Table 2-3. Troubleshooting Guide
SYMPTOM PROBABLE CAUSE CORRECTIVE ACTION
“HIGH TEMP
ALERT”
The amplifier has exceeded its normal
operating temperature. Provide additional airflow or
reduce transmission time.
"HIGH TEMP
FAULT" The amplifier has exceeded its normal
operating temperature limit. Provide additional airflow or
reduce transmission time.
“HIGH CURRENT,
CHECK SYSTEM” The amplifier high current protection
circuit has detected high current. Reduce input power, check
antenna connections, reduce
output power setting.
“HIGH CURRENT,
PA IN BYPASS” The amplifier high current protection
circuit has detected high current beyond
the factory determined threshold. Reduce input power, check
antenna connections, reduce
output power setting.
3.0 INSTALLATION
3.1 PREPARATION FOR USE
After unpacking the system and inspecting for physical damage, select an appropriate location
for the amplifier. Although the TCR-U/L-50 is weather-resistant, placing it in a location where
it is protected from rain, sunlight, and salt spray will increase its service life. Make sure that
adequate air flow is available to allow proper natural convection cooling.
3.2 MOUNTING PROVISIONS
The TCR-U/L-50 can be mounted using existing mounting holes for the TCR-MBA-50
family of power amplifiers (refer to Figure 3-1). These holes accommodate #10-32 screws,
which screw into tapped 10-32 X 0.220 deep holes on the amplifier. Ensure the proper length
screw is used to prevent damage to the threaded holes on the amplifier.
The power amplifier can also be mounted by using two (optional) mounting tabs in the front and
two mounting holes on flanges in the rear. The tabs must be mounted first using 100° #8 flat
head screws. To mount the power amplifier, simply slide the two slots on the front of the power
amplifier onto the two tabs and secure the rear flanges with two #8 pan head screws. Other
mounting points are included on the sides of the amplifier to accommodate a variety of mounting
options.
See Figure 3-1 for details.
