1.1 Safety
1.1.1 General safety information
Warning
Risk of injury
If there is an error (e.g. fieldbus interruption, PLC failure, no voltage) on the MSE6-E2M,
then the shut-off valve switches to the initial position (pressurise) if the system para
meters are set accordingly. If the valve was previously closed, the system is pressurized.
If the system was vented, pressurisation takes place suddenly.
 Use appropriate measures to ensure that unintentional pressurisation of the system
is not possible.
Warning
Risk of injury due to residual pressure
When the input pressure is being switched off (e.g. during a venting procedure), a resid
ual pressure of P2 1 bar (P2 0,1 MPa) can remain at the output of the MSE6-E2M.
 Use appropriate measures to ensure that the residual pressure does not result in a
hazard.

2Overview
2.1 Design
The MSE6-E2M is an intelligent pneumatic service unit, which is equipped with measurement, control
and diagnostic functions and which supports energy-efficient operation of pneumatic systems. The
module is typically assembled behind a service unit combination.
The MSE6-E2M consists of the main components: shut-off valve, flow sensor, pressure sensor and bus
node. The fieldbus interface allows complete integration into a higher-order controller, e.g. a system or
machine controller. As an alternative to integration into a higher-order controller, the MSE6-E2M can
also be operated using an external operator unit (CPX-MMI) or a PC.

2.1.2 Mode of operation
Machine/sys
tem
Fig. 2.2 Typical installation position (as an example at the bus node CPX-FB33)
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 à1). 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.

2 Overview
12 Festo – MSE6-E2M-IN-EN – 2017-07c – English
Flow recording
The MSE6-E2M continuously records the flow, prepares the data and makes it available cyclically.
To detect high flow rates, the MSE6-E2M offers the option of parameterising limit values for the flow. If
the parameterised limit value is exceeded, then the device will output a diagnostic message.
Consumption recording
The MSE6-E2M determines the compressed air consumption by recording the system flow rate. The
user has the option of using appropriate signaling to record the compressed air consumption over a
specific period of time.
2.2 Commissioning, diagnostics and operational functions
The system reaction of the MSE6-E2M can be adapted to the relevant application. The MSE6-E2M
provides extensive functions for commissioning, diagnosis and operation.
Commissioning and operational functions
The MSE6-E2M is supplied from the factory with preset parameters.
The behaviour of the MSE6-E2M can be adapted to the respective requirements through parameterisa
tion. The following behaviour can be influenced, for example, by accessing the internal parameters:
– The diagnostic behaviour by enabling maskable diagnostic messages
– Specification of the units and the measuring interval
– Setting of limit values
– The operating method of the diagnostic memory.
Caution
A different parameterisation will result in different characteristics.
 In particular, check which settings are required when replacing the MSE6-E2M.
 Ensure that the settings can be restored (e.g. in the start-up phase by the higher-or
der PLC/IPC).
Basic information on the different parameters can be found in Chapter 7. A detailed de
scription of the parameters can be found in Chapter 7 of the system description for the
energy efficiency module (èMSE6-E2M-SY-…).

2 Overview
Festo – MSE6-E2M-IN-EN – 2017-07c – English 13
Diagnostic functions
Extensive diagnostic information can be accessed, depending on the fieldbus used.
Diagnostic information Brief description
Status bits Common diagnostic messages (global error messages) are displayed by
means of 8 internal inputs (8 status bits).
I/O diagnostic
interface
With fieldbuses that do not possess extensive diagnostic functions, the
diagnostic information of the MSE6-E2M is available via the I/O diagnostic
interface. The I/O diagnostic interface enables bus-independent access to
diagnostic information, data and parameters via internal digital I/Os
(16 inputs and 16 outputs).
Diagnostic memory Errors which occur during operation are entered in a diagnostic memory.
The first or the last 40 entries are saved, as well as the respective time
measured from the moment the power supply was switched on.
Fieldbus-specific dia
gnostic functions
Special diagnostic functions or communication services are available,
depending on the fieldbus used.

3.3 Combination with MS6 modules
Note
Observe the notes regarding installation and commissioning of MS6 modules in the
corresponding documentation.
Note
Observe the maximum permissible number of ten individual modules for the overall
combination. The MSE6-E2M counts as a double module here.
Note
When supplementing MS6 modules, only use the MS6-WPG wall mounting and the
MS6-MV-EX module connector.
Note
Observe the notes regarding the procedure for left and/or right-hand side assembly of
maintenance modules, as described in the assembly instructions for the MS6-WPG wall
mounting set.
Note
Please note that when using a MS6-SV-D, a MS6-WPG wall mounting set may not be
mounted on the right-hand side due to a mechanical conflict with the sensor cables.
Alternatively, an MS6-FRM-FRZ distributor block can be inserted.
Note
Please note that in the case of a larger device configuration, a longer FE connection is
required.
For the left and/or right-hand side supplement of the MSE6-E2M with MS6 modules, proceed as follows:
1. Use an MS6-WPG wall mounting set for MS6 individual modules or, in the case of pre-assembled
MS6 combinations, replace the MS6 wall brackets with the wall mounting set.
2. For MS6 individual modules use MS6-MV-EX module connectors or, in the case of pre-assembled
MS6 combinations, replace all of the standard module connectors with these module connectors.
For a left-hand supplement, proceed as follows:
3. Remove the left-hand pneumatic base plate of the MS6 module or MS6 module combination re
spectively and assemble the left-hand pneumatic base plate of the MSE6-E2M at this point.
4. Connect the earth terminal on the left-hand pneumatic base plate with low impedance (short cable
with large cross section) to the left end plate of the electrical interlinking module of the MSE6-E2M.

3 Mounting and installation
18 Festo – MSE6-E2M-IN-EN – 2017-07c – English
For a right-hand supplement, proceed as follows:
5. Remove the right-hand pneumatic base plate of the MS6 module or MS6 module combination re
spectively and assemble the right-hand pneumatic base plate of the MSE6-E2M at this point.
When mounted correctly, a low-impedance connection must exist between the earth terminals of the
left and right-hand pneumatic base plate.
 With low-impedance connections, make sure that the earth terminal at the left end plate of the
electrical interlinking module on the MSE6-E2M and the earth terminal at the power supply connec
tion have the same potential and that there are no compensating currents. If necessary, the pre-
assembled electrical connection of the MSE6-E2M must be replaced by a longer, electrically equival
ent connection.
By following this approach you will prevent interference from electromagnetic sources and ensure
electromagnetic compatibility in accordance with EMC directives.
