2.8 SYSTEM WARNINGS
The TCR-U/L-50 has built-in monitoring for voltage, current, and temperature. This section
identifies warnings which are indications of improper operating conditions and may cause the
amplifier to limit output power or shut down, as described.
2.8.1 HIGH TEMP ALERT
If the amplifier internal temperature sensor detects excessive heat, the warning message “HIGH
TEMP ALERT, TX PWR REDUCED” will be displayed for two seconds and repeated every
six seconds until the condition is cleared. Upon clearing, “HIGH TEMP CLEAR, TX PWR
NORMAL” will be displayed for two seconds and the amplifier will return to normal
operations.
2.8.2 HIGH TEMP FAULT
If the amplifier is in a high temp alert and continues to increase internal temperature beyond
safe operating conditions, the warning message “HIGH TEMP FAULT, PA IN BYPASS
UNTIL TEMP IS REDUCED <65 C” will be displayed for two seconds and repeated every six
seconds until the condition is cleared. Upon clearing, “HIGH TEMP CLEAR, TX PWR
NORMAL” will be displayed for two seconds and the amplifier will return to the previous
operating mode.
2.8.3 HIGH CURRENT ALERT
If the amplifier high current protection circuit detects high current, the warning message “HIGH
CURRENT, CHECK SYSTEM” will be displayed until the end of transmit or two seconds,
whichever is less. Transmit power may be automatically reduced when high current is detected
but the PA will otherwise continue to operate normally.
2.8.4 HIGH CURRENT FAULT
If the amplifier high current protection circuit detects high current and cannot reduce the current
sufficiently by reducing TX power, the PA will switch to Bypass Mode and the warning
message “HIGH CURRENT, PA IN BYPASS” will be displayed for two seconds and repeated
every six seconds until the condition is cleared by changing modes or with a DC power cycle.
If in bypass or receive modes and excessive current draw is detected, the PA will automatically
power itself off and set the auto-start configuration to off. Auto-start will not be enabled until
selected again in the user accessible menu.
2.9 TROUBLESHOOTING
In the event of an amplifier malfunction, check to make sure that the equipment is configured in
accordance with Section 3. If the problem persists, refer to the troubleshooting guide in Table
2- 3.
