3.4.2 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.
During operation
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 temperature and display of control box.
4 Avoid the engine running out of fuel. Nevertheless, if this happens, fill the fuel tank and prime
the fuel system to speed up starting (see section 3.4.4 Specific start procedure).
3.4.3 Battery switch
The compressor is equipped with a battery switch.
When the compressor is not in use this switch must always be in the “OFF” position.
It is not allowed to use this switch as an emergency switch or for stopping the compressor. It will
cause damage in the control unit when using this switch for stopping.
Always first shut off the control unit and wait until the display is dark before switching the battery
switch to position “OFF”.
When the engine is running, the air outlet valves (ball valves) must always be
put in a fully opened or fully closed position.
The doors must be closed during operation and may be opened for short periods
for inspection and adjustments only.
