5.1.3. Parameter variation procedure
Functioning of the Blocksystem series SF, series P and series SV is regulated by the parameters set in the memory of the electronic
central unit by the manufacturer (see Table 6). We recommend you do not change these values unless strictly necessary and in
any case always contact the enabled staff. As well as for functioning, the parameters are sub-divided by safety/accessibility level:
level 0 SETPOINT parameters
level 1 frequent use parameters
The parameters can be changed on the keyboard, via the LAN (Master/Slave) network or using the Supervision network.
5.1.3.1. Coldroom temperature regulation
The fields of the temperature values for which the Blocksystem series SF,series P and series SV can operate are reported in
Table 5.
High temperature HBP
(Not planned for SV)
Medium temperature MBP
Low temperature LBP
It is possible to access the regulation set point of the temperature in a direct manner to display or change the value. In relation to
this, implement the following procedure:
1. Press and release SETPOINT: the display shows "SET" (if there are alarms ongoing the procedure is slightly different; see
Paragraph 5.1.4)
Press SETPOINT: in this way the green SET led switches on and the display shows the SETPOINT value.
2.
3. Press UP and DOWN to set the new value.
4. Press SETPOINT or ON/OFF (or wait for the 5 second timeout) to confirm the value; in this way the SET led switches off and
the display shows "SET".
5. Press ON/OFF (or wait for the 5 second timeout) to return to normal view.
5.1.3.2. Change level 1 parameters
To change the parameters corresponding to level 1, use the following procedure:
1. press SET for 5 seconds until the displays shows "reg" (regulation parameters);
press UP and DOWN to display the desired menu on the display;
2.
3. press SET to access the menu; in this way the code appears of the first parameter of the menu selected;
4. press UP and DOWN to display the desired parameter;
5. press SET to display the parameter value;
6. press UP and DOWN to set the desired value;
7. press SET to confirm the value and return to the parameters list; or press ON/OFF to confirm the value and return to menu
list;
8. to pass to the parameters list to the menu list press ON/OFF;
9. to exit the change parameters procedure press ON/OFF again.
If you don't press one of the keys for more than 15 seconds, the possible value display is stored in the relative parameter and you
are forced to exit the change parameters procedure.
5.1.4. Machine status view
To view the machine status, use the following procedure:
press and release SET: the display shows "SEt" or "AAL" if alarms are ongoing;
1.
2. press UP and DOWN to view the relevant status. The statuses could be:
AAL alarms ongoing (if present)
SEt setpoint
Pb1 coldroom temperature probe value
Pb2 evaporator temperature probe value
Pb3 probe value 3 (if present)
Out relay outputs status
InP digital inputs status
3. press SET to display the value;
4. in the case of alarms status, outputs status, inputs status, press UP and DOWN to scroll respectively the ongoing alarms, the
outputs and the inputs;
5. press SET or ON/OFF (or wait for the 5 second timeout) to return to the list of statuses;
6. press ON/OFF (or wait for the 5 second timeout) to return to normal view.
