Introduction

This document aims to provide guidelines for the correct design and installation of the SM

4.0 system, which consists of the Weintek control panel and a variable number, from 1 to

31, of BCF231 coolers.

The user of this document will be responsible for:

1) defining the plant configuration, in particular:

- how many coolers to install and of what type (axial/centrifugal);

- defining for each one if it will work as a single machine or within an area;

- establishing the number of temperature/humidity probes;

2) checking that each machine communicates with its own control panel;

3) programming single or group operation;

4) programming manual or automatic operation;

5) programming the time slots in the event of automatic operation;

6) setting the temperature/humidity sensor on the selected parameter;

7) programming a limit for the aforementioned parameter;

8) programming the type of operation:

- Cool;

- Fan;

- Exhaust;

- Clean

9) sending the on-off command

10) checking any protections.

Level and Temperature/Humidity sensors

LEVEL SENSOR

Each BCF231 cooler, regardless of the configuration it will assume inside the system, must

have its own water level sensor. This sensor provides information on the amount of water

present in each machine:

1) tank empty;

2) tank half-full;

3) tank full.

On the control panel, by accessing the page dedicated to every single cooler, it is possible to

find a graphic representation of the water level inside it.

TEMPERATURE/HUMIDITY SENSOR

The units that will be configured as single or master of an area must be equipped with the

temperature/humidity sensor which is essential for their management. For slave units the

latter is not required but its use is in any case recommended, in order to maintain the option

of changing the system configuration in the future.

The sensor reads the temperature and humidity and it is up to the user to choose which of

the two parameters to use for the operation of the cooler, through the relevant drop-down

Page

03

Level and Temperature/Humidity sensors

menu. Once the reference parameter has been selected, the target will refer to the latter. In

particular, the cooler will remain active until the set temperature or humidity is reached and

will then go into standby immediately afterwards. If the temperature or humidity deviate from

the target, the cooler will be reactivated again, restoring the conditions prior to standby.

SHARED SENSOR

Each unit belonging to one of the 4 configurable areas shares the same

temperature/humidity sensor connected to the cooler defined as “Master” in the area and

determines its status. All other coolers assigned to the same area are defined as “Slave”

coolers and copy the behaviour of the master cooler. The area master or area slave status is

assigned through the drop-down menu of the temperature/humidity sensor, in particular by

setting the sensor as:

- “Local Temperature” …. . to define the Master cooler;

- “Local Humidity” ……… . to define the Master cooler;

- “Area Temperature” ….. to define the Slave cooler;

- “Area Humidity” ……….. to define the Slave cooler.

Hardware Set-Up

Through document BCF231_Configuration_V1 it is possible to create a mapping of the plant

that will be implemented by ticking the boxes prepared for the individual items, to define:

1) The type of machine to be installed;

2) Single or Area Operating Mode;

3) In the case of Area mode, which one;

4) If it is a Master or Slave Area;

5) With or without temperature/humidity sensor.

During installation it is advisable to set up a panel fitted with a circuit breaker at the base of

each cooler, to ensure the electrical safety of the device and facilitate maintenance

operations.

To minimise the length of the RS485 connection cable, a serial connection is recommended.

The electronic unit of each cooler is equipped with two ports for the serial line, to facilitate

this type of installation. The ports are fully interchangeable, both can be used as an input or

as an output from the cooler.

CABLE SPECIFICATIONS FOR RS485 SERIAL CONNECTION

It is particularly important for the correct operation of the system to make sure that the cable

chosen for the serial connection between the control panel and the coolers meets the project

specifications, otherwise it will not be possible to guarantee correct system operation.

In particular, the cable must be suitable for transmitting signals and commands for the

interconnection of instrumentation and control systems with digital signal transmission in

outdoor environments, requiring greater protection against electromagnetic (copper braid)

and electrostatic (aluminium/polyester tape) interferences.

Hardware Configuration

Each cooler must be assigned a progressive number from 1 to 31, this allows the system to

identify it and it is a crucial procedure. It is good practice to assign the coolers the number

corresponding to their position in the communication serial, this facilitates their identification

and helps to speed up the system. In the document BCF231_Configuration_V1 the position

of the dip-switches A0 and A1 is represented graphically for each cooler from No. 1 to No.

