2. Product Outline

2.1 Outline and features

The LM ADAPTER is a communication interface to connect the Mitsubishi Electric made products for M-NET

use with the LONWORKS network. Only one LM ADAPTER can control and monitor indoor units up to 50

sets.

Since the LONWORKS network is an open protocol, connection with the Building management system

(BMS) and other products usable with LONWORKS can be performed easily thus allowing construction of

various systems including "Schedule operation," "Interlocked operation" and "Energy saving control".

- Maximum 50 sets indoor units connectable with one LM ADAPTER

- Operation/monitoring with local remote controllers

- Standard Network Variables Type (SNVT) and enriched function (network variables)

- Various Configuration Properties (CP) essential for network construction

4.3 Selecting the system control parts

rang

Using the system controller (SC) together other than LM ADAPTER allows connecting operation. Some

rules to be observed for this purpose are introduced below.

4.3.1 Master controller and slave controller When LM ADAPTER is used together with other system controller inside a system under own control, it is

essential to set a slave SC(requiring a DIP-SW change). In this case, set it so that the control range of LM

ADAPTER is included within the control range of the system controller (air conditioner) which is to be the

master SC.

4.3.2 Local remote controller

The local remote controller includes ME remote controller (PAR-F27MEA, etc.) to be connected to the

M-NET indoor-outdoor transmission line of air conditioners and MA remote controller (PAR-20MAA, etc.) to be

connected to each indoor unit. Each remote controller provides a different function usable by LM ADAPTER

and a different system construction method.

(2) Caution on a system without using remote controller The following problems will be incurred when the operation/monitoring is done only from the BMS

(centralized monitoring system) without using the local remote controller. Therefore, please be sure to install a

local remote controller or system controller without fail.

① Test run can not be applied to air conditioners until the BMS has started up. ② Air conditioners can not be operated or monitored when trouble is generated on the BMS and

LM ADAPTER.

③ The detail of the trouble i.e. the stopping of indoor units can not be clarified. ④ The operation/setting of the items other than that controlled by the BMS cannot be performed. ⑤ Interlocked setting of LOSSNAY and air conditioners can not be performed.

Applicable to some model of CITY MULTI air conditioners ( manufactured after January 2003 ) even when using ME remote controller.

Applicable when only using ME remote controller for the standard models except the medium temperature models.

4.3.3 External contact input/output

The external contact input/output function is not provided to LM ADAPTER.

4.3.4 Power supply to M-NET transmission line The M-NET centralized system controller line should be powered. For the system using other system

controller or that with LOSSNAY only, the power supply unit for transmission line is required. In accordance

with the system configuration, the setting of LM ADAPTER and outdoor units should partially be changed.

Please conduct the setting operation by referring to the "Installation Manual" of LM ADAPTER. For the power

supply capacity of the power supply unit and the selection of the unit, please refer to the manuals (like DATA

BOOK) of each air conditioner.

4.5 Restrictions on system configuration

The restrictions in constructing the system by LM ADAPTER are outlined here.

4.5.1 Restrictions by system configuration

controller, the operation from the BMS is performed as follows.

4.5.2 Restrictions by control items

(1) Operation prohibit ① When using together the system controller that can set to prohibit the local remote controller operation,

make the controller for setting of operation prohibit one unit, either LM ADAPTER (BMS) or the system

controller.

② Operation prohibit can not be applied to other system controllers by LM ADAPTER (from BMS) ③ Although

they can be operated by LM ADAPTER (BMS) or other system controllers.

air conditioners can not be operated by the local remote controller of which operation is being prohibited,

At the unit of lowest address in the same group

(2) Emergency stop The emergency stopping of LM ADAPTER stops all air conditioners together, however it does not set the

operation prohibit of the local remote controller allowing the operation from other system controller or local

remote controller. To prohibit operation from the local remote controller, therefore, set it by entering

[Request Collective Local Prohibit] (collective).

*Operating to run during emergency stopping only results in immediate stopping.

(3) Operation mode In the case of cooling/heating selectable models of CITY MULTI, the operation mode will be determined by

the principle of the "Priority for former pressing." Under the circumstance, a same command should be

issued to all indoor units within a same refrigerant system to change the operation mode.

5. Design and Operation of LONWORKS System

This section introduces the mechanism, function and operating method of LM ADAPTER in configuring the

system of LONWORKS network by LM ADAPTER. As the operating method shown here represents just one

of the examples, you are kindly requested to carry out your designing to meet the system configuration or

operation in the actual system.

5-1 Constructing the LONWORKS network

The flow of installation procedure for LONWORKS network is shown below.

Step 1: Addressing (to determine the address of each node)

Step 2: Binding (to connect network variables)

Step 3: Configuration (for optimum service of each connection, adjustment of

re-transmission frequency and interval)

(1) Addressing An address is assigned to each node (equipment applicable to LONWORKS) on the LONWORKS network.

Set this address by using the install tool. Setting by using LM ADAPTER is not necessary.

(2) Binding The network variables between each node should be related with the exclusive tool like LonMaker for

Windows ® or the like.

(3) Configuration For the configuration property of LM ADAPTER, the initial value was set at factory shipment. The set value

may be changed depending on the configuration or operation of the network.

BMS Indoor [1]

Binding of network variables

5.2 Function relating to installing

(1) Service pin (Service switch) The service pin is used at the installation of LONW ORKS network.

Pressing the service pin sends out the service pin-message (control message including Neuron ID and

Program ID) to the network.

(2) Service LED The service ID indicates the present state of the product.

In the case of LM ADAPTER under the shipment state (Non-configured state), the service LED is blinking.

(3) WINK Upon receipt of the WINK message from the LONWORKS network, LM ADAPTER blinks the maintenance

LED 001 for about 10 seconds.

(4) Commission After completing the binding, the set detail is reflected on the node. Doing this way allows communication

between the nodes on the LONWORKS network.

(5) XIF To design the LONWORKS network, the configuration information of each node, interface (network

variables), etc. are required. When the product is already in your hand, such information can be obtained from

the LONWORKS network. Without the product, however, you may get it from XIF (eXternal Interface File)

locating the interface information of the product.

5.3 Operation at power recovery

5.3.1 Outline of LM ADAPTER operation After the power source is applied (the same as the power recovery after instantaneous power stop/power

failure), LM ADAPTER requires a time for initialization to collect the connection and operation state of air

conditioners up to 50 sets to be controlled. As the operation timing differs depending on the setting of

configuration property, you are kindly requested to carry out designing to meet the system operation.
