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. In addition, the CMCP7504 also allows for a single temperature input and speed input for a tag readout on the display allowing for a total of 6 measurement points. The STI CMCP7504 can accept up to four signal processing modules. Various modules are available for different sensor and measurement types. Each input module can process the signal from one sensor and up to four modules can be installed in a CMCP7504. The available input modules are: AA ‐ Acceleration Module AV ‐ Velocity Module, Accelerometer Input VV ‐ Velocity Module, Velocity Sensor Input EV ‐ Enveloped Acceleration Module, Accelerometer Input SV – Velocity Module, Seismic Velocity Sensor 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.

AUX Temperature A single temperature input is provided on the CMCP7504 and does not require the use of an input module. The Auxiliary Temperature channel accepts a signal from a dual output accelerometer (10mV/°C) or a PT100 RTD to be connected to the system and the value displayed on the screen. Visual alarming is available if alarm limits are set. Visual alarming will change the color of the readout on the display when an alarm condition is met. Relay and analog outputs are not provided with this channel. AUX Speed A single speed input is provided on the CMCP7504 and does not require the use of an input module. The Auxiliary Speed channel accepts a signal from a 2 or 3 wire pulse output sensor and the value will be displayed on the screen. The number of events per revolution may also be programmed to allow for measuring equipment with more than 1 target. Modbus Output A Modbus TCP/IP output and RTU output are provided on the CMCP7504. See “Modbus Output” setup page. The Modbus output can be taken back to a control system for livestreaming data. DataView Overall Value Saver The DataView Overall Value Saver feature allows for recording of the overall value for each of the four channels. A removable internal SD card, with a 1 GB of memory, stores the overall values for each channel every minute. The data is saved as a .txt file and time stamped for retrieval at a later time if necessary. SignalSaver The SignalSaver feature records the sensor’s signal for 30 seconds when an alarm condition is met. The signal is saved on the removable internal SD card and is in a .wav file format. The .wav file can then be imported into a portable data collector, or online system, allowing for viewing of the time waveform and FFT. All files are timestamped and logged onto the SD card until cleared by the user. On average 1 year of data can be saved.
