Regulating the Cylinder Heat
Electrical Heating
To heat the cylinder with electric heat, the current is
modified through one or two groups of resistors
controlled by the heating switches.
Heating by one resistor group
When the finisher is set up to work with one resistor
group, a special control function for closing and
opening the heating relay switch around the set point is
activated. When activated, the cylinder is able to reach
and maintain the preset temperature and thermal
overshoot is avoided.
When heating is activated, the decimal point on the
temperature display lights up.
Heating by two resistor groups
When the finisher is set up to work with two resistor
groups, the temperature is regulated by the first group
as described above, while the second resistor group
operates continuously when the cylinder temperature
is less than the preset temperature. The second resistor
turns off when the preset temperature is reached.
When heating is activated, the decimal point on the
temperature display lights up. When only one resistor
group is activated, the decimal point will blink.
Gas Heating
To heat the cylinder with gas heat, the finisher is fitted
with a microprocessor that controls the ignition and
the gas heater when the temperature is lower than the
preset temperature. If necessary, the gas heater is reset
by turning finisher off or when pressure switch returns
to the normal position after correcting an insufficient
air flow condition. Refer to Alarms section for
additional information on insufficient air flow or if no
flame is present.
When heating is activated, the decimal point on the
temperature display lights up.
