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 prob-
lems related to BUC operation. The SSPA does not have a specific alarm
threshold for this voltage. Normal reading for this parameter should be in
range of 15V– 16V.
•
BUC PS2(V)
— This value represents secondary BUC power supply volt-
ages. For a unit equipped with a single power supply this value shows “N/
A” (not available).

The page shows advanced fault analysis information and advanced N+1 operation fea-
tures.
•
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
function 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 condition. 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 par-
allel 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;
•
LastFault
– This parameter shows information about the last detected
fault. The value is latched to the last fault occurrence. Use the Clear Fault
function to reset. Possible Values:
