The main control unit can 

Monitor and control the power module



Monitor the table-top position through sensors and limit switches



Open and close oil pumps and valves.

2.2.2 Man-machine Interface The man-machine interface consists of the corded hand-control and the override control panel, both of which provide keys and LED indicators for input/output purposes. The figure blow shows how the corded hand-control works. It detects the key signals and sends them to the main control unit through the RS232 interface. Also, it displays the system status signals through the LED indicators.

2-3

Introduction

The override panel works in a way sim ilar to that of the override panel, except it also provides an interface to the foot switch and a beeper. The figure below shows how it works.

2.2.3 Power Module The power module provides power for other components as well as charges the batteries. However, the two functions cannot be performed simultaneously, namely it charges the batteries only when the operating is not working. The block diagram of the module is shown in the figure below. When the mains supply is connected, the system automatically selects it over the internal batteries. The internal batteries work only when the mains supply is off. When the mains supply is connected, the system charges the batteries automatically if the operating table is not working. The module provides 5V outputs from electronic boards and 24V output for the pump and valves. The power at the bottom of the operating table can shut off the power module’s outputs to the boards, but it will not disable the battery charging function as long as the mains supply is connected.
