Operation Instructions
•
The metal separator should be permanently on. This will provide maximum
lifetime of the electronic circuits.
4.4
Failure Protection of the Metal Separator
The metal separators mains inlet is protected against disturbing influences.
Increased operation safety and additional protection against failures is reached
applying the following measures:
•
Use of mains filters if the mains voltage is affected by connection of large
consumers (compensation systems, welding equipment, HF furnaces, solenoid
valves etc).
•
Protection of inductive loads (solenoid valves, contactors, electromagnets) by RC
members. On switching-off of inductive loads, high voltage peaks may occur.
These voltage peaks are shortened by RC members.
