ALARM
SILENCE
LIGHT APPROPRIATE ACTION/REMARKS
CUFF PRESSURE LOW:
15 mm Hg or more below
desired set point
STEADY
HIGH
PITCH
LO-P LIT This condition is generally caused by a leak
in the system, or a hose occlusion. All lines
and connections should be checked.
CUFF PRESSURE HIGH:
15 mm Hg or more above
desired set point
STEADY
HIGH
PITCH
HI-P LIT Normally caused by transient conditions
such as patient movement, controller
overshoot, or hose occlusion. This
condition, for an extended period, would
indicate a hardware failure and the
A.T.S. 2000 should be replaced.
CUFF SIDE LEAK:
A sustained leak exists that
may affect the cuff pressure.
STEADY
HIGH
PITCH
LEAK LIT A substantial leak has been present for
more than 9 seconds.
RESERVOIR LEAK:
An internal leak exists that
may affect the reservoir
pressure.
STEADY
HIGH
PITCH
RES LEAK LIT A substantial leak has been detected
which may indicate a leak has occurred
between the manifold and pump/reservoir.

TIME UP LIT Surgeon should be warned of time up
condition. On the advice of the surgeon‚
time should be set to a new value.
LOW BATTERY VOLTAGE STEADY
HIGH
PITCH
BAT LOW
PLUG IN
LIT Unit needs to be connected to A/C (~)
power.
CUFF PRESSURIZED
DURING POWER UP:
This will occur if, for
example, the unit is turned
off and back on without
deflating the cuff.
STEADY
HIGH
PITCH
CUFF INFL LIT If a cuff pressure is 50 mm Hg or greater
at the time that the ON/STANDBY touch-
switch is set to ON, the system assumes
that a procedure is in progress. It adopts
the sensed pressure of the cuff(s) as the
new cuff set point and sounds the alarm
to notify the operator that it has done so.
The operator should immediately check the
pressure set point to see if it needs to be
reset to a different value.
CUFF NOT DEFLATED STEADY
HIGH
PITCH
CUFF
NOT

LIT
NOTE: In addition to the conditions shown, it is conceivable that a malfunction could occur for which the indicators are unintelligible or
unpredictable.
It is very likely that the valves will be disabled causing the system to hold cuff pressure.
It is also likely that a high pitched tone
will be sounded under these conditions. The operator should conclude that a hardware failure has occurred rendering the unit unusable. The
appropriate action in such an event is to turn the unit off by pressing and holding the ON/STANDBY touch-switch until the unit turns off. Another
tourniquet system should be brought in and cuff hoses must be clamped off prior to changing units.
Pressure in the deflated cuff is a non-zero
value. Check for kinks in hose(s). If alarm
persists, disconnect hose(s) from cuff. If
attempting to set the unit to STANDBY,
ensure that cuff is
fully
deflated and has
been removed from the patient.
