OUTLET SENSOR BURNOUT
Abnormal temperature inside
multi-dryer
The ambient temp is high, the hot air leaking
from the outlet flows back into the operation
panel, and the effect of heat dissipation from
the furnace body due to the installation on
the top of the furnace body, etc.
Overheat prevention sensor
minus display
(For heater case temp sensing)
When the inside of the heater becomes
abnormally high temperature, the abnormal
lamp (red) lights up, "ALM" flashes in the hot
air temperature section, and "Tcb" flashes in
the set temperature section.
When the heater case becomes abnormally
high temperature, the abnormal lamp (red)
lights up, "ALM" flashes in the hot air
temperature section, and "TPb" flashes in the
set temperature section.
When the discharge temperature
exceeds the upper limit, the abnormal
lamp (red) lights up, "ALM" flashes in
the hot air temperature section, and
"TcA" flashes in the set temperature
section.

《MAIN CAUSES》
Insufficient air volume due to clogging of
the suction port filter, excessive
resistance on the discharge side, etc.
Air volume supply stopped due to
clogging of the intake filter, excessive
resistance on the discharge side, lock of
the blower, etc.

５．Each abnormality indication
When the multi-dryer is abnormal, the details of each abnormality are displayed and the operation is stopped (only the
internal temperature abnormality is in the ventilation operation state). Be sure to remove the abnormality and then
restart the operation by turning on the power switch again. (Depending on the abnormality, it may be possible to
recover with the stop switch. Also, only the overheat for detecting the temperature of the heater case will be manually
restored.) ..
Clogged suction port filter, insufficient air
volume due to excessive resistance on the
discharge side, or exceeding the upper limit of
the discharge port temperature when using an
external sensor
OVERHEAT PREVENTION
SENSOR BURNOUT
When the internal temp of the multi-
dryer rises above + 65℃, the abnormal
lamp (red) flashes, "oH" flashes in the
hot air temp section, and "ALM" flashes
in the set temp section.
If the outlet sensor is disconnected, the
abnormal lamp (red) flashes, "----"
flashes in the hot air temp section, and
"TcA" flashes in the set temp section.
If the overheat prevention sensor is
disconnected, the abnormal lamp (red)
flashes, "----" flashes in the hot air
temp section, and "Tcb" flashes in the
set temp section.
When the overheat prevention sensor
temp drops below -15℃, the abnormal
lamp (red) flashes, "----" flashes in the
hot air temp section, and "Tcb" flashes
in the set temp section.

When the outlet sensor temp drops
below -15℃, the abnormal lamp (red)
flashes, "----" flashes in the hot air
temp section, and "TcA" flashes in the
set temp section.
If the internal temp sensor of the multi-dryer
is disconnected, the abnormal lamp (red)
flashes, "----" flashes in the hot air temp
section, and "TcM" flashes in the set temp
section.
Please turn off the power and
request repair.
