4...20 mA Current used as signal transmitted by
certain sensors or in a specific way to
control a device, such as a motorized
valve.
Alarm Output that trips when a certain condi-
tion is reached, for example, a defined
temperature
Auto Tune Function that lets you calculate and ea-
sily set the P, I and D parameters thanks
to the controller’s self-learning.
Cool Control used for cooling.
Heat/Cool Control used for both heating and coo-
ling (requires two control outputs).
Heat Control used for heating.
Hysteresis When, at a precise moment, the value of
the controlled quantity depends not only
on another reference quantity but also
on the values that the controlled quan-
tity had previously, there is hysteresis.
Hysteresis can therefore be considered
inertia that influences the control system,
causing variable delays between the
change of the reference quantity and the
change of the controlled quantity.
ON-OFF Control procedure based on activation
and deactivation of the output.
For heating, the output stays on until PV
is less than SV by a certain quantity (of-
fset), and then stays off until PV is not
greater than SV by the same quantity (or
different quantity, depending on control-
ler configuration).
For cooling, the output stays on until PV
> SV - offset and stays off until PV < SV
+ offset.
This type of control is not intelligent,
does not consider noise, and is not very
accurate, but ensures a limited number
of switchings of the output.
Overshoot Situation in which PV exceeds SV becau-
se the control action stopped too late.
The ON OFF controls have an overshoot
greater than the PID controls.
PID Acronym for Proportional-Integra-
tion-Differentiation, indicating a system
with negative feedback, i.e., a device
that acquires a value from a process in
input, compares it to a reference value,
and uses the difference (error) to calcu-
late the value of the controller output va-
riable, which is the variable that controls
the process.
The output is controlled based on the
current value of the error (proportional
action), on a set of previous error va-
lues (integral action), and on the speed
of change of the error value (derivative
action).
Pt100 A commonly used temperature measure-
ment device. At 0°C its resistance is 100
ohm, and at room temperature about
106 ohm. The Pt100 can be tested for
galvanic continuity and normal extension
cables can be used.
PV Acronym for Process Value, i.e., the value
that the process variable (temperature,
valve opening, etc.) has at that moment.
Solid state
relay
Also known as SSR, this is a relay desi-
gned specifically for frequent switching.
It has no moving parts or mechanical
contacts, but may still break or short cir-
cuit.
This type of relay is often used in tempe-
rature control systems such as PID.
Sensor Device that translates physical phe-
nomena (such as change in resistance
based on temperature) into electrical si-
gnals that can be acquired and proces-
sed by the controller
Setpoint Set value (see SV).
SV Acronym for Set Value, i.e., the value that
the process variable (temperature, valve
opening, etc.) has to reach and maintain.
Thermocouple Sensor that transmits an electrical signal
of a few millivolts. Cannot be tested for
galvanic continuity. It needs specially de-
signed extension cables

80208G_MHW_650-1250-1350_01-2017_ENG

Undershoot Situation in which PV does not reach SV
because the control action stopped too
soon.
The ON OFF controls have an undersho-
ot greater than the PID controls.
Control
output
Output that controls the process and is
switched on and off as needed.

1. GENERAL DESCRIPTION
1. GENERAL DESCRIPTION
1.1. Profile
The 650, 1250 and 1350 controllers are a family of devices
designed to control temperature in industrial processes and
to manage the positioning (without feedback) of motorized
valves.
The 3 devices have the same main characteristics and the
same range of functions. They differ in size (1/16, 1/8 and 1/4
DIN), the amount of information shown on the display, and
the maximum number of digital inputs.
The displays show the process and setpoint values, plus
multilingual scrolling messages for diagnostics, alarms and
process state.
On models 1250 and 1350, a segmented bar graph shows
percentages of power, delivered current or valve position.
Configuration/local operation is done with keys (4 on the 650
and 1250, 6 on the 1350), to which dual-function LEDs are
associated: feedback for pressed key and guide for permit-
ted operations.
Commissioning is simplified by guided configuration for ma-
nual-free programming, with just a few indispensable para-
meters accompanied by inline help messages.
The configuration can be cloned among controllers without
having to switch on the power supply thanks to the Zapper,
a battery-operated portable mini-configurator (to be ordered
separately).
With GF_eXpress software and PC, you can program the ex-
tended configuration, create work recipes and update the
firmware without having to switch on the controllers.
Thanks to the Smart Configurator function, you obtain the
required parameter recipe by answering a few simple que-
stions.
The initial parameters can always be reset, both from the
keypad and from the GF_eXpress software.
The devices offer complete diagnostics (broken or incorrect
connection of sensor, total or partial load break, off-scale of
variables and control loop faults), operation count, settable
alarm limits (useful for scheduling preventive maintenance),
and an internal energy counter to totalize energy consump-
tion and cost to achieve continuous control.
Sixteen AND, OR and Timer Function Blocks let you create
customizable logic sequences for complete and flexible ma-
chine control.
The controller’s HW resources are exploited completely, wi-
thout any need for external devices such as timers and small
PLCs.
Tuning is performed via advanced algorithms that ensure
stable and accurate adjustments, even with critical or very
fast heating systems, and that engage automatically when
necessary.
Models with twelve ramp and hold steps, groupable in four
programs, with enable inputs and event outputs, are avai-
lable for applications with setpoint profiles.
The controller can be configured directly with the keys or
graphically via GF_eXpress software.
Maintenance of the system in which the device is installed
is made easier by the ability to replace the controller at any
time simply by removing it from the faceplate.
No additional steps are needed.
