CONFIGURING THE ZPU-5000 WITH ZOOM SOFTWARE
The properties of the ZPU-5000 unit, modules, and attached sensors can be edited through the ZOOM
Configuration program. Read the contextual help supplied with the ZOOM software for more information. The
two following sections are provided to explain how processing at module level.
4.1 Module firmware and spectral analysis processing
The CIM-4/20, ICPM-1.13, FIM-40-100, ICPM-5.65-500, and FIM-40-100(LF) acquisition modules can be
programmed with spectral analysis firmware designed for monitoring specific frequencies and protecting fixed
components on large rotating units.
4.2 Processes for Trend outputs
On most measuring chains, a type of signal processing is automatically applied on the trending output and
cannot be changed.
On some measuring chains, the type of signal processing is selectable. For instance, with the parameter
Velocity, the selected signal processing can be either RMS or Peak.
The eight types of processes that may be applied on the Trend outputs are:
Raw:
The output signal from certain types of measuring chains includes both AC and DC components. Slow
evolving parameters, such as temperature or meter levels, have an output signal with a slow DC
component. In such cases, the raw signal value may be selected for an unprocessed signal.
Air gap / Blade tip:
The minimum of each pole (or blade) is detected by the air gap pole detector. This
detector does not have a finite window as it uses the signal’s shape to find the corresponding minimum
for each pole (or blade).
RMS:
Some applications favor the use of RMS (Root Mean Square) values of acceleration and velocity
readings for vibration measurements. The RMS value process uses only the AC component of the
input signal.
Peak:
Some applications favor the use of the peak value of acceleration and velocity readings for vibration
measurement. The peak value process uses only the AC component of the input signal.
Peak-Peak:
Some applications favor the use of the peak-to-peak value of displacement readings for vibration
measurement. The peak-to-peak value process uses only the AC component of the input signal.
Maximum:
Some applications require the maximum value measured by a sensor. The maximum process
detects and returns only the maximum values during a predetermined time period.
Minimum:
Some applications require the minimum value measured by a sensor. The minimum process
detects and returns only the minimum values during a predetermined time period.
Average:
Some applications require the average value measured by a sensor. The average process
determines the average value during a predetermined time period.
