MEASUREMENTS AND INSTALLATION
Measurements in mm (in); 39.5 (1 9/16) depth with fixed screw terminal blocks, 52.5 (2 1/16)
depth with plug-in screw terminal blocks.
To be fitted to a panel, snap-in brackets provided.
INSTALLATION PRECAUTIONS
-
the thickness of the panel must be between 0.8 and 2.0 mm (1/32 and 1/16 in).
-
ensure that the working conditions are within the limits stated in the
TECHNICAL
SPECIFICATIONS
section.
-
do not install the device close to heat sources, equipment with a strong magnetic field,
in places subject to direct sunlight, rain, damp, excessive dust, mechanical vibrations
or shocks.
-
in compliance with safety regulations, the device must be installed properly to ensure
adequate protection from contact with electrical parts. All protective parts must be
fixed in such a way as to need the aid of a tool to remove them.

ELECTRICAL CONNECTION
N.B.
- use cables of an adequate section for the current running through them.
- ensure that the thermocouple is properly insulated from contact with metal parts or
use an already insulated thermocouple.
- if necessary, extend the thermocouple cable using a compensating cable.
- to reduce any electromagnetic interference locate the power cables as far away as
possible from the signal cables.
PRECAUTIONS FOR ELECTRICAL CONNECTION
-
if using an electrical or pneumatic screwdriver, adjust the tightening torque.
-
if the device is moved from a cold to a warm place, humidity may cause condensation
to form inside. Wait for about an hour before switching on the power.
-
make sure that the supply voltage, electrical frequency and power are within the set
limits. See the section
TECHNICAL SPECIFICATIONS
.
-
disconnect the power supply before carrying out any type of maintenance.
-
do not use the device as a safety device.
-
for repairs and for further information, contact the EVCO sales network.

USER INTERFACE AND MAIN FUNCTIONS
4.1
Switching the device on/off
To switch on push encoder models:
1.
Press the encoder.
To switch off push encoder models:
1.
Press the encoder for 2 s.
To switch on touch key models:
1.
Touch the ON/STAND-BY key.
To switch off touch key models:
1.
Touch the ON/STAND-BY key for 2 s.
If the device is switched on, the display will show the P5 value ("regulation temperature" de-
fault); if the display shows an alarm code, see the section ALARMS.

If Loc = 1 and 30 s have elapsed without the keys being pressed, the display will show the
"
Loc
" label and the keypad will lock automatically.
4.2
Unlocking the keypad
Touch a key for 1 s: the display will show the label “
UnL
”.
4.3
Setting the setpoint
For push encoder models:
1.
Rotate the encoder.
2.
Rotate the encoder within 15 s to set the value within the limits
r1 and r2 (default "0... 350”).
3.
Press the encoder.
4.
Take no action for 15 seconds to exit the procedure in advance: the device will not
save the entered value.
For touch key models:
-
check that the keypad is not locked.
1.
Touch the SET key.
2.
Touch the UP or DOWN keys within 15s to set the value within
the limits r1 and r2 (default "0... 350”).
3.
Touch the SET key.
4.
Touch the ON/STANDBY key (or take no action for 15 s) to exit
the procedure in advance: the device will not save the entered
value.
4.4 Silencing the buzzer
For push encoder models:
-
rotate or press the encoder.
For touch key models:
-
touch a key.
