1-3 Description

The Brooks

®

Model SLA5840 Pressure Controller/Flowmeter is designed to

control pressure while also measuring flow rate. The Model SLA5840

receives a remote pressure transducer signal, and using adjustable

integral PID control electronics and control valve, will maintain a desired

set pressure. The Model SLA5840 can also be configured as a mass flow

controller for calibration or test purposes.

Brooks now offers control interface with DeviceNet and Profibus, two high-

speed digital communication networks. Other network protocols are in

development. Talk to your Brooks representative about your specific needs.

The MFC's microprocessor uses a multi-point calibration curve, to deal

with residual sensor non-linearity, yielding a highly accurate process signal.

The microprocessor then executes Brooks’ proprietary Adaptive Valve

Control algorithm to rapidly adjust the valve actuation to match setpoint.

Process data and commands may be wired using either traditional analog

connections or digital communications networks, the measurement and

control performance is the same!

The SLA5800 family of products takes advantage of modular design in

both mechanical and electrical construction. This modularity allows for

simplified customer ordering and factory configuration, enabling Brooks to

more easily meet the ever changing needs of our global customers.

Brooks' production flexibility translates into reduced lead times for our

customers. This flexibility allows products using both traditional analog

connections or leading edge network communications protocols.

The SLA5800 series of controllers can directly replace existing analog

products bringing with them greatly improved accuracy. Analog and digital

applications will see settling time improvements with an insensitivity to

varying process conditions, due to Brooks' proprietary Adaptive Valve Control

algorithm.

Figure 1-1 SLA5840 Analog/RS485 Connections and Pinouts

RS485 Communications

The Brooks Digital Series is equipped with RS485 communication capability. Refer to Figure 1-2 (Analog I/O pin

connections), that enables the device to communicate via a personal computer for process control.

Baud rate selections for the Brooks Digital Series related to RS485 are: 1200, 2400, 4800, 9600, 19200 and 38400

baud and can be selected via the Brooks Expert Support Tool (BEST).

The RS485 is essentially a multidrop connection. It allows a maximum of 32 devices to be connected to a

computer system. IBM-compatible PC's are not equipped with RS485 ports as standard. An RS232/USB to RS485

converter or RS485 interface board is therefore required to connect an RS485 network to a standard PC. The

RS485 bus, a daisy chain network, meaning that the wires are connected at the units.

Note: Aux Input is used for Remote Transducer Pressure Controllers only.

Profibus

Communications

The Brooks SLA5840 is now equipped to support the Profibus communication protocol. Profibus is a fieldbus-

based automation standard of Profibus and Profinet International (PI). Via a single bus cable, Profibus links

controller or control systems with decentralized field devices (sensors and actuators) on the field level and also

enables consistent data exchange with higher ranking communication systems. A 9-pin sub-D connector is

included on every device and is galvanic isolated from the main electronics as defined by the EN 50170 Profibus

standard to allow easy network connection separate from the main connector. The main 15-pin sub-D connector

or termination board is still needed for the power supply, but also allows for the standard analog I/O signals,

analog valve override, and (open-collector) alarm signaling to be used separate from the network connection.

The communication electronics allows for automatic baud rate detection ranging from 9600 baud to 12 Mbaud,

thus making the need for any hardware baud rate selection methods not required. For selecting the device

address, which must be unique on the network, two rotary switches are provided. This allows a user to easily

select any address number ranging from 0 to 126. This can provide fast device replacement without complex

network configurations. The Profibus-DP piggyback board is equipped with a zero command pushbutton, allowing

the user to give a manual command to the device to (re)balance the flow sensor electronics. This command can

also be issued through the protocol.

The Profibus-DP communication option supports the following message types:

• Cyclic data exchange (Write/Read data).

• Read inputs (e.g. status, flow, temperature, totalizer, etc.).

• Read outputs (e.g. commands, setpoint).

• Global control commands (e.g. fail safe, sync).

• Get configuration (i.e. read number of I/O bytes and composition).

• Read diagnostics information (i.e. get error and alarm status).

