temperature. For further information see the technical
manual).
Buzzer silencing
Press the 1 button. Besides silencing the buzzer, the
alarm relay is reset, while the alarm code remains
memorised until the cause of the alarm has been
removed.
Enabling of Auxiliary Output:
Press the 6 button to activate/deactivate the lights or
any other auxiliary output.
Continuous Cycle
To activate the 'continuous cycle' functioning press
the 2 button for al least 5 seconds (compressor
activated for the time selected with the 'cc, parameter
= duration of 'continuous cycle).
So as to deactivated the continuous cycle functioning,
press the 2 button again for 5 seconds.
3. PARAMETERS
The parameters have been organised into two levels:
• FIRST LEVEL: frequent parameters. They are
indicated with F in the table and the password is
not necessary to gain access to them. To modify
them operate as follows:
1. press button 1 for more than 5 seconds (in case
of alarm, first silence the buzzer);
2. the display shows the code of the first
parameter to be modified.
3. To modify the parameters see the "parameter
modification" section.
• SECOND LEVEL: configuration parameters.
They are indicated with C in the table and it is
necessary
to
insert
modification, as indicated here below:
1. press simultaneously buttons 1 and SEL for
more the 5 seconds;
2. the display shows 00;
3. press button 5 and 6 until 22 (password) is
displayed;
4. confirm by pressing SEL button;
5. the display shows the code of the first
parameter to be modified.
To modify the parameters see following section,
"parameter modification".
Parameter modification:
To modify a parameter operate as follows:
1. press 5 and/or 6 until the parameter to be modified
is displayed (refer to the parameters table);
2. press the SEL button to visualise the value
associated to the parameter;
3. modify its value by pressing 5 and/or 6 buttons
until the desired value is displayed;
4. press the SEL button to temporarily confirm the
the
password
for
newly set value and to go back to the parameter
code display;
5. repeat all operation from the point "press 5 and /
or 6" to modify other parameters values;
New Set Values Store:
Press button 1to store all new set values and exit the
procedure.
To exit without modifying parameters: do not press
any button for at least 60 seconds (TIME OUT exit).
Warning: if button 1 is not pressed after modifying
operations, all effected modifications will be lost.
4. ALARM AND SIGNALS
FLASHING LED: actuator set delay
Insertion of the relative function is delayed for a period
while awaiting an external signal or while help up by
another process still in progress.
TEMPERATURE FLASHING: door switch broken
or door open for a period longer than the d8
parameter
Close the door or check the door switch.
E0 FLASHING: evaporator probe error
Probe not compatible with the equipment; probe cable
interrupted or short circuit.
Faulty sensor: disconnect the probe from the
instrument and measure the resistance (NTC: 0°C=27
K Ohms).
E1 FLASHING: evaporator probe error
Probe not compatible with the equipment; probe cable
interrupted or short circuit.
Faulty sensor: disconnect the probe from the
instrument and measure the resistance (NTC:
0°C=27Ω).
IA FLASHING: alarm from digital input
any
Check 'Multi-function' inputs and parameters A4 and
A5.
dA FLASHING: delayed alarm from digital input
Check 'Multi-function' inputs and parameters A4, A5
and A7.
LO
FLASHING:
(temperature lower than SET-AL-A0)
Check parameters AL, Ad and A0. The alarm will
cease as soon as the temperature returns within the
limits selected.
HI
FLASHING:
(temperature higher than SET+AH+A0)
Check parameters AH, Ad and A0. The alarm will
cease as soon as the temperature returns within the
limits selected.
EA, EB, EE: data acquisition error. RESET
procedure
In order to restore normal working conditions, reset
the default value of the parameters, using this
