CONTROLS AND SETTINGS
is from 0 to 150°C.
5) Minimum temperature (factory password): with this menu you can set the minimum temperature; the setting range is from
0 to -14°C.
6) Fan temperature (service password): with this menu you can adjust the temperature for activating the cooling fan; the
setting range is from 0 to 150°C. At the preset temperature the fan starts; hysteresis is fixed at 10°C.
7) Duration of the idle running cycle (service password): with this menu you can change the duration of the machine idle
cycle; the setting range is from 60 to 900 seconds.
8) Stop Empty Cycle (assistance password): using this menu you can change the duration of the empty operating cycle
following the voluntary stopping of the compressor (OFF button), the range of regulation goes from 30 to 240 seconds.
9) Automatic start (service password): this parameter enables the automatic start; if it is activated, the compressor will restart
automatically following an interruption of the electrical power supply.
10) Internal phase sequence (service password): this parameter enables the internal phase sequence control, or disenables
the internal control by activating the input without phases on the terminal block.
11) Language (no password required): this parameter allows you to change the language in which messages are displayed.
12) RS485 enable (no password required): this parameter is used to enable data transmission via RS485 and automatically
disenable transmission on RS232.
13) Set time and date (no password required): used for setting the current time and date.
14) PSI/BAR (no password required): for selecting the unit of measurement used to display the pressure.
15) Idle/Operating pressure set point (no password required): this parameter is used to set the pressure at which the compressor
must shut down.
16) Load/Operating differential set point (no password required): indicates the pressure at which the control unit enables
compressor restart.
17) Maximum pressure (service password): this parameter sets the maximum pressure value that can be reached, i.e. the
maximum value set in point 14.
18) Maximum pressure alarm (factory password): this parameter sets the maximum pressure value at which the control unit
trips an alarm and blocks compressor operation.
19) Remote Pressure (assistance password): enabling this parameter, the visualisation of the pressure and respective
alarms is maintained, but the control of the start of the compressor takes place using an external pressure switch linked to a
dedicated digital entry. In this event, it is necessary to pay attention that the setting of the external pressure switch falls within
the values imposed in points 15 and 16. In case of an anomaly, an alarm message will appear.
20) Start programme (service password): this menu allows you to programme the starts and stops of the compressor. Use
to select one of the five programmes available and press OK to enter the desired data (start time, stop time, and day of
the week).
To disactivate the programming, go to the menu and enter the same time of start and stop.
21) X1 progr. NC-NO (service password): allows you to invert the logic of the inputs of terminal block X1.
22) X7 progr. NC-NO (service password): allows you to invert the logic of the inputs of terminal block X7.
23) Motor therm. separate (service password): with the parameter ON, the thermal relays of the compressor and fan motors
are separated on two different inputs.
24) Temp. unit of measurement (no password required): for selecting the unit of measurement of the temperature (°C-°F).
25) Maximum starts per hour (service password): for selecting the maximum number of restarts per hour allowed. If this
value is exceeded, a signal is given.
