INTRODUCTION
THE CONTROLLERS
The CAL 3300 1/32 DIN and the CAL 9300 1/16 DIN miniature
controllers share the same PID control strategy and features
while giving the user the flexibility of a choice of panel
format. Control can be optimised with a single shot autotune
either on initial warm-up or at setpoint. A second setpoint
can be configured in a variety of alarm modes or PID Heat-
Cool strategy. A programmer offers a single ramp to setpoint
with a choice of timed soak period before switching off the
output.
Control of non temperature processes is achieved by the
provision of linear input ranges and scaling in commonly
used engineering units.
Serial communication is available as an option on both
controllers, and the easy to use
CALCOMMS
TM
is a graphic
WINDOWS
TM
based software package designed for PC
supervision of up to 32 instruments, for remote adjustment,
configuration, cloning, saving and retrieving settings to files
and logging and charting in real time.
CALCOMMS
TM
uses the MODBUS
®
protocol via either a fully
isolated RS232 or RS485 link depending on the number of
instruments and the transmission distances involved in the
application.
A users manual is supplied with the comms option. For more
information contact CAL. For details, see rear cover.
It is suggested that users read the
OVERVIEW
section of this
manual before any installation or setting-up procedures are
undertaken.
Note:
The controller will not be operational until either the
QUICK-START
or
SET-UP
procedure has been
completed.
NB:
Please note that in the manual, functions are
