Unit Description 4

4 Unit Description

The Computer Multi Control Top Concept Wireless
I/O-Unit is an "intelligent" enclosure monitoring sys­tem installed in its own housing mounted on the
enclosure. The enclosure monitoring system uses
the various connected sensors to perform the com­plete physical monitoring of the enclosure, namely,
temperature, humidity, access control and digital
input module. All this information is transferred using
SNMP to a management station where it can be
administered. The CMC-TC Wireless I/O-Unit can
also be used as a repeater. The direct connection of
the CMC-TC power pack starts this function.

4.1 Housing

The CMC-TC Wireless I/O-Unit is contained in its
own housing that can be fastened with the supplied
Velcro strips to the inner side of the side wall, to the
punched sections with mounting flanges or to the
shelf of the enclosure. Mounting units (see Section

4.5.1 "Required Accessories") can also be used to
install the housing.

6.1 Safety and Other Notes

− The Rittal CMC-TC system may be operated only
with connected protective earth conductor. The
protective earth conductor connection is made by
plugging in the IEC connection cable. This re­quires that the IEC connection cable at the power
supply side be connected with the protective
earth conductor.

− The electrical connection voltage and frequency
must conform to the rated values specified at the
rear of the housing and in the technical specifica­tions (see page 19).

− Before commencing work on the Rittal CMC-TC
system, it must be disconnected from the mains
power supply and protected against being re­connected.

− Protect the connection cables using cable ties on
the used housing or enclosure.

− To prevent unnecessary cable losses, the used
cable lengths must not exceed the lengths speci­fied in the technical specifications (see Chapter
14, page 19).

7.5 Tips and Notes for the Sensor
Placement

To prevent malfunctions and to ensure reliable op­eration, the sensors should be positioned as de­scribed in Subsection 7.5.1. Detailed fundamental
information for the used wireless technology is de­scribed in Subsection 7.5.2.

Before starting the measurement, all I/O-Units and
repeaters must be installalled and all antennas must
be aligned.

7.5.1 Tips for the Calibration of the Sen-

sor Locations

To ensure the best possible reception of the individ­ual sensors, the suitability of each sensor location
must be tested in advance using the wireless meas­uring system sensor (DK 7320.242).
Procedure:

i. Place the I/O-Unit into operation at the

planned location as described in Section

7.1.
Tip: Before starting the calibration, succes­sively connect all sensors to the I/O-Unit.
This causes the sensors to be placed in
front of the measuring system sensor in the
registration list of the Processing Unit II.
This simplifies the subsequent administra­tion.

ii. Connect the wireless measuring system

sensor to the I/O-Unit (see Section 7.2). To
do this, proceed as follows:
Place the I/O-Unit in programming mode
(press the C key for three seconds) > press
the key on the wireless sensor for five sec­onds (resets the sensor) > press the key on
the wireless sensor 1 second > the LED
flashes once briefly > sensor is registered >
leave programming mode of the I/O-Unit
(press the C key for two seconds, the wire­less connection LED on the I/O-Unit lights
up green).

iii. Place the sensor attachment bracket at the

required sensor location (true for all sensor
types). The sensor front side edge must
point later in the I/O-Unit direction.

iv. Place the measuring system sensor on the

attachment bracket. The sensor position
during the measurement must be the same
as the operation position.

v. Perform a one-minute measurement with

the measuring system sensor: Press the
key on the measuring system sensor >
the result of the previous measurement will
be displayed for five seconds > "1" flashes
in the display (indicates the one-minute
measurement) > if a different number is dis­played flashing, press the key several times
until the "1" appears > the measurement

EN

7 Commissioning

EN

starts after 5 seconds > the measurement
result (0-9) will be displayed after one min­ute.
(Details for the measurement and measur­ing times are contained in the operating in­structions of the wireless sensors.)

vi. Measurement result 8-9: The connection is

suitable for the productive operation. Re­move the measuring system sensor and
place the required sensor (temperature,
humidity, access or digital input) on the at­tachment bracket.

vii. Measurement result 0-7: Sensor location

not suitable. Change the position of the
sensor, use a repeater (see Chapter 9) or
use an external antenna. Then repeat the
measurement.

viii. Repeat steps iii. to vii. for each additional

sensor.

The wireless sensors now have an adequate con­nection to the I/O-Unit. This completes the installa­tion of the system.

If problems in the wireless area occur during the
installation of the system, Subsection 7.5.4 de­scribes the appropriate troubleshooting for correct­ing the fault.

Signal weakening
Even without obstacles, the sent wireless signal is

subject to a natural attenuation. The electric and
magnetic field strengths reduce by the factor 1/r
This means for distances exceeding approximately
1 m, the signal strength reduces by the factor 4
when the distance is doubled. Consequently, at
10 m distance from the transmitter, only 1/100 of the
signal strength compared with that at 1 m distance
will be received.

Any object through which the wireless signal needs
to penetrate causes an absorption of the signal (op­tical model: the light will be weaker). Whereas light­weight partition walls and doors cause only small
signal attenuation, masonry walls and coated glass,
persons or animals cause more signal attenuation;
metal causes large signal attenuation. Metal grids
act like metal walls.

7.5.2 Introduction to the Wireless Data
Transmission for the Rittal Wire­less Sensor Network

This section describes the principles of the associ­ated wireless technology that can be useful for set­ting up the wireless installation.

The sensor system operates with a frequency of

2.4 GHz. This means an optical consideration is

helpful for an initial planning for suitable installation
locations and distances.

The wireless signal is considered as being a light
beam with a dispersion characteristic appropriate for
light.
If you follow this model, it becomes clear that a di­rect line-of-sight connection between the base and
the sensor is the most favourable installation vari­ant. Walls, furnishings, etc., in the vicinity can, how­ever, act as a "mirror" that reflects the signal like
light. In this case, not only the original signal, but
also reflected signals from various directions arrive
at the receiving point. It is possible that the sent
data are incorrectly combined in the receiver. This
effect is called multi-path reception and can cause
major impairment of the reception quality.
This means even a line-of-sight connection between
the transmitter and the receiver is no guarantee for
a good connection.
