CONNECTIONS
Power supply input:
do not supply the temperature controller directly through power lines and
avoid installing near electric motors or other sources of electrical disturbance.
Resistance thermometer input (RTD):
ensure all conductors used to attach the resistance thermometer are alike and
with a resistance less than 4 ohms/each; when using a 2 wire resistance
thermometer, link terminals 13 and 14 together.
Thermocouple input (TC):
connect the sensor using the correct compensated extension cable for the
utilized thermocouple.
Relay output:
in case of connected inductive loads, the maximum current permitted through
the contacts decreases in relation to the power factor.
Transistor output:
when the output is high, the ON1 LED lights, the terminals 1 (+) and 3 (-) have
a rating of 15 Vdc 20 mA, protected and suitable to drive a Solid State Relay
(SSR), recommended in case of high currents or frequent switching.

VIEWING AND SETTING OF THE 1st SET POINT
1st configuration level
To view the set point in the single display version, depress the SET key. To
modify the set point act directly on the UP/DOWN keys, the new value is
updated automatically when the indication UPDT appears or the SET key is
pressed. By keeping the UP or DOWN keys depressed, the value will change
at first slowly and then quickly. During the setting operations, regulation
continues with the last stored value. The setting is locked if the option LOC1
is selected and the LOCK LED is lit up.
MANUAL REGULATION OF THE OUTPUT POWER
To change from automatic regulation (closed loop) to manual (open loop),
keep the AUTO/MAN key depressed until the MAN LED turns on. The output
power is at zero, make the 1st point setting operations to set the value from
M0 to M100%. The regulator maintains the set value if switched off in manual
regulation. To return to automatic regulation, keep the AUTO/MAN key
depressed until the MAN LED turns off.
VIEWING AND SETTING OF THE 2nd SET POINT
2nd and 3rd configuration levels (see the diagram on the right)
To enter the 2nd and 3rd configuration levels, keep the PROG key depressed
for more than 2 seconds. To change the values or the selections, use the
UP/DOWN keys. To confirm and continue the configuration, depress the
PROG key; to confirm and exit, depress the SET key. At the end of each level
[End2] or [End3], you can repeat it by depressing the PROG key for less than
2 seconds or you can change the level by depressing the PROG key for more
than 2 seconds. During the program scrolling the regulation continues, but it
stops when a modification occurs. The setting exits automatically if no key is
depressed within 30 seconds.
PROGRAMMING NOTES
A) in case of second point with dead zone, the indication [2 LO] will appear followed by
the lower limit value, then [2 HI] followed by the higher limit value; the autotuning
selection will appear only in case of PID control action.
B) in case of relay 1st point output, a minimum cycle time of 20 seconds [t 20] is
recommended.
C) adaptative function to improve the response to frequent or fast variations of the
load, i.e. start and stop process.
D) settings not included in the sensor scale or in the setting limits, are automatically
corrected with the nearest threshold limit value.
E) in case of Fahrenheit degrees selection, please cover the °C symbol on the front
panel with the label °F which is supplied with the controller.

ERROR AND TEST MESSAGGES
Underflow, indication below the sensor range. Short circuit of the sensor
RTD Pt100 or interruption of the compensation connection.
Overflow, indication over the sensor range. RTD Pt100 or TC sensor
broken or interruption of the main connection.
Au...-test, if the message remains fixed the controller must be repaired.
General failure; the controller must be repaired.
LFA: DETECTION OF FAULTS IN THE REGULATION LOOP
Loop Fault Alert: with the 1st point output 100% ON state the measured
temperature is not changed according ... the control action within the
s...red integral time; a fault in the regulation loop is possible: wrong
configuration, lack of power, heater or cooler broken, thermocouple short-
circuited or polarity reversed, etc. ... reset the LFA function, please modify the
configuration or the set-point, or switch the temperature controller off and then on again.
The function LFA is not active in the following cases: with output lower than 100% ON,
with integral time at zero, during the au...tuning, in manual position.
NOTE: In case of OvFL, UnFL, 8888, FAIL, LFA2, the first point output is turned off.
