Description
The IO1A/FAULT input (AUX COMM 1) indicates a fault.
Monitoring for this fault is enabled using the EAM
command.
The IO2A/FAULT input (AUX COMM 2) indicates a fault.
The converter attached to UNIT 2 COMM (J6) has been
muted.
The +12.6 V LNA A (AUX COMM 1) power supply current
has exceeded the maximum limit of 350 mA and has been
disabled. The converter attached to UNIT 1 COMM (J3) has
been muted. The LNA power supply—and thus this fault—is
enabled using the LCS command.
This fault is cleared by a LCS command or power cycle.
The +12.6 V LNA B (AUX COMM 2) power supply current
has exceeded the maximum limit of 350 mA and has been
disabled. The converter attached to UNIT 2 COMM (J6) has
been muted. The LNA power supply—and thus this fault—is
enabled using the LCS command.
This fault is cleared by a LCS command or power cycle.
The +12.6 V LNA A (AUX COMM 1) power supply current is
outside the programmed window. (The power supply is not
disabled in response to this fault.) The converter attached to
UNIT 1 COMM (J3) has been muted. LNA current window
monitoring is configured and enabled using the LCS, CLC
and LCW commands.
This fault is cleared by a LCS command, CLC command,
LCW command or power cycle.
The +12.6 V LNA B (AUX COMM 2) power supply current is
outside the programmed window. (The power supply is not
disabled in response to this fault.) The converter attached to
UNIT 2 COMM (J6) has been muted. LNA current window
monitoring is configured and enabled using the LCS, CLC
and LCW commands.
This fault is cleared by a LCS command, CLC command,
LCW command or power cycle.
The External Reference Monitor has lost lock with the
external reference signal. All attached converters (UNIT 1
and UNIT 2) have been muted. Monitoring for this fault is
enabled using the XRF command.
when lock has been regained.
The IO1A/FAULT input (AUX COMM 1) indicates a fault.
Monitoring for this fault is enabled using the EAM-1X
command.
The IO2A/FAULT input (AUX COMM 2) indicates a fault.
Monitoring for this fault is enabled using the EAM-2X
command.