• Set parameters (i.e. select gas number, engineering units, I/O configuration

• Set parameters (i.e. select gas number, engineering units, I/O configuration etc.).

• Check configuration (i.e. check I/O composition).

is similar to the RS485 standard in that it is a multi-drop connection that allows a maximum of 64 devices to

be connected on the same network. Baud rate selections for DeviceNet

products are 125K, 250K and 500K and can

be selected via MAC ID switches mounted on the device.

The DeviceNet

communication link also provides access to many of the Brooks SLA Digital Series functions for

“control and monitor” operations, including:

• Accurate setpoint adjustment and flow output measurement (including units of measure selection)

• PID Settings (controller only)

• Valve Override (controller only)

• Calibration Gas Select

• Soft Start Control (controller only)

All flow instruments returned to Brooks requires completion of Form

RPR003-1, Brooks Instrument Decontamination Statement, along with a

Material Safety Data Sheet (MSDS) for the fluid(s) used in the instrument.

Failure to provide this information will delay processing by Brooks

personnel. Copies of these forms can be downloaded from the Brooks

website www.BrooksInstrument.com or are available from any Brooks

Instrument location listed above.

2-5 Removal from Storage

Upon removal from storage, a visual inspection should be conducted to

verify the condition of the equipment is “as received.” If the equipment has

been in storage in conditions in excess of those recommended

(See Section 2-3), the device should be subjected to a pneumatic pressure

test in accordance with applicable vessel codes.

2-6 Gas Connections

Prior to installation ensure all piping is clean and free from obstructions.

Install piping in such a manner that permits easy access to the instrument

if removal becomes necessary.

2-7 Installation

Recommended installation procedures:

a. The SLA Enhanced RT should be located in a clean, dry atmosphere

relatively free from shock and vibration.

b. Leave sufficient room for access to Self-zero function push-button.

c. Install in such a manner that permits easy removal if the instrument

requires servicing.

d. The SLA Enhanced RT can be installed in any position. However,

mounting in orientations other than the original factory calibration

(see calibration data sheet supplied with the instrument) can result in a

±0.5% maximum full scale shift always re-zero following orientation

change and warmup.

e. When installing a mass flow controller or meter with full scale flow rates

of 10 slpm or greater, be aware that sharp, abrupt angles in the system

piping directly upstream of the controller may cause a small shift in

accuracy. If possible, have at least ten pipe diameters of straight tubing

upstream of the mass flow controller or meter. This is not required for

meters with an integrated filter.

2-8 In-Line Filter (See Table 2-1)

It is recommended that an in-line filter be installed upstream from the mass

flow controller or meter to prevent the possibility of any foreign material

entering the flow sensor or control valve. The filtering element should be

replaced periodically or ultrasonically cleaned.

2-9 Electrical Interface (Reference Figures 2-1 thru 2-4)

SLA Enhanced RT's are controlled using analog signals or digital control via

RS485, DeviceNet or Profibus. For an analog unit the minimum set of

connections which must be made to the pressure controller include: power

supply+ , supply common, setpoint, setpoint common, output signal and

output signal common. All signals are supplied via the 15-pin 'D' connector.

SLA Enhanced RT's electrical interface is designed to facilitate low-loss

and quiet signal connections. Separate returns (commons) are supplied for

the analog setpoint, analog flow signal, and the power supply. These

commons are electrically connected together on the PC board.

Voltage I/O Version

• Signal Common

• Signal Output

• +13.5 to +27 Vdc Supply

• Setpoint Input

• Setpoint Common

• Supply Common

For a DeviceNet unit, 11-25 Vdc power and communication I/O are

supplied via the standard 5-pin Circular Micro-Connector.

For a Profibus unit, the power and analog signals are via the 15-pin 'D'

connector. The Profibus communication signals are via the auxiliary 9-pin

'D' connector.

Refer to Figure 1-1 for analog/RS485 pin connections, Figure 1-2 for

Profibus pin connections and Figure 1-3 for DeviceNet pin connections.

Refer to Figures 2-2, 2-3 and 2-4 for typical electrical I/O configurations.
