5.2 Functions
Overview
– Pressure regulation and blocking function (energy efficiency function)
– Automatic blocking and subsequent regulation to the standby target pressure with a pro-
longed reduced flow rate
– User-controlled blocking and pressure regulation
– Parameterisable target pressure rise limitation
9Festo — MSE6-C2M — 2019-03
Page 10
Product overview
– Recording and processing of measurement data
– Outlet pressure P2
– Pressure change (for pressure tightness testing)
– Flow rate
– Air consumption
– Limit monitoring
– Pressure, lower and upper critical limit
– Pressure change, upper critical limit
– Flow rate, upper critical limit value
– Electrical I/Os

– Parameterisable special functions
– Fieldbus connection
– e.g. PROFINET connection CPX-M-FB34
Standby detection and automatic pressure reduction
The product detects downtimes of a pneumatic system upon corresponding parameterisation. If the
parameterised flow rate critical limit is continuously not reached 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 target pressure value is reached. The outlet
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 product regulates the compressed air supply to the set pressure setpoint. This can be done in
manual mode by the setting from the controller. In automatic mode, regulation takes place via the
parameterised target pressure values. Prerequisite: operating pressure P1 ³ target pressure + 1bar.
Pressure tightness testing
The product 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 product continuously measures the outlet pressure, prepares the data and makes it available cyclically. To detect operating pressures that are too high or too low, the product offers the option of
parameterising critical limits for pressure. If the parameterised critical limit is exceeded, the product
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.

Product overview
Flow recording
The product continuously records the flow rate, prepares the data and makes it available cyclically. To
detect excessive flow rates, the product offers the option of parameterising the upper critical limit for
the flow rate. If the parameterised critical limit is exceeded, the product will output a diagnostic message.
Consumption recording
The product 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.
Operational functions
The behaviour of the product can be influenced by accessing the internal parameters, e.g.:
– Diagnostic behaviour by enabling maskable diagnostic messages
– Specification of the units and the measuring interval
– Setting of critical limits
The product is delivered with pre-set parameters. Information on parameterisation è 9 Parameter.

Product overview
5.3 Electrical system configuration
The maximum permissible current load of the system supply for the MSE6-C2M-…-M (with CPX extension) is 6A.
The product is equipped with a field bus node. Input and output data as well as parameters and diagnostic information can be transferred to the higher-level controller via the field bus node. Power is
supplied via a separate supply port.
The MSE6-C2M-…-M product variant has a CPX-Extension Series 1 interface to which certain products
with a CPX-Extension Series 2 interface can be connected:
– 1 energy efficiency module MSE6-D2M or
– up to a maximum of 3 digital and/or analogue CPX input and output modules
The following CPX I/O modules are permitted:
– CPX-4DE (4 digital inputs)
– CPX-8DE (8 digital inputs)
– CPX-4DA (4 digital outputs)

6.1 Safety
The product is equipped with a pneumatically-piloted proportional-pressure regulator and a downstream shut-off valve. The shut-off valve is pneumatically piloted and is open in a normal position.
When input pressure P1 is applied, the product automatically regulates the outlet pressure in the following cases to the last parameterised power-on target pressure (default setting 10 bar):
– Switch on of operating voltage until the connection is successfully made with the high-order con-
troller.
– Interruption of the network communication with correspondingly set system parameters
– Stopping of the higher-order controller (see manufacturer's specifications), e.g. in the case of
transmission of control programs, parameters, configuration data.
In the basic state, the module regulates the output pressure to the preset Power-On target pressure
when the shut-off valve is open. In the event of undervoltage in the operating voltage or the load

voltage, the electronic pressure regulation is inactive when the shut-off valve is open. If prolonged,
this can lead to an undefined drop in the outlet pressure.

the following sequence:
1. Switch on the power supply of the MSE6-C2M-…(-M).
2. Switch on the power supply for the controller.
Addressing the network
The controller uses the following for addressing:
– Device names
– IP addresses (optional MAC-ID)
– Input and output addresses (I/O addresses)
Basic addressing rules

