Fault light
• Display shows “Autoset Fail”
when attempting to obtain Autoset
parameters for lamp intensity when
operating in Power or Current
operating modes.
The following conditions will cause the Autoset Fail error
message to display:
•
Cooler is not ready (most likely is caused by the cooler
cable not connected).
•
Lamp is not on.
•
No flux signal or saturated flux signal, causing the flux
signal to be out of range of 50uA to 2500uA.
The following corrective actions are recommended:
1.
Follow the steps in the Action procedure for Display
shows
“Cooler Not Ready” as described above.
2.
Confirm if lamp is ignited when Autoset button is pushed.
3.
Press the CLEAR button to clear the error message.
4. If the lamp is not currently ignited, ignite the lamp and
attempt to Autoset again.
If the Power Supply fails to Autoset, the flux reading of the LIK-
LMP
’s 71582 detector head out of the recordable range of the
power supply.
1. If the 71582 detector head is directly connected to lamp
housing switch to the other Disk with Aperture included
with the LIK-LMP.
2. If the 71582 detector head is external from the lamp
housing, adjust the position of the detector head (distance
from light source, filtering if applicable, etc.) to make the
flux output within range of the power supply.
If using RS232 or USB method of external control, the command
“FAULT?” can be used to determine the cause of Autoset failure.
Each corresponding bit, when set, indicates the corresponding
fault:
•
Bit3: Cooler is not ready (most likely is caused
by the cooler cable not connected).
•
Bit9: Lamp is not on.
•
Bit4: No flux signal (Flux reading is less than
0.2uA even at the highest gain of 1000).
•
Bit5: Saturated flux signal ( Flux reading is at
full scale even at lowest gain of 1).
•
Bit2: Flux signal is out of range of 50uA to
2500uA.
Using the FAULT? command will allow the user to determine the
cause of Autoset failure more efficiently.
