Instruction Manual

MACV-1 and MACI-1 — Analog Outputs

The MACV-1 and MACI-1 Controllers offer two independent analog outputs. See

Figure 5-9.
For Analog Output #1 and Analog Output #2, each output is assigned to one of six

analysis modes, which are selected via the Edit PSF Screen of the supplied software.

Once the Analysis Mode Selection is specified for Meas1 and Meas2, the Analog

Output can specified via the Analog Output choices. The analysis mode is selected

as Meas1, Meas2, or Disabled. The Disabled option means the output is not utilized.

Meas1 and Meas2 reflect the choices provided with the Analysis Mode Selection. The

Scan # provides a means to average from 1 to 9 scans before the analog output gets

updated. The Invert option changes the output from a rising signal to a falling signal.

Null/Span Adjustment

The user can adjust both the zero and full-scale reading for both analog outputs of

MACV-1 and MACI-1 Controllers. This adjustment is implemented via the Edit PSF

screen

Null/Span

button, which activates the Null/Span menu (Figure 5-12).

Figure 5-12. Null/Span Menu

The Null/Span menu causes the controller to temporarily respond to scaling

adjustments. The Null and Span ranges can be adjusted as follows:

Each output’s Null and Span is independently adjusted via the separate sliding bars.

When the adjustments are made, the new values can be temporarily monitored by

selecting either the

Null Update

or

Span Update

button. The

OK

button saves the

new settings and instructs the controller to resume normal operation. Clicking the

Cancel

button disregards any Null/Span adjustments and causes the controller to

resume normal operation with the the previously saved null and span settings.
The MAC controller has a four-minute Null/Span time-out feature that causes the

controller to leave the Null/Span adjustment procedure when neither the Null Update

nor the Span Update functions are accessed. When this time-out condition occurs, the

MAC controller automatically cancels the Null/Span adjustment procedure and returns

to the previously saved settings.
