Power System Problems
A possible cause of ASXPRESS PLUS Rapid Sample Introduction 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, both of the LED
status indicator lights will be off. To troubleshoot this problem, complete the
following steps in sequence until the problem is solved:
1 Check that the power switches on the autosampler and ASXPRESS PLUS
electronics module are both turned on.
2 Check that the power cords are plugged in firmly between the power input on
the ASX
PRESS PLUS electronics module and the external power supply and also
between the power supply and the wall outlet.
If the cable is plugged in, ensure that it is not damaged in any way.
3 Ensure that the ASXPRESS PLUS valve/pump module cable is connected to the
ASX
PRESS PLUS electronics module.
If the cable is plugged in, ensure that it is tightened properly and not
damaged in any way.
4 Check that the autosampler is plugged in.
5 Check the external power supply (autosampler). The green LED on the power
supply should be illuminated.
a. If the power supply LED is not illuminated, check the wall
outlet:
• Using a Volt-Ohm meter or equivalent, check the wall outlet for
100-240VAC, +/- 10%, 50/60 Hz.
• The power supply has a green LED which should be lit if the
power supply is plugged into a wall outlet that is active.
b. If the voltage is acceptable, the cord is plugged in properly and
the external power supply green LED is still not illuminated,
unplug the external power supply from the autosampler, but
leave it plugged into the wall.
• If the green LED is not lit, the power supply is faulty and requires
replacement.
• If the green LED is lit when unplugged from the autosampler but
turns off when plugged into the autosampler, the autosampler
may have an internal short and requires repair.
6 If the external power supply LED is illuminated while plugged into the
autosampler, cycle the autosampler power switch. The autosampler sample
