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.
