Temperature Control
The TEMPERATURE control (Figure 5-8) is
used to set the temperature of the ironing cylinder
and to turn the gas system ON and OFF. See also
the information on the temperature sensor contact
shoes below.
Temperature Sensor Contact Shoes
The unit is equipped with two temperature
sensing devices which monitor the temperature of
the heated ironing cylinder. A oil-loaded capillary
tube and bulb is used as the sensing device.
Each sensor is housed in a spring-loaded
contact shoe which rides on the surface of the
heated ironing cylinder under the feed ribbons
(Figure 5-9):
• The one at the center (A) transfers
heat from the cylinder to the
TEMPERATURE control.
• The one toward the left end of the
cylinder (B) transfers heat to the high
temperature limit control.
If either of these contact shoes wear down,
breaks o, or is incorrectly placed against the
cylinder, inaccurate information will be read
by the TEMPERATURE control and/or high
temperature limit control, and the unit will not
function properly.
