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 [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 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 SCE200 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 SCE200 Series enclosure is grounded to
earth ground.
A. Mounting to Earth Ground
When mounting SCE200 Series enclosures to earth ground (such as an I-Beam),
no additional steps are necessary, as the enclosure is grounded internally.
Figure 5. Proper Shield Grounding Technique

B. Mounting to non-grounded structure
When mounting the SCE200 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 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
