Overheat protection
SE06-15:
The over heating protection is intended to
restrict the exhaust temperature to 70 °C.
At 70 °C an output step is tripped off. If the
temperature continues to rise all output
is interrupted at 75 °C. If the temperature
continues to rise despite this, for example
because of a faulty contactor, the fan will
start to spin at 70 °C to keep the temperature
down. At the same time there is an over
heating alarm, see Table - Alarm. At internal
temperatures of +80 °C the fan runs at
maximum speed.
If the unit cools the output is engaged
again. The alarm remains in the control unit's
display. If the unit overheats twice within
an hour, the alarm must be reset before
the heating can be engaged again, the fan
operates until the alarm is reset.
SE20-30:
The over heating protection is intended to
restrict the exhaust temperature to 85 °C.
At 85 °C an output step is tripped off. If the
temperature continues to rise all output
is interrupted at 90 °C. If the temperature
continues to rise despite this, for example
because of a faulty contactor, the fan will
start to spin at 85 °C to keep the temperature
down. At the same time there is an over
heating alarm, see Table - Alarm. At internal
temperatures of 95 °C the fan runs at
maximum speed.
If the unit cools the output is engaged
again. The alarm remains in the control unit's
display. If the unit overheats twice within
an hour, the alarm must be reset before
the heating can be engaged again, the fan
operates until the alarm is reset.
Note! In event of repeated alarms and over
heating alarms, carry out a thorough check
and if the fault cause cannot be found contact
