INSTALLATION
MANUAL
1. Before putting the pressure regulator into operation, carry out a careful inspection of the electrical connections and
the supply voltage (24 VDC ±10%). An overvoltage can damage the electronic systems.
Recommended fuse protection T 0.5 A
2. The electrical connection is made using a circular plug connector M12x1. The connector used must comply with
the requirements of German standard DIN 60079-15.
Safety notice:
The plug must not be pulled out when a voltage is running through it!
When the connector plug is removed from its socket, in order to maintain the IP protection class, the protective
cap supplied with the device must be fitted.
3. For the electrical connection of the valve, shielded or unshielded cables may be used. The connection, plug
and switch cabinet must comply with EMC requirements. The valve body must be electrically grounded
(protective earthing, machine grounding). Do not install control cables parallel to power cables or control cables of
servomotors etc.
4. The cable cross-section area of the supply voltage cable should be at least 0.25 mm
2
.
If long supply cables are used, it may be appropriate for them to have an even larger cable cross-section area.
5. Make sure that the valve is subjected to pressure as soon as a target value signal is sent to the valve (if a target
value setting is sent to the valve without the valve being under pressure, this will result in unacceptable excessive
heating of the valve).
6. The device is calibrated with factory settings.
7. The device must be sent to the factory if repairs are needed.
Safety Instructions
These products must only be used in industrial compressed air systems. These products are to be used in locations
where the pressures and temperatures listed under “Specifications” are not exceeded. Please take note of the
relevant page in the instruction manual.
Before using these products with fluids other than those specified in the manual, or in non-industrial applications,
life-support systems, or in other systems which are not specified in the published instruction manuals, please contact
ASCO Numatics directly.
The components used in fluid power systems can fail in various ways due to misuse, wear or system malfunctions.
System designers are warned to make it a priority to take into account the possible types of faults of all
component parts used in fluid power systems, and to provide adequate safeguards to prevent injuries to
staff or damage to equipment in the event of such faults.
System designers must provide safety instructions for the end users in the operating manual if protection against
faults cannot be sufficiently guaranteed.
System designers and end users are strongly advised to comply with the safety instructions provided
with these products.
