High Limit
The controller is equipped with an integrated high limit control. Should the operating
temperature rise above the high limit set point, the dryer will shut down automatically.
To change the high limit temperature set point:
1) From the Home Page press the ADVANCE (green) key 6 times. “250” (factory default)
should appear in the upper display and “sp.5
i
” in the lower display.
2) Use the UP or DOWN key to adjust the high limit set point.
3) Hold the RESET key until you return to the Home Page.
If under normal operation, the high limit set point is reached the dryer will shut down, and
prevent the dryer from being restarted until the dryer has had sufficient time to cool down.
Reset the panel power after the dryer has had time to cool to clear high limit error. Error
message: “l
i
.h1” in the upper display and “attn” in the lower display.
The integrated system has its own sensor that monitors the temperature inside the plenum,
separate from the sensor that controls the actual temperature. However these sensors are
located in the same junction box. Should the high limit sensor fail, it will automatically shut
control circuit power to the dryer and prevent it from being started until the problem with the
high limit sensor is fixed. Error messages: “l
i
.e1” ; “er.
i
2” in the upper display and “attn” in the
lower display.
If the temperature control sensor fails, the system is designed to flash a warning message that
indicates that there is a sensor error. The dryer will still operate under this condition, but it is
advised the temperature control sensor be fixed. Error message: “er.
i
1” in the upper display
and “attn” in the lower display
