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.

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.

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.

LED2

Status Description

Off. No BACnet communication.

Flashing green. BACnet communication active.

Flashing red. Fault in the BACnet

communication.
