Technical notes on the cable

Version: – Multi-wire cable– Extra-finely stranded wire

to VDE 0295, Class 6– Protective conductor, green/yellow– Cu braided screen

Types: – e.g. Ölflex-FD 855 CP (from Lappkabel company)

No. of wires: – Determined by type of valve, plug types and signal assignment

Cable Ø: – 0.75 mm2 to 20 m length– 1.0 mm2 to 40 m length

Outside Ø: – 9.4...11.8 mm – Pg11– 12.7...13.5 mm – Pg16

NoteVoltage supply 24 V DCnom, if voltage drops below 18 V DC, rapid shutdown resembling “Enable OFF” takes place internally.In addition, with F1 version:ID–E ≧ 3 mA – valve is activeID–E ≦ 2 mA – valve is deactivated.Electrical signals emitted via the trigger electronics (e.g. actual values) must not be used to shut down safety-relevant machine functions! (See European Standard, “Technical Safety Requirements for Fluid-Powered Systems and Components – Hydraulics”, EN 982.)
