This document contains information on the operation, installation and
maintenance of the SCE Series signal conditioner enclosure. This manual is an
overview of the system and references the specific component manuals. User
manuals are provided with the system for all configurable internal components.
Product Overview
The SCE Series signal conditioner enclosure is a turnkey solution coming fully
populated with signal conditioners, terminal blocks for sensor terminations,
and optional power supply. The signal conditioners are already pre-configured
based on the customer’s specific requirements. Terminal blocks are provided
for your sensor wiring terminations. These terminal blocks are pre-wired to
the signal conditioners and outputs from the signal conditioners are wired to
terminal blocks for integration into PLC/DCS systems. Each signal conditioner
utilizes screw terminals for the various input/output options such as, ±20 to 32
Vdc power input, ± signal output (1-2 configurable vibration outputs [0mA-20mA,
4mA-20mA, 0-5 Vdc, 0-10 Vdc] and a temperature output in 0.1-1.7 Vdc) and
± sensor input (vibration, displacement and temperature inputs). There is also a
green indicator light (Transducer Signal OK) which illuminates when the sensor is
properly connected to the transmitter and working correctly. The power supply
accepts input voltage of 100-240 Vac, 0.68A and 50-60 Hz; and provides 24 Vdc
to the signal conditioners and sensors. The power supply terminals include AC
Input Terminals (L) and (N), as well as Ground. DC Output Terminals are utilized in
providing power to the vibration transmitters. The output voltage of the power
supply is 21.6 – 26.4 Vdc.
Refer to the SC310 Series Signal Conditioner Product Manual for specific
electrical, performance, and calibration instructions.

Stainless steel mounting brackets are included on the enclosure. Wall anchoring
screws are not included. Note: If you have purchased a SCE400 Series enclosure
without cable entries provided, you should add your own entry prior to mounting
the enclosure. CTC does not recommend putting holes in the top of the enclosure
due to access and moisture concerns.

If you are running conduit to your enclosure, ensure the conduit cable entry is
located at the bottom of the enclosure when mounted.
Note: To ensure moisture will not flow into the enclosure, a hole should be drilled
at the lowest point in the conduit to provide drainage for any moisture.

Ensure the shield ground wire on the SCE400 Series enclosure is grounded to
earth ground.
A. Mounting to Earth Ground
When mounting SCE400 Series enclosures to earth ground (such as an I-Beam),
no additional steps are necessary, as the enclosure is grounded internally.

B. Mounting to Non-Grounded Structure
When mounting the SCE400 Series enclosure to a non-grounded structure,
ensure the shield ground wire or customer-supplied ground wire is tied to a
source of earth ground.

Cables enter and exit the enclosure through conduit fittings or cord grips on the
bottom of the unit. All input and output wiring is connected to the terminal blocks
and signal conditioners inside the unit. Inputs are routed through a conduit fitting
or cord grips (one per channel), output wiring is routed through a conduit fitting.
110 Vac is needed to power the unit through the terminal on the right side of the
enclosure. A ½ in. conduit fitting is provided for AC power entry.
Note: If utilizing cord grips for cable entry, ensure that all cord grip entries are
used, or that unused grips are plugged. Empty cord grips provide a path for
contaminates to leak into the enclosure and cause malfunctions.

Wiring Power
In order to supply power to the signal conditioners, CTC has an option for all SCE
enclosures to be equipped with a power supply and circuit breaker. Below is the

Wiring Inputs
Cables enter the enclosure through the designated entry option selected (cord
grips or conduit or custom user defined/installed options). All wires are connected
to terminal blocks within the enclosure. Sensor inputs for the SCE400 series are
located on the right side of the enclosure as indicated by the interior labeling
“Sensor Input.”

Note: 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.

Signal Conditioner Configuration
Refer to the SC310 and SC320 Series Signal Conditioner Product Manuals
for configuration specifications and procedure for SC310 and SC320 signal
conditioners.
Once all wires are connected, apply power to begin operating the signal
conditioner(s). Make sure the status light is indicating normal mode on each
SC300.
Operating Procedure
To operate the signal conditioners inside the enclosure, make sure that all wires
are properly connected, and then apply power.
Caution: Make sure that power input does not exceed specified limits or damage
to the system may result. See Table 1.
Calibration
Thesignalconditioneris calibrated internallyduringstartup. 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

18
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. 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
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 one-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 one-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

19
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.
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.
