14.5 Error messages:
FAULT
– The digital control system monitors how long it takes for the shelves to turn to the end
position switch. If the signal from the switch is late (or not sent at all) the control stops the turning
system and displays FAULT. This may be caused by:
Debris or incorrectly loaded trays. Clear any debris. Arrange eggs evenly (balanced from side to
side) and make sure the trays are pushed fully back. Switch the turning system back on (Section
9) and check the turning function.
Door not closed. Make sure the door is fully closed, switch the turning system back on (Section 9)
and check the turning function.
SENSOR ERROR
– The control system communicates to the temperature and humidity sensor with a
digital signal that under normal conditions is highly tolerant of external electrical disturbances.
However, if the signal becomes interrupted and cannot be recovered automatically the control displays
SENSOR ERROR. This may be caused by:
Strong electrical interference perhaps from a faulty appliance or lights. Restart the incubator and
try a different power socket or a “surge protector” type socket adaptor.
If the error message occurs again please contact Brinsea Products at the address at the end of these
instructions.
Observation
Likely Cause(s)
Solution(s)
No chicks hatch
Infertility, infection, drastically
incorrect incubation settings,
parent ill health.
Check egg viability
– are similar eggs hatching
naturally. Disinfect the incubator. Check
incubator settings and procedures
– particularly
temperature.
Chicks hatch earlier
than expected,
deformities.
Incubation temperature too high
Reduce incubation temperature slightly 0.5°C
(1°F)
Chicks hatch later
than expected
Incubation temperature too low
Raise incubation temperature slightly 0.5°C (1°F)
Hatch dates widely
spread
Different rates of development due
to different storage times,
incubation temperature variation.
Limit egg storage times. Check for incubation
temperature variation
– sunlight, large room
variation etc.
Late
stage ‘death in
shell’
Incorrect humidity, probably too
high.
Try reducing average humidity levels (but see
section 6 above)
Generally poor results
Incorrect incubation settings, poor
parent bird health, inadequate egg
turning.
Improve parent bird health, check all incubation
settings, analyse egg weight loss to confirm
humidity correct, check turning working correctly.
