TM 5-3895-374-24-2 955-257 AN INTRODUCTION The introduction of microprocessors into panel mounted 1/4 DIN size controllers has resulted in control instruments with exceptional application flexibility. However, this broad capability can be very confusing to those not familiar with this new technology. This manual is written to take you step by step through the installation, set-up, operation and recalibration of this microprocessor based controller.  Attention to this manual will help ensure a successful application. The  controller  contains  a  unique  alphanumeric  display  that  actually  shows  key  words  as  well  as  numerical  information. Also on the front of the controller is a six key operator interface.  All operator communications are done through the front keypad.  There  are  no  internal  jumpers,  switches  or  pots  to  set  or  adjust.    When  you  push  the  appropriate  key,  the controller will scroll through a display routine to provide the information you need for complete tuning and proper operation as well as recalibration if required. All instruments covered by this manual  are  3-Mode  PID  controllers  with  ON/OFF, time proportional or analog output(s). They accept one thermocouple, RTD, voltage or current input including process inputs.  The control output(s) can be solid state relay(s) or analog output(s).  Optional Alarm/Timer relay(s) may also be included. Models  2003  and  2004  include  a  SELF  TUNE  feature  which  automatically  calculates  the  appropriate  PID  values  during start-up or upon command during normal operation thereby eliminating the  need for manual tuning. You  initiate the  SELF TUNE program from the front keypad by responding to a sequence of displayed questions. These  controllers are unique in  that  they  not  only  automatically  compute  the  PID  constants  but  will  also  show  you  those  values  on  the  alphanumeric display.  You can use these calculated PID values or you can manually change any of them as circumstances require. You  can  familiarize  yourself  with  this  controller  prior  to  installation  by  attaching  a  properly  protected  (cover  exposed terminals)  AC  power  cord  to  terminals  6,  7  and  8  and  a  100  ohm  resistor  between  the  input  terminals  F  and  H.    The measurement on the display will be incorrect but all routines and displays will function properly.  As you read this manual you can follow the functions right on the controller display.  You cannot harm the controller by pushing any keys.  Special care  is  required  when  in  the  calibration  routine  so  as  not  to  erase  the  factory  set  calibration.    Follow  the  instructions carefully. Recalibration is covered in Section 6. After reading the instructions, if you have any questions please contact our Sales Representative or  the factory. We  know that you will be pleased with the operation of this controller Models 2000, 2001 and 2003 controllers include a STOP/START key function. Models 2002 and 2004 controllers include an AUTO/MANUAL key function. WARNING: IN    ANY    CRITICAL    APPLICATION    WHERE    FAILURE    COULD    CAUSE  PRODUCT  LOSS OR    ENDANGER    PERSONNEL,    A    SECOND    INDEPENDENT    LIMIT    CONTROLLER    IS RECOMMENDED.
