Troubleshooting the Rapid Sample Introduction System
4 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.
5 If the external power supply LED is illuminated while plugged into the
autosampler, cycle the autosampler power switch. The autosampler
sample probe should move up and the autosampler should initialize.
After initialization, the status LED on the front of the autosampler
should light up.
‣ If the cords are properly connected, power is available, the external
power supply is good, and the unit still does not initiate, continue
troubleshooting.
