TYPE OF SERVICE
Automatic operation
•
Compressor operation is regulated by the pressure transducer, which stops the machine when the maximum pressure is
reached and restarts it when the pressure has returned to the minimum setting value.
The machine stop is delayed type; that is, it does not coincide precisely with the reaching of P max, but after a defined interval
of time during which there is no air intake.
•
The factory setting is 180 seconds, but we recommend checking that the number of starts per hour is NOT greater than the
maximum recommended number of 12. If the number is greater, it is preferable to increase the idle running time (see the section
“Modifiable parameters” point 7).
MODIFIABLE PARAMETERS
Pressing the OK button with the machine OFF takes you to the menu of operating parameters. In certain cases a
password is required in order to access the modifications. Use the
buttons to scroll the menu.
0) Control unit ID (service password): selects the identification number of the control unit; if several compressors are connected
to the same RS485 line, multiple IDs can be selected.
1) Maintenance – Pre-alarm hours (service password) : each working hour of the machine is counted down automatically;
when the counter reaches 0, the control unit trips a Maintenance Alarm.
Use the XX buttons to scroll the items of the menu:
1. General maintenance:
hours remaining
2. Air filter change:

6. Idle hours:

7. Total working hours:
displays the total working hours
The count preceded by the (-) sign indicates the number of hours that have elapsed since the last maintenance alarm.
The
buttons can be used to set a new value (in this way overriding the previous alarm).
2) Alarm history (no password required): with this menu you can view the last 100 alarms.
3) Pre-alarm temperature (factory password): on this menu you can set the temperature differential (“delta”, expressed in °C)
with respect to the maximum alarm temperature; the value can be set between 1 and 20.
Example: If the maximum temperature is 120°C and the dif ferential value is 10°C, the maximum temperature pre-alarm is
tripped at 110°C.
4) Maximum temperature (factory password): with this menu you can set the maximum temperature allowed; the setting range
