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

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

Communications
The Brooks SLA5840 is also available with DeviceNet
TM
communication capability. DeviceNet is an open digital
protocol capable of high speeds and easy system connectivity. Brooks Instrument has several of its devices
available on this popular networking standard, and is a member of ODVA
TM
(Open DeviceNet Vendors Association),
the governing standard body for DeviceNet.
DeviceNet
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)

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.
