Curtain’s Opening Times:
The curtain’s opening times are associated with the activation of fan stages.
When the start temperature of a tunnel fan stage is reached, the curtain
opens according to the opening time that is associated with that stage.
Curtain is Fully Opened at Stage:
When the start temperature of this stage is reached, the curtain fully opens
and remains opened up until the temperature decreases below the stage's
stop temperature.
CURTAIN: BASED ON THE STATIC PRESSURE
PRINCIPLE OF OPERATION
Tunnel Ventilation’s Beginning:
The user defines a stage at which the tunnel ventilation mode starts. When
the start temperature of this stage is reached, the tunnel curtain opens
during the pre-opening delay. The stage's fans are then activated. Once
the curtain's pre-opening is done, the tunnel curtain becomes controlled by
the static pressure level as follows:
When the static pressure level exceeds the high pressure set point, the
curtain opens during the Open Time then stays still during the Off Time. This
process is repeated up until the static pressure level goes back to the desired
TIME
