Description of the device
2.1
General
Electronic controller IRG1-S for the infinitely variable regulation of magnetically driven
vibratory bowl, linear or hopper feeders.
The units operate using the phase-angle control principle to provide a variable output
voltage for the drive magnet. Feeder throughput is adjusted with a potentiometer fit-
ted in the front plate. The control range of the potentiometer can be scaled by using
internal trimmers U
min
/ U
max
so that adjustment is linear from 0...100 %. The control-
ler can be used with vibratory feeders that have a tuned frequency of 6000 vibs/min
(7200 vibs/min) or 3000 vibs/min (3600 vibs/min) (also referred to as full and half-
wave). The running frequency can be selected by setting an internal switch (see set-
tings). An adjustable soft-start timer is provided to ensure that the feeder starts up
smoothly when the mains supply is switched on or the control input is enabled.
The controller can be enabled with a 24 Vdc signal from a PLC, for example (control-
ler runs when signal voltage is applied).
Supply voltage variations are eliminated by an internal compensation circuit so that a
constant feeder throughput is always maintained.
NOTE
Miniature magnets can also be operated safely at the IRG 1-S con-
troller!
CAUTION
In the case of applications that require the oscillation conveyor to
be switched ON and OFF constantly (e.g. dust switching, hopper
control system, etc.), the prescribed controller input must be
used. If the load circuit is disconnected with a switch or a relay
the controller may be damaged.
If the controller is switched on, never insert or remove the plug at
the vibration conveyor being operated. This can damage the ap-
pliance.
