CTC modular MAXX box solutions allow for the monitoring of remotely mounted
vibration sensors, which would otherwise be restricted to human access due to
safety considerations.
MMX2000 Series Modular MAXX Box Overview: 3-12 Channel boxes, stainless
steel enclosure
The MMX2000 3-12 channel enclosure is a common cable termination point for
bringing in a variety of sensor applications including single axis, biaxial, triaxial,
and dual output (vib/temp) sensors for routine data collection with portable data
collectors.
The MMX2000 Series offers convenient three position quick connect terminal
blocks for terminating the sensor of your choice.
Setup of DIP Switches
In addition to the most popular application of single axis sensors the MMX-MOD3
modules can be setup to provide grouped signals from a Dual Output sensor,
triaxial or biaxial style sensor that share the “common” conductor. By adjusting
the dip switches, the common connection can be shared between inputs 1 & 2,
2 & 3, for dual outputs and between inputs 1 & 2 for biaxial sensors or 1, 2, & 3
for triaxial sensors. This eliminates the need to insert jumper wires between the
different inputs within the module. The switches are displayed further on in this
manual. Note: All modules are set at “Commons OPEN” at factory.

Note: if you have purchased a modular MAXX box without cable entries provided,
you should add your own entry prior to mounting the modular MAXX box. 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
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 MMX2000 Series Modular MAXX box is
grounded to earth ground.
A. Mounting to Earth Ground
When mounting MMX2000 Series Modular MAXX boxes 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

8
B. Mounting to non-grounded structure
When mounting the enclosure 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 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. Red insulated conductor wire is connected to (+).
b. Black insulated conductor wire is connected to (-).
c. Shield drain wire is connected to ground (GND).
d. Depress selected position button to open terminal for respective wire (may
require a mini at head screwdriver).

5. Insert plug into the appropriate PC board connector and double check to ensure
that the cable is going to the correct channel.
6. Mark the Measurement Location Card located on the inside front cover with a
description of each measurement location.

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 termination 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 to the modular MAXX 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 @ 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.
