Code Level Descr.
ddL 1 Display during the defrosting phase
0 = normal display (as set from the ddd par.)
1 = freezes the temperature value displayed at the start of defrosting until
the end of defrosting and the reaching of the setpoint
2 = "dF" until the end of defrosting and the reaching of the setpoint
The ddL parameter can be controlled only if the standard display
(ddd par.) includes the adjustment probe (probe 1 or network probe)
1 Defrosting display block timeout
Ldd
The time, starting from the end of defrosting (end of dripping phase),after
which the normal display is in any case restored
dro 1 °C or °F selection
0 = °C
1 = °F
This selection only affects temperature measurements. The values of the
parameters concerning temperature maintain their current values and
therefore, they must be varied manually to adapt them to the Fahrenheit
scale.
-CnF
List of
1 Keyboard lock
LOC
0 = keyboards disabled
(*)
1 = main terminal keyboard enabled
2 = secondary terminal keyboard enabled
3 = keyboards enabled (the first to request a service has precedence until
completion)
rEL 1 Software release
A read-only value that identifies the software version
-LAn
List of
1 Supervision network address (for Master only)
dEA
The address to be set on each master must take into account the number of
slaves present in the LAN network preceding it: "dEA"="dEA[previous
master]"+"L01[previous master]"+1
The Supervision network address for a Slave is "dEA[master]"+"L00")
(*) Note : To release the keypad, hold down "SET" and "ON/OFF" together for at least 5 seconds.
(**) Note : The "LAn" network parameter only serves in the event of MASTER/SLAVE or REMOTE CONTROL
operation

ALARM SIGNALS

In the event of an alarm, the card normally activates the following:
•
The relevant alarm code is shown on the display. In particular, the control alternates the
alarm code and the temperature that is normally shown on the display; if there is more than
one alarm, they are displayed in succession, alternated with the temperature
•
The alarm LED is switched on
•
The alarm relay is triggered.
For some alarms and signals, the LED and/or relay are not triggered. The table below gives a
detailed description for each alarm and the relevant actions undertaken.
Pressing any button will deactivate the relay (if triggered) and the LED will blink, while the alarm code
will remain on the display. The LED will switch off and the alarm code will disappear only when the
cause behind it has ceased. The alarm codes are listed in the table below:
Code Description/Control
displayed
E1 cold room probe temperature error
if a probe is used for adjustment, the compressor
will be activated cyclically and defrosting cycles will
be disabled;
if a balanced network probe is enabled, adjustment
will continue, bypassing the malfunctioning probe
E2 End defrostin probe g error
defrosting will end due to timeout
E3 3 rd probe error (condenser temperature)
the associated controls are disabled
3 rd probe error (2nd evaporator temperature)
defrosting will end due to timeout
