MEASUREMENTS AND INSTALLATION
Measurements in mm (inches). 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 SPEC-
IFICATIONS 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.
The controller is operated mainly by P10 (default "controller with two independent regulators").

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.

4.
Disconnect the device from the mains.
5.
Make the electrical connection as shown in the section ELECTRICAL CONNECTION, with-
out powering up the device.

When 30 s have elapsed without the keys being pressed, the display will show the “Loc” label
and the keypad will automatically lock.
4.2
Unlocking the keypad
Touch a key for 1 s: the display will show the label “UnL”.
4.3
Quick setting:
- of setpoints (if P9 = 1 or 3)
- beater switch on/off times (if P9 = 2 or 3)
Check that the keypad is not locked.
1.
Touch the SET key: the display will show the label “SP1”.
2.
Touch the UP or DOWN key within 15 s to set the load 1 setpoint
value within the limits r1 and r2 (default “-50... 50”).
3.
Touch the SET key: the display will show the label “SP2”.
4.
Touch the UP or DOWN key within 15 s to set the load 2 setpoint
value within the limits r12 and r13 (default “-50... 50”).
5.
Touch the SET key: the display will show the label “SP3”.
6.
Touch the UP or DOWN key within 15 s to set the beater setpoint
value within the limits r16 and r17 (default “-50... 50”).
7.
Touch the SET key: the display will show the label “t0”.
8.

5.3
Controller for ice cream batch freezers (P10 = 2)
The batch freezing cycle consists of 4 phases:
-
heating
-
cooking
-
cooling
-
conservation.

The compressor remains off.
Plate heaters operation.
Beater operation.
End of phase.
At the end of the phase the buzzer emits 10 beeps 1 s long.
If there is a power failure during the phase, it starts back up again from the beginning.
