GENERAL
Microprocessor setpoint programmer and
controller, format 48x96 / 96x96 (1/8 DIN
- 1/4 DIN).
Manufactured using SMT, the instrument
provides a complete operator interface,
protected by a Lexan membrane that
ensures level IP65 faceplate protection.
It has 4 keys, two green LED displays,
each with 4 digits, 4 red indicating LED’s
for the 4 logic or relay outputs, and a
further 3 LED’s that are programmable to
indicate the various operational states of
the instrument.
10 led red bargraph indication can be
associated with analogue outputs for
control, inputs or deviations.
The main input for the process variable is
universal and provides the possibility to
connect many types of input sensor:
thermocouple, resistance thermometer,
thermistor, linear inputs, potentiometer, all
with the possibility of custom linearisation
that can be defined using the faceplate
keys. The type of input is selected from
the faceplate keys and no external shunts
or adapter are required.
A second auxiliary isolated analogue
input is available, which can also be
configured for a linear input,
potentiometer or current transformer.
There are two isolated digital inputs for
entering the program commands of start,
stop and reset, choosing the program and
to step through the program.
The instrument can have up to 4 relay
(5A/250V) or logic (11Vdc, 20mA) outputs
and up to 2 isolated analogue outputs in
voltage or current.
The function of each output is
configurable and event outputs linked to
the individual program step as well as
control and alarm functions can be
provided.
A further isolated output (10 or 24Vdc,
30mA max.) is available for powering
external transmitters or potentiometers.
The serial communication interface
RS485 (RS232C compatible) makes it
possible to read or modify any parameter
and to govern the instrument online
(local/remote manual/automatic
commutation, internal timer control, direct
control of outputs).
Protocols available: MODBUS RTU and
CENCAL (Gefran).
The sequence for setting up the
programmer is particularly brief and there
are up to 8 steps, each with a setpoint
ramp and hold.
It is also easy to set up any interlocks
required from logic inputs and the event
outputs, as well as the type of restart
preferred using the few set-up steps in
the “Step” menu.
The various steps can be regrouped in 4
different programs.
All the programming procedures of the
instrument are facilitated by the grouping
of the parameters in function blocks (
CFG
for the control parameters, Inp for the
inputs, Out for the outputs, etc.) and by
the possibility of selecting a simplified
menu for entering the most frequently
used parameters.
The instrument can also select the
parameters is needs to display as a
function of the hardware configuration,
automatically concealing those that are
not influential.
To simplify the configuration even further,
a programming kit is available for PC,
which includes a menu driven
configuration program for Windows and
the necessary cable to connect the
instrument (see data sheet
cod.WINSTRUM).
The programmer, as well as executing
the program controlling the main output
(heat/cool with two independent PID
loops), can also retransmit 2 different
setpoint profiles, with a common time
base, to a slave controller using the two
analogue outputs.
In the execution phase of the
programmer, the two displays are used to
monitor the behaviour of the program and
make any necessary adjustments
immediately.
A - PV Display: process variable
B - SV Display: setpoint value
C - “Function” key
D - “Lower” key
E - “Raise” key
F - “Automatic/Manual” selection
G - Function indication
H - Indication of active outputs
