2. Applications
The CIM 3XX BACnet module
(CIM = Communication Interface Module), which is a
BACnet master, enables data transmission between
a BACnet MS/TP (Master-Slave/Token Passing)
network and a Grundfos product.
The CIM 3XX is fitted in the product to be
communicated with, or in a CIU 3XX unit
(CIU = Communication Interface Unit).
Retrofitting of the CIM 3XX is described in the
installation and operating instructions of the
Grundfos product.
Further information
For further information about the configuration and
functionality of the CIM 3XX, see the specific functional
profile on the CD-ROM supplied with the product.

3. Installation
3.1 Connecting the BACnet module
A screened, twisted-pair cable must be used.
Recommended connection
Fitting the cable
Procedure:
See fig. 3.
1. Connect the red conductor(s) to terminal Plus
(pos. 1).
2. Connect the green conductor(s) to terminal
Minus (pos. 2).
3. Connect the grey conductor(s) to terminal
Ground (pos. 3).
4. Secure the cable with the earth clamp (pos. 4).
Earthing of the cable screen (optional) can be
obtained by connecting the screen to the earth
clamp.
Maximum cable length, see section 3.2 Termination
resistor.
Fig. 2 Example of BACnet MS/TP segment
Several BACnet masters may be connected to the
same BACnet MS/TP segment.
Fig. 3 Example of BACnet connection
3.2 Termination resistor
The termination resistor is fitted on the CIM 3XX
BACnet module and has a value of 120 .
The CIM 3XX has a DIP switch with two switches
(SW1 and SW2) for cutting the termination resistor in
and out. Figure 4 shows the DIP switches in cut-out
state.

out

Warning
The CIM 3XX must only be connected to
SELV or SELV-E circuits.

code Data signal
Plus Red Positive
Minus Green Negative
Ground Grey Ground
Note
According to the ANSI/ASHRAE BACnet
standard, the cable screen must only be
earthed at one end of the segment to
ensure correct operation and to prevent
earth fault currents.

Cable length
The maximum recommended cable length within
a BACnet MS/TP segment is 1200 metres (4000 ft)
with 0.82 mm2 (AWG 18) cable.
The connection between the BACnet modules must
be made by use of a screened, twisted-pair cable
with a characteristic impedance between 100 and
130 .
3.3 Setting the BACnet MAC address
The CIM 3XX BACnet module has two hexadecimal
rotary switches for setting the BACnet MAC address.
The two switches are used for setting the four most
significant bits (SW6) and the four least significant
bits (SW7), respectively. See fig. 5.
Fig. 5 BACnet MAC address
The table below shows examples of BACnet MAC
address settings.
For a complete overview of BACnet MAC addresses,
see the table on page 81.
3.4 Setting the Device Object instance
number
By default, the CIM 3XX BACnet module uses a
predefined Device Object instance number, which is
227XXX (XXX is the BACnet MAC address).
To use the complete Device Object instance number
range, set SW3 to ON, and set the new Device
Object instance number via a BACnet object in the
software. See fig. 6 and the specific functional
profile.
Fig. 6 Device Object instance number
DIP switch settings
3.5 Setting the BACnet transmission speed
The transmission speed must be set correctly before
the CIM 3XX BACnet module is ready to
communicate with the BACnet network. See fig. 7.
Fig. 7 BACnet transmission speed
DIP switch settings
Note
To ensure a stable and reliable
communication, it is important that only the
termination resistor of the first and last unit
in the BACnet MS/TP segment is cut in.
See fig. 2.
Note
BACnet MS/TP segments must be
provided with at least one set, and no
more than two sets of network bias
resistors. See fig. 2.
The network bias resistors are not
available on the CIM 3XX BACnet module.

4. LEDs
The CIM 3XX BACnet module has two LEDs.
See fig. 1.
• Red/green status LED (LED1) for BACnet
communication
• Red/green status LED (LED2) for internal
communication between the CIM 3XX and
the Grundfos product.
LED1
LED2
Status Description
Off. No BACnet communication.
Flashing green. BACnet communication active.
Flashing red. Fault in the BACnet
communication.
Permanently
red. Fault in the CIM 3XX BACnet
configuration.
Status Description
Off. The CIM 3XX has been switched
off.
Flashing red. No internal communication
between the CIM 3XX and
the Grundfos product.
Permanently
red. The CIM 3XX does not support
the Grundfos product connected.
Permanently
green.
Internal communication between
the CIM 3XX and the Grundfos
product is OK.
Note
During start-up, it may take up to
5 seconds to update the LED2 status.
