WIRING AND COMMISSIONING INFORMATION FOR

SATCHWELL MICRONET MN650

CONTROLLERS

APPLICATION

Satchwell MicroNet MN650 Series Controllers are fully-programmable

controllers designed for roof top, unit ventilator, air handling unit (AHU)

and zone heating and cooling applications. These controllers feature

universalinputs (UIs),digital inputs(DIs),triac outputsfor24Vac loads,

analogue outputs (AOs) and support for one MN-Sx digital sensor. The

MN650 controller operates from an external 24Vac or 24Vdc supply.

By setting the controller’s jumper pins, any of the universal inputs may

be configured as an analogue, resistive, or dry (volt free) contact input.

MN650 controllers can operate standalone or be networked in a

MicroNet ARCNET®network or a Native Communications Protocol

(NCP) network. For any model of controller, a PC with VisiSat™

Configuration Tool software is necessary to download and modify

applications.

An optional Real-Time Clock card can be fitted, which maintains

controller time during a power failure. The RTC card contains a 3V,

125mAh Lithium cell which has a life of at least 5 years.

Networked controllers receive time updates automatically from a

MicroNet Manager Interface or Touch Screen time master.

A Satchwell MicroNet Touch Screen or LCD can be mounted onto the

controller, which allows a user to view and modify controller properties.

Please refer to the Touch Screen Engineering Data Sheet (DS

10.050A) or to the LCD Engineering Data Sheet (DS 10.060A).

The controller also features an onboard power capacitor, to preserve

RAM for a maximum of seven days.

Wiring Routing Rules

The following table shows cable types that can be routed together:

Cable Screens

Earth each screen, but at only one end of the cable network, preferably

at the GND terminal (14) of an MN50-MI-NCP/ARC. If earthing a

screen at an MN650 controller, connect to terminal 40 (GND). Keep

wires emerging from screened cable as short as possible (and not

more than 150mm).

Note:Satisfactory NCP or ARCNET communications relieson the LAN

REF potential varying no more than 12V between any two devices in

the network (e.g. between an MN50-MI-NCP/ARC and any controller,

or between any two controllers). If this is not the case, introduce NCP

repeaters or ARCNET routers and connect the network as given in the

MicroNet System Engineering Guide.

Network Wiring

Introduction

Network wiring includes a connection between the controller and a

MicroNet controller network. Depending on the specific controller

model, one of two network types can be used:

•NCP network

•ARCNET network

Note that termination of cable screens can be critical to performance,

particularly in an ARCNET network. Network wire pairs must be

dedicated to MicroNet network communications. They cannot be part

of an active, bundled telephone trunk. If network cable is installed in

areas of high RFI/EMI, the cable must be in conduit.

Refer to the MicroNet System Engineering Guide for further guidance,

including network topologies, wiring, network lengths, termination,

screening and cable types.

NCP Network Wiring

MN650-NCP VARIANT

Controllers may be networked to either a 'main LAN' under an

MN50-MI-NCP or to a 'sub-LAN' under a MicroNet Touch Screen.

Recommended cable for NCP networks is Belden 9502 dual

twisted-pair screened cable for full opto-isolation in areas of high

electrical noise. However, Belden 8762 (single twisted pair cable) can

be used providing that the wiring precautions shown in the MicroNet

System Engineering Guide are followed.

Theterminals touse fornetwork connections dependon whetheror not

a Touch Screen is mounted on the controller.

1. Review the Precautions section.

2. If applicable, fit or remove two links as shown in the following

3. Connect the network to the controller, as shown in the following

diagrams. Observing correct polarity, connect one pair of the

dual twisted pair to the LAN and connect both wires of the other

pair to one of the LAN isolated (LAN REF) reference terminal(s).

Note: Connect the controller with other NCP devices in a

device-to-device fashion. Do not use wiring trees or stubs.

4. Ground the NCP wiring screen at one end of the cable only, e.g.

at the earth terminal of an MN50-MI-NCP. Mounting a MicroNet

Touch Screen in the controller causes the controller to be on a

sub-LAN of the Touch Screen. If required, continue the MicroNet

sub-LAN from pins 32, 33 and 71 or 72. The main LAN must connect

to pins 30, 31 and 69 or 70.

MN650-XCOM VARIANT

The MN-XCOM variant allows a local MN50-LCD to be connected to

the LAN B at pins 32 and 33.

ARCNET Network Wiring

Controllers may be networked to either a 'main LAN' under an

MN50-MI-ARC or to a 'sub-LAN' under an ARCNET router

(MN50-MI-RTR).

For performance reasons, when transferring network variables

between controllers and Touch Screens, the main LAN should have

only ARCNET routers connected to it, unless there are no sub-LANs.

Recommended cable for ARCNET networks is Belden 9502 dual

twisted-pair screened cable.

1. Review the Precautions section.

2. Ensure both links from the daughter board header are removed.

3. Connect the network to the controller, as shown in the following

diagrams. Observing correct polarity, connect one pair of the

dual twisted pair to the LAN and connect both wires of the other

pair to one of the LAN isolated (LAN REF) reference terminal(s).

4. Connect the controller with other ARCNET devices in a

device-to-device fashion. Do not use wiring trees or stubs.

