Note: A temperature fault is indicated if
the unit is
≤
-20
°
C or
≥
85
°
C. This
creates a summary fault and will cause
the unit to mute itself and switchover to
the back-up unit. However, the 9V
supply to the FET transistors will
remain on until the unit reaches the
thermal shutdown temperature of
≥
90
°
C. For protection reasons, the unit
will shutdown the 9V supply to the
power transistors at temperatures at
≥
90
°
C.
Summary Alarm
Status Summary Alarm:
Confirmation: <DEV/SAS_'cr'
>DEV/SAS_xx'cr'' lf'] Where: xx = Ok or FT
Summary Alarm is set to Fault (FT), if any
of items in Alarm Status are faulted.
Terminal Status
Change Configuration Status:
Confirmation: <DEV/TSC_'cr'
>DEV/TSC_nnn'cr'' lf'] Where: nnn = Yes or No
The TSC_ command can be used to
determine if the status of the terminal has
changed since it was last polled. If any of
the parameters listed in the RCS or RUS
commands have changed as a result of
user oprerations or if any new fault
conditions occur the TSC_ command will
return YES. The TSC_ command will then
continue to return YES until any of the
following commands are received: RCS_,
RUS_, RAS_, PACRCS_, PACRUS_, or
PACRAS_.
