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 420mA 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.

Configuration Software Overview (MMS Manager)
The MMS Manager software, provided on a USB stick, allows the user to configure the following
parameters;
• COM Port Setting for RS232 Communications
• Transferring or Downloading the CMCP7504 Configuration File
• Measurement Point Name
• Input Signal Selection
• Engineering Unit Selection
• Alarm and Danger Alarm Limits
• Alarm Operation (Latching or Non-Latching)
• Alarm Time Delay
• Full Scale (Min/Max) Range
• Bar graph View Scale
• 4-20mA Output Scaling
• 4-20mA Offset
The screenshots below will show how the MMS Software Manager is used to program the CMCP7504.
Measurement Point Name
The user can input any “Point Name” desired through abbreviations or full words, however, spacing is
limited to 12 characters.
Input Signal Type
The input signal type is determined by the input module type. Verify the setup screen is programmed in
the same order as the input modules are installed on the main board.

Engineering Units
The engineering units drop down box allows the user to set the desired units in English or Metric. The
selected units should be set according to the layout of the sensor input modules.
Alarm Level Setup and Relay State
This section allows the user to set both the Alert and Danger setpoints along with the time delay and relay
operation.
Relay Operating Type
When the relays are set to non-latching, the relays will automatically clear once the amplitude drops
below the programmed threshold. When the relays are set to latching, the relays will hold their state until
the reset button is depressed.

Bypass
When the relays are set to bypass, the relays will not change state when an alarm threshold is reached.
Relay NE/NDE
When set to NE, the relays are normally energized (relay opens on alarm). When set to NDE, the relays
are normally de-energized (relay closes on alarm)
Relay Delay Time (ms)
A time delay of 0 to 10,000 milliseconds (ms) can be added to each alarm
Signal Scaling
The Signal Scaling section is used to set the CMCP7504’s analog outputs to match the configuration of the
sensor input module and display. The Full Scale Min and Full Scale Max should be set according to the
range selected on the sensor input module, for example, if the input module is set for a 0 to 2.00 in/sec
range the Signal Full Scale Max should be set for 2.00 and Signal Full Scale Min to 0.00.

View Scale
The View Scale is used to adjust the CMCP7504’s bar-graph display. The View Scale should match the
sensor input modules range or it can be set to display over-range readings as well.
4-20mA Offset
The 4-20mA offset is calibrated by the factory at the time of shipment and should not be changed unless
advised by the factory.

After all measurement parameters have been selected, click “Send Set Ch1” and the parameters will be
uploaded to the CMCP7504. Click the remaining Send Set buttons for channels 2-4. If desired, a single
channel may be configured or changed. Verify that the CMCP7504 shows the current updates and
disconnect USB cable.
Saving the Configuration File (Save File)
Click “Save File” to store a copy of the configuration file on your local drive.
Uploading Configuration File (Load File)
If a local copy of the configuration file cannot be found, connect a USB cable to the CMCP7504 and click
“Load File”. A copy of the existing program on the CMCP7504 will be uploaded to your computer and can
be saved to your local drive.
Configuring the Modbus RS485 Output
The CMCP7504 provides a two wire (half duplex) Modbus RS485 output for connecting to a PLC, DCS,
SCADA or other system. The Modbus settings can be found in the MMS Manager. The default Baud Rate
is 9600 and the Default Slave ID Number is 1. The Modbus settings can be changed using the MMS
Manager. Multiple CMCP7504’s can be connected to the same RS485 line by changing the Slave ID
Number.
