This page pertains to the advanced system diagnostic features of the RCP controller.
LNA/LNB Faults refers to state of the controlled state of the LNA/LNB system. This
item shows the fault state of the individual LNA/LNB. If no faults are detected, the
word, “None” will be displayed. If fault tracking wasn’t enabled (e.g., if Track option set
to Ext – External faults only), the state will be indicated as “N/A” – Not Available. If any
LNA related faults are present in the system, this item will show them in format X-X-X,
where X could be the number 1, 2 or 3. For example, if LNA1 is in the fault condition,
the display will indicate “1----”; if all three LNAs are faulted, “1-2-3” will be displayed.
SSPA Faults refers to the state of the controlled state of the SSPA system. This item
shows the fault state of each individual SSPA. If no faults are detected, the word,
“None” will be displayed. If fault tracking wasn’t enabled (e.g., if Track option set to
LNA – LNA/LNB faults only), the state will be indicated as “N/A” – Not Available. If any
SSPA faults are present in the system, this item will show them in format X-X-X, where
X could be the number 1, 2 or 3. For example: if SSPA1 is in the fault condition, the
display will indicate “1----”; if all three SSPAs are faulted, “1-2-3” will be displayed.
PS1Out(V) indicates the output voltage of the RCP’s internal power supply 1. The
indicated value shows an instant reading of the power supply voltage with accuracy of
0.1V. Normally, this value should be in a range from 22V to 27V.
PS2Out(V) indicates the output voltage of the RCP’s internal power supply 2. Indicated
value shows instant reading of the power supply voltage with accuracy of 0.1V.
Normally, value should be in range from 22V to 27V.

Unit1; Unit2; Unit3 – Items refer to the summary fault state of individual units attached
to the RCP. The possible state is “Normal” for non-fault condition, “Fault” or “N/A” as
not available.
ExtFaults refers to the state of individual contacts on the RCP external input port. This
item has a subdivision for Auxiliary faults and major SSPA faults. Auxiliary faults are
represented as AuxXXX where X indicates the state of individual auxiliary fault sense
contacts and could be “1” for “open” state or “0” for shorted to ground state. The left-
most digit indicates the state of Auxiliary Alarm 3 contact and right-most digit shows
the state of Auxiliary Alarm 1. For example: if the display shows AUX101, it means
Auxiliary ports 1 and 3 are in “open” state (logic “1” state, not connected to the ground)
and port 2 is in logic “0” state and are “shorted” to the ground. The actual fault state
depends on RCP fault logic and fault handling.
