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 Display
To display the machine status follow the procedure below:
press and release SET: the display shows "SEt" or "AAL" if there are any alarms present;
1.
press UP or DOWN until the required parameter is displayed. The parameters can be:
2.
AAL alarms in progress (if any)
SEt setpoint
Pb1 cell temperature probe value
Pb2 evaporator temperature probe value
Pb3 probe 3 value (if present)
Out outlet relays status
InP digital inlets status
press SET to display the value;
3.
in the case of input or output alarms, press UP and DOWN to scroll the respective alarms present.
4.
press SET or ON/OFF (or wait for the 5 seconds timeout) to return to the list of status;
5.
press ON/OFF (or wait for the 5 seconds timeout) to return to the normal view.
6.
Code Level Descr.
List of -PPS passwords
PPA Parameters access password
Entering a pre-set password will give access to protected parameters
List of -rEG adjustment parameters
SEt 0 Setpoint
diF 1 Differential
temperature > setpoint + diff. -> adjustment On
temperature ≤ setpoint -> adjustment Off
List of -Pro probe parameters
CA1 1 Probe 1 calibration
CA2 1 Probe 2 calibration
CA3 1 Probe 3 calibration
List of -CPr compressor parameters
Ont 1 Compressor ON time in the
event of probe failure
OFt 1 Compressor OFF time in the
event of probe failure
dOn 1 Compressor activation delay
The time, starting from the switch on request, after which the
compressor is effectively activated.
In the event of network control in sequential mode, this represents the
activation delay from compressor to compressor
dOF 1 Minimum compressor OFF time
The time, starting from the moment of deactivation, for which it is not
possible to restart the compressor
dbi 1 Delay between switch on times
The time, starting from the moment of previous activation, for which
the compressor cannot be restarted.
Table 6 – Machine parameters.
The value assigned to this
parameter is added to (positive
value) or taken away from (negative
value) the temperature detected by
the probe
In the event of an adjustment probe
error, the compressor is enabled in
cyclical mode with set operation and
off times. In particular:
Ont=0: the compressor remains off
Ont>0 and OFt=0: the compressor
remains on
