Chapter 6

Alarm Setup

This chapter provides an overview on how to use the NI-FBUS
Configurator menus to configure alarms.

Note

If you are not using the NI-FBUS Configurator, reference the

documentation that came with your host system.

▲

Note

This chapter provides instructions using the NI-FBUS Configurator

menus, as this is the preferred way to configure the instrument. Move from
one step to the next in the configurator method window by clicking

Next

or pressing

Enter

. If your host does not support menus, reference

Appendix

for a list of DensityPRO parameters.

▲

Note

For detailed discussion on alarm parameters, reference the

DensityPRO user guide (P/N 717784).

▲

In the NI-FBUS Configurator, go to

AI_TRANSDUCER > 4 Alarm >

Alarm Setup.

When prompted, remove the loop from automatic control.

Select alarm number to set up:

You can configure up to eight alarms.

Enter the alarm number you want to configure now.

Alarm x set point:

Enter the set point (the measurement value at which

the alarm is activated).

Alarm x clear mode:

Select a clear point or deadband configuration. A

clear point is the exact measurement value at which the alarm is cleared.
A dead band specifies the span between the set point and the implicit
clear point.

Alarm x clr point/deadband:

Enter the clear point or deadband value.
