Standby detection and automatic pressure reduction
The energy efficiency module detects downtime of a pneumatic system when correspondingly parame-
terised. If the parameterised flow rate limit value is continuously undershot during the parameterised
delay period, when the automatic function is activated, controller auto-user and controller auto-enable
logic 1, the supply air is blocked until the parameterised standby setpoint pressure value is reached.
The output pressure is then adjusted to this value. This prevents unnecessary exhausting of the
system and enables leakage detection via an analysis of the pressure drop. A control signal can
be used to switch back over from standby pressure regulation to normal pressure regulation. When
the automatic function is deactivated, the shut-off valve and the pressure regulator can be directly
controlled by the machine controller.
Regulation of the compressed air supply
The energy efficiency module regulates the compressed air supply to the set pressure setpoint value.
This can be done in manual mode by the setting from the controller. In automatic mode, regulation it is
regulated by the parameterised target pressure values.
Testing pressure-tightness
The energy efficiency module continuously measures the pressure change in the parameterised time
interval and monitors this value to ensure it is not exceeded in the blocking status. The measured
pressure change serves as a measure of the leakage existing in the downstream system.
Pressure recording
The energy efficiency module continuously measures the output pressure, prepares the data and
makes it available cyclically. To detect operating pressures that are too high or too low, the energy
efficiency module offers the option of parameterising critical limits for pressure. If the parameterised
limit value is exceeded, the energy efficiency module will output a diagnostic message.
The status of monitoring to ensure the critical limit is not exceeded is indicated via an input bit and via
the P2 LED on the module.
Flow recording
The energy efficiency module continuously measures the flow rate, prepares the data and makes it
available cyclically. To detect excessive flow rates, the energy efficiency module offers the option of
parameterising the upper critical limit for the flow rate. If the parameterised limit value is exceeded,
the energy efficiency module will output a diagnostic message.
Consumption recording
The energy efficiency module determines the compressed air consumption by recording the system
flow rate. With the aid of output data, the consumption measurement can be switched on and off and
the consumption value can be reset.
