5.3.3 A closer look at some operating procedure blocks
5.3.3.1 Process information
While the compressor is running, the operator can
take a brief look at all the incoming compressor and
engine data, by pressing the Process Info button.
This can be very useful for troubleshooting over the
phone.
5.3.3.2 System information
When in the Ready for Start status the System Info
button is pressed, all the system configuration settings
are displayed, such as: unit type, max. and min. set
pressure, active control mode, max. set RPM, battery
voltage.
From here the operator can enter the Options status,
where he can configure all the parameters he has
access to.
5.3.3.3 Options
Here the screen shows all the parameters the operator
can edit. With the arrow buttons, one scrolls to an
object, and toggles or selects it with the right function
button.
Selected values can be changed with the arrow
buttons, and the new value is confirmed with the OK
button.
At any time the operator can leave the Options status
and go to the Ready for Start status by pressing the
Return button.
5.3.3.4 Cranking procedure
When a start request is made, either by the operator or
automaticaly, all the compressor parameters are
checked.
When one of these parameters is out of its limits, the
operator is prompted to the Start failure status, and
must return to the Ready for Start status or to the
System Info status.
When all the parameters are within limits, the engine
starts cranking.
The starter motor runs for a preset time, and then the
engine rests for some time, before trying to start
again.
This cycle is repeated for a number of times.
When the engine does not start, the starting procedure
is ended, and the operator is prompted to the Start
Failure status after several failed attempts.
When during the cranking procedure the operator
presses the Stop button, a stopping procedure will be
executed, and the compressor will return to the Ready
for Start status.
5.3.3.5 Warming up
When the engine starts, the compressor enters the
Warmup status. This means the engine is going to run
idle until the engine coolant temperature has reached
a specific value.
If this coolant temperature setting is already reached,
there is no warmup, and loading can immediately
commence.
When after a specified maximum time the coolant
temperature setting is not reached, the compressor
will proceed anyway.
When starting manually, the operator can press the
Auto Load button. This will result in a skipping of the
Not Loaded status, and loading directly after the
Warmup status.
5.3.3.6 Pressure regulating system
A PID regulating system is implemented in the CCM
and becomes active in the Load/Unload status. This
PID regulates the air discharge pressure by adjusting
the engine RPM between RPM Min. and RPM Max.
When the air discharge pressure, which is monitored,
drops below the Reload pressure, the loading valve is
opened and the PID becomes active (load condition).
