1.0 INTRODUCTION The ANAFAZE SYSTEM 32 is the key element used to form an innovative measurement and control system. It combines its power with an IBM PC or similar computer to deliver an extremely efficient data acquisition and process control system. The SYSTEM 32 concentrates its power in analog measurement, independent digital loop control, alarm monitoring, and signal processing. This frees the computer to perform process control supervision including: graphic process displays, operator

1.1.3 PROCESS INTEGRITY: The ANAFAZE approach delivers high integrity because the SYSTEM 32 independently controls and checks each loop for alarms while it is in turn checked by the computer. Thus a computer failure will not affect the process and a controller problem will be detected by the computer. Further integrity is built in to the SYSTEM 32 since it has EEROM memory to protect control and alarm parameters. A watchdog timer with digital output adds to process integrity. 1.1.4 MULTIPL

Configurations can start with only the PROCESSOR I/O MODULE to provide 32 time proportioning or on/off open loop control outputs. For closed loop control, simply add an ANALOG INPUT MODULE, either reed relay for 16 inputs, or solid state for 32 inputs. A plug in ANALOG OUTPUT MODULE provides 16 analog control outputs. Systems can be matched to different applications by combining the following modules: 1.2.1 PROCESSOR I/O MODULE: The on board microprocessor performs all necessary control calcul

1.2.2 ANALOG INPUT MODULES: Two optically-isolated analog input modules are available for the SYSTEM 32. A 16 channel reed relay switching module and a 32 channel solid state switching module. The reed relay module provides the highest level of input noise protection and the solid state module is more economical. The two types of input modules can be mixed in a single controller. Allowing up to 48 channels of reed relay inputs, 96 channels of solid state inputs , or any combination such as

line, real-time data for each input can be graphically plotted on the screen. Data is continuously stored for every input to provide a history over user selected time intervals. These on line plots enable quick analysis of process conditions for optimizing performance, tuning control loops, determining reasons for alarms, and other situations. 1.3.2 TUNING AND PROCESS SET UP: The password protected tune menu displays necessary data for efficient tuning since it displays real time process info

3.0 INSTALLATION There are some precautions that must be observed when installing SYSTEM 32: WARNING: ELECTRICAL SHOCK DANGER It is very important that all system power including the power input be disconnected before servicing the ANAFAZE SYSTEM 32. HIGH VOLTAGE MAY BE PRESENT EVEN WHEN POWER IS TURNED OFF. To reduce the danger of electrical shock always mount the SYSTEM 32 in an enclosure that prevents personnel contact. Since the ANAFAZE SYSTEM 32 can make measurements of input signals

3.1.3 DETACHABLE TERMINAL BLOCKS WARNING - ALWAYS CHECK TERMINAL LOCATION AND ORIENTATION All connections, except the Ac power supply, are made on removable terminal strips. Terminal strip removal is achieved by removing the retaining screws and pulling them directly away from the front panel. The terminal strips must be carefully installed in the correct position and not up side down. 3.2 CONFIGURATION WARNING - TURN OFF POWER BEFORE CHANGING SWITCH The unit configuration switch is located

3.2.2 COMMUNICATIONS WATCHDOG TIMER The communications timer provides a method of turning off all control outputs if there is a problem in the host computer that effects communication. It operates by monitoring activity on the communication line. If this controller has not been contacted within the time interval, it automatically sets all control outputs to manual with zero outputs. A dedicated digital output is set when the watchdog times out. WARNING: IF THE COMMUNICATIONS WATCHDOG IS ENABL
