Safety Device

Section 5
(1) High and Low Temperature Limits
The high temperature limit of the top plate is set to 350°C to protect
you and your media. However, you can set your own high and low tem-
perature limits to reduce operation time and also to avoid inadvertent
mistakes.
(2) If the temperature of the top plate exceeds the set temperature range,
the heater will be automatically turned on and off and the Heater LED
will be turned on and off accordingly.
(3) Multiple Overheat Prevention Measures (ERROR 1 / ERROR 3)
Built-in overheat prevention circuit will turn off the heater if the plate
temperature reaches 450°Cfor any reason. In addition, if the temperature
of the main body exceeds 85°C the overheat prevention circuit also stops
heating to protect the motor and the PCB. You will be alerted by both
audible and visible signals will be activated.
(4) In such cases, turn off the power switch and disconnect the power cord
first. Then allow your unit to cool down completely before operating it
again.
(5) Hot Top Warning Indicator
The top plate temperature can remain very hot for some time even after
the heater is turned off. To prevent injury or fire under such circum-
stances, this equipment has a hot top warning indicator on the control
panel. This indicator will illuminate if the top plate temperature is over
50°C. Even so, do not rely on this indicator alone for your safety.
(6) Temperature Probe Warning (ERROR6,7)
On temperature control mode if the external probe is in the air or is not
enough socked into the media, error message will be shown on display
and heater will be automatically turned off.
(7) In such cases, turn off the power switch and disconnect the power cord
first. Then allow the temperature probe to completely sock into the
media(more than 20mm deep) and operate it again.
• If any overheat prevention activates or warning sound is alarming, turn off the
power switch and disconnects the power cord first. Then allow your unit to
cool down completely before operating it again.
