Transceiver
•  Transceiver shutdown temperature
The temperature of the transceiver is monitored. When the temperature exceeds the alarm limits or otherwise differs from the defined tolerances alarm messages will appear in the message.
•  Transceiver shutdown voltage
The high voltage supplied to the transceiver boards is monitored. You are not permitted to change the alarm limits. If this voltage differs from the defined tolerances, alarm message AKH11 will be initiated: Transmission is inhibited due to a high voltage in the power supply.
