Appendix 2 - Troubleshooting
Incubator Fault Codes:
Error 100: Temperature
The temperature of the incubator is outside the
acceptable limit for reliable operation. Ensure the
incubator is not located in extremely hot or cold
conditions. Either ‘Accept’ the fault to continue
with the incubation cycle or select ‘Back’ to cease
the current cycle and restart when the conditions
are appropriate.
Error 102: Low Temp
The incubator has failed to reach the temperature
set-point in the time permitted. Ensure the
conditions are suitable for incubation (no strongly
cooling conditions are present) and either ‘Accept’
to continue or ‘Back’ to cease, relocate and restart.
Error 103: Over Temp
Temperature is too high for effective resuscitation
or Peltier cooler is not reducing temperature
sufficiently. Remove from direct sunlight if
required and check air vent for blockages.
Error 107: Validation
A significant difference in measured response has
occurred between the two temperature monitoring
thermistors. The laser-trimmed thermistors are
factory calibrated and designed for long-term field
use. Any failure in the validation process indicates
a hardware issue and the incubator should be
returned to your local representative for attention.
Select ‘Back’ to accept the condition and continue
operation until service can be arranged.
Error 110: Battery Low
The incubator will determine the power required
at the start of an incubation and compare to
currently available capacity. If the capacity is less
than the power required the warning will
be displayed. Select ‘Accept’ to continue with
the incubation cycle but find an additional
power source to avoid losing power during
microbiological analysis. Select ‘Back’ to change
power source prior to starting incubation.
Error 111: Battery Critical
Battery has 10 minutes life remaining. Find a
replacement power source immediately. Select
‘Back’ to stop incubation until more reliable supply
is available. The message will remind at 1 minute
intervals until a new power supply is attached.
Error 112: Power Loss
The message will be shown on start-up of the
incubator if an unexpected loss of power occurred
during an incubation cycle. Select ‘Accept’ if the
root cause has been determined.
Error 114: Overheat
Incubator is above acceptable temperature for safe
operation. Select ‘Back’ and check air vents for
obstructions or remove from any source of indirect
or direct heat. Select ‘Accept’ if the condition is
temporary and the incubator will be moved to a
more acceptable location immediately.
Error 115: Critical Overheat
The message will be shown on start-up of the
incubator if an automatic shut-down occurred due
to a temperature being measured with potential to
damage the incubator electronics. Check for causes
such as blockages in air vents or direct/indirect
heat and ensure condition does not remain.
Error 116: Thermistor Failure
The two independent temperature measurement
thermistors will measure similar values in normal
circumstances. If severe mechanical damage has
occurred, the difference between the thermistor
responses
will be outside of specification and
temperature
display may be erratic/unexpected.
Return the unit to your local representative
for attention.
Incubator Use and Service
Should any condition arise requiring maintenance
or service, please contact your local Palintest
representative or via support@palintest.com
The Potalab
®
+ incubator is designed to provide
field or static incubation of microbiological cultures
at 20 - 50°C. Alternative uses will potentially
expose the user to danger and negate warranty.
