Installing Optional Extension Modules
The data collector uses the Extension Manager to install and uninstall extension
modules. These extension modules are licensed and ordered separately from the
basic entry level product.
The installation Secure Digital (SD) cards that you receive work with any
Dynamix 2500 data collector. Once you have installed an extension module, the
card is locked so that it can be used only with that instrument.
You can uninstall extension modules if required. When uninstalling an extension
module, you have the option to free up the license so you can install the extension
module on another instrument. This makes the extension module available to be
transferred between units.
Install an Extension
Module
Follow these instructions to install an extension module.
1. Open the base cover at the bottom of the Dynamix 2500 data collector.
2. Place the extension module SD card contact side-up into the unit until it is
firmly seated in place.
3. Close the base cover.

IMPORTANT
One installation SD card is required for each instrument that needs to
be upgraded.
IMPORTANT
When ever you re-run the OS Loader software, you will re-load only the
main OS firmware. The OS loader will backup licence files and data, but
not the optional extension modules. Once you have updated the OS
firmware, install the latest version of your optional extension modules.
See the Dynamix 2500 Data Collector User Manual, 1441-UM001, for
more information.

Run Up/Coast Down Extension Module
The Run Up/Coast Down (RUCD) extension module is an optional module for
the Dynamix 2500 data collector. You install the extension module with the
RUCD Secure Digital (SD) card.
See Installing Optional Extension Modules on page 7 for installation
instructions.
The Run Up/Coast Down extension module lets the data collector record and
analyze data from intermittent events and transient vibration signals from
non-steady state machines.
The Run Up/Coast Down extension module is used to record and analyze data
from machines where noise or vibration levels are changing with speed or time
such as during a run up (increase in speed), coast down (decrease in speed), or
other applications causing transient phenomena. You use the data to analyze a
machine’s critical speeds and resonant frequencies.

Collect Run Up/Coast Down
Measurements
This section describes the Run Up/Coast Down status indicators and how to
collect Run Up/Coast Down data.
Once you have configured the parameters, you can begin collecting data. The
data is automatically recorded as a .wav file, which can then be analyzed using
several different types of plots.
1. Using the a tachometer cable, connect the reference input device to the
POWER/USB/TRIGGER connector and the transducer to connector A.
2. Align the reference input device (tachometer, optical tachometer, or
strobescope) to capture shaft speed.
Pulses/Rev The number of tachometer signal pulses per revolution of the
reference shaft.
To acquire a suitable tachometer signal, the tachometer signal must
be approximately 1.5 volts peak-to-peak. The adverse effect of
excessively short tachometer pulse widths can be addressed by
setting the Max No Order to a higher value to increase the sampling
rate.
