•
PSModFlts — For amplifiers utilizing an external N+1 power supply, this value
indicates the number of detected N+1 PS module faults. For units with an inter-
nal power supply, this value reads “000” and should be ignored. Check PS1 and
PS2 Voltage readings to assess the state of an internal power supply.
3.1.9 Sys Info Page 9 (version 6.00)
This page shows various miscellaneous operation parameters.
•
Chssy Temp — Chassis temperature reading measured by the control board.
Since the control board is typically located at rear of the chassis, this reading
correlates with the exhaust air temperature;
•
RecordHigh — The highest temperature detected over unit lifetime. This value
is updated each time a temperature higher than the current record is detected.
Value could be used for SSPAs problem troubleshooting. Record data is factory
reset only.
•
BUC PS1(V) — This value represents the power supply voltage used for biasing
an optional BUC unit. Voltage could be used for detecting problems related to
BUC operation. The SSPA does not have a specific alarm threshold for this volt-
age. Normal reading for this parameter should be in range of 15V– 16V.
•
BUC PS2(V) — This value represents secondary BUC power supply voltages.
For a unit equipped with a single power supply this value shows “N/A” (not avail-
able).
3.1.10 Sys Info Page 10 (version 6.00)
The page shows advanced fault analysis information and advanced N+1 operation features.
•
MuteFault – This parameter allows the user to check the SSPA mute condition.
Possible values:
○ Clear — No present fault mute condition on SSPA unit. Mute/Unmute func-
tion under full user control;
○ Set — One or more mute fault conditions present in the system. The unit is
forced to the Mute On condition.
•
MFltCause — Parameter allows user to determine last detected Mute fault con-
dition. Possible values:
○ None — No detected Mute fault conditions;
○ AuxFlt — Mute fault condition triggered by a detected Auxiliary fault.
○ ExtM — Mute condition forced by external signal applied on the parallel port
Mute input;
○ BUCFlt — Mute fault condition caused by a detected BUC fault;
○ PSFlt — The unit is forced to mute due to one or more failed N+1 power
supply modules;
○ N+1Flt — N+1 configuration forced unit into a mute state due to an internal
summary fault condition;
