Description

The Neets 4 Relay box gives you up to 4 dry contact relays that each can be controlled by a control input1

(Supported by all Neets Control systems) or by RS-232. The relay box can be used in ether low voltage or

high voltage (230VAC) mode, and never at the same time(The applies for the Relay 1 and 2 when using the

“Screen” connector).

On each of the four relays you have access to both the NO (Normal open contacts) and the

NC (Normal close contacts). This gives you the opportunity to use it according to your

needs.

When using the Neets 4 relay box you have the benefit of selecting what type of voltage

you want to use at installation time.

The flexibility of the relay box offers you the possibility to control high voltage or low voltage (Please note

that high and low voltage cannot be used simultaneously).

Safe way to control a screen or lift

The relay box, offers you the possibility to link two relays together and thereby adding extra security when

controlling e.g. screen or projector lift.

When two relays are linked together only one of the relays can be “Set” at a time.

Furthermore, you can define the time from one of the linked relays is “Released” to it is possible to “Set” a

relay again, this time adds additional protection of the connected screen/lift motor.

When using this security feature, it is active whether you control the relay box by the 4 control inputs or by

RS-232.

Note that the relay box’s relay 1 and 2 from factory is configured to control a 230 VAC screen or lift. Using the “Screen” connector and there for you must not use the “Relay-1” and “Relay-2” connectors. If you do not want to use the “Screen” connector, please remove fuses F1 and F2 “Screen 5A”. Read the section “Controlling an electrical screen or lift” on page 7 for further details.

When 4 relays are not enough

The Neets relay box gives you the possibility to connect up to 4 boxes together on the same RS-232. When

doing this you get up to 16 relays that are all controllable individually by only one RS-232 port.

1 “Control inputs” is the name used in this manual for the 4 inputs that allows the Neets control system to control it directly.

Com

NCNO


All Neets control systems support up to 2 relay boxes on one RS-232 port as it is. If you want more than 2

relay boxes on a RS-232 port, you have to use an active splitter and connect it as shown on page 9.

How to connect it?

This section will explain how to connect the Neets Control – EU with the Relay box 306-0003. It will also

give some examples on how to connect an external device to the relay box. Please note that there are

several other ways to use the relay box than described in this guide.

ALWAYS be sure that 230 VAC is disconnected when installing/changing ANYTHING.

When you receive the relay box, relay 1 and 2 are already configured to run screen mode.

If you do not want to use the screen mode or control low voltage unites always remember to remove

fuses F1 and F2 (Screen 5A)

Connecting the Relay box to the control system.

Pin name Description

GND Ground RELAY-4 Control input for Relay 4. Relay is activated when

pin is connected to GND. RELAY-3 Control input for Relay 3. Relay is activated when



pin is connected to GND. PWR OUT 12 V Dc positive supply for the control system GND Ground RS-232 in RS-232 Receive data from control system (or PC

when testing or setting up the relay box) GND Ground

If you control the relay box with both its input controls and by RS-232, you have to be aware that if the

relay is activated by RS-232, you cannot release it with the input controls and vice versa.

When controlling the relay box from the Neets Control – EU system you can connect it like this:

306-0008-002-001 Rev500 Neets 4 relay

Controlling a electrical screen or lift

The relay box offers you easy connection of an electrical screen or lift.

By using the screen terminals you get an easy connection of your screen and even

more the high security mode prevent you from accidentally making short circuit.

The Relay 1(RELAY-1) is now controlling the screen in one direction, and there is ONLY power to the screens

other direction (RELAY-2) when Relay 1(RELAY-1) is “Released”. Be sure to set up the software to fit this

hardware configuration.

To enable the screen mode insert the fuses F1 and F2 (Screen 5A)


Cable in/out of the box

The relay box comes with rubber globs, that allow you to use any cable size you want, and the taps inside

the box gives you a good and flexible way of safely fixating the cable.

Use the include binders to tie the cables like below or what fits your installation.

Use included

binders to secure

the cables.

When using the screen

connector, you must not use

the “Relay-1” and “Relay-2”

connector also.

How to connect more than 2 relay boxes to one RS-232 Line

A standard RS-232 line only allows you to have two RS-232 devices attached. If you need more than two,

you have to use the Neets Serial splitter 1-4 as well. Below you can see how it can be connected.


Change the ID number of the relay box.

The relay box can be assigned an ID that allows up to 4 individual relay boxes to be

connected to the same RS-232 port.

When power is connected to the relay box the four led on the relay box will indicate the ID

number of the relay box for 3 seconds (See table below for details).

To change the ID number of the relay box you must connect power to the relay box and

within 3 second press and hold down the test button for four seconds. The test button you

press must correspond to the ID you want to assign.

Relay box ID LED status when power on

Test button to press when changing to this ID

None/0 Relay 1 + 2 + 3 + 42 1 Relay 1 2 Relay 2 3 Relay 3 4 Relay 4

2 This is the default settings.

RS-232 protocol

It is possible to control the relay box from a control system or a computer that is equipped with an RS-232

port.

Communication condition

The serial port on the device that controls the relay box must match the following:

Description Settings

Baud rate 9600 Data length 8 bit Parity bit None Stop bit 1 bit Flow control None

Commands

When entering all the commands in the Neets Control Utility software, select “Chr” as input format.

To easier understand the commands below please keep this in mind.

