8.1 Before installation
•
Read the instruction manual carefully, in certain circumstances there are additional instructions relevant
to the installation of a particular controller (special attention should be given to warnings).
•
Isolate from the mains supply, i.e. do not plug into mains socket.
•
Connect the control according to the connection diagram.
•
Adjust set-point to zero and put the unit mains switch in the off position.
•
Insert the plug into the mains supply socket.
•
Switch the unit on.
•
Enable the unit, if necessary, perhaps from a supervisory system.
•
The feeder throughput can now be adjusted using the set-point potentiometer (display).

8.1.1 Setting the mechanical vibrating frequency
It is essential to set the frequency of the coil current, correctly, otherwise there will be a loss of feeder
throughput or the coils will overheat. The vibrating frequency for
thyristor
or
triac controllers,
is selected by
using a switch (normally a link switch), depending on the type of controller. The programming menu is used
in digital controllers.

Line reactor
Recommended for reducing mains distortion
(PFC) and protecting the drive unit under harsh
operating conditions.
Reduces down time and Increases operating
life.
Transient suppression device
Recommended in industrial situations
where there are frequently-switching heavy
loads or there is a high predominance of
thunderstorms.
Fuses for short-
circuit protection
