CTC offers solutions for Relay and Protection that provide a visual display of
the machinery vibration values, and also allow a customer-defined input level to
trigger a relay and shut down equipment that is operating out-of-tolerance.
SCD111
The SCD111 Series system monitors a machine’s condition based on its level
of vibration. The system can be integrated into a circuit to shut down a machine
when preset vibration levels are reached. The system detects high vibration
energy sensed via the input accelerometers and actuates relays based on alert
and alarm set points. The system will indicate the instantaneous vibration levels
and relay status at each channel through the display meters. The system also
supplies outputs for Dynamic Vibration data (Waveforms) transmitted by the
accelerometers via the BNCs on the front of the enclosure. The waveforms are
obtained from the BNC jacks located on the front of the enclosure or wired from
screw terminals identified by “Sensor Output.”
The SCD111 Series system is contained within a standard fiberglass enclosure.
Mounting brackets are provided for wall-mounting the enclosure (wall anchoring
screws are not included).
Rated for NEMA 4X (IP66), the SCD111 Series can withstand harsh environments
including temperatures ranging from -58°F to 180°F (-50°C to 82°C). The box is
also resistant to hose-directed fluid and corrosion. A snap latch is installed on
the door allowing the box to be sealed from the elements when not in use.

Independent stainless steel mounting feet are included on the enclosure. Wall
anchoring screws are not included. Note: If you have purchased a SCD111 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 SCD111 Series enclosure is grounded to
earth ground.
A. Mounting to Earth Ground
When mounting SCD111 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.

B. Mounting to Non-Grounded Structure
When mounting the SCD111 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
1½ in. conduit fitting or cord grips (1 per channel), output wiring is routed through
a 1½ in. conduit fitting. 110 Vac is needed to power the unit through the terminal
on the right side of the enclosure. If inupt options are selected when ordering, a
½ in. conduit fitting is provided for AC power entry.

The input to the internal controller comes from the vibration transmitter. They
are built with a specific full-scale range and frequency band. The full-scale range
of the transmitters must be known for the controllers to display the correct
vibration value. The transmitter will not display any vibration energy present at
frequencies outside the filtering range. Refer to the user manual for your specific
CTC signal conditioner for instructions on calibration and operation.
Example: Full Scale 0 – 1.0 IPS, Frequency Band 10 – 1000 Hz
At 0 IPS, 0.00 V flows from the transmitter to the controller. At 0.50 IPS, 2.5 V flows
from the transmitter to the controller. At 1.0 IPS, 5.0 V flows from the transmitter
to the controller.
The monitoring channel provides two relay outputs. The system comes from the
factory with a specific vibration range in IPS or mm/s. This range must be known
to configure the relay set points. It is recommended that baseline and typical
alarm values of vibration are also known before setup is attempted. The relays
provided by the internal controller are highly configurable. Refer to the PD765
user manual for detailed programming instructions.
All of the following parameters can be adjusted:
• Relay Action – Automatic, Latching, Auto + Manual Reset, Latch with Clear
• Relay Operation – Set and Reset points (Hysteresis), On and Off time Delays
Example Setup 1:
A full-scale range of 0 – 1 IPS has been specified. The baseline vibration on the
machine to be monitored is 0.18 IPS-pk. Alarm and shutdown levels of vibration are
defined as 0.35 IPS-pk and 0.65 IPS-pk, respectively. Reset points are specified
as 0.30 IPS-pk and 0.60 IPS-pk. Using the provided PD765 Process Controller
manual, select the relay operation and action desired. For this example, we will
have LOC, Latching Operation with Clear relays. Then program “Set 1” as 0.35
and “Set 2” as 0.65, then program reset points, “rST 1” as 0.30 and “rST 2” as
0.60. After relays have been programmed, scaling must be set. For this example,
we will use a 0-5 V input with a 0-1 IPS display. Program “inP1” as 0.00, then
“diS1” as 0.00, then “inP2” as 5.00, then “diS2” as 1.00. This will create an input of
0.00 V, display of 0.00 IPS, and at an input of 5 V, 1.00 IPS will be displayed by the
meter. The system will now actuate the LOC Relay (Relay 1) when the vibration
level reaches 0.35 IPS-pk and another LOC Relay (Relay 2) when the vibration

16
level reaches 0.65 IPS-pk. To reset the LOC relays, the vibration level must fall
below the reset point of 0.60, then press the ACK for relay two. Once the vibration
level falls below 0.30, press the ACK to reset relay 1.
Analog Output
The analog 4-20mA signal represents the amount of vibration energy present
at each channel based on the internal transmitter’s full scale, i.e., a 12mA signal
from a 0 - 2.0 IPS transmitter represents a vibration level of 1.0 IPS.
Manual adjustment of the internal transmitters may be needed to obtain the
analog 4-20mA output upon installation. Refer to the CTC Signal Conditioner
user manual for specific instructions.
Note: CTC does not provide the wiring to obtain the 4-20mA signal.

If there is no sensor wired to the sensor input terminal, the corresponding
transmitter for that channel will not power on. This will cause the Output Display
to read low or negative values. Be sure to power the system on AFTER the sensor
has been connected.
If the display fails to output a value after power has been turned on and the sensor
has been wired, turn off the unit, wait several seconds, and reapply power. The
internal electronics require some time to ramp up and settle before they are fully
operational.
Intermittent Power Failure:
• Ensure that there is no other power source connected to the dynamic pins.
• Depending on where the dynamic pins being wired to/measured from, try
measuring the dynamic outputs with a standard multimeter to rule out other
equipment interference/failure.
• Is the problem present on both dynamic outputs (the BNC and the pins)? Test
them each individually with the other disconnected and ensure proper wiring. If
it is only occurring on one of them, it can be faulty wiring or something coming
unsoldered from the board due to stress. Also, make sure the ± of the dynamic
outputs are not shorted together during measurement.
• Is the SC300 unit configured to have IEPE power turned on? If the voltage does
not work when the dynamic output is zero, and everything else above is fine,
we could be looking at a faulty part. There may be a bad transistor or op-amp,
or some other part damage.
