6.8 Auto Limit Sensor (ALS) Check
The table is equipped with the Auto Limit Sensor
™
system (ALS) which provides instant user feedback on
conflicting tabletop articulations. An ALS Warning (refer Section 2.2, Hand Control Symbols) on the hand control
indicates the tabletop has been ordered into a configuration or has moved into a position that may cause tabletop
damage or patient injury.
To prevent a tabletop sectional conflict, or collision of tabletop with the table or floor, the ALS System immediately
stops the movement in process and the ALS LED lights. The control system alerts the user to an alternative
movement choice in the LCD Display.
NOTE: The ALS System suggested alternative movement is not the only movement available. Users should
exercise professional judgment in determining the most desirable movement.
Test the Auto Limit Sensor system as follows:
1. Review and follow instructions presented in S
ECTION 4, BEFORE USING THE TABLE, and prepare the table for
operation.
2. Raise tabletop to highest position possible.
3. Use SLIDE HEAD and move tabletop to head end limit.
4. Press LEG DOWN button until ALS Warning lights and tabletop motion stops. If system does not engage,
stop tabletop movement before collision and call STERIS.
6.9 LEVEL Check
Check the tabletop LEVEL function as follows:
1. Review and follow instructions presented in S
ECTION 4, BEFORE USING THE TABLE.
2. Press LEVEL pushbutton.
NOTE: When operating in REVERSE ORIENTATION, LEVEL function does NOT include the back section for
compliance with anesthesia procedures. Ensure REV. ORIENT (reverse orientation) is not active.
3. When depressed, tabletop is gradually returned to level or horizontal position by aligning tabletop sections in
following order:
a. KIDNEY Elevator and lateral tilt.
b. Trendelenburg and back.
c. Leg.
4. Use a level and ensure tabletop is level. If not, call STERIS.
6.10 Auxiliary Control Check
Check the STERIS 4095 General Surgical Table auxiliary control system as follows:
1. Review and follow instructions presented in S
ECTION 5, BACKUP (OVERRIDE) CONTROL SYSTEM and prepare the
table for auxiliary control system operation.
2. With tabletop at extreme low height, press HEIGHT UP pushbutton and pump pedal.
3. Ensure tabletop raises correctly. If not, call STERIS.
WARNING – PERSONAL INJURY AND/OR EQUIPMENT DAMAGE HAZARD:
The Auto Limit Sensor (ALS) System suggested alternative tabletop movement does not take into
account the type of surgery that may be in process or the environment (e.g., other equipment
close by) and might not be compatible with the surgical procedure. To avoid an action that could
result in death or serious injury to the patient and the operating room staff, and/or serious
equipment damage, completely evaluate the feasibility of the suggestion.