7 Measuring and control function
The following sections provide an overview of the individual measurement and control functions of the
product and present their setting options and their influencing variables.
Individual functions and their behaviour can be controlled using the outputs and/or parameters.
Measurement and status signals are available as input values. Diagnostic information is made available as a combination of the error number and their respective channel allocation.
For the following designations of inputs and outputs and parameters, m is the module number that is
based on the address position of the product in the CPX overall system and has the fixed value m=0.
7.1 Flow rate
Input signal
The measured flow rate is prepared according to the set parameters flow rate (Pm.8.2-8.3) and "Unit
flow rate" (Pm.8.6-8.7) and “Unit flow rate standard” and provided as an input signal (Em.0).
Critical limit monitoring
A comparator is used to compare the measured flow rate value with the parameter “Upper critical limit
flow rate” (Pm.11-12). When the time set in the parameter "Monitor critical limits" startup (Pm.7) has
elapsed and critical limit monitoring is activated (Pm.0.6), the appropriate error/diagnostic message is
output if a critical limit is exceeded.
Monitoring of parameters
The parameters flow rate (Pm.8.2-8.3), flow standard (Pm.8.6-8.7), upper limit flow (Pm.11-12) and
monitoring critical limit startup(Pm.7) are checked for permissible values when entered. In case of
error, the appropriate error message is output if parameterisation error monitoring is activated
(Pm.0.7).

7.2 Consumption
Input signals
The consumption measurement is based on the prepared flow rate value. Depending on the unit consumption (Pm.8.4-8.5) and flow standard (Pm.8.6-8.7) parameters, the consumption values are processed in 2 independent channels and provided as input signals in 16-bit and 32-bit data format:
– Consumption V0 (16 bit): input Em.1 and selectable inputs Em.5 and/or Em.6
– Consumption V0 (32 bit): selectable inputs Em.5-6
– Consumption V1 (16 Bit): selectable inputs Em.5 and/or Em.6
– Consumption V1 (32 bit): selectable inputs Em.5-6
There is also a continuous consumption measurement which, after a certain, unit-dependent consumption, generates a logic 1 measurement impulse with a duration of 100ms. For the consumption
units l and m³, the consumption value is 200l. For the consumption unit scf, the consumption value is
10scf.
The measuring pulse is provided at the input Measuring pulse consumption VC (Em.3.7). In addition,
the signal is output at electrical output 0 if the parameter Select DO0 signal has the value
Pm.28.3=1.
If there is a change to the parameter values “Unit flow rate” or “Flow rate standard”, the measured
consumption values are reset to the value “0”.
If there is a change to the parameter value “Unit consumption”, the current measured consumption
values are saved and converted to the new consumption unit.
User-controlled consumption measurement
2-channel consumption measurement is controlled using two data bits in the output word for module
control (Am.0). With the outputs Consumption V0 Run (Am.0.12) or Consumption V1 Run (Am.0.14),

Monitoring of upper pressure critical limit
A comparator is used to compare the measured pressure value with the parameter “Upper pressure
critical limit” (Pm.13-14). When the time set in the parameter "Monitor critical limits" startup (Pm.7)
has elapsed and critical limit monitoring is activated (Pm.0.6), the appropriate error/diagnostic message is output if a critical limit is exceeded.
Monitoring of parameters
The parameters unit pressure (Pm.8.0-8.1), lower critical limit pressure P2 (Pm.25-26), upper critical
limit pressure (Pm.13-14) and monitoring critical limit startup (Pm.0.7) are checked for permissible
values during input. In the event of an error, the corresponding error message is output if parameterisation error monitoring is activated (Pm.0.7).
Sensor monitoring
If there is a sensor error, the appropriate error message, which cannot be deactivated, is output.

