Troubleshooting
This fault finding guide should be used by the HS40 Compact user before they consult HyQuest Solutions to assist with
specific problems.
HS40 Compact Not Powering Up
§
Check battery voltage.
§
Check battery POWER and GROUND connections to the battery – make sure
they are done up tightly and there is no corrosion.
The compressor doesn’t start
when I connect the power
§
Check the state of the Condor pressure switch, and make sure it is set to the
‘1’ position.
§
The compressor should only start if the pressure is below 400kPa – or the
HS40 power was disconnected before it had reached the 750kPa level
(maybe it stopped due to battery LV, or pressure leak and then the battery
was disconnected.)
§
Check the battery voltage with your multimeter – if it is below 12V, then
maybe the controller locked out the compressor as the voltage fell below
10V, and the voltage has not yet risen above 12V to re-enable the
compressor. (Make sure the minimum battery capacity is 38Ah)
The compressor doesn’t start
when the pressure falls below
400kPa (58psi).
§
Check the state of the Condor pressure switch, and make sure it is set to the
‘1’ position.
§
Check the battery voltage with your multimeter – if it is below 12V, then
maybe the controller locked out the compressor as the voltage fell below
10V, and the voltage has not yet risen above 12V to re-enable the
compressor. (Make sure the minimum battery capacity is 38Ah)
The compressor starts but then
cuts out before 750kPa (110psi)
is reached.
§
Check the battery voltage with your multimeter – if it dips below 10V while
compressor is on, then maybe the battery condition is suspect.
§
Check the voltage on the “POS” and “NEG” stud of the controller – these
should be the same as your battery voltage – if the voltage on these studs
drops when the compressor turns on (but the battery voltage looks OK), then
you are getting a voltage drop somewhere – maybe a lose connection on the
battery – or maybe the battery leads are too long or the battery cable gauge
is not heavy enough – see section
Extending the Battery Cables .
The compressor doesn’t stop at
750kPa (110psi)
§
There is a fault with the Condor pressure switch adjustment. Contact HyQuest
Solutions for the adjustment procedure.
Can I check the check the
pressure transducer calibration
through the bubble rate test
port ?
§
You may be familiar with this feature in the HS40 Series I or HS40 Series II –
but this was removed from the HS40 Compact – so the answer is no, you
cannot check the pressure transducer calibration through the bubble rate test
port!
