Mode of operation

The MSE6-E2M is typically assembled behind a service unit combination.
It allows venting of the following system, both in the "Pressurise" state and in the "Shut-
off " state through a reverse flow (2 à 1). In the shut-off state, the reverse flow is consid­
erably reduced. For this reason, for more rapid venting, the MSE6-E2M should be in the
"Pressurise" status.
The key functions are:
Standby detection and automatic shut-off of the compressed air supply
The MSE6-E2M uses settable parameters to detect production down times of a pneumatic system. The
system is separated from the compressed air supply using the 2/2 shut-off valve, without venting the
subsequent system. This avoids additional air consumption through leakages. If production is to con­
tinue on the system, then it must be signaled to the MSE6-E2M. The shut-off valve opens and the sys­
tem is again supplied with compressed air.
Automatic shut-off of the compressed air supply can be activated and deactivated by the user. In the
deactivated status, the shut-off valve can be controlled directly by the PLC.
Pressure tightness testing
When in the shut-off state, the MSE6-E2M 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 serves as a measure
of the leakage existing in the system. If the parameterised limit value is exceeded, then the device will
output a diagnostic message.
Pressure recording
The MSE6-E2M continuously measures the output pressure, prepares the data and makes it available
cyclically.
To detect high operating pressures, the MSE6-E2M offers the option of parameterising limit values for
pressure. If the parameterised limit value is exceeded, then the device will output a diagnostic mes­
sage.
