Standby detection and automatic blocking of the compressed air supply
The energy efficiency module uses modifiable parameters to detect production downtime of a pneu-
matic system. The system is disconnected from the compressed air supply by the 2/2 shut-off valve,
without exhausting the downstream system. This avoids additional air consumption by leakages. If
production is to continue on the system, then it must be signaled to the energy efficiency module. The
shut-off valve opens and the system is again supplied with compressed air.
Automatic blocking of the compressed air supply can be activated and deactivated by the user. In both
states, the shut-off valve can be controlled directly by the PLC.
Testing pressure-tightness
When in the blocked state, the energy efficiency module measures the pressure curve over time.
Even in well-serviced systems, the pressure falls continuously due to leakages. The fewer leakages
the system has, the slower the pressure drop will be. The measured pressure change is indicative
of leakages in the system. If the parameterised limit value is exceeded, the device will output a
diagnostic message.
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, 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.
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.
