5 USER INTERFACE
5.1 Foreword
The following operating status exist:
- the “off” status (the device is not powered)
- the “stand-by” status (the device is powered and is off)
- the “on” status (the device is powered, is on and is in stand-by for the start-up of an operating cycle)
- the “run” status (the device is powered, is on and an operating cycle is in progress).
Hereon, the term "device switch-on" means the passage from the "stand-by" status to the "on" status. the term
"switch-off" means passage from the "on" status to the "stand-by" status.
If a power cut occurs during the "stand-by" status or during the "on" status, the device will re-propose the same
status when the power supply is restored.
If a power cut occurs during the "run" status, the device will operate as follows when this is restored:
- if a temperature-controlled blast chilling or deep freezing operation was in progress, these will be started again
from the beginning
- if a time-controlled blast chilling or deep freezing operation was in progress, these will be started again from
the moment the power supply was cut-off
- if storage was in progress, this will be re-proposed.
5.2 Switching the device on/off
Operate as follows:
1. Make sure that the keyboard is not locked and that no procedure is in progress.
2. Hold the ON/STAND-BY key down for 2 s: the LED will switch on/off.
5.3 The display
All displays are off during the "off" status and during the "stand-by" status.
During the "on" state:
- the 1 digit display is off.
- the 3 digit display:
- will display the blast chilling end temperature if a temperature-controlled blast chilling cycle has been
selected or the deep freezing end temperature if a temperature-controlled deep freezing cycle has been
selected.
- will display the blast chilling duration if a temperature-controlled blast chilling cycle has been selected or
the deep freezing duration if a temperature-controlled deep freezing cycle has been selected.
- the 4 digit display:
- will display the work set-point during blast chilling if temperature-controlled blast chilling has been
selected or the work set-point during deep freezing if temperature-controlled deep-freezing has been
selected.
- will be off if time-controlled blast chilling or time-controlled deep freezing has been selected.
During the "run" state:
- the 1 digit display shows the program number if there is one in progress.
- the 3 digit display:
- will show the temperature detected by the needle probe if a temperature-controlled blast chilling or deep
freezing cycle is in progress
- will display the residual blast chilling time if time-controlled blast chilling is in progress or the residual
deep freezing time if time-controlled deep freezing is in progress
