8. Warning detection
8-1 Overheat
Overheat is detected in the case that the inside of the heater case became an abnormal high temp. Or,
burnout is detected in the case that the overheat sensor for the temp. control inside the heater case snapped.
And, the breaker (NFB) of this machine does trip and all the operation stop. (TSK-18 and Air volume
insufficient overheat prevention are only stopped the operation.)
●
At the time of overheat
●
At the time of overheat sensor burnout
●
At the time of air volume insufficient overheat prevention (Only TSK-52HT, TSK-62 - 132)
Please do not operate again until the cause is removed when the overheat is operated.
◆
Buzzer sounds at the same time as the warning detection about TSK-52HT, 62 - 132. Even
buzzer sound stops when warning was canceled by the return method of each warning.
Overheat lamp (Red) are lighted, and "nFb" is
flickered to HOT-AIR TEMP, "Tcb" to SETTING
《
Main cause
・
Clogging of the inlet wire net and filter
・
Lock of the blower motor by the mixing of the
foreign substance
・
Exhaust outlet of furnace etc. is not secured
sufficiently
・
Resistance (pressure loss) of the outlet is big by
the adjacency of object work
《
Return method
Please remove the cause of overheat. And ,
source power supply and the breaker of this
machine are turned OFF at first and are turned
ON again after cooling sufficiently. (TSK-18 is
only input of the factory power supply.)
Overheat lamp (Red) are flickered, and "---" is
flickered to HOT-AIR TEMP.. "Tcb" to SETTING
《
Main cause
・
Snapping of a wire of the overheat sensor
・
Snapping of a wire of overheat sensor wiring
・
Miss of the overheat sensor wiring connector
《
Return method
Please turn OFF the first power supply and
please order the repair.
Overheat lamp (Red) are lighted, and "oVH" is
flickered to HOT-AIR TEMP., "Tcb" to SETTING
This operates when air volume decreased by some causes and the
heater inside temp. is exceeded the setting hot-air temp. There is the
exchangeability to the above overheat. But, which operates by use
situation.
《
Main cause
・
The same cause as the above overheat
《
Return method
Please remove the cause of overheat. And ,
