cation port with the supervising system (through a serial interface, via

TTL, with MODBUS communication protocol) or with the program-

ming key; the port must not be used for two purposes at the same time.

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 place, the

humidity could condense inside; wait for about one hour before

applying power

• check that the power supply voltage, the frequency and the electric

operational power of the instrument correspond with those of the

local power supply

• disconnect the power supply before performing any type of mainte-

nance

• supply the probe with protection able to isolate it from 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

It is possible to select the utilities managed by the digital outputs (i.e.

relays K1, K2 and K3) among a series of four combinations (instrument

codes 1, 2, 3 and 4); a fifth combination (instrument code 0) allows to

set the utility managed by each output independently.

4 temperature airhole acoustics

regulation

To set the instrument code, see paragraph 4.1; to set the utility managed

by each output, see paragraph 4.2.

2.2 Management of the utilities

Temperature regulation.

The output activity mainly depends on the chamber temperature, the

work set-point and the parameter r0.

Airhole.

The output is activated in the following conditions:

• before the conclusion of the cooking timer count (of the time established

with the parameter c5), for the time established with parameter c6

• in manual mode, for the time established for parameter c7.

Steam injection.

The output activity depends mainly on parameter t0.

Through the multifunction input it is also possible to activate the output

in remote mode.

Alarm.

The output is activated during a temperature alarm.

Chamber light.

The output is activated in manual mode.

Cooking timer.

The output is activated during the cooking timer count.

Acoustics.

The output is activated in the following conditions:

• before the conclusion of the cooking timer count (of the time established

with the parameter c9), for the time established with parameter c4

• during an alarm or an error, with continuous contribution.

In spite of the fact that the instrument can manage the

7 utilities stated in this paragraph, there are 3 digital

outputs available. Make sure that the desired utility is

managed by the instrument (see paragraph 2.1).

3 USER INTERFACE

3.1 Preliminary considerations

The following functioning states exist:

• the “on” state (the instrument is powered and on: the regulators can

be on)

• the “stand-by” state (the instrument is powered but switched off via

software: the regulators are off)

• the “off” state (the instrument is not powered).

Successively, the term "switch-on" means the passage from the stand-by

state to the on state. The term "switch-off" means the passage from the

on state to the stand-by state.

When powered, the instrument re-proposes the state that it was in when

the power supply was disconnected.

3.2 Instrument switch-on/off

To pass from the stand-by state to the on state (and vice versa):

• make sure no procedure is in progress

• press for 1s.

3.3 The display

If the instrument is in the on state:

5 COOKING TIMER

5.1 Preliminary considerations

The cooking timer allows to start the reverse countdown of a time.

The count is shown in the lower part of the display; during the count

the “timer” LED is on and the timer output is activated.

Before conclusion of the count (of the time established with parameter c9)

the buzzer and the acoustic output are activated, for the time estab-

lished with parameter c4.

Before conclusion of the count (of the time established with parameter c5)

the airhole is activated, for the time established with parameter c6.

Using the multifunction input, it is also possible to start/interrupt the

cooking timer in remote mode.

6 STEAM INJECTION

6.1 Preliminary considerations

The functioning mode of the steam injection depends on parameter t0.

If the parameter t0 is set at 0, pressing the key causes the injection

of steam for the time established with parameter t2 or for the entire

duration that the key is pressed. The parameter t1 establishes the mini-

mum time that can pass between the two successive injections.

If the parameter t0 is set at 1, pressing the key will enable the

automatic injection of the steam (in cyclical mode: parameter t2 estab-

lishes the duration of the injector switch-on and parameter t1 estab-

lishes the duration of switch-off).

Using the multifunction input, it is also possible to cause the same effect

by pressing the key in remote mode.

If the steam injection is not managed by any digital output, pressing the

key will cause the display of the “no” indication for 1s in the lower

part of the display.

6.2 Quick setting of the parameter t2

in progress

• press and : the upper part of the display will show “t2”, the

lower part the corresponding value and the LED

will flash.

The parameter t2 can be set between 1 and 250 ds.

If steam injection is not managed by any digital output, the lower part

of the display will show “no” for 1s.

• press or within 15s

• press : the LED will switch-off, after which the instrument will

exit the procedure.

To exit the procedure in advance:

• do not operate for 15s (any modifications will be saved).

6.3 Activation of the injector in manual mode (only if

parameter t0 is set at 0)

• make sure that the instrument is in on state and that no procedure is

in progress

• press : the LED will switch-on and the injector will be acti-

vated, both for the time established with parameter t2 or for

the entire duration that the key is pressed.

The injector must not be deactivated in manual mode.

6.4 Enabling of automatic steam injection (only if pa-

rameter t0 is set at 1)

• make sure that the instrument is in on state and that no procedure is

in progress