7.4 Pressure change
7.4.1 Method of measurement
The pressure change DP2 is determined cyclically at intervals of the parameterisable pressure change
sample time DT. When calculating the pressure change, the difference between the current measured
pressure value and the measured pressure value DT, based on the pressure change sample time P2, is
calculated:
DP2=P2(t)–P2(t-DT); t=current measurement time.
The start of the measuring cycle to calculate the pressure change is automatically synchronised with
the activation signal of the shut-off valve. The current pressure change value DP2 remains constant up
to the next measuring time. Each time the parameter "Unit" (Pm.8) is written, a re-synchronisation follows.

7.4.2 Function structure
Input signal
The measured pressure change value DP2 is prepared according to the set parameters “Unit pressure”
(Pm.8.0-8.1) and “Pressure change sample time” (Pm.10) and can be shown as a selectable input signal in Em.5 and/or Em.6.
Critical limit monitoring
If the shut-off valve is in the blocking state, the amount of the measured pressure change is compared
with the parameter “Upper critical limit pressure change”(Pm.15-16) using a comparator. If critical
limit monitoring is activated (Pm.0.6), the appropriate error/diagnostic message is output if the critical limit is exceeded.
Monitoring of parameters
The parameters “Unit Pressure” (Pm.8.0-8.1), “Pressure change sample time” (Pm.0) and “Upper limit
pressure change” (Pm.15-16) are checked on entry for permitted values. In the event of an error, the
corresponding error message is output if parameterisation error monitoring is activated (Pm.0.7).

7.5 Pressure regulation and blocking function
7.5.1 Overview
The pressure regulation and blocking function function determines the current module status by evaluating pressure and flow measured values. The desired outlet pressure P2 is set by controlling the
pressure regulator and the shut-off valve accordingly.
Depending on the setting, the module works in user-controlled or automatic pressure regulation and
blocking function.
In the user-controlled pressure regulation and blocking function, the shut-off valve is controlled directly. One of the various fixed values or a variable value can be set as the target pressure.
29Festo — MSE6-C2M — 2019-03
Page 30
Measuring and control function
In automatic pressure regulation and blocking function, the target pressure is set to Auto Normal in
the basic state. If the flow rate falls below the set flow rate critical limit for the specified period of time,
the automatic pressure regulation and blocking function first switches to shut-off mode if activated
accordingly. After a pressure drop to the target pressure Auto Standby, the function then switches to
pressure regulation mode with the target pressure Auto Standby.
In this state, a corresponding control signal is required to change to pressure regulation mode with
the target pressure Auto Normal. Depending on the selection, this control signal must be generated by
an output control bit or one of the two electrical inputs.
Status and status signals of the pressure regulation and blocking function are displayed in an input
word for user-side sequence monitoring.
In both user-controlled and automatic pressure regulation and blocking function, there is a moduleinternal target pressure value limitation to a range between 2.5…and 10 bar and a parameterisable
target pressure rise limitation.
The entire structure of the pressure regulation and blocking function with all sub-functions, operands
(inputs, outputs, parameters) and error/diagnostic messages is described in the subchapter Function
Structure.
7.5.2 User-controlled pressure regulation and blocking function (USER)
The user-controlled pressure regulation and blocking function is activated if the output control AutoUser (Am.0.1) has the value 0 (not active).
In this state, the shut-off valve can then be switched by the user to the status "Pressurise" or "Block"
with the output Controller Shut-off valve (Am.0.0). The switching status of the shut-off valve is signalled in input Em.3.0.
For the target pressure for the pressure regulating valve, the target pressure user selection
(Am.0.3-0.4) output can be used to select between the following values and functions:
– Power-On target pressure, adjustable to 10 bar or 6 bar with the parameter Power-On target pres-
sure (Pm.28.2)
– Minimum target pressure (2.5 bar)
– Deactivated electronic pressure regulation
– Variable target pressure setting via output target pressure user (Am.2)
With Power-On and any further user-side increase in the target pressure value, the rise slope is limited
to the value set with the target pressure rise limitation parameter (Pm.28.4-28.6).
The time diagram shows the module behaviour after Power-On and subsequent variable target pressure adjustment to 2 different values.

