Pad element
resistance outside of
nominal limits
. The
Pad resistance deviates
more than 20% from
the anticipated value.
This may occur when a
Heating Pad is
beginning to go
defective.
Low initial Pad
temperature
. The
Control Unit has
calculated the Heating
Pad temperature to a
value lower than 15°C.
Action
:
Reset the alarm. If the alarm re-occurs, the
Heating Pad should be analyzed and/or replaced
Action
:
If there is a logical explanation (a cold start
when the Pad is chilled), just reset the alarm and the
system will operate as usual. If the Heating Pad actually
is warm, or the alarm re-occurs, the Heating Pad or the
Control Unit should be analyzed and/or replaced.
Hot-spot warning
.
One or several of the
Pad elements has had a
calculated temperature
higher than the set
value, during 10
minutes.
Slow cooling
. The
average temperature of
the Pad has had a
calculated temperature
higher than the set
value, during 5
minutes.
Action
:
If there is a logical explanation (something
has accumulated the heat), just reset the alarm and
the system will operate as usual. If there is no
apparent unusual operating condition, or the alarm
re-occurs, the Heating Pad or the Control Unit should
be analyzed and/or replaced.
Action
:
If there is a logical explanation (a lowered
temperature setting with a heavy body on the Pad that
has accumulated excessive heat), just reset the alarm
and the system will operate as usual. If there is no
apparent unusual operating condition, or the alarm re-
occurs, the Heating Pad or the Control Unit should be
analyzed and/or replaced.
The Control Unit’s
log-file is very large
(time for service of the
unit).
Abnormal
temperature
variation detected
. A
change in the Pad
temperature faster than
5°C in 3 sec has been
detected.
Action
:
The alarm can be reset and the system will
operate as usual. Before the unit is used next time,
the Control Unit should be serviced by an authorized
technician.
Action
:
The alarm can be reset and the system will
operate as usual. If there is no apparent unusual
operating condition, or the alarm re-occurs, the Heating
Pad or the Control Unit should be analyzed and/or
replaced.
