Sensor Fault
Temperature sensors not communicating,
possibly trigger occurring too frequen-
cy without arm ready check.
Any active fault will prevent the ChipSHOUTER from arm-
ing (prevents the high voltage charge from becoming active),
and the fault condition must be fixed before you attempt to
arm the device.
When a fault is active, the “FAULT” LED will be on. Do
not attempt to arm the device when a fault is active. Some
faults will also trigger a fault tone to make the error con-
dition clear.
If a device is already armed when certain critical
faults occur, the fault will latch and the device will dis-
arm. In this case it not enough to simply fix the condition.
In addition you must clear the latched fault after fixing
the error condition. This latch prevents the ChipSHOUTER
from automatically re-arming when an error occurs.
The latched fault can be cleared in two ways:
1.
Hold the “ARM” button down for 8 seconds, the Chip-
SHOUTER will either have 3 short beeps (
fault cleared
OK
) or one long tone (
fault could not clear as condi-
tion has not been fixed
).
2.
Using the serial port, the command
set fault none
.
Probe Disconnected Fault
The ChipSHOUTER looks for a low-impedance connection on the
SMA connector. This connection is used to detect that a
fault injection probe is attached.