7.5.3 Automatic pressure regulation and blocking function (AUTO)
The automatic pressure regulation and blocking function is activated when the output control AutoUser (Am.0.1) has the value 1 (active).
The automatic pressure regulation and blocking function starts with each activation in module state
AUTO_NORMAL (Em.3.8-3.11 =8). In this state, the shut-off valve is open and the pressure regulating
valve regulates to the parameter value Target pressure Auto Normal (Pm.21-22). At the same time, the
Q_low-Timerfunction starts monitoring to check whether the flow rate value falls below the parameter
value Auto-controller flow rate critical limit (Pm.19-20). If the value falls below the critical limit, a
change to the state AUTO_WAIT(Em.3.8-3.11 =9) takes place and the duration of the state is monitored by the Q_low-Timer. If the critical limit underrun exceeds the time limit set with the parameter
Auto-controller delay time (Q_low-Timer has elapsed), a change to the state AUTO_HOLDoccurs
(Em.3.8-3.11 =10). In this state, if the shut-off valve is still open, the setpoint pressure is set to Auto
Normal. If the flow rate reaches or exceeds the Auto-controller flow rate critical limit during the states
AUTO_NORMAL, AUTO_WAITandAUTO_HOLD, the flow rate immediately returns to the state
AUTO_NORMAL(Em.3.8-3.11 =8).
To switch the target pressure from Auto Normal to Auto Standby in the stateAUTO_HOLD, the output
control Auto-Enable (Am.0.5 =1) must be activated. This can be done permanently or by the user
depending on the system, e.g. if automatic switching is not permitted due to the situation.
31Festo — MSE6-C2M — 2019-03
Page 32
Measuring and control function
If Auto-Enable is activated (Am.0.5 =1) in the output control stateAUTO_HOLD, the shut-off valve
switches to the shut-off state and the new module state is AUTO_SHUTOFF(Em.3.8-3.11 =11). As
soon as the pressure P2 has dropped to the target pressure Auto Standby, the module status changes
to AUTO_STANDBY(Em.3.8-3.11 =12). The shut-off valve is open again and the pressure regulating
valve regulates to the target pressure Auto Standby.
A change from the module state AUTO_STANDBYwith target pressure Auto Standby to the module
state AUTO_NORMAL with target pressure Auto Normal is only possible by resetting the Q_low-Timers.
While the pressure increases, the function is in module AUTO_RISEstate (Em.3.8-3.11 =13). In this
state, the slope of the pressure rise is limited to the value set with the target pressure rise limitation
parameter (Pm.28.4-28.6).
The following figure gives an overview of the relevant measurement, control and status signals of the
automatic pressure regulation and blocking function by means of an exemplary flow rate curve. The
output Q_low-Timer-Reset(Am.0.2) is set as the signal source for resetting theQ_low-Timers.

