Section 5.0. Programming the Analyzer - Basics

5.1General

Typical programming steps include the following listed procedures. Each of these programming functions are easily and quickly accomplished using the intuitive menu systems.

Configure and assign values to the current outputs

Set a security code for two levels of security access

Accessing menu functions using a security code

Enabling and disabling Hold mode for current outputs

Choosing the frequency of the AC power (needed for optimum noise rejection)

Resetting all factory defaults, calibration data only, or current output settings only

5.2Configuring and Ranging the Current Outputs

The T56 accepts inputs from two sensors and has four analog current outputs. Ranging the outputs means assigning values to the low (0 or 4 mA) and high (20 mA) outputs. This section provides a guide for configuring and ranging the outputs. ALWAYS CONFIGURE THE OUTPUTS FIRST.

To configure the outputs, access the Outputs screen by pressing ENTER/MENU then Program from the main screen. Outputs 1-4

can be set to Analog, PID or Simulation. Also, output assignments, scaling the range, linear or loga- rithmic outputs, output dampening, output setpoints and output fault levels can be set for each output if desired.

5.3Setting a Security Code

The security codes prevent accidental or unwanted changes to program settings, displays, and calibration. T56 has two levels of security code to control access and use of the instrument to different types of users. The

two levels of security are:

All: This is the Supervisory security level. It allows access to all menu functions, including Programming, Calibration, Hold and Display.

Calibration/Hold: This is the oper- ator or technician level menu. It allows access to only calibration and Hold of the current outputs.

The set security codes, access the Security screen by pressing ENTER/MENU from the main screen. Upon entry of the proper code, the follow security screen will appear.
