LUCRE Series


“Top of the Range”

1

To maintain precise environment condition, SABRO (lucre series) has produced a new

range of precision air conditioning units.

These units have been designed and developed to meet the air conditioning needs of

data processing center, digital telephone exchange, computer room and other

technological environment which radiate high heat.

For the safe and trouble free operation of such Hi-tech equipment, it is very essential to

remove heat generated and keep the constant temperature and humidity control

around the year. The ordinary air conditioning equipment which are intended for the

comfort cooling are designed while keeping in view the comfort of the people in the

room / area and these equipment are generally not able to ensure the environment

conditions for Hi-tech technological equipment, especially when there are elevated

heat load.

But on the other hand precision air conditioning application is based on four main

objectives which lead to important design conditions; these four main objectives

distinguish the precision air conditioning from ordinary air conditioning equipment for

comfort cooling. These are

Precise control of environment condition such as temperature and humidity.

High air flow rate

Round the year operation (365 days-24hours) under all ambiance conditions.

Energy efficiency (High E.E.R)

It is established , when air conditioning the room / area for telephone exchange and

data processing, the amount of heat load is very high as much as 6-10 times the amount

of heat load of comparable area used in commercial offices for comfort cooling.

The high heat generating equipment in data center / exchange has changed the

philosophy and configuration of design air conditioning solution.

To fulfill the requirements of new technology applied in data center, SABRO has

designed a series of precision air conditioning equipment which guarantees optimum

regulation of temperature providing correct distribution, filtration, cooling ,and humidity

control for the modern equipment in high load IT environment.

General Description

Temperature Control,

Humidity Control,

High Air Flow,

To control the precise temperature, SABRO precision air conditioning units are

designed with sophisticated microprocessor controller. This controller is also able to

react promptly to any major change in heat load and temperature.

The sophisticated electronic equipment installed in the room must be protected both

from condensation in side the room and any static electricity charge. To protect the

equipment, it is essential to control the extremely accurate humidity level in the room; in

fact an excessively high humidity level can lead to condensate formation on the

electronic equipment, whereas if the humidity level is too low there is a danger of a build

up of static electricity [R.H. <30%] .Both conditions are potentially harmful to the

electronic equipment and must be prevented and avoided.

In order to guarantee high sensible heat ratio SABRO precision air conditioning units are

designed with specific high air flow rate. The rooms in which telephones of data based

equipment are installed require high air flow to cope with the excessive heat load.

Year-Round Operation,

The Lucre precision air conditioning range is designed to operate all the year in high

ambient temperatures. During design all the technical and procedural discussion is

made for the achievement of high degree of reliability for the equipment.

LUCRE's (HSPWM) output

Lucre's User friendly and powerful instruction sets

Lucre's Communication function (up to 5 ports including RS232,RS485, USB, Ethernet and GSM)

Integrated high-speed counters with counting frequency up o 920 Khz

The SoC inside the Lucre PLC incorporates four sets of hardware high-speed pulse width modulation outputs with a maximum frequency of 184.32KHz and 18.432KHz with resolutions of 1% and 0.1%, respectively. Different from the PWM function operated by software alone in other brands of PLC, the hardware driven high-speed PWM in the Lucre PLC operates with high precision and stability which provides the user easy control with precise accuracy.PLC's design incorporates a “System on Chips“(SoC) developed in-house.The chip consists of over 120,000 gates which integrates powerful features such as a Central Processing Unit (CPU), Hardware Logic Solver (HLS), five high-speed communication ports, four sets of hardware high-speed counters / timers, four axes of high-speed pulse outputs for NC positioning control (with linear interpolation or dynamic tracking) 16 high-speed interrupts or captured inputs. The FBs represents high functionality and reliability with exceptional value compared to other

The Lucre-PLC has more than 300 instructions which adopts a user friendly and readable multi-input/multi-output function structure, with multi-input instruction structure can derive many types of functionality which other brands of PLC's may require the use of many instructions to achieve this. Also the operation result can be directly sent to internal or external outputs. To increase the program readability, the inputs or outputs for each function instruction have their own mnemonic symbol attached and the content of each operand is also displayed. For high-end applications, such as PLC networking (LINK), PID control and NC positioning etc, the PLC provides dedicated convenient instructions to assist in program development

Via the five high-speed communication ports included in the SoC, Lucre's PLC's communication capability is outstanding with all five ports operating at a maximum speed of 921.6Kbps. Communications can be achieved using ASCII code or the double-speed binary code. Along with standard protocol, Modbus ASCII/RTU/TCP or user-definable protocol are also available. The PLC also provides the option of six different communication boards and eight different communication modules for various types of communication applications. With their high speed and functionality the FBs-PLC has the greatest number of communication ports than any other PLC in its class. Each communication port comes standard with LED indicators for transmission (TX) and reception (RX) to enable the user to monitor the operation.

The Lucre-PLC as standard has up to 4 sets of hardware high-speed counters (HHSC) and 4 sets of software high-speed counters (SHSC). The highest counting frequency of a HHSC is 200 KHz (MC) or 920 KHz (MN). Each HHSC also has a clear and mask function. There are 8 counting modes including U/D, U/Dx2, P/R, P/Rx2, A/B, A/Bx2, A/Bx3 and A/Bx4 which makes the HHSC very powerful and efficient. For example, if the encoder, running at 200 pulses per revolution, adopts A/Bx4 mode the FBs-PLC can achieve the same result that a 800 pulses per revolution encoder can provide. The counter is implemented in the hardware so as not to occupy CPU processing time.

High-speed timers (HST)

General Features

Luc er P cision Air Cond ioners re it


NC Position Control is incorporated into the SoC of the FBs-PLC which integrates PLC+NC control into one unit in order for resources sharing and reducing the need of data exchange. The NC position control adopts special positioning command language, which allows programming by mechanicalor electrical units and changing control parameters during execution. One single unit has up to four axes outputs with a maximum frequency of 200KHz (MC) or 920KHz (MN) and equipped with multi-axial linear interpolation and dynamic tracking. If combined with the four sets of built-in HHSC, it can achieve positioning control with closed loop precision.

The PLC is the only PLC in this class providing 0.1mS high-speed timers (the PLC having one 16-bit and 4 sets of 32-bit HST). Currently, the fastest time base of high speed timers used in other brands of PLC's is 1mS. By incorporating the interrupt function of the PLC the accuracy of 0.1mS time base high-speed timer of FBs-PLC is further enhanced and can easily achieve more precise speed detection or can be used as a frequency meter. In most cases, expensive speed detection equipment can be replaced