Q_low-Timer
The function Q_low-Timer continuously compares the prepared measured flow rate value with the
parameter Auto-controller flow rate critical limit. If the critical limits are not reached, Q_low-Timer is
started. The Q_low-Timer enters status UP if the flow rate critical limit is not reached for longer than
the time parameterised in the parameter Auto-controller delay time (Pm.17-18).
The timer status is displayed in the input status Q_low-Timer (Em.3.4-3.5) and can have the following
values:
– 0=RES: the timer is reset and not started.
35Festo — MSE6-C2M — 2019-03
Page 36
Measuring and control function
– 1=RUN: the timer was started and is running.
The timer has not yet exceeded the parameter value Auto-controller delay time (Pm.17-18).
– 2=UP: the Timer has expired.
The timer has exceeded the parameter value Auto-controller delay time (Pm.17-18).
The Q_low-Timer is reset in the following cases:
– In module state AUTO_WAIT(Em.3.8-11=9) and
In module state AUTO_HOLD(Em.3.8-11=10) when Auto-controller flow rate critical limit is
exceeded (Pm.19-20)
– by a reset control signal (1=active). The signal can be selected with the parameter Q_low-Timer-
Reset selection (Pm.28.0-28.1):
– Output Q_low-Timer-Reset (Am.0.2)
– Electrical input DI0
– Electrical input DI1
– Logic operation: electrical input DI0 OR output Q_low-Timer-Reset(Am.0.2)
Module status
The module status results from the status or status of sub-functions of the pressure regulation and
blocking function and is displayed in input (Em.3.8-3.11).
The individual module states are described in chapter Function states.
Shut-off valve
Depending on the setting of output control Auto-User (Am.0.1), the shut-off valve is controlled either
by the user or by the partial function Auto-controller shut-off valve.
The switching status of the shut-off valve is determined by the input Status shut-off valve (Em.3.0):
The shut-off valve switching cycle number is provided in different types and data formats:
– 16-bit or 32-bit input value via selectable inputs Em.5 and/or Em.6
– 16 bit parameter value (Pm.31-32)
Pressure regulator
Depending on the setting of output control Auto-User (Am.0.1), the target pressure for the pressure
regulator is determined as follows:
– By the target pressure value set by the user
– By the target pressure value specified by the Auto target pressure sub-function.
Before being passed on to the pressure regulator, the setpoint value is limited to values between 2.5
and…10.0bar within the module. The rise is limited to the set parameter value when the target pressure is increased.
Monitoring of parameters
The parameters "Pressure unit" (Pm.8.0-8.1), "Flow rate unit" (Pm.8.2-8.3), "Flow rate standard"
(Pm.8.6-8.7), "Auto-controller flow rate critical limit" (Pm.19-20) are checked for permissible values
when entered. In case of error, the appropriate error message is generated if parameterisation error
monitoring is activated (Pm0.7).
Actuator supply monitoring
This function is used to monitor the actuator supply for undervoltage. In the event of an error, the corresponding error message is generated with activated monitoring (Pm.0.2).

7.6 Electrical inputs
The "Electrical inputs" function is equipped with 2 digital inputs, which can also be used to reset the
Q_low-Timers of the pressure regulation and blocking functions with appropriate parameterisation.
Input signals
The signals of the electrical inputs 0 and 1 are processed according to the parameters debounce time
DI (Pm.27.4-27.5) and signal extension time DI (Pm.27.2-27.3). The times are valid for both channels.
The activation of the signal extension is set channel by channel with the parameters Signal extension
channel DI0 (Pm.27.0) and Signal extension channel DI1 (Pm.27.1). The input signals are provided as
electrical input DI0 (Em.3.2) and electrical input DI1 (Em.3.3).
Status indicators
The status of the electrical inputs is indicated channel by channel by status LEDs. When the LED is lit,
a logic 1 is present at the input, when the LED is not lit, a logic 0.
Sensor supply
The sensor supply voltage 24VSEN is provided at the connections for the electrical inputs. The sensor
supply voltage 24VSEN is internally protected against short-circuit/overload. The parameter Behaviour after short-circuit/overload sensor supply (Pm.27.6) is used to set whether the sensor supply is
switched on again after short-circuit/overload end or remains switched off. If the diagnosis with the
parameter Monitoring short-circuit/overload sensor supply (Pm.0.0) is activated, the corresponding
error message is generated in case of overload.

Measuring and control function
7.7 Electrical outputs
The electrical outputs function is equipped with 2 digital outputs, one of which can be used alternatively for the output of the consumption measurement pulse.
Output signals
The electrical outputs are controlled via the outputs module control Am.0.6 and Am.0.7 during basic
setting. Alternatively, the consumption measurement pulse VC can be output at output DO0 if the DO0
Signal Selection (Pm.28.3) parameter is set accordingly.
The electrical outputs have an internal short-circuit/overload protection. The parameter Behaviour
after short-circuit/overload outputs (Pm.27.7) defines whether the electrical outputs remain switched
off after short-circuit/overload end or are switched on again automatically.
Status indicators
The status of the electrical outputs is displayed channel by channel by means of a status LED. When
the LED is lit, the output provides a logic 1. If the LED is not lit, the output provides a logic 0.
Monitoring of short circuit/overload
The electrical outputs are monitored channel by channel for short-circuit/overload. The error status is
signalled in input module status (Em.3.14 for output 0, Em.3.15 for output 1). In addition, with activated diagnostics (setting with parameter Pm.0.1), a group error message is generated for outputs 0
and 1 if at least 1 channel is overloaded.
Actuator supply monitoring
The actuator supply is monitored for undervoltage. In the event of an error, the corresponding error
message is generated with activated monitoring (Pm.0.2).

