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.
- 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.

: an internal
test will start up.
The test normally takes a few seconds; when it is finished the display will switch off.
3.
Configure the device as shown in the section
Setting configuration parameters
.
Recommended configuration parameters for first-time use:

4.2
Unlocking the keypad
Touch a key for 1 s: the display will show the label “
UnL
”.
4.3
Quick setting:
- steam injection duration (if t00 = 0 and t13 = 0, default)
- cycle time for steam injection (if t00 = 0 and t13 = 1)
- number of steam injection automatic cycles (if t00 = 0 and t13 = 2)
- percentage of steam injection maximum duration (if t00 = 0 and t13 = 3)
- cooking timer duration (if t00 = 1)
For push encoder models
