2. Introduction

2.1 About this functional profile

This functional profile describes the CIM 100 (LON

Communication Interface Module 100) and the CIU 100 (LON

Communication Interface Unit 100) for the following Grundfos E-

pumps and Hydro Multi-E:

• UPE Series 2000

• GRUNDFOS MAGNA/MAGNA3

• TPE Series 1000/2000

• CRE/CRNE/CRIE

•NBE

•NKE

•CHIE

•MTRE

•CUE

• Hydro Multi-E.

References in the following:

• The CIM 100 is referred to as "LON module".

• The CIU unit is referred to as "LON unit".

• The E-pumps, CUE, Hydro Multi-E, GRUNDFOS MAGNA and

MAGNA3 are referred to as "E-Pump".

The data in this document are subject to change without prior

notice. Grundfos cannot be held responsible for any problems

caused directly or indirectly by using information in this functional

profile.

2.2 Assumptions

This functional profile assumes that the reader is familiar with

commissioning and programming LON devices. The reader

should also have some basic knowledge of the anatomy of LON

data communication.

2.3 Definitions and abbreviations

2.4 System diagram

The system diagram gives an overview of how to connect the CIM

100/CIU 100 to the E-pump that is to be connected to a LON

network.

CIM 100

The CIM 100 solution is an add-on communication module that is

to be fitted in a Grundfos pump, using a 10-pin connection. In this

setup, the pump will supply power to the CIM 100. See fig. 1.

CIU 100

The CIU 100 solution is a box with a power supply module and a

CIM 100 LON module. It can either be mounted on a DIN rail or

on a wall. See fig. 2.

This solution is used for Grundfos Hydro Multi-E and E-pumps

that do not support an internal, add-on communication module

(CIM 100). The enclosure class is IP54.

Fig. 1 Example of CIM 100 solution

Fig. 2 Example of CIU 100 solution

Note

TPED twin-head pump based on MGE motor,

model H/I, in multipump mode requires a CIM 110

mounted in the master head.

3. Installation

The LON module is programmed on delivery. This means that the

application program will start when the power supply is switched

on.

The customer has to install the network, including assignment of

module addresses, and make the required bindings.

English (GB)

4. CIM 100 LON module

The LON module is designed using an FT 3150 neuron

transceiver, an FT-X1 transformer and a 64 Kbyte flash memory

which enables updating of software.

This functional profile is compliant with version 1.0 of "Pump

Controller Object" from LonMark International.

The LON module has been certified to adhere to LonMark

Application Layer interoperability guidelines 3.4.

Self-documentation strings are used. This means that an

installation tool can access the relevant information via the

network.

The XIF file can be found on the CD-ROM with this functional

profile.

4.1 Connecting the LON module

We recommend using a screened cable.

A LON network must be terminated. The termination depends on

the network topology chosen.

Fitting the cable

Procedure:

See fig. 4.

1. Connect the conductors to terminal A (pos. 1).

2. Connect the conductors to terminal B (pos. 2).

3. Connect the twisted screen ends to terminal "Screen" (pos. 3).

Note

The screen must only be connected to the screen

terminal of the CIM 100 LON module. See fig. 4,

pos. 3.

The cable screen must never be connected to

earth via the earth clamp. See fig. 4, pos. 4.

Note

The stripped part of the cable screen must be as

short as possible to reduce the impedance at

high frequencies.

4.2 Registration in a LON network

E-pumps with a CIM 100 LON module are registered by a LON

network in one of these ways:

• Service pin

• Bar code label.

Service pin

When the service pin push-button of the module is activated, the

module will send a unique 48 bit ID code (Neuron ID) which is

registered in the LON network. See fig. 5.

Fig. 5 Service pin

Bar code label

The Neuron ID on the module or on the enclosed bar code label is

scanned and registered in the LON network. The bar code of the

Neuron ID is in Code 128 format. The additional bar code label

can be attached to the building installation plan.

4.3 LEDs

The CIM 100 LON module has two LEDs. See fig. 3.

• Yellow service LED (LED1)

• Red/green status LED (LED2) for internal communication

between the CIM 100 and the E-pump.

4.3.1 LED1

The yellow LED on the CIM 100 functions as a service LED.

When the E-pump is connected to the power supply, the service

LED will flash once and then remain off if the installation has

been made correctly. In case of deviations, see section 17. Fault

finding and Echelon documentation.

The WINK command is supported by the LON module.

When the LON module receives a WINK command, the service

LED (LED1) will flash five times with 2-second intervals and a

duty cycle of 50 %. After five flashes, the service LED (LED1)

goes out. See fig. 6.

Fig. 6 Flashing pattern

This flashing pattern must not be confused with the flashing

pattern of an unconfigured device which will flash with 1-second

intervals and a duty cycle of 50 %.

In a standard installation, the service LED (LED1) is permanently

off.

The use of a WINK command does not affect the operation of the

LON module in any way.

4.3.2 LED2

TM04 1958 1508TM04 2326 2308

Status Description

Off. The CIM 100 has been switched off.

Flashing red. No internal communication between the

CIM 100 and the E-pump.

Permanently red. The CIM 100 does not support the

connected E-pump.

Permanently green. Internal communication between the

CIM 100, and the E-pump is OK.

5. Considerations when installing the E-pump or

Hydro Multi-E

Flow has duplicate readouts (nvoFlow, nvoFlowF). Both NVOs

are active at all times.

For an E-pump with a maximum flow higher than 650 m3/h, the

nvoFlow will display the invalid value (655.35 m3/h, 0xFFFF) for

pump flows above this limit.

At the time of installation, it should be determined which of the

flow NVOs to monitor.

For an E-pump with a maximum flow higher than 650 m3/h,

nvoFlowF should be used.

For an E-pump with a maximum flow lower than 650 m3/h,

nvoFlow should be used as it offers a higher resolution.

See description of the NVOs in section 11. Pump controller

functional block details.

For further details about the configuration, see the documentation

for the relevant E-pump.

English (GB)

6. Power-on behaviour

A Grundfos LON module is designed to run with the following

LON configuration:

• Node ID: 1

• Subnet ID: 1

• Domain ID: 00:00:00:00:00:00 (6 bytes).

The LON module will immediately start operating with these

settings on the LON network when the power supply is first

switched on. These settings can be changed with an installation

tool (not supplied by Grundfos).

If the LON module is switched off and on (power cycle), the actual

NV values in the LON module will be lost and reset to their default

values. The NV default values can be found in section 11. Pump

controller functional block details.

CP values are preserved in the LON module over power cycles.

When switched on, the LON module will apply control mode as

per the value of the CP nciControlMode. No other operation of the

E-pump is applied until an update of any of the following NVs is

received via the LON network:

• nviPumpSetpoint

• nviPumpOpMode

•nviOvdStop

•nviOvdPress

• nviOvdSpeed.

When an update is received, the LON module will start operating

the E-pump.

The LON module will poll the following NVs immediately after

power-on (if they are bound):

• nviPumpSetpoint

• nviPumpOpMode.

The LON module will continue to poll these NVs with 10-second

intervals (if they are bound) until an update of any of the following

NVs is received via the LON network:

• nviPumpSetpoint

• nviPumpOpMode

•nviOvdStop

•nviOvdPress

• nviOvdSpeed.
