GENERAL CHARACTERISTICS

DIGITAL P.I.D. THERMOREGULATOR
with one output

EC 4-173

* Frontal size: 48 x 48 mm.

* Power-supply: 230 Vac (standard).

* Configuration parameters accessible through Pass-

word.

* Custom configuration through keyboard (standard) or

Personal Computer (on request).

* Easy integration with remote-assistance or

remote-managing.

EC 4-173 is a digital one output P.I.D. temperature controller designed to cover a temperature range from 0 to +999 °C, meeting the needs

of a wide part of the applications of accuracy in heating field.

In factory, the instrument gets set to accept, at the input, "J" (Iron-Constantan) or "K" (Chromel-Alumel) thermocouples and is provided of a

"Auto-tuning" function activable through a key located on the front panel of the instrument, it is studied to permit the instrument to compute
the optimal value of the parameters used during the temperature regulation, in order to use them during the conclusive part of the regulation.

The SPDT relay-output can manage (up to) 8 A loads at 250 Vac and it is supplied in standard version; as option it is possible to request an output

with low-voltage signal, suitable to drive the SSR modules (solid state relay).

The flashing signals on the display have been studied in order to catch user's attention in case of not proper functioning: defective probe, temperature

outside the limits permitted by the used probe or corrupted memory-data.

The instrument is provided of one temperature alarm that can be disabled, configurable in six different ways of working; the intervention of the

alarm determines the appearing on the display of the indication "AL1" alternated to the temperature read by the probe.

* 3 digits display, height 12,5 mm.

* P.I.D. temperature regulation.

* "Auto-tuning" function studied to compute the

optimal value of the parameters used during the
temperature regulation.

* 1 widely configurable temperature alarm.

* 1 relay-output (8 A at 250 Vac).

MOUNTING

For a proper mounting take note of the attached indications; be sure that the conditions of use (voltage of power-supply, environment temperature,

humidity) are inside the indicated limits.

Do not overload the relay-output keep inside the indicated limits.

WARNING: the instrument is not protected from overloads; so it is necessary to give the output the suitable protections.

The power-supply is protected by an internal fusible.

CONFIGURATION

There are two Levels of configuration (Level 2 is protected by Password):

Level 1

Push and at the same time for 4 seconds at least: the parameter PA appear on the display.

Push or to select the parameter to modify at Level 1.

Push and or to modify the selected parameter.

Level 2

From Level 1 push or to select the parameter PA.

Push and or to set "-19".

Push and at the same time for 4 seconds at least: the first parameter of Level 2 will appear on the

display.

Push or to select the parameter to modify at Level 2.

Push and or to modify the selected parameter.

How to leave CONFIGURATION

Push and at the same time for 4 seconds at least or wait 50 seconds at least without operating

on the keyboard (exit for time-out) or try to switch the power-supply off and then, switch

it on after 1 second at least since the last modify.

WORKING TEMPERATURE SETTING

In normal operating conditions the instrument displays the value read by the probe.

Push and release the key to display the actual setpoint value: the led "out" flashes to indicate that a procedure of setpoint setting is on run;

to change the value operate on the keys or within 4 seconds since the pressure on the key .

The exit from the procedure of setpoint setting can be obtained pushing and releasing the key or waiting 4 seconds at least without operating

on the keyboard (exit for time-out).

NOTES - the setpoint is programmable within the limits set through the parameters r1 and r2.