8.3 Selectable input data function
The input and output words of all I/O data are shown in Motorola format (MSB-LSB).
The selectable input data function allows a special read access to functional module data. By setting
an address in the output word Am.1, depending on the address value in the input words Em.5 and
Em.6, 2 16-bit values or one 32-bit value can be read at the same time. In the input word Em.4, the
address of the currently shown input value is displayed. With invalid address values, the error bit is
set (Em.4, B15=1).
8.3.1 Procedure
The extended read access must be performed by the user as follows:
1. Set the desired address in the output word Am.1.
2. Compare input word Em.4 (current input address) and output word Am.1 (set address).

Input/output data
3. Distinguish between the following cases:
– Addresses are identical
èRead in valid data from input words Em.5 and Em.6.
– Addresses are different (Em.4, B15 (ERR)=0)
èInput data of the new address is not yet available. Repeat address comparison.
– Addresses are different (Em.4, B15 (ERR)=1)
èSet address is not available. Set valid address value.
As long as the set address remains unchanged, a comparison of the addresses and an evaluation of
the error bit is not necessary. The data is updated cyclically.
If an invalid or unsupported input address is set in Am.1, the set address value is taken over in Em.4
(selected input address) and bit 15 (ERR) in Em.4 is set to 1 at the same time. The selected input data
words 0 and 1 in Em.5 and Em.6 each have the value 0.
8.3.2 Output word Am.1 "Input address" [Input address]
The address of the desired input value is transmitted.

Fig. 20 Commissioning of the automatic pressure regulation and blocking function
Recommended procedure for determining the parameter "Auto-controller flow rate critical limits"
and "Auto-controller delay time"
1. Record the relevant function-specific production data.
To be able to set the parameters for the automatic blocking function of the product correctly, the
following data of the downstream system is required:
– Minimum flow rate in production operation
– Pneumatic and electrical system in operation
– Actuators in action
– Maximum time at continuous minimum flow rate (e.g. production downtime)
– Maximum flow rate for production downtime
– Pneumatic and electrical in operation
– Actuators not in action
Sample values in the “Pressurise” state:
– Minimum flow rate in production operation: 250l/min
– Maximum pause time in production operation: 2min
– Maximum flow rate for production downtime: 80l/min
79Festo — MSE6-C2M — 2019-03
Page 80
Commissioning examples of parameterisation
2. Set parameters for automatic pressure regulation and blocking function.
Additional tolerances and safety additions must be taken into account during parameterisation.
– The module must be in the operating mode "User-controlled blocking" (Am.0.1=0) for para-
meterisation and the automatic shut-off valve controller deactivated (Am.0.5=0).
This ensures that the Q_low-Timer is reset for activating the automatic blocking function and
the shut-off valve does not unintentionally switch to the blocking state.
– Set the parameter "Auto-controller delay time" (Pm.17-18). Here, set a greater value than the
actual production pause time to prevent unwanted blocking during production operation,
e.g. to 10min.
– Set the parameter "Auto-controller flow rate critical limit" (Pm.19-20). The parameter value
must be greater than the maximum flow rate for production downtime than the minimum flow
rate in production operation.
In the example, a parameter value can be set between 90 and 240l/min.
3. Activate automatic pressure regulation and blocking function.
– With the change to automatic pressure regulation and blocking function by setting the output
Am.0.1=1 and resetting the Q_low-Timer Reset function by Am.0.2=0, the parameterised
flow monitoring by the Q_low-Timer.
The Q_low-Timer status is indicated at input Em.3.4-3.5. When this time has elapsedQ_lowTimer, the automatic pressure regulation and blocking function is executed with supply air
shut-off and subsequent control to the target pressure Auto Standby if the output control
Auto-Enable is set (Am.0.5=1). This prevents unintentional blocking of the supply air and
reduction of the outlet pressure when the time has elapsedQ_low-Timer.
If the flow rate of the system exceeds the set Auto-controller flow rate critical limit for output
Am.0.5 that has not yet been set, the Q_low-Timer is reset. The Auto-controller delay time
starts again. It continues to control to the pressure setpoint Auto Normal, even if the output
control Auto-Enable is set (Am.0.5=1).
As soon as the module is in the state AUTO_SHUTTOFF (shut-off state) or AUTO_STANDBY
(control to pressure setpoint Auto Standby), this state can only be exited again by the user.
4. Switch the module from the blocking state (AUTO_SHUTOFF) or Auto Standby pressure regulation
state (AUTO_STANDBY) back to the Auto Normal pressure regulation state.
– The Q_low-Timer status is UP (Em.3.4-3.5=2) and the module status is AUTO_SHUTOFF
(Em.3.8-3.11=11) or AUTO_STANDBY (Em.3.8-3.11=12).
– To switch to the Auto Normal pressure regulation state AUTO_NORMAL (Em.3.8-3.11=8),
the Q_low-Timer Reset output must first be set (Am.0.2=1) and then reset (Am.0.2=0).
5. Check the set values over multiple production cycles.
Changes to system parameters can lead to a change in the determined production data.
• If necessary, check wither the set parameter values are still valid.
– The respective current module status can be tracked in input Em.3.8-3.11. The status of the
Q_low-Timers in input Em.3.4-3.5 and the switching position of the shut-off valve in input Em.3.0.

