25.1 Simulated Phase Triggers

Use a simulated Phase Trigger (PT) under the following

conditions only.

• No physical speed sensor is installed.

• Your machine runs at a constant speed.

• 1X, 2X, nX amplitudes (at running speed) are

needed.

• Synchronous waveform (at running speed) is

needed

Create simulated PT from the Channels tab, Phase Trigger

view: Click “Add” and select simulated phase trigger:

Simulated Phase Triggers will be shown in the list of available Phase Triggers (Channels Tab,

Summary View) where they can be associated with a vibration channel.

Simulated Phase Triggers:

• Do not consume a channel

• Always show the simulated speed (even when machine is stopped)

• Do not have alarm or fault statuses

• Do not show as a bar graph on the VC-8000 front panel

• Cannot be used as a phase reference (associated channels will have invalid phase)

• Show on the display detail views

• Show in CMS

• Are not synchronized between UMMs

IMPORTANT!

A simulated phase trigger channel will always show the configured speed value

(i.e. 3600 RPM) - even when the machine is not running.
