Installation and Operating Instructions
1.
Before putting into operation carefully check all electrical connections and the supply voltage (24 VDC ±10 %).
Overload can destroy the electronics. Recommended pre-fuse T2.0 A.
2.
The electrical connection is made with a round connector M12x1. The connector must meet the requirements of
DIN 60079-15.
WARNING:
Do not disconnect the plug while under voltage!
When disconnected from power, use supplied protection cover to ensure IP protection.
3.
Use unshielded or shielded cables for the electrical connection of the valve. The shield, connector and control
cabinet must be EMC compliant. The valve body must be electrically connected to ground (PE, machine ground).
Do not run control cables parallel to high-voltage lines or servo-motor control cables.
4.
The cable length between the IO-Link master and the valve must not exceed 20m.
5.
Make sure that the valve is under pressure when a setpoint signal is applied to the valve (applying a setpoint
signal with no pressure on the valve will cause it to overheat).
6.
The valve is factory adjusted.
7.
The product must be returned to the factory for repair.
Warning
These products are intended for use in industrial compressed air systems only. Do not use these products where
pressures and temperatures can exceed those listed under SPECIFICATIONS.
Before using these products with fluids other than those specified, for non-industrial applications, life-support systems,
or other applications not within published specifications, consult ASCO Numatics.
Through misuse, age, or malfunction, components used in fluid power systems can fail in various modes.
The system designer is warned to consider the failure modes of all component parts used in fluid power
systems and to provide adequate safeguards to prevent personal injury or damage to equipment in the
event of such failure.
System designers must provide a warning to end users in the operating manual if protection against a failure mode
cannot be adequately ensured.
System designers and end users are cautioned to review specific warnings found in instruction sheets packed and
shipped with these products.
