Error Msg Problem Troubleshooting steps
ERR 12V The circuit breaker on the KPA3 module may
be open. PA drops into bypass mode, fans
switch to level 2, and PAtemp display mode is
not available.
Check for short from PA module’s 12V
line to ground. If there’s no short, try
resetting the circuit breaker. If there is a
short, remove the KPA3 module. Set
CONFIG:KPA3 to PAIO NOR. While
waiting for a replacement, you can use the
K3 at reduced power.
ERR AT3 KAT3 not responding *De-install the KAT3 module (see above).
If this eliminates the error message, the
KAT3 may be defective. You can
substitute a KANT3 antenna input module
temporarily, if available.
ERR BP1 No response from RF board BPF shift registers *De-install option modules one at atime
ERR BP2 No response from KBPF3 option shift registers *De-install KBPF3 on RF board
ERR BP3 No response from sub RX BPF shift registers *De-install the KRX3 module, including
the SUBIN and SUBOUT boards
ERR BP4 No response from sub RX KBPF3 option *De-install the KBPF3 module on KRX3
ERR DS1 No main DSP SPI echo Reload DSP1 firmware
ERR DS2 Main DSP SPI echo not inverted Reload DSP1 firmware
ERR DS3 No AUX DSP SPI echo Reload DSP2 firmware. Note:
CONFIG:KRX3 must be set to NOT
INST unless the KRX3 option is installed,
which includes the aux DSP module
(DSP2) and 2
nd
synthesizer.
ERR DS4 AUX DSP SPI echo not inverted Reload DSP2 firmware. Note:
CONFIG:KRX3 must be set to NOT
INST unless the KRX3 option is installed,
which includes the aux DSP module and
2
nd
synthesizer.
ERR DSE Missing echo from a DSP command Reload DSP1 firmware (and DSP2
firmware, if applicable).
ERR DSX Extended DSP commandtimeout Reload DSP1 firmware (and DSP2
firmware, if applicable).
ERR EE1 On-chip EEPROM read/write test failed MCU may be defective (front panel).Try
re-loading MCU firmware first;then try
initializing parameters (pg. 61).
ERR EE2 External EEPROM read/write test failed EEPROM may be defective (front panel).
However, this message may also appear if
power isturned off/on too rapidly, or if the
power supply voltage “bounces” during
turn-on due to inadequate regulation. If the
power supply is not at fault, try re-loading
MCU firmware first;then try initializing
parameters (pg. 61).
ERR FW2 General firmware problem Try re-loading MCU firmware first; then
try initializing parameters (pg. 61).
