3.14 Read Out and Reset Error/Failure Flags
The fail list (fail history) is only available in the password-protected
configuration setup*.
* For details please see chapter "Installation", "Configuration Setup" page 69.
3.15 Warning and Failure Indications
at intervals of 3 s
• The supply voltage of the transceiver is less than the threshold
adjusted in the configuration setup.
• The device is operable but it can have a decreased performance
depending on supply voltage.
Possible cause:
• Accumulator capacity problems
• Power interrupts.
• General power supply problems.
• Adjustment for low battery threshold too high.
at intervals of 3 s
• The transmit mode is automatically terminated (return to receive
mode) after 120 s of continuous transmitting.
• The transceiver goes back to receive mode also if the PTT line is
still active (GND).
Possible cause:
• Transmission continues more than 120 seconds. Frequent
overriding can decrease the MTBF.
• PTT-key is stuck.
• PTT line permanently grounded (short circuit in installation).
Notice: For the start of a new transmission it is necessary to set the /PTT line inactive
(open).
at intervals of 3 s
• "TX HOT" is shown if the internal device temperature is > +90 °C.
• Transceiver is still operable. The performance of transmitter is
decreased.
Possible cause:
• Very high environmental temperature, long transmissions times
and airflow conditions are not sufficient.
at intervals of 3 s
• The transceiver has found an internal failure during normal
operation.
• Depending on failure cause, the device is operable with decreased
performance, or not operable at all.
Possible cause:
• Specified environmental conditions.
• HW or SW failure inside the transceiver.
