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.
