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. The product was tested with connector catalogue no. 88100729.
In order to ensure conformity with ATEX Directive 2014/34/EU, the product must be installed in such a manner
as to protect the electrical connector from mechanical stress.
WARNING:
Do not disconnect the connector while under voltage!
3.
Use 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, servo-motor control cables etc.
4.
Min. wire cross-section of supply voltage cable: 0.50 mm
2
.
For longer cabling distances use larger cross-section cables as required.
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.
