MXC Quick Access keys are used to view transmitter parameters while the MXC is on-line and communicating with a transmitter (refer to Section 2). Eight Quick Access keys are used with the Model 344: TRANS. VAR'S., TREND, ZOOM, and STATUS, are available with the controller ON or OFF. CHANGE SP, CHANGE VALVE, A/M and TUNE are only available when the controller is ON. Press a key to access live transmitter data.

NOTE

Conserve battery power. Do not leave the MXC in the on-line mode.

1.Establish communication with a transmitter, see Section 3.2, and go to the On-Line Menu (adjacent).

2.Press a Quick Access key to view the desired transmitter parameter(s) at the On-Line Menu. The following paragraphs will describe how to view these parameters. TRANS. VAR'S. - displays updated on-line transmitter parameters. These parameters include the measured variable (MV), the current output (I), the process variable (PV) and their respective units or the Process (P), Set Point

(S) and Valve (V) controller variables.. Exit this screen by again pressing the TRANS. VAR'S. key or pressing END.

TREND - displays the adjacent screen to select the variable to be trended.

1)Press PREV or NEXT to toggle between Process Variable, Measured Variable, and Valve with the Controller “ON.”

2)Press SELECT to enter a value. Pressing END will exit this procedure and display the On-Line Menu.

3)Type the desired sample time: range 1-300 seconds; default is 1 second. Thirteen samples (maximum) of the variable can be shown while sampling at the sample time chosen.

If the sample time entered is greater than 300 seconds, a Warning message will appear that shows the range of values.
