9.2 Utilities that can be activated in parameter programming
• Pressing the steam cycle and hot air cycle buttons(lev. A and lev.B) or pressing Phase and Start button
(on lev. B and lev. C), all the output relays are sequentially activated and on the time display it will be
displayed the activated relay with the message do1, do2, . (dox=RLx on the EWD). See APPENDIX H.
o The steam cycle or phase button acts as main switch: if it is released, the test stops.
o Each time the hot air cycle or start button is pressed, the next relay is activated and remains
activated till the next pressure of the hot air cycle or start button.
o If the hot air cycle or start button is kept pressed, the relays are sequentially activated.
• Pressing the time buttons, the time will be displayed
• Pressing the utility button, on the time display a 4-characters message will be displayed while on the
little display will be shown a number with the following meanings
Big display Meaning of the number on the little display
ntc
PCB temperature
Prb1
First meat probe temperature (lev. A)
Prb2
Second meat probe temperature (lev. A)
Prb3
Third meat probe temperature (lev. A)
Prb4
Fourth meat probe temperature (lev. A)
Prb5
Fifth meat probe temperature (lev. A)
Prb6
Sixth meat probe temperature (lev. A)
CEL1
First cavity temperature
CEL2
Second cavity temperature
boL1
First boiler probe
boL2
Second boiler probe
byP
Bypass probe
Prb
Single-point meat probe (lev. B)
HuM
KS contactor is activated for 15 s and the lambda probe is fed and after a while the
cavity humidity will be displayed
If one of the probes is detecting the same temperature of the ntc probe (PCB temperature), the
meanings are the following:
1) Probe in short circuit
2) Probe not connected (for example Prb on a lev. A oven)
3) Probe at the same temperature of the ntc probe
• Pressing the temperature button a lamp test is activated
• If the word “HOLD” in the utility section is green it means the door microswitch is in closed position
• If the word “HACCP” in the utility section is green it means the cavity flap microswitch is closed
• If the led “open door” is switched on in parameter programming mode, it means that the safety level
probe of the boiler is detecting water
• If the led “scale alarm” is switched on in parameter programming mode, it means that the working level
probe of the boiler is detecting water
10 Selection of the language for the recipe menu (lev. A)
It is possible to select a language for the menu of the recipes. To select the language, set parameter LanG
to the correct value for the desired language (see the relevant parameter list).
