ALL PROTECTION
ERROR REF: The Amplifier will stop transmitting when REF is >125 Watts. For
recovery, decrease power input or check the antenna - press RESET.
ERROR LP FILTER: The Amplifier will stop transmitting when lower segment is
selected in error. For recovery, check the selected segment and press RESET.
ERROR PWR 700 WATTS: With continuous carriers of >700 watts for more than
8 seconds, the amplifier stops transmitting. For recovery, reduce RF input and
press RESET.
ERROR PWR: The amplifier will stop transmitting if the output power is >1400
watts. For recovery, reduce RF input and press RESET.
ERROR HI CURRENT: The amplifier will stop transmitting if the drain current is
>37 amps, or REF is high. For recovery, reduce RF input and press RESET.
ERROR HI VOLTAGE: The solid-state switch does not deliver if the voltage is >55
volt. For recovery, turn amplifier off/on; if the problem persists, there is a fault in
the device.
ERROR TEMP: If the temperature is >65°C, the system goes to Cool Down; the
recovery point is <55°C.

Despite the robust build of an LDMOS PA, it is necessary to protect the circuits
to avoid damage caused either by user error or accidents. This ensures correct
handling by the user and extends the life of the device.
The error indicator area (1) shows several errors on the same tab (2).
