Cold Start Function; Auto Fault Recovery - Comtech EF Data CSAT-5060 Installation And Operation Manual

100Watt C-Band Transceiver
System Operation
3.3.10 C S
OLD TART
The CSAT provides an optional 'Cold Start' feature that will ensure that the internal
10MHz reference signal is at a stable temperature prior to allowing the RF and IF outputs
to be turned ON. A fixed cold start interval of 15 minutes is used.
• If 'Cold Start' is ON when the CSAT is powered ON, the IF and RF outputs will
remain muted for 15 minutes even if all the conditions defined in 3.2.5 are
satisfied. At the end of the 15 minute interval, the RF and IF output will
automatically be turned ON if the conditions of 3.2.5 are met.
• If a CSAT was powered ON with 'Cold Start ON', the operator can override this
function by setting 'Cold Start OFF'.

UTO AULT
This parameter defines how the CSAT responds to momentary fault conditions.
• If 'Auto Fault Recovery' is OFF and a fault condition occurs that causes either the
RF or IF output to be muted, then that fault condition clears, the CSAT will
remain muted. In this mode, operator intervention is necessary to return the CSAT
to normal operating mode.
• If 'Auto Fault Recovery' is ON and the same situation occurs, the CSAT will
automatically be unmuted and return to normal operating mode. To protect
against repetitive, momentary faults, if the CSAT experiences five occurrences of
the same fault, the 'Auto Fault Recovery' parameter will automatically be set to
OFF.
Example: If the Up Converter IFLO synthesizer goes unlocked and starts
sweeping while Auto Fault Recovery is ON, the CSAT would see a unlocked /
locked condition at the sweep rate of the IFLO synthesizer. After the 5th
occurrence the firmware will set Auto Fault Recovery to OFF and keep the
CSAT RF output muted.
