2.4 System diagram
The system diagram gives an overview of how to connect the
CIM/CIU 110 to the Grundfos booster system that is to be
connected to a LON network.
CIM 110 solution
The CIM 110 is an add-on communication interface to be fitted
directly into the following products:
• Grundfos CU 352 Hydro MPC
• Grundfos CU 352 Control MPC
• Grundfos CU 323 Multi-B
• Grundfos Multi-E (MGE model H and later)
• MAGNA3 Twinpump in multipump mode
Requires a CIM110 module installed in the master pump.
In all cases, the booster system will supply power to the CIM 110
module. See example in fig. 1.
The Hydro Multi-B controls and monitors a number of pumps (2 to
4).
CIU 110 solution
The CIU 110 is an external box with a power supply module and a
CIM 110 inside. It can be mounted on a DIN rail or on a wall. See
fig. 2.
Communication between the booster system and the CIU 110 is
established by use of an RS-485 cable. Please note that a
separate GENIbus module must be installed in the CU 351.
It is to be used with the products which do not support the CIM
module directly, namely:
• Grundfos CU 351 Hydro MPC
• Grundfos CU 351 Control MPC.
Fig. 1 CIM 110 solution for Hydro Multi-B and CU 352 MPC
Fig. 2 Example of CIU 110 solution with CU 351
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.

4. CIM 110 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.
Fig. 3 CIM 110 LON module
On Multi-E, you only need a CIM 110 in the master pump.
If there is a CIM 110 module in both pumps, write the control
commands to each pump.
A TPED model H is essentially a Multi-E model H with two pumps.
Mount a CIM 110 module in the master head.
MAGNA3 Twinpump in multipump mode requires a CIM 110
module installed in the master pump.
4.1 Connecting the LON module
We recommend using a cable according to Echelon standards.
Examples of recommended cable types
• Belden 85102
• Belden 8471
• Level IV, 22 AWG
• JY(St) Y 2 x 2 x 0.8
• TIA Category 5.
A LON network must be terminated. The termination depends on
the network topology chosen.
Fitting the cable
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).

4.2 Registration in a LON network
Controllers connected to a CIM/CIU 110 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/CIU 110 has two LEDs. See fig. 3.
• Yellow service LED (LED1)
• Red/green status LED (LED2) for internal communication
between the CIM/CIU 110 and the controller.
4.3.1 LED1
The yellow LED on the CIM/CIU 110 functions as a service LED.
When the controller 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 CIM/CIU 110.
When the CIM/CIU 110 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
CIM/CIU 110 in any way.
4.3.2 LED2
5. Considerations when installing the controller
To allow the CIM/CIU 110 to operate the Hydro MPC controller,
the controller must be set to operation via bus (control source
menu: settings/secondary functions/control source/controlled via
bus). The CIM/CIU 110 will read out values from the controller at
any time, but the controller will not be controlled until the control
source of the controller is set to "bus" via the operator display.
Some physical values have duplicate readouts, i.e. the process
values for discharge pressure (nvoDisPress, nvoDisPressF),
pump differential pressure (nvoPress, nvoPressF), external
pressure (nvoExtPressure, nvoExtPressureF) and flow (nvoFlow,
nvoFlowF).
These physical value pairs have a standard- and an extended-
range variable.
All the NVOs are active at all times. If the physical value in the
application is higher than the standard-range value, this will
saturate to its invalid value.
Example
For an application 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
NVO pair members to monitor.
Example
For an application with a maximum flow higher than 650 m3/h,
nvoFlowF should be used.
For an application 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 12. Details of the pump
controller's functional blocks.
For further details about the configuration, see the controller
documentation.
TM04 1958 1508TM04 2326 2308
Status Description

6. Selection of primary sensor
The controller can operate with different sensors used as the
primary sensor. The sensor feedback signal is used to control the
application in closed loop.
It is not all sensor types that are recognised by the CIM/CIU 110.
If the selected primary sensor is not recognised by the CIM/CIU
110, the CIM/CIU 110 will prevent the controller from operating
(the controller will be in STOP).
The types of primary sensor recognised by the CIM 110 are listed
in the table below.
The CIM/CIU 110 relates to the primary sensor in the following
way:
The primary sensor will be automatically detected by the CIM/CIU
110 without user intervention.
• nviPumpSetpoint (set in percent) will automatically be scaled
to the range of the primary sensor.
See section 12. Details of the pump controller's functional
blocks.
• nvoPumpCapacity (read out in percent) is the actual value of
the primary sensor scaled into its range.
See section 12. Details of the pump controller's functional
blocks.
7. Power-on behaviour
A Grundfos CIM 110 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 CIM 110 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 CIM 110 is switched off and on (power cycle), the actual NV
values in the CIM 110 will be lost and reset to their default values.
The NV default values can be found in section 12. Details of the
pump controller's functional blocks.
CP values are preserved in the CIM 110 over power cycles.
When switched on, the CIM 110 starts reading output values from
the controller (pressure, flow, etc.).
No other operation of the controller is applied until an update of
any of the following NVs is received via the LON network:
• nviPumpSetpoint
• nviPumpOpMode.
When an update is received, the CIM 110 will start operating the
controller.
The CIM 110 will poll the following NVs immediately after power-
on (if they are bound):
• nviPumpSetpoint
• nviPumpOpMode.
The CIM 110 will continue to poll these NVs with 10-second
intervals (if they are bound) until an update of any of the NVs is
received via the LON network.

11. Override functionality
The pump controller profile can override the setpoint. If
nviPumpOpMode is set to any of the values in fig. 9, the
nviPumpSetpoint will be overridden.
The controller will not return to normal setpoint control until the
nviPumpOpMode is set to HVAC_AUTO. The override priority can
be seen in fig. 9.