Please be aware that all the RS-232 commands are case sensitive. If the relay box detects an error in the

command line, the entire command will be ignored.

Sending multiple commands is possible without time delay between commands. Just remember that each

command must end with \CR.

To do this in the Neets Configurations Utility please look below:

We want to send two commands: Relay=1,Action=Set\CR and Relay=2,Action=Release\CR

Symbol Description

<X> When constructing the command, this part must be replaced with a sting or number. [ ] The braces indicate that what is inside only have to be included in the command the

function is required. In the command, the braces are not included.

\CR Every command line must end with a carriage return. Carriage return is commonly referred to as “CR” or if you need to enter it in hex the value is 0D and in decimal it is 13.


Controlling the relays

The RS-232 commands gives you fully control over all the relays.

You can do simple things like “Set”, “Release” or “Toggle” the state of a relay.

More advance functions like “Delay” and “Time” is also supported.

Command:Relay=<Y>,Action=<X>[,Delay=<W>][,Time=<Q>][,Unit=<Z>]\CR

Relay=<Y> Description

1-4 Set the number of the relay that you want to control.

Action=<X> Description

Set Set the relay Release Release the relay Toggle Toggle the relay. (if the relay is “Set” it will be “Released” and vice versa)

Delay=<W> Description

0-6553.5 Set the time (in seconds) from the command is send to the action is executed. The minimum step is 100 ms.

Time=<Q> Description

0-6553.5 Set the time (in seconds) from the action is executed to the relay returns to its original state. The minimum step is 100 ms.

This character has been entered by changing to

input format “Hex” and type in the value ”0D”

and then change bach to input format “Chr”.

306-0008-002-001 Rev500 Neets 4 relay

Below you find some examples on how to control the relays.

1. Activate relay 2 on all relay boxes connected.

Relay=2,Action=Set\CR

When entering this command in the Neets Configurations Utility it looks like this:

2. Activate relay 3 for 20 seconds on relay box with ID unit 2.

Relay=3,Action=Set,Time=20,Unit=2\CR

3. Toggle relay 4, 12 seconds after the command is send and then hold it for 5,8 seconds.

Relay=4,Action=Toggle,Delay=12,Time=5.8,Unit=2\CR

Unit=<Z> Description

0-4 Set the ID number of the relay box this command is intended to. If Unit number is 0 or not used the message will be send to all relay boxes.


Linking two relays together

As mentioned earlier, it is possible to link two relays together. Two linked relays are not able to be “Set” at

the same time and further more it is possible to define the time from one relay is released to the next can

be “Set”.

Command:Group=<G>,Action=<X>[,Delay=<W>][,Unit=<Z>]\CR

Below you find some examples on how to link and unlink relays together:

1. Link relay 1 and 2 together on all relay boxes connected.

Group=1,Action=Lock\CR

2. Link relay 3 and 4 together and set the safety delay to 3,6 seconds on all units connected.

Group=2,Action=Lock,Delay=3.6\CR

3. Unlink relay 1 and 2 on the relay box with ID number 3.

Group=1,Action=Unlock,Unit=3\CR

Group=<G> Description

1 Relay 1 and 2 2 Relay 3 and 4

Action=<X> Description

Lock Lock the selected group. Unlock Unlock the selected group. The relay in the group is no longer linked.

Delay=<W> Description

0-25.5 Set the time (in seconds) from one relay is released to the next in the group can be “Set”. The minimum step is 100 ms.

Unit=<W> Description

0-4 Set the ID number of the relay box this command is intended to. If Unit number is 0 or not used the message will be send to all relay boxes.

306-0008-002-001 Rev500 Neets 4 relay

Example In this section, you can read how an installation with projector, electrical screen, and electrical lift can be

done.

On the hardware side, we need:

1 projector

1 Neets Control - EU Professional or Neets Control - DK

1 Neets 4 relay box

Below you find the wiring diagram that shows the communication lines.


The relays now have the following functions.

Relay Function

Relay 1 Screen up (It takes 26 sec to move the screen up) Relay 2 Screen down (It takes 20 sec to move the screen down) Relay 3 Lift up (It takes 22 sec to move lift up) Relay 4 Lift down (It takes 22 sec to move lift down)

Then application must be able to control the system:

When the projector is turned on the lift and screen must move to the “down” position.

When the projector is turned off the lift and screen must move to the “up” position.

There must be a manual control for the screen.

Command to be used when turning on the projector:

Relay=1,Action=Release\CR

Relay=2,Action=Set,Time=20\CR



Command to be used when turning off the projector:





Command to be used when manually moving the screen down:


306-0008-002-001 Rev500 Neets 4 relay


Command to be used when manually moving the screen up:



Adding additional security

The system we have designed now is working and with the screen and lift wired up in high security mode,

there are no chances for shortening the motors.

Many motors specifies that a certain time is required from power is disconnected from one direction to

power is connected in the other direction.

By grouping the relays that controls the screen and lift, it is possible to define the time that must elapse

from one relay is “Released” to the next is “Set”.

Device Minimum time for changing from one direction to another

Screen 1,0 seconds Lift 2,5 seconds

The commands the must be used to achieve this function is:

Group=1,Action=Lock\CR

Group=2,Action=Lock,Delay=2.5\CR

It is only necessary to send the two commands one time, the settings will be stored in the relay box, also

after power has been removed.
