Running Modes

STEP and RAMP

GreenFuture's latest control system offers two parameter running modes: STEP and RAMP.

The following section outlines the characteristics and differences between these two modes.

The STEP mode is a parameters running mode that regulates the stepwise alteration of parameters.

The specific performance of STEP mode is: when time point A is reached, the system initiates execution of the parameter instruction associated with time point A and rapidly achieves stability. This parameter continues to run continuously until the next time point with a different parameter instruction.

Example:

In STEP mode, the parameter settings shown in the right picture indicate:

• The system initiates the execution of the instruction for 0℃/0%RH/0μmol at 0:00 and continues until 4:00 after achieving stability.

• The system initiates the execution of the instruction for 11℃/60%RH/0μmol at 4:00 and continues until 8:00 after achieving stability.

• The system initiates the execution of the instruction for 18℃/70%RH/120μmol at 8:00 and continues until 11:00 after achieving stability.

• The system initiates the execution of the instruction for 28℃/50%RH/0μmol at 11:00 and continues until 15:00 after achieving stability.

• The system initiates the execution of the instruction for -10℃/0%RH/300μmol at 15:00 and continues until 24:00 after achieving stability, completing the running of 24 hours a day.

The RAMP mode is a running mode that regulates smooth gradient alteration of parameters.

Let param. a represent the settings at time point A and param. b represent the settings at time point B.

The specific performance of RAMP mode is: when time point A is reached, the system initiates a smooth and uniform control of parameters from parameter a to parameter b, until time point B is reached and the set value of parameter b is achieved, through the entire gradual process.

Example:

In RAMP mode, the parameter settings shown in the right picture indicate:

• During the time interval of 0:00~4:00, the system runs steadily at 15°C/0μmol.

• During the time interval of 4:00~6:00, the system undergoes a constant heating process from 15°C to 22°C, while the light intensity increases steadily from 0 to 100μmol.

• During the time interval of 6:00~8:00, the system runs steadily at 22°C/100μmol.

• During the time interval of 8:00~10:00, the system undergoes a constant heating process from 22°C to 28°C, while the light intensity increases steadily from 100 to 350μmol.

• During the time interval of 10:00-12:00, the system runs steadily at 28°C/350μmol.

• During the time interval of 12:00~14:00, the system undergoes a constant heating process from 28°C to 35°C, while the light intensity increases steadily from 350 to 400μmol.

• During the time interval of 14:00-15:00, the system runs steadily at 35°C/400μmol.

• During the time interval of 15:00~18:00, the system undergoes a constant cooling process from 35°C to 20°C, while the light intensity decreases steadily from 400 to 200μmol.

• During the time interval of 18:00-20:00, the system temperature runs steadily at 20°C, while the light intensity decreases steadily from 200 to 100μmol.

• During the time interval of 20:00~24:00, the system undergoes a constant cooling process from 20°C to 15°C, while the light intensity decreases steadily from 100 to 0μmol, completing the running of 24 hours a day.
