Operation 3000ZA Teledyne Analytical Instruments 28 Operation 4.1 Introduction Once the analyzer has been installed, it can be configured for your application. To do this you will: • Set system parameters. • Establish a security password, if desired, requiring Operator to log in.
Trace Oxygen Analyzer Operation Teledyne Analytical Instruments 29 4.2 Using the Data Entry and Function Buttons Data Entry Buttons: The __ arrow buttons select options from the menu currently being displayed on the VFD screen. The selected option blinks.
Operation 3000ZA Teledyne Analytical Instruments 30 Figure 4-1: Hierarchy of Available Functions Any function can be selected at any time by pressing the appropriate button (unless password restrictions apply). The order as presented in this manual is appropriate for an initial setup.
Trace Oxygen Analyzer Operation Teledyne Analytical Instruments 31 4.3 The System Function The sub fuctions of the System function are described below. Specific procedures for their use follow the descriptions: • Auto-Cal: Used to define an automatic calibration sequence and/or start an Auto-Cal.
Operation 3000ZA Teledyne Analytical Instruments 32 4.3.1 Tracking the Oxygen Readings during Calibration and Alarm delay The user has the option of setting the preference as to whether the analog outputs track the display readings during calibration or not.
Trace Oxygen Analyzer Operation Teledyne Analytical Instruments 33 The factory default is three minutes, but the delay time is programmable. To adjust to delay time use the Left or Right arrow keys. When the time displayed on the second line blinks, it can be adjusted by Pressing the Up or Down keys to increase or decrease its value.
Operation 3000ZA Teledyne Analytical Instruments 34 Zero) OFF/ON field. Use __ arrows to set the OFF/ON field to ON. You can now turn these fields ON because there is a nonzero span interval defined.
Trace Oxygen Analyzer Operation Teledyne Analytical Instruments 35 The screen prompts you to enter the current password. If you are not using password protection, press Enter to accept TETAI as the default password.
Operation 3000ZA Teledyne Analytical Instruments 36 Enter the password using the __ arrow keys to move back and forth between the existing password letters, and the __ arrow keys to change the letters to the new password. The full set of 94 characters available for password use are shown in the table below.
Trace Oxygen Analyzer Operation Teledyne Analytical Instruments 37 If an alarm is tripped, the second line will change to show which alarm it is: 0.0 ppm Anlz AL—1 Note: If you log off the system us.
Operation 3000ZA Teledyne Analytical Instruments 38 TRAK/HLD Auto—Cal PSWD Logout More Use the __ arrow keys to blink More , then press Enter . Version Self—Test Use the __ arrow keys again to move the blinking to the Self–Test function. The screen will follow the running of the diagnostic.
Trace Oxygen Analyzer Operation Teledyne Analytical Instruments 39 TRAK/HLD Auto—Cal PSWD Logout More Use the __ arrow keys to blink More , then press Enter . Version Self—Test Show_Negative=NO Use the __ arrow keys and select “ Show_Negative = NO”.
Operation 3000ZA Teledyne Analytical Instruments 40 If you are using password protection, you will need to enter your password to gain access to either of these functions. Follow the instructions in sections 4.3.3 to enter your password. Once you have gained clearance to proceed, you can enter the Zero or Span function.
Trace Oxygen Analyzer Operation Teledyne Analytical Instruments 41 The zeroing process will automatically conclude when the output is within the acceptable range for a good zero. Then the analyzer automatically returns to the Analyze mode. 4.4.1.2 M ANUAL M ODE Z EROING Press Zero to enter the Zero function.
Operation 3000ZA Teledyne Analytical Instruments 42 CELL FAIL/ ZERO HIGH Before replacing the cell: a. Check your span gas to make sure it is within specifications. b. Check for leaks up-stream from the cell, where oxygen may be leaking into the system.
Trace Oxygen Analyzer Operation Teledyne Analytical Instruments 43 Use the __ arrow keys to enter the oxygen-concentration mode. Use the __ arrow keys to blink the digit you are going to modify. Use the __ arrow keys again to change the value of the selected digit.
Operation 3000ZA Teledyne Analytical Instruments 44 Press Enter to enter the span value into the system and begin the span calibration. Once the span has begun, the microprocessor samples the output at a predetermined rate. It calculates the difference between successive samplings and displays this difference as a Slope on the screen.
Trace Oxygen Analyzer Operation Teledyne Analytical Instruments 45 4.5 The Alarms Function The Model 3000ZA is equipped with 2 fully adjustable concentration alarms and a system failure alarm. Each alarm has a relay with a set of form “C" contacts rated for 3 amperes resistive load at 250 VAC.
Operation 3000ZA Teledyne Analytical Instruments 46 back to non-alarm conditions. This mode requires an alarm to be recognized before it can be reset. In the non-latching mode, the alarm status will terminate when process conditions revert to non-alarm conditions.
Trace Oxygen Analyzer Operation Teledyne Analytical Instruments 47 To set the other parameters use the __ arrow keys to move the blinking over to the desired parameter. Then use the __ arrow keys to change the parameter. Once the parameters for alarm 1 have been set, press Alarms again, and repeat this procedure for alarm 2 ( AL–2 ).
Operation 3000ZA Teledyne Analytical Instruments 48 L—10 M—100 H—250 Mode—AUTO Use the __ arrow keys to blink the range to be set: low (L), medium (M), or high (H). Use the __ arrow keys to enter the upper value of the range (all ranges begin at 0 ppm).
Trace Oxygen Analyzer Operation Teledyne Analytical Instruments 49 as established by the operator for that particular range, the output saturates at 1 VDC(or 20 mA). However, the digital readout and the RS-232 output continue to read the true value of the oxygen concentration regardless of the analog output range.
