Schedule
Start and

Pressures
If the schedule and pressure band
functions are enabled, different
start and stop pressures can be
specified for each of daily
scheduled operating periods.
It is recommended to maintain a
pressure differential of at least
1.50 bar between the start and
stop pressure settings here.
Start and stop discharge
air pressures for each of
the scheduled daily
operating periods.
User Service
Warning: The compressor set’s built-in schedule function allows it to be switched on and off automatically
according to the preset timer(s). This feature does not include provision for any alarm or annunciation that
the unit is about to start or stop. The schedule function should therefore NOT be used unless the person
conducting a business or undertaking involving the management or control of the plant has first implemented
at least the following risk control recommendations:
a) Do not operate the compressor with any of its maintenance access panels open or removed.
b) Before opening or removing any of its maintenance access panels or performing any maintenance
work on the compressor or connected pneumatic system: Switch off the unit; isolate and tag-out the
power supply; carefully release the residual air pressure from the internal piping and any external air
receiver tank and connected piping; and close the air outlet valve.
Note: Reducing the differential between the start and stop pressures will increase the on and off cycling
frequency of the compressor modules. This may cause the permissible number of air-end drive motor starts
per hour to be exceeded, which will trigger a shutdown alarm for the affected motor(s). Refer to the
Instruction Manual for guidance about the pressure differential and recommended air receiver tank volume.
2.6 System Operation Menu
The system operation menu is accessed via the system menu. Logging-in with the user password allows full
access to view the parameters; logging-in with the service password is necessary to edit most of the set
values. The system operation menu screen is shown in Figure 2.6.
