following points to ensure a long service
life and continuous operation of the dryer:
•
Only original spare parts and suitable tools are to be
used.
•
Adhere to the maintenance intervals.
•
Contact your dealer or the manufacturer’s customer
service department regarding any maintenance
work that is not listed or shown in this manual.
Only undertake maintenance work when the maximum
lift (unloaded) is reached, the platform table has been
reinforced by service supports (part no. 195682) or
secured by a forklift at the top position and the com-
pressed air supply and electricity has been shut off.
10.1 Maintenance
Weekly
Check that all IR lamps light up during dryer operation.
Defect IR lamps can cause uneven heat distribution over
the surface.
Clean the dryer from dust, which can be a cause of fire,
with a damp cloth.
Check that all cables are undamaged. A damaged cable
can be a danger to life!
Monthly
Check the gold coated reflectors. Damaged or extremely
dirty reflectors can overheat the reflector body and/
or the cassette. In case of doubt, please contact the
customer service in order to clarify if the gold coated
reflector needs to be changed.
Check all moving parts such as pivot bolts, sliding pieces
and sliding surfaces for wear and tear; clean and lubri-
cate. Only use greases in the lacquer coated sections
that do not contain substances that might damage the
lacquer coating.
Check air bellows and air hoses for damage. Inspect
visually and check for leaks. Check the surface of the air
bellows for contamination; clean and maintain. Always
use appropriate care and cleaning products when carry-
ing out maintenance on the rubber surfaces.
Check that the valves are working correctly and check for
leaks.
Inspect the service unit provided by the customer (filter
regulator) and abide by the instructions in the manufac-
turer’s manual.
