PROFILE
Operator interface
Large LCD display with customization of
colors assigned to PV, SV and F display, of
color of plastic faceplate, and of logo.
Graphic display of power, output current or
valve position. 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.
The operator interface provides two additional display dedicated to the permanent
display for: Nr. of step and Nr. program.
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.

1. Temperature unit of measurement or number of program
running.
2. State of outputs OUT1, OU2, OUT3, OUT4.
3. Displays program number, step number, unit of measurement (%, A, kW, kWh).
4. Controller function states:
• RUN = setpoint programmer active;
• _/- = setpoint ramp active;
• TUN = PID parameters tuning active;
• MAN = manual/automatic (off = automatic control,
on = manual control);
• REM = remote setpoint enabled;
• SP1/2 = setpoint active (off = setpoint 1,
on = setpoint 2).
5. 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.
6. Key function configurable with parameters but2 and but3.
The keys are active only when the display shows the pro-
cess variable.
7. Up/down keys: raise/lower the value of the parameter displayed on the SV or PV display.
8. F key: lets you navigate among controller menus and parameters. Confirms the parameter value and selects the next
parameter.
9. Key pressed signals.
10. Displays percentage of power or current, configurable with
parameter bArG.
11. Display F: parameters, diagnostics and alarm messages.
Configurable with parameter dS.F (default = setpoint).
12. SV display: parameter values. Configurable with parameter
dS.SP (default = setpoint).
13. PV display: process variable.
