PROFILE

Operator interface

Large LCD display with customization of
colors assigned to PV and SV display, of
color of plastic faceplate, and of logo.
Scrolling alphameric display of 25 mes­sages (32 letters each), completely confi­gurable and savable, in three languages.
Thanks to language selection and clear
scrolling messages for diagnostics, alarms,
and process state, the controller speaks
the user’s language.

Easy Configuration

Guided configuration for manual-free pro­gramming, with a few essential parameters
and on-line help messages.
Ability to clone configuration among con­trollers, even with power off and in the
field, thanks to a mini portable configurator
with Zapper battery.
Extended configuration, creation of work
recipes, and firmware updates via PC and
GF_eXpress software, even without powe­ring the controllers.
Thanks to the Smart Configurator function,
you obtain the required parameter recipe
by answering a few simple questions.
Local configuration and operation with
only four keys assigned to LEDs that ser­ve as feedback for the pressed key and as
guide to specify appropriate steps.

The initial parameters can always be reset,
both from the keypad and from the GF_eX­press Software tool.

Diagnostics, Preventive Maintenance,
and Energy Monitor

Complete diagnostics for broken or incor­rectly connected probe, total or partial load
break, out of range variables, and control
loop faults.
Thanks to the switching count and to the
settable alarm thresholds, you can pro­gram preventive maintenance to replace
worn actuators.
An internal energy counter with alarm for
abnormal variations totalizes energy con­sumptions and costs for constant control

Function block applications

Sixteen AND, OR, Timer Function Blocks
let you create customizable logic sequen­ces for complete and flexible machine con­trol.
The controller’s hardware resources are
exploited completely, without any need for
external devices such as timers and small
PLCs

Tuning

Advanced tuning algorithms ensure stable
and accurate control even with critical or
very rapid thermal systems, engaging au­tomatically when necessary.

Timer

Three types of timers let you set delay ti­mes before activating the control, hold ti­mes on the setpoint value, and timed chan­ges of programmed setpoints.

Setpoint Programmer

Models with twelve ramp and hold steps,
groupable in four programs, with enable
inputs and event outputs, are available for
applications with setpoint profiles.
On-board configuration and graphic confi­guration with GF_eXpress.

Valve Positioner

Models to control motorized valves, wi­thout feedback.
Valve position is calculated and shown on
the display.

General characteristics

The controller is completely software con­figurable without accessing the internal
electronics.
The universal main input accepts thermo­couple sensors, resistance thermometers,
and linears.
The controller can be replaced at any time
simply by removing the faceplate, without
any additional procedures.

DISPLAY AND KEYS

1

3

4 6

5

1. Temperature unit of measurement or number of program
running.

2. State of outputs OUT1, OU2, OUT3, OUT4.

3. Controller function states:

• RUN = setpoint programmer active;

• _/- = setpoint ramp active;

• TUN = PID parameters tuning active;

• MAN = manual/automatic (off = automatic control, on

= manual control);

9

• REM = remote setpoint enabled;

• SP1/2 = setpoint active (off = setpoint 1,

on = setpoint 2).

8

7

4. Work mode key (manual/automatic) in standard mode.
A function can be assigned via parameter but1.
The key is active only when the display shows the process
variable

5. Up/down keys: raise/lower the value of the parameter di­splayed on the SV or PV display.

6. F key: lets you navigate among controller menus and para­meters. Confirms the parameter value and selects the next
parameter.

7. Key pressed signals.

8. SV display: setpoint value, description of parameters, dia­gnostics and alarm messages.
Configurable with parameter dS.SP (default = setpoint).

9. PV display: process variable, parameter values.
