Power System Problems

A possible cause of system malfunction is a problem in the power system. If the
system is not functional, it is possible that it is not receiving power. If this is the
case, the LED status indicator light will be off. To troubleshoot this problem,
complete the following steps in sequence until the problem is solved:
Check that the power switch on the autosampler is turned on.
1
Check that the power cord is plugged in firmly between the power input on the
autosampler and the external power supply and also between the power
2
supply and the wall outlet.
If the cable is plugged in, ensure that it is not damaged in any way.
Check that the LED on the power supply is illuminated.
3
If the LED is not illuminated, check the wall outlet using a device approved for
that purpose.
If the wall outlet is working and the voltage is acceptable, unplug the external
power supply from the autosampler, but leave it plugged into the wall.
 If the LED is not lit, the power supply is faulty and requires replacement.
