3.1 Connecting the VX CMC III access sensor to the CMC III CAN bus sensor
For reasons of clarity, these operating instructions do not contain all information details, nor can they take into account every
conceivable case of installation, operation or repair. Technical modifications reserved. In case of doubt, the German text prevails.
CMC III CAN bus sensor 7030.100
Description:
The VX CMC III access sensor can be connected to the CMC III CAN bus sensors.
The access sensors can also be connected in series to form a monitoring line
(max. 5 sensors). It is important that each line of 1 – 5 sensors always terminates
with the supplied RJ12 jumper plug (RJ12 socket x2). The function of the sensor
is to monitor access. The sensor is assigned a code by which it is automatically
identified and set by the CMC III system. The sensor can be used if the following
components are available:
◾ CMC III Processing Unit (7030.000) or CMC III Processing Unit Compact
(7030.010) with power pack (e.g. 7030.060), country-specific connection
cable, programming cable.
◾ CMC III CAN bus sensor (7030.100), CAN bus connection cable
(e.g. 7030.090).
◾ Extension cable 7320.814 for connection to the CMC III CAN bus sensor and,
if necessary, for interconnection of the sensors, depending on the mounting
position.
The sensors contain an LED for indicating the status of the door
(LED on = door open/LED off = door closed).
Note: When the sensors are connected in series, with the door closed, the LEDs
will not be extinguished until all doors have been closed for the sensors
behind them, right through to the final sensor (sensor with jumper).

General conditions of use:
◾ The sensor may only be used together with the Rittal CMC III system.
◾ The operating instructions/safety instructions of the CMC III Processing Unit
and of the above sensor apply.
◾ The max. cable length between the CAN bus sensor and the first sensor is
2 m, the same applies between the sensors. For the connection you can use
the connection cable 0.5 m or the extension cable 7320.814, 2 x 1 m.
For special applications/lengths please contact our central office.
◾ The VX CMC III access sensor can also be connected to the DET AC III
extinguishing system. Please follow the instructions of the extinguishing system.
◾ It is absolutely imperative that these cables are installed separately from mains
power cables.
◾ The sensors may only be used in areas where the specified ambient conditions
apply.
◾ The sensor housing must not be opened. The unit does not contain any parts
that need servicing.
◾ Before connection, ensure that the sensor is suitable for the device/slot.
◾ Safety devices must not be deactivated.
◾ The sensor must not come into contact with water (e.g. dew), oil sludge or any
aggressive substances.
◾ The unit must not be operated in environments with flammable gases or
vapours. Protection from water, dust, etc. must be ensured by installation in an
enclosure or rack.
◾ The CMC III system must not be live with voltage when the sensor is being
connected to the CAN bus sensor.
Technical data:
◾ 2 x sensors with reed contact (mounted on enclosure frame)
◾ 2 x magnets (mounted on the moving part)
◾ 2 x jumper plug RJ12 to terminate the monitoring line
