Setting An Over Temperature Cut-Out Value
If, for example, you would like to operate your incubator at +20.0°C, an over
temperature cut-out value needs to be programmed into the cut-out. We recommend
that the cut-out value is set to
2 degrees higher
than your chamber temperature. In
the example above, the over temperature cut-out set point needs to be set +22°C. To
do this follow steps 1 - 3 below:
a) Press the
P
button
once only
. Flashing
AL1
will be displayed plus a value
(the
over temperature
cut out value).
b) Press the
▲
button to increase the
over temperature
cut-out value or the
▼
button to decrease the
over temperature
cut-out value.
c) Once the value of your choice is displayed, press the
P
button again and the
new value will be stored and retained in permanent memory.

Over Temp Neon, Buzzer & Reset Button
If your incubator overheats, the buzzer will sound and the over temperature neon will
illuminate.
The heaters will automatically disconnect to prevent further
overheating
. Once the chamber temperature has stopped rising, and has fallen
below the cut out set point, the heaters will re-connect automatically. The buzzer &
neon will remain on until a member of staff has acknowledged the alarm. To reset the
buzzer & alarm, press the reset button alongside the illuminated neon.
3.6
Setting An Under Temperature Cut Out Value
If, for example, you would like to operate your incubator at +20.0°C, an under
temperature cut out value needs to be programmed into the cut out. We recommend
that the cut-out value is set to
2 degrees lower
than your chamber temperature. In
the example above, the under temperature cut out set point needs to be set +18°C.
To do this follow steps 1 - 3 below:
a)
Press the
P
button
twice
. Flashing
AL2
will be displayed plus a value (the
under temperature
cut out value).
b)
Press the
▲
button to increase the
under temperature
cut out value or
the
▼
button to decrease the
under temperature
cut out value.
c)
Once the value of your choice is displayed, press the
P
button again and
the new value will be stored and retained in permanent memory.

Under Temp Neon, Buzzer & Reset Button

. The buzzer & neon will remain on until a member of staff has
acknowledged the alarm. To reset the buzzer & alarm, press the reset button
alongside the illuminated neon.
