Switching on/off
When the machine is energised, the display will read OFF and show the coldroom temperature
alternately. To switch the Blocksystem on (off), hold down the “ON/OFF” key on the front of the machine
for more than 5 seconds.
7. 3 Coldroom temperature adjustment
The temperature ranges within which the Blocksystem can operate are as follows:
Minimum Maximum
High Temperature (HBP) +2 +10
Medium Temperature
(MBP)
-5 +5
Low Temperature (LBP) -25 -15
The temperature adjustment setpoint can be accessed directly for display or adjustment purposes.
•Press and release SETPOINT: the display will read “SEt” (the procedure is slightly different if there
are alarms in progress; see the machine status display paragraph)
•Press SETPOINT: the green SET LED will switch on and the Setpoint value will be displayed
•Press UP or DOWN to set the new value
•Press SETPOINT or ON/OFF (or wait for the 5-second timeout) to confirm the value (the SET LED
will switch off and the display will read “SEt”)
•Press ON/OFF (or wait for the 5-second timeout) to return to the normal display mode
7. 4 How to vary parameters
Blocksystem operation is governed by parameters that have been stored in the memory of the electronic
control unit by the manufacturer (see the parameters table). These factory settings should not be varied
unless strictly necessary, and in all cases such operations are only to be carried out by qualified staff.
Parameters are not only divided by function, they are also divided according to their security/accessibility
levels:
Level 0 Setpoint parameters direct access (see paragraph 7.3)
Level 1 frequently used parameters access without password (see paragraph 7.5)
Level 2 configuration parameters access with password (see paragraph 7.7)
Parameters can be varied as follows:
From the keyboard
Via LAN network (Master/Slave)
Via Supervision network
7. 5 How to vary level 1 parameters
Hold down SET for 5 seconds until the display reads “reg” (adjustment parameters)
Press UP or DOWN until the required menu appears on the display
Press SET to access the menu; the code number for the first parameter in the selected menu will
appear
Press UP or DOWN until the required parameter appears
Press SET to view the value of the parameter
Press UP or DOWN to set the required value

ADVANCED ELECTRONIC CARD PROGRAMMING FOR BLOCKSYSTEM
1. Level 2 programming
The procedure for editing level 2 parameters is protected by a password and can be carried out in the
following manner: enter the programming mode by holding down the “set” key for at least 7 seconds
until the display reads “reg”, which corresponds to the adjustment parameters directory, then proceed
as follows:
Press the “down” key (the display will read “PPS”)
Press the “set” key (the display will read “PPA”)
Press the “set” key again (the display will read “0”)
Press the “up” key until the display reads 22 (the level 2 password)
Press the “set” key to confirm the password
At this point, using the “up” and “down” keys, you can access all of the electronic card parameters
shown in the annexed programming chart.
Once you have edited the required parameters, press the “ON/OFF” key twice until the display shows
the cold room temperature (or wait for 15 seconds without pressing any keys); this way the edited
parameters will be stored to the memory.
CAUTION!
THE FOLLOWING SECTION EXPLAINS THE NECESSARY PROCEDURE IN THE EVENT THAT
PARAMETERS ARE EDITED WITHOUT FOLLOWING ANY CRITERIA OR THAT THE CARD SETTINGS
ARE LOST. IN ANY CASE, WE ADVISE THAT YOU FOLLOW THESE STEPS ONLY AFTER THE
APPROVAL OF A RIVACOLD TECHNICAL ENGINEER.

RIVC000001 Pag. 15 REV. 00 11/10/10
UK
2. Restoring the factory settings
CAUTION: the following procedure will restore all factory settings for the electronic card. We advise
that you only do this if strictly necessary and in any case, that you are assisted by a technical engineer
from Rivacold.
Cut off the power to the Blocksystem.
Press the “set” and “down” keys at the same time, then switch the Blocksystem on again while holding
down these keys.
Release the keys when the display reads “–3”.
At this point, the electronic card will re-start and its parameters will have returned to those set in the
factory. The display will read “Um” for 1 second; it will then show the temperature read by the cold
room probe.
PLEASE NOTE: THIS OPERATION RESTORES THE FACTORY SETTINGS FOR A MEDIUM-
TEMPERATURE MACHINE APPLICATION (-5/+5°C) WITH “HOT GAS” DEFROSTING.
IF YOU ARE USING AN APPLICATION OTHER THAN “MEDIUM TEMPERATURE” AND/OR A
DIFFERENT TYPE OF DEFROSTING (NOT “HOT GAS”), YOU MUST FOLLOW THE INSTRUCTIONS
IN THE FOLLOWING SECTION, AND REFER TO THE “CPP PARAMETER PROGRAMMING CHART”.
3. Rapid programming according to the application required
Level 2 programming contains a parameter known as “CPP” (to be found in the “cnf” directory) which
is used for the rapid programming of parameters according to application and defrosting types (see
following chart).

Press the “up” or “down” keys until you reach the “CnF” directory
Press the “set” key (the LOC parameter will appear)
Press the “up” key until you reach the “CPP” parameter
Press the “set” key (the number 0 will appear)
Press the “up” key until you reach the number corresponding to the required program
Then press the “set” key to confirm.
8. 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:

9.EMERGENCY SYSTEM
PLEASE NOTE: A specialist technical engineer must only perform the operations described here below.
If the electronic control unit breaks down or presents operating anomalies and it is impossible to replace
it immediately, there is an EMERGENCY SYSTEM that can be used to maintain the unit in operation until
it can be replaced.
To use this system, proceed as follows:
1. Cut off power to the Blocksystem
2. Remove all jumpers between the L terminals and the common contacts of the card relays (terminals
25-28-33-36-38)
3. As shown in the diagram, connect a thermostat between the L terminal, the NO terminals (terminals
32,37) and the NC terminal (terminal 34) of the compressor, defrosting and fan relays (COMP, DEF
and FAN)
4. Fit a jumper between the L terminal and the NO terminal of the ON/OFF relay (terminal 26
supplying power to the crankcase heaters, door and waste, where fitted).
5. Connect the Blocksystem back to the mains power, setting the thermostat to the required
temperature.
6. PLEASE NOTE: This connection can only be used momentarily. Contact your dealer as soon as
possible to replace the malfunctioning card.
7. PLEASE NOTE: Defrosting will be cut out for the entire emergency phase and for this reason, we
recommend that cold room door opening be kept to a minimum.
8. When fitting the new control unit, restore all of the connections described in points 2,3,4 and 5.
