5 Product Overview
5.1 Structure
5.1.1 Product Design
Fig. 1 Product Design
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).
