Technical remarks
Gas Flow Interruption
On a gas-heated drier, the electronic ignition will only try to ignite five times in
a time span of 5 seconds. If this does not work, and the flame detector does not
detect a flame (e.g. in the event of a gas flow interruption), the ignition relay is
triggered. When the drying cycle is restarted , the reset button shall be pressed for
three seconds in order to generate a new ignition.
Electronic temperature
protection
When a temperature of
5°C or less, or of 120°C or more
has been detected, the
electronic temperature protection will be activated.
During operation :
Temperature higher than 120°C :
Every action is interrupted. “tMp” is blinking on the display.
Temperature lower than 5°C :
The heating is interrupted but the cycle will be completed. “tMP” is blinking on
the display at the end of the cycle.
During non-operation :
“tMP” is blinking on the display and the cycle can’t be started anymore.
Because of these protections, the dryer can’t be used at a temperature
of less than 5°C.
Underpressure switch
In case the drum no longer rotates due to failure (for instance breakdown of a V-
belt),
" rot "
will appear blinking on the display if the machine is equipped with
a rotation sensor (option) and the cycle continues without activating the heating.
The rotation sensor is fixed at the back of the dryer near the drum axle.
The underpressure switch is a protection which interrupts the heating, in
case there is insufficient air supply. This can be the result of an inadequate
exhaust (see installation), of a dirty filter (see maintenance).
In case of a malfunction, " VEn " appears blinking on the display and
the cycle continues without activating the heating.
Rotation sensor
If the machine is equipped
with a rotation sensor
, the bridge (A) on the
printboard needs to be
cut through
. If not, the same error message will
be shown on display.
