Determining the output frequency
(vibrating frequency)
It is essential that the output frequency is adjusted
with the set point set at a low frequency, otherwise on
hitting the resonant frequency, it is possible to achieve
a high amplitude with a low output voltage. An analog,
effective value, current indicating unit (moving iron
meter) must be connected into the output circuit.
Resonant is reached when there is a maximum
amplitude for a minimum output current. To
achieve a stable feed system, there must be
an offset between the vibrating frequency and
resonance (approx. 1…2Hz). This offset must be
determined by the user because different feeders
have different running characteristics.
To turn the feeder or conveyor ON/OFF remotely with a contact:
Refer to the control schematic on page 23 of this IOM.
The wire jumper between terminal 5 and 6. should be removed.
Dry contact to be connected between terminals 5 and 6..
Manual switch on face plate of controls to be in ON position.
To turn the feeder or conveyor ON/OFF remotely with a 24V DC signal:
Refer to the control schematic on page 23 of this IOM.
The wire jumper between terminal 5 and 6. should be removed.
24.V DC signal to be connected to terminal 5 and ground to terminal 4..
Manual switch on face plate of control to be in ON position.
