This document contains information on the operation, installation, and
maintenance of the SC150 Series Signal Conditioner. The signal conditioner is
a device that converts a sensor input to a 4-20 mA output signal and provides
a buffered dynamic output of the vibration waveform. The signal conditioner
accepts input from a 100 mV/g accelerometer.
SC150 Series Overview
The SC150 signal conditioner is a DIN rail mountable component used in
continuous machinery monitoring applications. It provides signal conditioning,
signal conversion, and re-transmission. Limited settings are configured using
downloadable and easy to use software (requires PC and a micro USB cable).
User-programmable settings include:
• 0-5 V or 0-10 V output
• IEPE Power enabled or disabled
• Output scalable for Metric and English
General features include:
• Two buffered dynamic outputs, one via BNC and one via terminal blocks
• 35 mm DIN rail mountable
• Removable terminal blocks facilitate easy wiring
• Full scale range from 2 Hz to 1000 Hz on SC150-XX-XX-00
• Full scale range from 10 Hz to 1000 Hz on SC150-XX-XX-01
• LED indicator for unit operation and basic troubleshooting

Electrical Connections
1. Connect the +20 - 32 Vdc power lead to the terminal marked 5 and the negative
or common to the terminal marked 6.
2. For single-axis accelerometer input connection, wire the sensor leads to 13(+),
14(-), and 15(shield drain wire) as shown in Figure 1.
3. Connect the output device to terminals 11(+) and 12(-) for channel one’s
4-20 mA signal proportional to the vibration level. If measuring from a voltage
signal rather than a 4-20 mA loop, connect to terminals 7(+) and 8(-) instead.
4. Terminals 1, 2, 9, 10 and 16 are inactive.
5. The dynamic signal output can be obtained from the BNC connector at the top
of the signal conditioner or from terminals 3(+) and 4(+).

Terminal connections are also listed on the side of the signal conditioner.
Wiring for Biaxial/Triaxial Accelerometers
The SC150 Series signal conditioners are compatible with 100 mV/g biaxial and
triaxial sensors. Each vibration input will require a unique signal conditioner, so a
triaxial sensor will require three SC150 units, and each biaxial sensor will require
two SC150 units. Each axis of vibration will have its own signal conductor wire,
which will then be run to a separate SC150 on terminal 13. The black common
conductor will be run to one of the signal conditioners at terminal 14, then must
be daisy chained to terminal 14 of the remaining signal conditioners. For more
information or questions, please contact CTC.
Mounting
The signal conditioner is designed to be mounted on a 35 mm DIN rail. The
mounting clip is spring-loaded to facilitate simple permanent locating. To remove
the signal conditioner, use a small flathead screwdriver as a lever on the spring-
loaded mounting clip. With the clip disengaged, slide the signal conditioner from
the mounting rail.

Running the application
When you run the CTC Signal Conditioner Application, the first thing that will
appear is a device select screen. This is where all units currently plugged into the
computer will appear. If no signal conditioners are plugged in to the computer, a
pop up window will display requesting that one be connected. Note: It is currently
discouraged to plug multiple devices in at the same time due to a limitation of the
USB serial drivers that cause the devices to lock up if any two USB COM ports read
or write at the same time. If this occurs, unplugging the devices should resolve the
issue. From this window, if a signal conditioner is connected to the computer, it will
appear automatically in the list and will be selected as soon as it’s detected.
Clicking the Configure Your Signal Conditioner button on the left of the screen will
take you to the page in Figure 3.

Configuration Software
There are several different controls for changing the configuration of the selected
device. The Part Number text box will display the part number for the currently
selected configuration values. The Part Number text box will also change the
selected configuration values if a part number is typed or pasted into the box.
The Serial Number box will display the serial number of the currently selected
device.
The Device Type box will show whether the currently selected signal conditioner
is Single Channel or Dual Channel.
Figure 3. Signal Conditioner Conguration Window

12
The “IEPE Power” dropdown menu controls whether or not the built-in IEPE
supply on the device is enabled or disabled. In Figure 3, the IEPE power supply
is configured to “ENABLED,” so once configured and plugged in, the signal
conditioner will supply a constant 4 mA to the sensor. The sensor input and thus
settings described above are shared by both channels.
Once the desired configuration is set, the device will need to be programmed
by pressing the “Program Your Signal Conditioner” button. A new window will
pop up and show the current progress. If this process fails, be sure to read the
troubleshooting guide. The “Update Firmware” tab shown in Figure 4 is where the
user can update the signal conditioner’s firmware by clicking “Update Firmware.”
The Diagnostics tab, shown on the following page in Figure 5, is where device
errors and warnings can be read off the signal conditioner (see Indicators in the
Operation section) by clicking “View Errors.” If errors are present on the device,
View Errors will read them and display information about the error(s) for corrective
action. Any errors that appear may be cleared from the device by clicking “Clear
Errors.” Both operations are done via the USB port, like when programming the
device.

Accessing Configuration History
Clicking “File” in the top menu will allow the user to select an option to view
previous configurations. Selecting this option will open the computer’s default
text file viewer with a log containing the date, time, serial number, part number,
and full configuration.

