The amplification is set first, then it is aligned with the zero position. The amplification is set with 25° tilt or Trendelenburg (electronic spirit level). The function not currently needed must be set to zero. The voltage on the distribution board between X or Y and the earth potential can be determined by a measuring device. The voltage values listed below are set with the appropriate amplifier control. After setting the amplification, the zero position is set to an accuracy of 0.3° by setting the controller (electronic spirit level). (See the wiring diagram for the measuring points and the controller arrangement.) NOTE! As the distribution board is fitted into the MARS endouro with a 90° turn, the wiring is modified accordingly. These modifications can be seen in the (MARS endouro) wiring diagram. Compensation values: Function Zero position Left tilting Right tilting Trendelenburg Antitrendelenburg

General Information

8.1.1

Emergency operating system The operating table is equipped with an emergency operating system in case a fault occurs (e.g. electronics error). The emergency operating system switches on automatically if the electronic control fails and this is indicated by: · The LED flashing above the green key on the column control panel. · The drives moving more slowly. During emergency operation: · The drive speeds are substantially reduced (around 35% less than in normal operation). · The operating table can only be controlled via the column control panel (IR and cable remote controls are inactive). Switching the operating table off: · This is also performed on the column control panel. · Briefly press (for a max. 200 of ms) the “Green” and “Zero” keys simultaneously (there is no other method of switching the table off).

Service Manual MARS 4 900 519 - 02/02

73

Appendices 8.1.2

Direct control of the drives If a fault occurs, it is possible to control the column and tabletop drives directly, without electronics. Direct control of the column drives: · This is done with 12 V direct current. · The motors are controlled via a direct control cable (item no. 4 100 153). Direct control of the tabletop drives: · This is done with 12 V direct current. · The voltage is applied directly to the motor connections (no special cable required). Direct control of the column drives 1. Pull the power supply cable out of the column and switch the column off. 2. Make the rear side of the electronics accessible (see repair manual). 3. Unscrew or pull off the plug of the drive and connect to the direct control cable. ATTENTION! There is a risk of damaging or destroying the drives. The end position sensors are not active when the drives are traversing. 4. The drive can be traversed by applying a voltage (12 V) to the direct control cable. 5. The direction of rotation of the motor depends upon the polarity of the voltage. Direct control of the tabletop drives 1. 2. 3. 4. 5. 6. 7.

Pull the power supply cable out of the column and switch the column off. Remove the pad from the seat section upwards. Unscrew the plastic plate from seat section (4 ball-headed screws M8). Remove the covering cap fastening screws (8 M4 screws). Pull the covering cap off. Cut the cable binders. Unclip the motor cables. ATTENTION! There is a risk of damaging or destroying the drives. The end position sensors are not active when the drives are traversing.

8. The drive can be traversed by applying a voltage (12 V) to the motor cable. 9. The direction of rotation of the motor depends upon the polarity of the voltage.

Appendices 8.1.3

Emergency adjustment of the column height If a fault occurs, it is possible to adjust the height of the column mechanically. This adjustment is made by turning the spindle directly. The use of the emergency adjustment device (item no. 4 700 318 is recommended for this. Emergency adjustment 1. 2. 3. 4. 5.

Pull the power supply cable out of the column and switch the column off. Remove the pad from the seat section upwards. Unscrew the plastic plate from seat section (4 ball-headed screws M8). Remove the covering cap fastening screws (8 M4 screws). Pull the covering cap off. ATTENTION! Risk of damage or destruction! The end switches are not active while traversing with the emergency adjustment.

6. Insert the emergency adjustment device through the aperture of the receiving plate into the hexagonal bolt at the upper end of the lifter spindle. 7. Turn the emergency adjustment device by means of a battery screwdriver or similar tool. 8. The direction of movement depends upon the direction of rotation of the emergency adjustment device.

Service Program (PC) ATTENTION! The service program (item no. 4 900 833) may only be used by authorised persons. The basic principle is that, for safety reasons, it may not be used if there is a patient on the operating table or if any other persons could come to harm. Furthermore, do not initiate any actions on the operating table unless you have direct visual contact. In exceptional cases (modem operation) it is possible to allow an action to be observed by someone else. This person must be in direct contact (visual or aural) with the user. System requirements:

Modem Connection The following conditions have to be fulfilled in order to create a modem connection: Hospital: • The modem must be connected to the operating table by the RS232 connecting cable (item no. 4 220 902). • The modem must be connected to a free, analog telephone line. • The modem must be connected to the mains supply (230 V). •

The green LED must light up.

Service partner: • The modem must be connected to the computer by the zero modem cable. • The modem must be connected to a free, analog telephone line. • The modem must be connected to the mains supply (230 V). • The green LED must light up. If the telephone number stored in the modem corresponds to that of the other connection, then a connection is made by pressing a button on one of the two modems. If the stored telephone number does not correspond, then a connection can only be made with the service software, see section 8.6.1.

Updating the Software It may be necessary to update the operating table software in certain cases. However, it is not necessary to regularly spool in new software. The control software can be spooled into the operating table from a PC or laptop with the aid of a connecting cable (item no. 4 220 902) and the flash adapter (item no. 4 144 998).
