System Overview
STI’s CMCP7504 is a general-purpose monitoring system capable of continuously monitoring up to 4
channels of vibration, position or temperature. The CMCP7504 can be configured to operate as a
standalone protection system or it can be connected to a host device such as a PLC, DCS or SCADA
system. Local bar graph displays provide the overall amplitudes and alarm status along with a user
identifiable tag name.
Introduction to the CMCP7504
The STI CMCP7504 System is comprised of a series of sub-modules:
AA - Acceleration Module
VA - Velocity Module, Accelerometer Input
VV - Velocity Module, Velocity Sensor Input
EV - Enveloped Acceleration Module, Accelerometer Input
RV - Radial Vibration Module, Proximity Probe Input
TP - Thrust Position Module, Proximity Probe Input
AM - Analog Input Module, 4-20mA or 1-5 VDC Input
TM - Temperature Input, 100 Ohm Platinum RTD or 10mV/Deg. C
The (AA) Acceleration Module is for connecting to Piezoelectric accelerometer with a mV/g output.
The signal is processed for continuous monitoring and the overall amplitude is converted into a 4-
20mA output, proportional to the full-scale range selected, for transfer to a PLC, DCS or other facility
control system. Acceleration can be displayed in g’s with either RMS or Peak detection.
The (VA) Velocity Module is for connecting to Piezoelectric accelerometer with a mV/g output. The
signal is processed for continuous monitoring and the overall amplitude is converted into a 4-20mA
output, proportional to the full-scale range selected, for transfer to a PLC, DCS or other facility
control system. Velocity can be displayed in terms of either in/Sec or mm/Sec with either RMS or
Peak detection.
The (VV) Velocity Module is for connecting to Piezo-Velocity sensor with a mV/in/s or mV/mm/s
output. The signal is processed for continuous monitoring and the overall amplitude is converted
into a 4-20mA output, proportional to the full-scale range selected, for transfer to a PLC, DCS or
other facility control system. Velocity can be displayed in terms of either in/Sec or mm/Sec with
either RMS or Peak detection.
The (EV) Enveloped Acceleration Module is for connecting to a Piezoelectric accelerometer with a
mV/g output. The signal is processed to calculate an Acceleration Enveloping value within a selected
bandwidth, 0-1,000Hz (Filter #2) or 500-10,000Hz (Filter #3) for continuous monitoring and the
overall amplitude is converted into a 4-20mA output, proportional to the full-scale range selected,
for transfer to a PLC, DCS or other facility control system. Enveloped Acceleration can be displayed in
terms of gE.
The (RV) Radial Vibration Module is for connecting to eddy current probe systems (also referred to as
a proximity probe system) with a mV/mil or mV/mm output. The signal is processed for continuous
monitoring and the overall amplitude is then converted into a 4-20mA output for transfer to a PLC,
DCS or other facility control system. Radial vibration can be displayed in terms of mils or microns
Peak to Peak. The CMCP7504 does not provide -24VDC power to the eddy probe system.

The (TP) Thrust Position (Axial Position) Module is for connecting to eddy current probe system (also
referred to as a proximity probe system) with a mV/mil or mV/mm output. The signal is processed
for continuous monitoring and the overall amplitude is then converted into a 4-20mA output for
transfer to a PLC, DCS or other facility control system. Thrust Position can be displayed in terms of
millimeters (mm) or microns (um). The CMCP7504 does not provide -24VDC power to the eddy
probe system.
The (AM) Analog Input Module is for connecting an analog signal (4-20mA or 1-5VDC). The signal is
processed for continuous monitoring and the overall amplitude is then converted to a 4-20mA
output for transfer to a PLC, DCS or other facility control system. Analog Inputs can be displayed in
the user choice of terms.
The (TM) Temperature Input Module is for connecting either a 100 Ohm Platinum RTD or, most
commonly, a 10mV/°C signal from a dual output accelerometer such as STI’s CMCP786T or
CMCP785T. The signal is processed for continuous monitoring and the overall amplitude is then
converted to a 4-20mA, proportional to the full-scale range selected, for transfer to a PLC, DCS or
other facility control system. Temperature inputs can be displayed in terms of °C or °F.
The (XX) Empty Input Module is for when an input module is left empty, allowing the user to order
the system as a 1, 2 or 3 channel monitoring system.
Additional System Features
Relays and Alarms
The CMCP7504 Machine Protection System is designed to comply with the API 670 standard and offers
machine protection functions. The CMCP7504 provides 2 relay contact outputs, 1 for alert and 1 for
danger, for each channel. A global System OK relay is also provided. Local alarm status for each channel is
also provided on the bar graph display.
Buffered Outputs
For each channel, the sensor’s raw signal is available as a buffered output. Buffered outputs for each
channel are available at the BNC connector, located on the front cover, and at the terminal strip on the
main board. These buffered outputs are commonly used to connect portable data collectors or
permanently installed analysis devices in parallel to the CMCP7504 for FFT diagnostics.
Analog Outputs
The CMCP7504 provides a 4-20mA output for each channel. The 4-20mA output is proportional to the
full-scale range selected on the input module.
Modbus Output
A two wire Modbus 485 (half duplex) output is available on the internal terminal strips. The CMCP7504
can be configured to act as a slave device to allow the overall values to be sent over Modbus 485.
Configuration Utility
The configuration of each channel’s processing parameters (for example the measurement units or alarm
setpoints) is performed using a simple configuration software called the MMS Manager. The MMS
Manager can be installed on a Windows operating system (2000 or newer) and connects to the
CMCP7504 using a generic USB cable which is supplied with the system.

Function and Parts Description
1. Display Module
The display module shows the overall value, bar graph, user defined alert and danger setpoints,
point name and sensor status for each channel.
2. Push Buttons
A push button keypad is used to reset the relays for each channel. To reset, simply highlight the
channel needed and click OK.
3. BNC Buffered Outputs
For each channel, the sensor’s raw signal is available as a buffered output at the front panel BNC
connector. The BNC connectors may be used to connect a portable data collector for further
signal diagnostics.
Input Module Characteristics
The CMCP7504 supports accelerometers, velocity transducers, eddy current probes (proximity probes)
and all voltage or current outputs sensors. Once processed, the data can then be used for continuous
monitoring and overall value transmission to a PLC, DCS or other control system. The table below shows
the standard processing parameters. When available, the frequency can be set using a jumper on each
input module. The frequency range is not selected using the MMS Manager.