31. In a similar manner, the document presents the standard configuration for the T-

termination resistors, which involves their insertion only in the first and last machine of the

system. However, the final configuration must be verified in the field because a lot depends

on the type of cable used, its length and the number of machines in the plant.

Once the machines have been positioned, after having connected the water inlet and outlet

and the wiring of the power supply line and serial connection, it is advisable to proceed as

follows:

1) Connect machine No. 1 to the panel via the serial connection;

2) Power the panel and machine No. 1;

3) Log in to the panel by entering:

- “User Name” followed by “Enter”;

- “Password” followed by “Enter”;

- Select the desired language;

Page 07

Hardware Configuration

- Press the Home icon that appears at the bottom right to access the system.

- The first page accessed is called the Home page

4) From the Home page access the Configuration page to set the number of machines

in the system. To do this, click on the machines in the system that from grey will turn

blue. This step is extremely important because the scanning of the plant by the

control panel will only include the machines declared present. Machines that are not

declared as present will therefore be ignored by the system;

Page

Hardware Configuration

5) Go back to the Home page and check that the system recognises machine No. 1

correctly. (All the machines indicated as present will be white except for No. 1 which

will be light grey to indicate the fact that it is present but not configured).

6) Power machine No. 2, connect the serial line and check that it changes state on the

Main page;

7) Proceed in the same way for all the machines present.

This way of proceeding in steps allows problems on the communication line or on some

machines to be identified immediately, isolating the problem. The simultaneous activation of

the entire system, even if manageable by the system, requires a lot of time for

troubleshooting in the event of problems.

It is advisable to pay particular attention to the polarity of the contacts of the serial line, on

the panel and on the single machines, and to ensure that the cables are firmly inserted in the

terminals.

When configuring the hardware, check that the control panel shows the correct time, if this is

not the case, click on the arrow at the bottom right, select System Settings, enter the

password and access the Time/Date page to set the correct date and time.

Plant Configuration

Using the previously completed document BCF231_Configuration_V1 as a guide, assign

each machine its own setting as follows:

Single Machine Configuration:

1) In the relevant drop-down menu select “Single”;

Set the reference parameter (Temperature or Humidity) and the Target. Since it is a

single machine, the parameters will be of the “Local” type;

Page

Plant Configuration

2) Set “Automatic” or “Manual” operation and in the first case also set the operating

time slots, by defining a switch-on time and a switch-off time for each day of the

week. The cooler will be active within the time slot, while it will be in Standby outside

the time slot.

3) Set a function;

4) Set the fan rotation speed;

5) Turn on the machine.

Area Machine Configuration:

When configuring an area it is good practice to start from the “Master” machine as follows:

1) In the relevant drop-down menu select “Area 1” or “Area 2” or “Area 3” or “Area 4”;

2) Set the reference parameter (Temperature or Humidity) and the Target. Since it is

the Master machine, the parameters will be of the “Local” type;

3) Set “Automatic” or “Manual” operation and in the first case also set the operating

time slots, by defining a switch-on time and a switch-off time for each day of the

week. The cooler will be active within the time slot, while it will be in Standby outside

the time slot and so will all the Area slave coolers.

Page

Plant Configuration

4) Set a function;

Set the fan rotation speed;

Page

12

Plant Configuration

Turn on the machine.

Proceed as follows to configure the “Slave” machines

1) In the relevant drop-down menu select “Area 1” or “Area 2” or “Area 3” or “Area 4”;

2) Set the reference parameter (Temperature or Humidity). Since it is an Area but

Slave machine, the parameters will be of the “Area” type;

Since they are Slave machines, the other parameters will be inherited from the Area Master

machine

Important Note:

If a machine needs to be released from an “Area” to be assigned to another “Area”, it must

first be “Uninstalled”, and only subsequently configured as a “Slave” machine of the new

area. Once the operation is complete, access the single menu of the “Master” of the new

“Master” and reset the on and off times.
