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 (resistances,

hot air pipes, etc.), appliances with strong magnets (large diffusers,

etc.), places subject to direct sunlight, rain, humidity, excessive dust,

mechanical vibrations or jerks

• in compliance with Safety Standards, protection against any contact

with electrical parts must be assured via correct installation of the

instrument. All parts that ensure protection must be fixed in a way 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 the

communication with the supervising system (through a serial inter-

face, via TTL, with MODBUS communication protocol) or with the

programming 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

• 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.

1.4 Functions associated with the digital outputs

It is possible to set the utility managed by each digital output (i.e. relays

K1 ... K6).

OUTPUT PREDEFINED FUNCTION

K1 Temperature regulation

The output activity mainly depends on the work set-point

and the parameter r0

K2 Cooking timer

The output is activated during the cooking timer count

K3 Acoustics

The output is activated in the following conditions:

• 10 s before the conclusion of the cooking timer count, for

the time established with parameter c4

• during alarms and errors, with continuous contribution

K4 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 estab-

lished with parameter c6

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

K5 Steam injection

The output activity depends mainly on parameter t0

Through the multifunction input it is also possible to acti-

vate the output in remote mode

K6 On/stand-by input

The output is activated during the on state

To set the utility managed by each output, see paragraph 3.1.

2 USER INTERFACE

2.1 Preliminary considerations

The following functioning states exist:

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

• the “programmed switch-on” state (the instrument is powered but

switched off via software: the regulators are off and programmed

switch-on of the instrument is envisioned)

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

software: the regulators are off and programmed switch-on of the

instrument is not envisioned)

• 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.

2.2 Selecting the functioning state

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

• make sure no procedure is in progress

• press for 1s.

To pass from the programmed switch-on state to the on state:

• make sure no procedure is in progress

• press for 1s.

To pass from the on state to the programmed switch-on state:

• make sure no procedure is in progress

• press and for 1s.

To pass from the stand-by state to the programmed switch-on state (and

vice versa):

• make sure no procedure is in progress

• press and for 1s.

Through the on/stand-by input it is also possible to pass from the on

state to the stand-by state in remote mode.

To pass from the on to the stand-by state in remote mode:

• activate the on/stand-by input (the instrument remains in the stand-by

state for the entire duration of input activation).

The activation of the on/stand-by input causes the passage from the on

state or from the programmed switch-on state to the stand-by state: the

successive deactivation always causes the passage to the on state. If the on/

stand/by input is active, it will not be allowed to pass from the stand-by state

to the on state (or programmed switch-on state) by pressing the keys.

2.3 The display

If the instrument is in the on state:

• 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

• the lower part of the display will show the quantity established with

parameter P6:

- if P6 = 0, the display will show the chamber temperature

- if P6 = 1, the display will show the work set-point (in this case the “set”

LED will be on)

- if P6 = 2, the display will show the value of the cooking timer or its

count if the timer is active (in this case the “timer” LED will be on); the

value of the cooking timer is displayed in the hours:minutes format.

activated for 3s.

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.

• check probe integrity

• check the instrument-probe connection

• check the chamber temperature

Main consequences:

• the temperature regulation output will be deactivated

• the acoustics output and the buzzer output will be acti-

vated

rtc the lower part of the display: clock error

Remedies:

• set the day and real time again

Main consequences:

• the programmed switch-on will not be available

• the acoustics output and the buzzer output will be activated

When the cause of the alarm disappears the instrument restores normal

functioning, except for clock error (code “rtc”) that requires the day

and real time to be set.

outputs), 6-pole connector (serial port). Temperature of use: from 0 to 55 °C (from 32 to 131 °F, 10 ... 90%

relative humidity without condensate).

Power supply: 115 ... 230 VAC, 50/60 Hz, 5 VA (approx) or 24 VAC,

50/60 Hz.

Keeping the clock data in a power-cut: 24 h with battery

charged.

Battery charging time: 2 min without interruptions (the battery is

charged by the instrument power supply).

Alarm buzzer: incorporated.

measurement inputs: 1 (chamber probe) for J/K thermocouple or

Pt 100 2 wire probe (according to the model).

Digital inputs: 2 inputs:

• on/stand-by input in high voltage (230 VAC) with

configurable polarity

• multifunction input, for NO/NC contact (potential-

free contact, 5 V 1 mA).

Range of measurement: from -99 to 800 °C (from -99 to 999 °F) for J thermocouple, from -99 to 999 °C (from -99 to 999 °F) for K thermocouple, from -99 to 650 °C (from -99 to 999 °F) for Pt 100 probe.
