1-1 Description
The Brooks microprocessor based readout and control equipment is
designed to meet the highest standards with user-friendly operation. Model
0152 provides 2 channels and Model 0154 provides 4 channels. 0152/
0154 also provide power supply for Brooks gas/liquid thermal mass flow/
pressure controllers/meters and QUANTIM
TM
. The readout function is a
back lit 4 x 20 character display. Features include membrane push buttons
for setpoint, blending, valve override and local/remote control. Actual
reading or % full scale of flow rate/pressure/density/temperature is
programmable for each channel.
Both models can be operated with independent mass flow control
channels, or with one or more channels slaved to the master (blending
mode). (If planning to use blending mode with engineering units rather than
% full scale, 1-5 Vdc or 4-20 mA I/O cannot be used.) Each channel can be
operated as master or slave or in an independent control mode. Valve
override functions are selectable. In valve override mode, the valve will be
open/closed independent of setpoint value. The Mass Flow Controller
Output Signals are switched to the 25-pin connector located on the
backpanel. This connector includes up to 4 channels with setpoint input
and flowrate or pressure output.
An RS-232 port is provided standard to control the 0152/0154 from a PC.
This port enables connection of up to 4 analog (or analog configured
devices) to a Model 0154. Communications is possible with optional cable
and software (Standalone and LabVIEW
TM
VI with Smart DDE driver).
Setpoint, Flow Rate and Valve Override parameters are available.
The local function is useful as backup of the customer's system
configuration. In local mode, the Mass Flow devices will be operated
directly by the 0152/0154, and in remote mode the customer's peripheral
equipment determines the control actions. Stored default values are
available after power interruption