Once all wires are connected, apply power to begin operating the signal
conditioner. Make sure the status light settles to normal mode.
Note: When the software reports an error, it does not necessarily mean that the
error is currently present on the signal conditioner. It just means that the error
has been encountered at some time and recorded for reporting. For example, if
the signal conditioner was powered before any output wiring was complete, the
device will record an output error. If wiring is then completed, the output error
will go away if the wiring is correct but would show up in an error report if not
cleared. Always reference the LED indicator for live device status, and remove
any erroneous/out-of-date errors.
Calibration
Thesignalconditioneriscalibratedinternallyduring startup.The digital calibration
eliminates the need for any adjustments to the analog output.
Indicators
The LED on the front of the signal conditioner will indicate the status of the signal
conditioner.
State 1 - Normal Operation
• LED is solid green
State 2 - Input Short Detected
• LED is rapidly flashing red
A short circuit is indicative of a lack of electrical resistance, removing the ability
to measure the impact from a change in voltage. This instance is largely driven
by an incorrect wiring setup. Verify that all wiring connections are attached in
the correct polarity, and that no signal and common wires are touching. Ensure
that the signal conditioner is configured with IEPE power ON if the sensor is not
being powered from any separate source. Lastly, ensure that the system is free
of water and other contaminants.
State 3 - Input Open Detected
• LED is solid red
An open circuit implies a physical disconnect somewhere on the electrical path

15
of the circuit. When receiving this error, verify that there is no physical separation
within the system, such as unattached or broken cabling. Be sure that the
connector is firmly secured to the accelerometer, and that the accelerometer is
in good working order.
State 4 - Device Warning Detected
• LED is flashing green in 1-second intervals
A detected warning can be due to several things, such as incorrect output wiring
(e.g., an open circuit detected on a current output or a short circuit detected
on a voltage output) or corrupted configuration memory. The device will still
be processing input data. However, it may be running in a reduced state or
return unexpected results (e.g., if memory is corrupted, the unit will default to
the standard ISO configuration until reprogrammed). If this state is detected,
carefully inspect all wiring for secure connections and cycle power to the device.
If the warning persists, the configurator can be used to determine the root cause
and corrective action.
State 5 - Fatal Error
• LED is flashing red in 1-second intervals
In the case of a fatal error, the device has detected some non-recoverable
hardware issue which could have been caused due to physical damage or misuse.
Processing will be disabled in this case. Communication with the configurator
may or may not work depending on the root cause but should be attempted as
it may state the error that occurred. In some cases, cycling power to the device
can remedy the issue.
State 6 - Programming and Startup
• LED is solid orange
This state occurs when the signal conditioner starts up, confirms there is an
available configuration, and sets up its peripherals and outputs. If the USB cable
is connected and plugged into a PC, this state will persist. Plugging in the USB
cable at any point will also cause the device to enter this state. Regular operation
will not occur while the USB cable is plugged in.

16
State 7 - Bootloader
• LED is flashing between red and green
This state occurs during device startup and indicates the bootloader is running.
This state will persist if new firmware is being written for the duration of the
update. If no firmware update handshake is received from the configurator within
5 seconds, the device leaves this state and continues with the startup.
Portable Data Collector Interfacing
When collecting waveform data from the BNC jack on the signal conditioner using
a portable data collector that supplies constant current power, it is recommended
that the data collector is configured so that power to the sensor is turned off.
Although the BNC connector circuitry offers short circuit protection and can
safely sink the current, long-term degradation may occur due to increased power
dissipation depending on the magnitude of the IEPE current. There is no need
for the data collector sensor power to be turned on for the data collection to be
made, and it is the safest way to make measurements if possible.

If the SC150 is correctly connected via USB and the software properly installed,
the serial number of the device will appear in the dropdown menu.
If a serial number doesn’t appear, follow the troubleshooting steps below.
• Check the USB connection to make sure it is secure.
• Confirm that the LED indicator on the SC150 unit is lit up with a solid orange
light (LED will blink when first plugged in and should then turn solid orange).
If both steps above are confirmed, then the device might be missing critical PC
drivers needed to read the USB.
In this case, navigate to the Device Manager program (through the Start menu on
Windows Devices) and look for the drop-down menu on the left side of the page.

18
Look for and select the “Other Devices” option, then right-click on “USB Serial
Port.” Select the “Update Driver” option.
Select “Search Automatically for Drivers,” and the computer should search for
and install the necessary driver.
If the driver updates correctly, there will no longer be a “USB Serial Port” option
in the “Other Devices” section, and a new option will appear in the “Ports” section
of the drop-down tree.
Once this is completed, open the CTC Signal Conditioner program. The SC150
will appear with a serial number, and all functions will perform correctly.

19
If a notification appears that there is no available upgrade, the driver will have to
be installed manually.
The first step is to go to the link below –
https://ftdichip.com/drivers/vcp-drivers/
Scroll down to the download link section and select the setup executable option
on the left side.
Save the file – it will be saved as CDMXXXX_Setup.
Retrieve the file from the Downloads section of your File Manager, and run the
program.

20
A standard installation wizard will open. Follow it to completion.
When this is complete, return to the Device Manager. If all is correct, USB Serial
Port (COMX) will be displayed in the Ports section of the drop-down menu.
When this appears, open the CTC Signal Conditioner program. The
SC300 will appear with a serial number, and all functions will perform
correctly. Please feel free to contact CTC for any technical assistance.
