Source Errors
Source errors display in the Source Table of the ProTesT Control Panel
(see page 4-2). A Source error is typically due to problems with the load.
For example:
• Current is driven into an open circuit or high impedance.
• Voltage is applied across a short circuit or low impedance.
• Power requirements of the relay under test exceed the capacity of
the source.
If a source error occurs:
• The name of the affected source displays as ER and blinks in the
Source Table.
• The Amplitude and Phase fields for the affected source blink in
the Source Table.
• An audible alarm sounds from the speakers of the control PC.
Common source errors are defined in Table 6.6.
Missing/bad
(V AMP#2)
SLOT 10
The voltage amplifier in slot 10 is
either missing or bad.
Replace the voltage amplifier
board in slot 10. Refer to ”Circuit
Board Replacement”
on page 7-17.
Missing/bad HVPS The high-voltage power supply is
either missing or bad.
Check the power supply with a
voltmeter (see page 6-9). Replace
the board if necessary. Refer to
”Circuit Board Replacement”
on page 7-17.
Bad/Blank CPU
EEPROM
The CPU board is either bad or the
EEPROM has no data.
Replace the CPU board. Refer to
”Circuit Board Replacement”
on page 7-17.
