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, power supply, and terminal blocks for
sensor terminations. 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 [0 mA-20 mA,
4 mA-20 mA, 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, .68 A & 50-60 Hz and provides 24 Vdc
to the signal conditioners and sensors. The power supply terminals include AC
Input Terminals (L) & (N), and 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.

Independant stainless steel mounting feet are included on the enclosure. Wall
anchoring screws are not included. Note: if you have purchased a SCE100 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
enters from 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 SCE100 Series enclosure is grounded to
earth ground.
A. Mounting to Earth Ground
When mounting SCE100 Series enclosures to earth ground (such as an I-Beam),
mount the shield ground wire using a mounting bolt through one of the mounting
brackets on the enclosure.
Figure 5. Proper Shield Grounding Technique

B. Mounting to non-grounded structure
When mounting the SCE100 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 (1 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 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 SCE100 series are
located on the right side of the enclosure as indicated by the interior labeling
“Sensor Input.”
