5.4Security Access

When entering the correct access code for the Calibration/Hold security level, the Calibration and Hold menus are accessible. This allows operators or technicians to perform routine mainte- nance. This security level does not allow access to the Program or Display menus. When entering the correct access code for All

security level, the user has access to all menu functions, including Programming, Calibration, Hold and Display.

To use T56 menus using a security code, access the Security screen by pressing ENTER/MENU from the main screen. If a secu- rity code is currently programmed, the follow security screen will appear. Enter the code.

1.If a security code has been

programmed, selecting the Calibrate, Hold, Program or Display top menu items causes the security access screen to appear

2.Enter the three-digit security code for the appropriate security level.

3.If the entry is correct, the appropriate menu screen appears. If the entry is incorrect, the Invalid Code screen appears. The Enter Security Code screen reappears after 2 seconds.

5.5Using Hold

To prevent improper operation of systems or pumps that are controlled directly by the current output, place the analyzer in hold before removing the sensor for calibration and maintenance. During hold, all outputs remain at the last value. Once in hold, all current outputs remain on Hold indefi- nitely. Be sure to remove the analyzer from hold once calibration is complete

To hold the outputs and alarm relays, access the Hold screen by pressing ENTER/MENU from the main screen.

5.6Resetting Factory Default Settings

This section describes how to restore factory calibration and default values. The process also clears all fault messages and returns the

display to the first Quick Start screen. The T56 offers three options for resetting factory defaults.

a.reset all settings to factory defaults

b.reset sensor calibration data only

c.reset analog output settings only
