3.8 Analog interface
The analog interface allows the generator to be integrated into an SPC or
into another environment using 0…10 V or 0…20 mA interfaces.
Caution!
• To avoid damaging the generator, make sure that the signals are con-
nected correctly.
• Fusing protection for the fault alarm contact must be provided by the
customer.
• Shielded cables must be used to wire the analog interface; the shield
must make contact on both sides.
