5.3.3.13Poweroff
When the power is switched on, a Wrong Poweroff
flag is set.
When the power is switched off when the engine is
not running, the Wrong Poweroff flag is reset.
When pressing the emergency stop, the programs of
the CCM and the UI keep on running, but the power
to the outputs is cut off, so the engine will stop
immediately.
When the power is switched off then, the Wrong
Poweroff flag is reset.
When the power is switched off while the engine is
running, the programs of the CCM and the UI will
keep on running and the CCM will stop in a controlled
manner (cooldown - stopping procedure), before it
will Powerdown and reset the Wrong Poweroff flag.
When the power is switched off as well as the
emergency stop is pressed, no power supply to the
CCM is left and the engine cannot be shut down
properly. The Wrong Poweroff flag is not reset.
When the power is then switched on again, the Wrong
Poweroff counter will add 1.
Executing a wrong poweroff can result in memory
damage.
5.3.3.14Powerdown
To save the batteries, the CCM and UI are equipped
with a Powerdown function.
When the compressor is not running and the
Automatic start is not activated, the CCM and UI will
go to Powerdown mode if there has not been any
action during the Powerdown time.
In Powerdown mode the CCM and UI will perform as
little as possible to reduce the power consumption.
The screen of the UI will therefore be shut down.
Local control mode
When a button is pressed on the UI, the CCM will
return to its previous status.
Remote control mode
When the compressor is in the Ready for Start status
and the Remote start button is pressed, the CCM will
come out of Powerdown and go directly to the
Permissive Start or Standby status. Pressing any other
Remote control button (except Remote ON), will only
result in deactivating the Powerdown, also when the
CCM is in any other status.
When the Remote ON input is not active, none of the
Remote inputs can deactivate the Powerdown.
When a button on the UI is pressed, the CCM will
come out of Powerdown.
When there has not been any action during three
minutes, the CCM will return to Powerdown.
PC control mode
When an action is performed via the PC, demanding
a response from the CCM or UI (Start signal,
changing settings, ...), the CCM will come out of
Powerdown.
When a button on the UI is pressed, the CCM will
come out of Powerdown as well.
When there has not been any action during three
minutes, the CCM will return to Powerdown.
5.3.3.15Air Discharge Temperature Control
(optional)
By changing the temperature of the cooling air going
through the aftercooler it is possible to heat the
discharge air to a certain setting.
This is done with a proportional valve controlled with
a PWM signal, and mounted on a cooler.
The Air Discharge Temperature Control becomes
active after the Warmup status, and stays active for as
long as the engine is running. The operation of the Air
Discharge Temperature Control depends on the Air
Discharge Temperature Control Parameter.
Air Discharge Temperature Control parameter
“Disable”
When the parameter is disable or disable lock, the PID
will regulate the Air Discharge Temperature to a
fixed value of 4°C to prevent freezing.
The CCM will run through the standard Warmup
procedure, with the valve closed.