11.2 Commissioning example – monitoring of pressure drop
Each system must be set individually. The sample values are only intended as an orientation.
Recommended procedure for determining the parameters "Upper critical limit pressure change"
and "Pressure change sample time"
1. At output pressure setpoint P2 (Am.2), set the parameterised target pressure value Auto Normal
(Pm.21-22). Switch the shut-off valve at the control output to the pressurisation state
(Am.0.1=0). At the Auto-User control output, activate the user-controlled pressure regulation
and blocking function (Am.0.1=0).
2. Set the parameter "Pressure change sample time" (Pm.10).
If the system shows a high pressure drop, start with a setting of 100ms (corresponds to
Pm.10=1). If there is a lower pressure drop, increase the pressure change sample time, e.g. to
1s (Pm.10=10), the pressure change is displayed per 1s. Vary the parameter value until you
have determined a suitable value for your system.
3. Switch the shut-off valve to the shut-off state (Am.0.1=1).
4. Record pressure change values as long as the output pressure is greater than the parameterised
pressure setpoint Auto Standby (Pm.23-24). The values are available as selectable input data in
the inputs Em.5 or Em.6. The corresponding input address must first be set in Am.1. Z.B.
Am.0=0 indicates the pressure change in both Em.5 and Em.6.
The pressure change is a signed value. When the pressure falls, the values are correspondingly
negative.
5. Generate the amount of the pressure change. With positive values, adopt the input value, with
negative values, reverse the sign, e.g. –10 becomes 10.
6. Determine the amount of the largest pressure change value during the blocking state.
7. By repeatedly switching the shut-off valve from the pressurise to the shut-off state with the pressure setpoint unchanged, determine the largest pressure change value in the shut-off state in
terms of amount.
If you have obtained very low values, it may be wise to increase the value for the parameter “Pressure change sample time” (Pm.10).
81Festo — MSE6-C2M — 2019-03
Page 82
Commissioning examples of parameterisation
8. Set the specified value, with an added safety tolerance, for the parameter “Upper critical limit
pressure change” (Pm.15-16). In this way, you can avoid accidental error messages.
Sample values:
– Parameter “Pressure change sample time: 1s
– Parameter "Upper critical limit pressure change":
– Specified, amount of maximum pressure change value: 160mbar
– Set critical limit including safety tolerance: 200mbar
The monitoring of the pressure change only takes place in the blocking state and with activated
critical limit monitoring (Pm.0.6=1).
