5.1 Machine use
DANGER:
for the machine, only operators correctly training and informed on the risks present can intervene on
the machine and only having fully read this use and maintenance handbook. the manufacturer
declines all responsibility for any damage to property and/or persons deriving from improper
interventions conducted by unqualified, untrained or unauthorised staff.
To use the machine, the following Individual Protection Devices are necessary:
5.1.1 Operation
Before starting the machine, it is necessary to ensure:
the locking screws are tight;
the electrical connections were correctly installed;
the coldroom door is closed to ensure the micro-door contact is closed.
5.1.2 Starting / Shutdown
When the machine is powered “OFF” is flashed alternating with the temperature of the cell.
To turn on (off) the machine it is necessary to press the "ON/OFF" button on the control panel for more than 5 seconds.
ATTENTION:
when the machine is powered the notice OFF is displayed on the control panel alternating the
temperature of the cell.
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
direct access (see
Paragraph 5.1.3.1
);
level 1
frequent use parameters
access without password (see
Paragraph 5.1.3.2
).
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 ST and SP can operate are reported in
Table 5.
Table 5 – Temperature value fields.
Minimum
Maximum
High temperature HBP
(Not planned for SV)
+2 +10
Medium temperature MBP
- 5
+ 5
Low temperature LBP
- 25
- 15
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
)
2.
Press SETPOINT: in this way the green SET led switches on and the display shows the SETPOINT value.
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);
2.
press UP and DOWN to display the desired menu on the display;
