3.1Preliminary notes

Operating Statuses:

- “on” state (the device is powered and is on: the regulators can be switched on)

- “stand-by” status (the device is powered but is switched off via software: the regulators are switched off; the possibility to manually switch on/switch off the cell light or auxiliary output depends on parameter u2)

- the “off” status (the device is not powered). Hereafter, with the word “start-up” means the passage from “stand-by” status to “on” status; the word “shutdown” means the passage from “on” status to “stand-by” status.

When the power is switched back on, the device displays the status that it was in at the time it was disconnected.

3.2Device switch-on/off in manual mode

Operating Statuses:

1.Make sure that the keyboard is not locked and that no procedure is in progress.

2.Hold the key down for 2 s: the LED will switch off/on. Using the digital inputs it is also possible to remotely switch on/off the device.

3.3The display

If parameter u9 is set at 0, the buzzer will not be activated.

4OPERATION DUE TO LOW OR HIGH RELATIVE HUMIDITY PERCENTAGE (ONLY IF PARAMETER

F0 IS ISET AT 5)

4.1Preliminary notes

During operation for low percentage of relative humidity, the evaporator ventilator will be switched on if the compressor is switched off (parameter F4 determines the amount of time it is switched off while parameter F5 determines the amount of time it is switched on).

During operation for a high percentage of relative humidity the evaporator fan is always on.

4.2Activation of operation for low or high percentage relative humidity in manual mode.

1.Make sure that the keyboard is not locked and that no procedure is in progress.

2.Hold the and keys down for 4 s: the display will show “rhL” (operation for low percentage of relative humidity) or “rhH” (operation for high percentage of relative humidity) for 10 sec.

To restore the normal display before the operation is complete:

3.Press a key.

Activation of the operation for a low or high percentage of relative humidity can be done using parameter F6.

If the parameter F0 is not set at 5, pressing the and keys will cause the display of the “- - -“ indication

for 1 s.

4.3Learning the type of operation in progress

1.Make sure no procedures are in progress

2.Press and release the and keys: the display

will show “rhL” (operation for low percentage of relative humidity) or “rhH” (operation for high percentage of relative humidity) for 10 sec.

To restore the normal display before the operation is complete:

3.Press a key.

If parameter F0 is not set at 5, pressing the and keys will cause:

-the display of the message “- - - -“ for 1 sec if the keyboard is not locked

-display of the label “Loc” for 1 sec if the keyboard is locked..

5	ENERGY SAVING

5.1Preliminary notes

Once the time you have set with parameter i10 has passed, without activations of the door micro switch input (after the cell temperature has reached the work set-point) the “energy saving” function is activated (until the input is activated again).

During function “Energy Saving” the working setpoint is increased of the temperature you have set with parameter r4 and the evaporator fan is turned on cyclically, on condition that parameter F0 has value 1 or 2 (parameter F13 sets the time the fan remains turned off and parameter F14 the time it remains turned on).

It is also possible to activate the “energy saving” function in remote mode through the digital inputs (with effect only on the compressor).

6 “HACCP” FUNCTION

6.1Preliminary notes

The device can memorise the following HACCP alarms:

-minimum temperature alarm (code “AL”)

-maximum temperature alarm (code “AH”)

-door micro switch input alarm (code “id”)

The device supplies the following information for every alarm:

-the critical value

-the duration of the alarm (from 1 min to 99 hours and 59 min, partial if the alarm is in progress).

Code	Critical value
AL	the minimum temperature of the cell during any
	alarm of this type
AH	the maximum temperature of the cell during any
	alarm of this type
iD	the maximum cell temperature during any alarm
	of this type; see also parameter i4

The device stored the minimum temperature alarm on condition that the temperature associated to the alarm is that of the cell (parameter A0 = 0).

if the device is switched off, no alarms will be stored.

The device updates the information regarding the the alarms provided the critical value of the new alarm is more critical than that stored or provided the information has already been displayed.

The “HACCP” LED provides information regarding the storage status of the alarms; see paragraph 10.1.
