7.2.7 Fault Lamp On
If the power source Fault lamp is on, the following may be at fault:
CAUSE SOLUTION
Ambient temperature is too high. Operate power source between 0 and
50
°
C.
Fan or ventilation holes are blocked. Remove obstructions.
Fan not working. Replace fan. Consult factory.
If the 2001RP is configured to operate in the Constant Voltage mode, the Fault lamp comes on
when the output load current has exceeded the programmed current limit value. If the AC
Power Source Fault lamp is on, the following items may be at fault:
CAUSE SOLUTION
The output is overloaded. Remove the overload.
The programmable current limit level is set
too low for the load being driven. Compute and reprogram the correct
programmable current limit level.
The programmable current limit is
incorrectly calibrated. Perform the calibration in Section 6.4.2
The Remote Sense lines are not
connected. On the Rear Panel Power Output terminal
block, connect terminal 2 to 3. Also
connect terminal 5 to 6.
7.2.8 Can’t Program AC Power System on GPIB or RS232
If the power source does not respond to IEEE-488 GPIB programming, the following items may
be at fault:
CAUSE SOLUTION
The power source unit address is
incorrect. Update address. See section 8.3.
GPIB or RS232 cable is loose at power
source rear panel. Check connection, tighten jackscrews.
RS232/GPIB Assembly has failed. Replace the RS232/GPIB Assembly.
7.3 Module Removal
Figure 7-1 shows the location of the internal modules and assemblies. The figure shows the
Amplifier Module, A7, with the insulator removed.
