Troubleshooting
Temperature controllers do not illuminate when power switch is
turned on:
»
Check electrical power connections to the system.
»
Check the electrical fuse.
Temperature controllers illuminate, but the gas is not heating:
»
Check to ensure that the inlet gas supply is between 25 and
50 psi (SPE Dry 96) or 25 and 60 psi (SPE Dry 96 Dual).
»
Check to ensure that the system flow
rate is greater than 25 L/min.
»
Check that the gas temperature is set above ambient.
Temperature controllers do not illuminate, but power switch
indicator is on:
»
The heating units may be overheated. Turn off power
and let the system cool off for 10 minutes, ensure
proper airflow, then re-start. If problem continues,
please contact Biotage 1-Point Support.
No gas emits from the needles:
»
Check that the inlet gas supply pressure is set between 15
and 50 psi (SPE Dyr 96) or 15 and 60 psi (SPE Dry 96 Dual).
»
Check that the gas flow is set correctly.
»
Ensure that the needle assembly is seated
and locked down properly.
»
Check for leaks at the hose inlet and in the supply hose.
»
Visually inspect needle assemblies to
ensure they are not plugged.
Certain wells do not dry down:
»
Visually inspect that the needles are not blocked;
see the Maintenance section on page 6.
»
Check that the needles are not bent or damaged.
»
Inlet and/or operating pressure may be too low. For
more uniform drying, a higher inlet line pressure
(above 20 psi) and flow rate is optimum.
Difficult lower head movement:
»
Visually inspect all of the sliding
mechanisms for obstructions.
»
Ensure that the sliding guides are clean and lubricated.
»
Loosen the sliding arm knurled knob 1/4 to
1/2 turn further (counterclockwise).
Difficult to reach upper head flow rate of 80 L/min (only
applicable for SPE Dry 96 Dual):
»
Reduce lower head flow rate to system minimum of 25 L/min.
