CTC MAXX Box solutions allow for the monitoring of remotely mounted vibration
sensors, which would otherwise be restricted to human access due to safety
considerations.
MX333 Series MAXX Box Overview: Sixteen triaxial sensor inputs (48
measurement channel outputs), fiberglass enclosure
The MX333 is a fiberglass enclosure designed for data collection of up to 16
triaxial accelerometers. The MX333 provides connection of the four-conductor
input wiring for a maximum of 16 triaxial accelerometers for portable data
collection. Data is collected via four, four-pin output connectors compatible
with Azima DLI Data Collector Cables. Input wiring from the sensors is wired to
the outputs via terminal blocks located behind the hinged output panel. Inputs
available on each terminal block include positive and negative for each axis or
sensor signal, and one input for the shield drain wire that is grounded via an
external ground stud mounted to the side of the fiberglass enclosure.
All MX333 enclosures feature a hinged cover with a mounted snap latch to
protect each four-pin connector when not in use. Rated for NEMA 4X (IP66), the
box is resistant to hose-directed fluid and corrosion and is rated for temperatures
ranging from -58°F to 180°F (-50°C to 82°C).

Note: if you have purchased a MAXX Box without cable entries provided, you
should add your own entry prior to mounting the enclosure. CTC does not
recommend drilling 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 MX333 Series MAXX Boxes is grounded to
earth ground.
A. Mounting to Earth Ground
When mounting MX333 Series MAXX Boxes 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 termination box to a non-grounded structure, ensure the
shield ground wire or customer-supplied ground wire is tied to a source of earth
ground.

Installation of Sensors/Signal Input Cable
1. Feed blunt-cut end through the cable entry at the bottom of the enclosure.
Note: it is recommended that cables are marked on both ends.
For cord grip cable entry, take off the cord grip cover with bushing and run cable
into enclosure, hand-tighten cord grip cover to base to prevent damage of cord
grip.

1. Strip outer jacket of cable back 1¼ in. and remove all of the shielding.
2. Separate the internal wires from the shield and twist the shield.
3. Strip red and black insulation back ¼ in.

4. Locate the appropriate plug, identified by channel number, remove the plug and
install the wires using a small flathead screwdriver. Push plug back into location.
Orientation is as follows:
a. White insulated conductor wire (Z) is connected to the rst channel used.
b. Red insulated conductor wire (Y) is connected to the second channel used.
c. Green insulated conductor wire (X) is connected to the third channel used.
d. Black insulated conductor wire is connected to (-) common.
e. Shield drain wire is connected to ground (GND).

The TM1018 Accelerometer Verification Meter can be used to verify cable
conductivity, sensor location and proper wiring connections. The Verification
Meter will indicate if the sensor, cable and/or junction box is in working condition.
It will also confirm bias voltage of the accelerometer, which will inform you of the
operation of the internal accelerometer amplifier.
Testing Method:
1. Utilizing two personnel, Person A will be located at the MAXX Box, while Person
B will be located at the measurement location.
2. Once positioned, Person A will connect the TM1018 to the data collector
output on the termination box and turn the Channel Selector to the channel
that corresponds to the referenced measurement. Person A should observe a
“NORMAL” LED reading.
3. Person B disconnects the cable from the accelerometer, and the TM1018 should
respond with an “OPEN” LED. Reconnect the cable to the accelerometer, and
the TM1018 should respond with a “NORMAL” LED.
4. Repeat for each measurement location to verify that accelerometer location is
properly identified at the termination box.

The following LED Readout indicates the circuit integrity:
1. Green LED: Normal. Indicates proper connection and an output bias will be given,
indicating the health of the sensor (4 – 16 V indicates a healthy accelerometer).
2. Yellow LED: Open Circuit. Indicates one of the following:
a. Cable connector is not connected to accelerometer.
b. Cable is open circuit (broken or not connected at one end).
c. Accelerometer is not functioning correctly.
3. Red LED: Short Circuit. Indicates one of the following:
a. Water or contamination in the connector.
b. Reverse wiring ((+) and (-) leads are reversed).
c. Wires in termination box or cable connector (+) & (-) are touching.
