WARNING
Indicates a possible dangerous situation.
Non-compliance with this information can result in death or seri-
ous personal injuries (invalidity).
CAUTION
Indicates a possibly dangerous situation.
Non-compliance with this information can result in damage to
property or light to medium personal injuries.
NOTE
Indicates general notes, useful operator tips and operating rec-
ommendations which don’t affect safety and health of the person-

1.2 Basic safety information
This description contains the necessary information for the correct application of the
product described below. It is intended for use by technically qualified personnel.
Qualified personnel are persons who, because of their training, experience and posi-
tion as well as their knowledge of appropriate standards, regulations, health and
safety requirements and working conditions, are authorised to be responsible for the
safety of the equipment, at all times, whilst carrying out their normal duties and are
therefore aware of, and can report, possible hazards (Definition of qualified employ-
ees according to IEC 364).
DANGER
Hazardous Voltage! Failure to observe can kill, cause serious in-
jury or damage.
•Isolate from mains before installation or dismantling work, as well as for fuse
changes or post installation modifications.
•Observe the prescribed accident prevention and safety rules for the specific
application.
•Before putting into operation check if the rated voltage for the unit conforms
with the local supply voltage.
•Emergency stop devices must be provided for all applications. Operation of
the emergency stop must inhibit any further uncontrolled operation.
•Electrical connections must be covered.
•The earth connection must be checked for correct function, after installation.
1.3 Specified use
The units described herein are electrical controllers for installation in industrial plants.
They are designed for power adjustment on vibratory feed equipment.
NOTE
Any other use is inappropriate and will result in the warranty be-
coming null and void.
See also our General Terms of Business.

2Description 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 Umin / Umax 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.

NOTE
Repair work must be carried out by qualified personnel only. We
recommend that repairs are carried out on our premises.

4Operating instructions
Standard settings can be made without removing the front-panel. The setting up
components are accessed by removing the small cover on the right hand side of the
front-panel.
Figure 3: Settings
Page 12 04/03/2020 R02.1
4.1 Internal Trimmers
Trimmers Uminand Umax can be used to scale the set-point range of the controller so
that it matches the output characteristics of a particular feeder. The Umax trimmer de-
termines the 100% value of the output voltage and the Umin trimmer limits the lower
setting of the set-point potentiometer. Because the Umax trimmer setting can influence
the Umin setting, when adjustments are made the Umax trimmer should be adjusted
first, followed by the Umin trimmer. The trimmers are factory set so that Umin is approx-
imately 40V and Umax is approximately 220V (at 115V Units: Umin 20 V, Umax 105 V)
4.2 Setpoint source
Selection: Setpoint Potentiometer or Setpoint external (control current 0...20 mA)
4.3 Half- and full wave
The correct setting of the vibrating frequency is particularly important because the
wrong frequency could cause the magnet to be overloaded. This setting is made with
an internal slider switch. The mechanical frequency of the feed system must be
checked before a setting is made.
4.4 Soft start
The soft-start ramp time for the output voltage is adjusted with trimmer RT3 (0...4
sec).
4.5 Invert enable:
Change the logic function of the enable input.
5Maintenance instructions
5.1 Replacing the fuse
Procedure:
1. Always pull the plug out before opening the controller.
2. Unscrew the housing cover screws.
3. Replace the defective fuse.
4. Close the housing again.

5.2 Troubleshooting and fault repair
Table 2: Troubleshooting and fault repair
Fault:
Fault repair
Appliance not working
Check the mains voltage, check the fuses and
replace if necessary.
Is the controller input set correctly, are the
jumpers correct?
Conveyor not working
Check whether the right oscillation frequency
has been set, where necessary alter the set-
ting.
Check the mains frequency (50/60 Hz). The
oscillation frequency and the mains voltage
must conform to one another.
Umax trimmer setting too low, set Umax.
Conveyor vibrates too much, mag-
net knocking (noises)
Incorrect oscillation frequency setting. CAU-
TION! Magnet may have been destroyed by
overheating, or mechanically damaged by
knocking against something.
Umax trimmer setting too high, reset Umax if
necessary.
Magnet heats up
Incorrect mains voltage for magnet, check.
Incorrect oscillation frequency set, reset if
necessary.
