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
The Wagtech incubator is designed to
provide field or static incubation of
microbiological cultures at 37 or 44°C.
Alternative uses will potentially expose
the user to danger and negate warranty.
