5.2 Function
The product smoothes out pressure fluctuations in pneumatic systems. The elec-
tric drive unit enables the output pressure to be adjusted in the pneumatic
closed-loop controller. The product is controlled via digital input signals. This
determines the direction of rotation of the drive unit and enables the output pres-
sure to be adjusted in an increasing (UP) or decreasing (DOWN) direction. The
pressure control works mechanically.
6 Assembly
1. Observe the flow direction from 1 to 2 è 5.1.1 Product Design.
2. Mount the product using the mounting accessories provided. The opening of
the exhaust valve 2 must not be blocked.

7.2 Electrical Installation
WARNING!
Risk of injury due to electric shock.
• For the electrical power supply, use only PELV circuits in accordance with IEC
60204-1/EN 60204-1 (Protective Extra-Low Voltage, PELV).
• Observe the general requirements of IEC 60204-1/EN60204-1 for PELV cir-
cuits.
• Only use voltage sources that ensure a reliable electric separation from the
mains network in accordance with IEC 60204-1/EN 60204-1.
Protection against electric shock (protection against direct and indirect contact) is
guaranteed in accordance with IEC/DIN EN 602041 by using PELV circuits (elec-
trical equipment of machines, general requirements).

8 Commissioning
The output pressure can be set via the digital inputs on plug M12 or via the oper-
ator unit (MSE6-LRE-...-OP) è 9 Operation.
With simultaneous control, the operator unit has higher priority than the signal
lines at plug M12.
1. Switch on the operating voltage.
2. Close product. Control the drive unit in the direction DOWN.
3. Pressurise the system slowly.
4. Control the product in the direction UP up to the desired output pressure. The
pressure regulation range must not be exceeded
è 13.2 Technical Data, Pneumatic.
Correctly pressurised, the input pressure is 0.5bar higher than the output
pressure.
9 Operation
A new output pressure must always be set in a pressure rising direction. During
control, observe the ratio between the control duration and pause.
The desired output pressure is lower than the current output pressure:
1. Control the product in the direction DOWN until a value of at least 0.3bar
lower than the desired output pressure is reached.
During the control in the direction DOWN, take into account that the product
has a lower exhausting capacity
– The product adjusts faster than the output pressure is reduced.
This may result in the output pressure not corresponding to the desired
control pressure when electrically querying and evaluating the output
pressure. This must be taken into account when exhausting larger initial
volumes.
2. Control the product in the direction UP up to the desired output pressure.
In the event of a power failure, the last setting of the output pressure remains
stored èFail-safe mode.
The pneumatic pressure control is guaranteed.

RUN Mode
The default state of the product is called RUN mode. It indicates the current out-
put pressure.
Change from EDIT mode to RUN mode:
– Press EDIT button for 3s or
– Expiration of monitoring time/timeout of 75 s
EDIT Mode
Adjust output pressure and pressure unit:
1. Press the EDIT button 3.
Only when the safety lock is activated:
– The display element [lock] 9flashes
– Press the [DOWN] 2 pushbutton or the [UP] 4 pushbutton until the
selected security code is set.
– To confirm, press the Edit button 3. If the correct entry is made, the
safety lock is released. If an incorrect entry is made, the safety lock
remains in effect. The unit returns to RUN mode. The procedure must be
repeated.
2. The adjustment bars 5 flash. Press the [DOWN] pushbutton or the [UP] push-
button until the desired output pressure is set. Exceeding the pressure regu-
lation range is possible and is indicated by a flashing value in the display.
3. Confirm with Edit button
4. The display elements [kPa], [psi] or [bar] 7 flash. Set the desired pressure
unit with the [DOWN] and [UP] pushbuttons.
5. Confirm with Edit button
6. The display element [lock] flashes. Use the [DOWN] pushbutton or the [UP]
pushbutton to set the desired security code (0…1999). The value 0 deactiv-
ates the safety lock.
7. Confirm with Edit button. The product is back in RUN mode.
