high power alarm enabled; If set, shows that the high power
alarm is enabled. See section 6.1.4 for details on enabling/disabling
and operation of the power alarms.
D3 power too low; If set, indicates that the low power alarm is set and
that the RF output power level is below the alarm level. The amplifier
will remain in the transmit mode, but the fault flag will only clear
once either:
i/ the RF output power level exceeds the alarm level or
ii/ the low power alarm is disabled (see section 6.1.4.1).
low power alarm enabled; If set, shows that the low power alarm
is enabled. See section 6.1.4 for details on enabling/disabling and
operation of the power alarms.
RF enabled; If set, shows that the RF is enabled. The RF enabled/
inhibited commands are accepted in any of the operational modes. See
section 6.1.7 for details on enabling/disabling the RF inhibit feature.
remote enabled; If set, shows that the amplifier is in the remote
mode, allowing control via the serial communications interface. See
section 6.1.12 for details on enabling/disabling the remote mode.
D4 heater current; If set, indicates that the amplifier has seen an
internal heater fault trip. The amplifier will revert to the off mode
automatically; prime power must be removed and re-applied to reset
the trip.
HV overload; If set, indicates that the amplifier has seen an internal
HV overload fault trip. The amplifier will revert to the standby mode
and automatically attempt to reset three times; for full reset details
see section 5.2.1.
PFC fault; If set, indicates that the amplifier has seen an internal
power factor corrector fault trip. The amplifier will revert to the off
mode automatically, prime power must be removed and re-applied
to reset the trip.
D5 external interlock; If set, indicates that the external interlock input
is asserted. This prevents the amplifier from entering the transmit
state until the input becomes unasserted. The amplifier will revert to
standby if the external interlock is asserted while in transmit (see
section 5.2.5).
reflected power; If set, indicates that the amplifier has seen an
excessive reflected power trip. The amplifier will revert to the
standby mode and automatically attempt to reset three times; for full
reset details see section 5.2.1.
mean helix current; If set, indicates that the amplifier has seen an
excessive mean helix current trip. The amplifier will revert to the
standby mode and automatically attempt to reset three times; for full
reset details see section 5.2.1.
peak helix current; If set, indicates that the amplifier has seen an
excessive peak helix current trip. The amplifier will revert to the
standby mode and automatically attempt to reset three times; for full
reset details see section 5.2.1.
