B 92.0 (3.622) 92.0 (3.622) 92,8 (3.653)
Warnings regarding installation:
• the thickness of the panel must not exceed 4.0 mm
(0.157 in)
• position the brackets as indicated in the drawing in this paragraph,
moderate the coupling torque
• make sure that the working conditions (temperature of use, humidity,
etc.) lie within the limits indicated in the technical data
• do not install the instrument in proximity of heat sources (heaters,
hot air pipes etc.) appliances with strong magnets (large diffusers
etc.), places subject to direct sunlight, rain, humidity, excessive dust,
mechanical vibrations or shocks
• in compliance with Safety Standards, the protection against any
contact with the electric parts must be ensured via correct installation
of the instrument. All parts that ensure protection must be fixed in a
way such that they cannot be removed without the aid of a tool.
1.3 Electric connection
With reference to the wiring diagram: the serial port is the port for
communication with the supervision system (via a serial interface, via
TTL, with MODBUS communication protocol) or using the programming
key. The port must not be used at the same time for two purposes.
Recommendations for the electric connection:
• do not operate on the terminal boards using electric or pneumatic
screwdrivers
• if the instrument has been taken from a cold place to a hot one, the humidity
could condense inside. Wait about one hour before applying power.
• make sure that the power supply voltage, frequency and operational
electric power correspond to those of the local power supply
• disconnect the power supply before performing any type of
maintenance
• equip the probes with a protection able to insulate them against any
contact with metal parts or use isolated probes
• do not use the instrument as a safety device
• for repairs and information regarding the instrument, contact the
Evco sales network.
2 PRELIMINARY CONSIDERATIONS
2.1 Preliminary considerations
The following types of cooking can be managed (successively also
called cooking phases):
• timed (see paragraph 4.3)
• core (see paragraph 4.4)
• steam (see paragraph 4.5)
• grill (see paragraph 4.6)
• continuous (see paragraph 4.7).
If the parameter r11 is set at 1, every cooking phase is preceded by a
pre-heating phase (see paragraph 4.2).
It is also possible to combine several cooking phases (i.e. plan that at
the conclusion of one cooking phase another different type is
automatically started) and memorise these combinations in the
programs (see chapter 11).
The utilities managed by the digital outputs (i.e. the K1 relays... K6) are
the following:
RELAY UTILTYMANAGED
K1 temperature regulation
K2 grill
K3 can be set (airhole default)
K4 steam injection
K5 fan
K6 can be set (default reversal of the direction of the fan)
To set the utility managed by the relay K3 and relay K6, see
paragraph 5.1.
2.2
Management of the utilities
Temperature regulation.
The output activity will mainly depend on the temperature of the
chamber (chamber probe), the work set-point of the phase in progress
and the parameter r0.
The output can be on during the pre-heating phase and during any
cooking phase.
Grill.
The output is switched-on in a cyclical way (the parameter c1 establishes
the cycle time; the parameter c11 establishes the duration of switch-on
of the grill, intended as a percentage of the time established with
parameter c1).
The output can also be switched-on in manual mode.
The output can only be switched-on during the grill cooking phase.
Airhole.
The output is switched-on in the following conditions:
•before the conclusion of the steam cooking phase (the time established
with parameter c5), for the time established with parameter c6
• in manual mode, for the time established with parameter c7 (both
during the pre-heating phases and during any cooking phase).
Steam injection.
The output is switched-on in the following conditions:
• during the steam cooking phase, according to the method established
with parameter t0
• in manual mode, for the time established with parameter t2 or for
the entire duration of the manual action (both during the pre-heating
phase and during any cooking phase).
Via the multifunction input it is also possible to switch the output on in
remote mode.
Fan.
The output can be on during the continuous mode during the pre-
heating phase and during any cooking phase.
If the parameter F2 is set at 1, the fan output and the inversion output
of the direction of fan movement will be switched-on in cyclical mode
(the parameter F4 establishes the duration of every direction of
movement. The parameter F3 establishes the time between switch-off
of one output and the switch-on of another).
It is also possible to reverse the direction of movement of the fan in
manual mode.
Chamber light.
The output is switched-on in manual mode.
Via the multifunction input it is also possible to switch the output on in
remote mode.
The output can be on during the pre-heating phase and during any
cooking phase.
Steam generator.
The output is switched-on in manual mode.
The output can be on during the pre-heating phase and during any
cooking phase.
Alarm.
The output is switched-on during a temperature alarm.
The output can be on during the pre-heating phase and during any
cooking phase.
Acoustics.
The output is switched-on in the following conditions:
• at the conclusion of the pre-heating phase and at the conclusion of
the core cooking phase for the time established with parameter c4
• before conclusion of the timed cooking phase, the steam cooking
phase and the grill cooking phase (with time established using
parameter c9), for the time established with parameter c4
• during an alarm or an error, with continuous contribution (during
the heating phase or during any cooking phase).
On/Stand by.
The output is switched-on during the “on” status (see paragraph 3.1).
The output can be on during the pre-heating phase and during any
cooking phase.
In spite of the fact that the instrument can manage the 10
utilities stated in this paragraph, there are 6 digital outputs
available. Make sure that the utility desired is managed
by the instrument (see paragraph 2.1).

USER INTERFACE
3.1 Preliminary considerations
The following functioning states exist:
• the “on” status (the instrument is powered and on: the outputs can
be switched on)
• the “programmed switch-on” status (the instrument is powered but
is switched-off via software: the outputs are off and programmed
switch-on of the instrument is envisioned)
• the “stand-by” status (the instrument is powered but is switched-off
via software: the outputs are off and programmed switch-on of the
instrument is not envisioned)
• the “off” status (the instrument is not powered).
Successively, the term “switch-on” means that the passage from the
stand-by status to the on status; the term “switch-off” means the passage
from the on status to the stand-by status.
When the instrument is powered it re-proposes the status in which it
found itself at the time when the power supply was disconnected.
3.2
Selecting the functioning state
To pass from the stand-by status to the on status (and vice versa):
• make sure no procedure is in progress
• press
for 1 s:
To pass from the programmed switch-on status to the on status:
• make sure no procedure is in progress
• press
for 1 s:
To pass from the on status to the programmed switch-on status:
• make sure no procedure is in progress
• press
and for 1 s:
To pass from the stand-by status to the programmed switch-on status
(and vice versa):
• make sure no procedure is in progress
• press
and for 1 s:
Via the on/stand-by input it is also possible to pass from the on status
(or from the programmed switch-on status) to the stand-by status in
remote mode.
To pass from the on status (or the programmed switch-on status) to
the stand-by status in remote mode:
• activate the on/stand-by input (the instrument remains in the
stand-by status for the entire duration of the input activation).
The successive deactivation always causes passage to the on status. If
the on/stand-by status is active, it will not be allowed to pass from the
stand-by status to the on status (or to the programmed switch-on status)
by pressing the keys.
3.3
The display
If the instrument is on:
• the upper part of the display will show the quantity established with
parameter P5:
- if P5 = 0, the display will show the chamber temperature
- if P5 = 1, the display will show the work set-point of the phase in
progress