5. Ground the ARCNET wiring screen at one end of the cable only,

e.g. at the earth terminal of an MN50-MI-ARC.

Thedevices at each end of the network must be biased and terminated

by fitting jumpers to A, B and C of LK4. If the controller is not at one

end, leave the links unset.

A local MN50-LCD can be connected to the controller at pins 32, 33

and 71 or 72 (LAN B):

no difference.

See the MN-Sx data sheet (DS 10.000A) for sensor connection

details.

Universal Input (UI) Wiring

UI Configuration

Each UI must be configured as either a Voltage (0 to 10Vdc),

Resistive/Temperature (0-10kΩ), or Digital Input. This must match the

usage of the UI in the controller application. Configuration is achieved

by placing the shorting block (jumper) onto the appropriate pins:

Refer to the controller’s 'Controller Definition Drawing' in VisiSat for a

picture of the required UI jumper settings for the controller. Factory

default configuration is shown in the following table. If an input is not

used, leave jumper in the default position.

Note: Each device connected to a UI must use a separate signal and

return conductor. If screened cable is used, connect the screen to

ground at one end only.

Voltage UIs

Note: An externally powered 0 to 10Vdc sensor is required. The input

impedance of a voltage input is 430kΩ.

1. Review the Precautions section.

2. Connect positive signal wire from 0 to 10Vdc device to desired

input terminal (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28 or 29).

3. Connect negative signal wire to one UI common (COM ) terminal

(57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68).

4. Make certain jumper is in Voltage position.

Resistive (Temperature) UIs

network wiring between controller and other devices is installed

according to job wiring diagram and national and local electrical

codes.

2. If operated from a 24V supply, verify that 24Vac power is provided

from a power transformer conforming to EN 61558 and wiring is

installed according to job wiring diagrams and with national and

local electrical codes.

3. Verify input jumpers are in correct position.

4. Verify outputs are wired according to job wiring diagram and with

national and local electrical codes.

5. Make certain current requirements of the controlled device do not

exceed rating of controller’s digital outputs.

Setting the Address of an NCP/ARCNET Controller

Each controller or other device on the same NCP or ARCNET LAN

needsa uniquenode address. The nodeaddress oftwocontrollerscan

bethe same if they are on different LANs; that is, separated bya Touch

Screen (NCP networks) or router (ARCNET networks).

Set the node address using switches 1 to 7 in bit switch S1. Do this

before powering up and cold starting the controller.

NCP/ARCNET CONTROLLER ADDRESS

Example: Placing switches 1, 3 and 6 in the ON position and switches

2, 4, 5 and 7 in the OFF position sets controller address to 37:

Although the controller’s address is set using the switches, the

controller’s address is activated only after the controller is cold or warm

started, as described on page 8. If the address has not been activated,

you will not be able to connect to the controller from VisiSat.

Cold and Warm Starting the Controller

Cold Start

Caution: If the controller’s Configuration Locked property has not

been set to Yes in VisiSat, the cold start procedure clears all

configuration data from the non-volatile EEPROM of the

controller. This means the control application will be erased.

A cold start is normally performed only once when controller is first

installed and before the controller application is downloaded. A cold

start results in all controller outputs OFF until an application is

downloaded. The cold start is performed using the controller’s switch

S1.

To perform a cold start:

1. Verify all devices connected to controller are in a manually

controlled safe state.

2. Energize controller and verify the following:

•Green ’Heartbeat’ LED (LD5) is steady on for a short period.

•After steady on period, the green LED adopts a normal

'heartbeat' flash rate.

3. Place bit switch 8 in ON position and then return to OFF position.

(green LED will flash rapidly for several seconds and then return to

normal 'heartbeat' rate.)

Notes:

1. Refer to ’Diagnostics LEDs’ section if required.

2. An online controller can also be cold started from VisiSat using

Force Defaults in the controller’s System object in Bubbleland.

Warm Start

A warm start resets the controller and causes any change of address

to be activated. When the controller is warm started, all

EEPROM-resident values are retained. However, controller outputs

cannot be guaranteed to stay at their present state.

To perform a warm start:

1. Verify all devices connected to controller are in a manually

controlled safe state.

2. Do one of the following:

•Select the Force Reset option from the controller’s System

object in Bubbleland (the controller must be online).

•Cold start the controller with the controller’s Configuration

Locked property set to Yes.

•Switch the power to the device Off, then On again.

SERVICING

Components within the controllers cannot be field repaired. If there is

a problem with a controller, carry out the following procedure before

contacting your local sales office.

1. Make sure controllers are connected and communicating to

desired devices.

2. Check all sensors and controlled devices are properly connected

and responding correctly.

3. If controller is operating, make sure the correct application is

loaded by using the VisiSat Configuration Tool. For more

information, see the VisiSat Engineering Guide.

4. Cold start the device and reload its application.

5. Record precise hardware setup, indicating the following:

•Controller firmware version number.

•Information regarding the Version number and build number of

the VisiSat Configuration Tool (see 'About VisiSat' option in the

VisiSat Tool Help menu).

•A complete description of difficulties encountered.

•A description of the status of the diagnostic LEDs.
