Runtime Error Messages

Appendix C lists other error messages that may appear at runtime. Some of these messages will also appear on the front panel when the Prot key is pressed. To clear the error, you must remove the condition that caused the error and then press the Prot Clear key.

Error

Overvoltage

Overcurrent Overtemperature Remote inhibit

+sense open - sense open +/- sense open sense open

Table 4-2. Runtime Error Messages

Description

an overvoltage condition has occurred an overcurrent condition has occurred

an overtemperature condition has occurred

a remote inhibit signal has been applied to the RI input a positive sense or load lead is open

a negative sense or load lead is open

a positive and negative sense or load lead is open

incorrect voltage reading on the sense leads, the unit may need to be recalibrated

If the front panel display shows OVLD , this indicates that the output voltage or current is beyond the range of the meter readback circuit. If this is the case, check that the setting of the output compensation is correct for the phone you are testing. If the front panel display indicates ---------- , an GPIB measurement is in progress.

Line Fuse

If the dc source appears "dead" with a blank display and the fan not running, check your ac mains to be certain line voltage is being supplied to the dc source. If the ac mains is normal, the fuse may be defective.

Refer to Appendix E and follow the procedure described in the appendix for accessing and replacing the line fuse located inside the unit. Do not change any of the line voltage connections.

NOTE: If the dc source has a defective fuse, replace it only once. If it fails again, the dc source requires service.
