DURING OPERATION

The doors must be closed during operation
and may be opened for short periods only.
Regularly carry out following checks:
1. That the regulating valve (RV) is correctly adjusted, i.e.
starts decreasing the engine speed when reaching the
preset working pressure in the receiver.
2. Check the air outlet temperature of the compressor
element.
3. Check the engine oil pressure, the coolant tempera-
ture and all lamps for normal readings.
4. Avoid the engine running out of fuel. Nevertheless, if
this happens, fill the fuel tank and prime the fuel sys-
tem to speed up starting (see section ).
When the engine is running, the air outlet
valves (ball valves) must always be put in
fully opened or fully closed position.

OPERATIONS OVERVIEW

It is possible to control the compressor locally with the
Control Box, remotely with the remote switch inputs
located on the back of the Control Box, or with software
running on a PC with a CAN interface (PC Control Mode).
The way one ends up in each status can differ from how
the Control Box is controlled, but the function of each
status stays the same.
When reading this document, mind the difference between
a status and a procedure. A status is a state in the Control
Box's operation. A procedure is an action executed by the
Control Box.
Example: The Stopping procedure is executed in the
Stopping status, the Start Failure status and the Shutdown
status.
