2.0 TC6B Controller Instructions – General Instructions
SAFETY FEATURES
Numerous safety precautions are mentioned through this Instruction Manual,
failure to follow these instructions or to heed these precautions may result in
serious personal injury or property damage.
Although components within the Controller enclosure are IP2X rated “finger
safe”, the operator must be aware of the potential hazards associated with
working around live equipment and circuits.
Installation*
2.1 Installing the Controller
The Controller assembly should be installed as close to the Feeder as possible, preferably on a wall in a
clean dry location, free from excessive vibration. The standard Controller is furnished in an enclosure with
a Degree of Protection rating of IP65 that is adequate for most applications. Controllers may be supplied
to meet a variety of environmental conditions or applications requiring a higher degree of protection.
If at all possible, the Controller should be installed at a location where it will receive good ventilation. The
life of most electrical components is reduced when operating in an atmosphere of intense heat. Good
ventilation in the area of the control enclosure will permit internal heat to be dissipated through the enclosure
external surfaces and into the outside atmosphere, thus prolonging component life. The Controller
should be installed at a location where it is easily seen and accessible to the operator and maintenance
technician.
2.2 Wiring the Feeder and Controller
The power supply voltage and frequency must be as stamped on the
equipment rating nameplate.
The supply conductors and the conductors between the Feeder and Controller must be of a size sufficient
to carry the current and voltage as stamped on the equipment nameplate. The distance between the
Controller and the Feeder is an important factor that must be taken into consideration when determining
the size of the conductor. The voltage drop through conductors of insufficient size for the distances involved
will result in a definite lack of Feeder stroke and performance during operation. The further the distance,
the larger is the required size of conductor.
Connection to the Feeder must be by flexible cable furnished with the machine which should be connected
to the fixed wiring by a junction box adjacent to, but not affixed to, the drive housing. A similar cable gland
to that by which the cable enters the housing should be used at the junction box. The flexible cable should
be quite slack between these two glands.

2.3 Earthing
The Feeder drive unit is fitted with a three core flexible cable, the Green/Yellow conductor of which is
connected to the magnet core assembly and must be earthed. The Controller is provided with an earth
stud or terminal through which the Feeder earth connection is normally made.
Both the Feeder and its Controller must be properly connected to an efficient
earth, such as a water pipe, earth rod, etc, in accordance with Supply
Authority Regulations.
Operation*
2.4 Operation
Each SYNTRON Vibrator or Feeder requires a SYNTRON Controller for its operation. The Model
TC6B is the standard controller for a rectified current equipment rated up to 6 amperes at 240
Volts. This controller has a double pole single throw switch “OFF” and “ON”, which control the
starting and stopping of the vibrator or feeder.
A silicon rectifier (SCR) is used to control the voltage applied to the vibrator or feeder magnet coil.
The SCR and its control components, including a control potentiometer, are encapsulated in a
TC6B module. A potentiometer control the SCR and hence the voltage of the vibrator or feeder
magnet coil. The magnet coil, in turn controls the magnitude of vibration of the vibrator or feeder.
The controller also contains a terminal block for making electrical connections to the vibrator or
feeder and to the power supply.
The control box should be installed as close as possible to the vibrator or feeder, preferably on a
wall. It is most important that the controller is kept in a clean and dry a location as possible which
is free from excessive vibration.
Maintenance*
2.5 Setting-Up Procedure
During commissioning or for maintenance purposes, the following procedure should be carried out. This
will ensure the Controller functions correctly and the Feeder maximum stroke is as per the Specific Data
Section of this manual.
NOTE: Before proceeding to adjust the control potentiometer, check that the air gap is set as per the
Specific Data Sheet.
1. Before applying power, set the variable controls as follows: "Rate Set" potentiometer – midway.
2. Check the power supply voltage and frequency to see that it corresponds to the ratings shown on the
vibrator or feeder nameplates.
3. Check all of the connections.
4. Check the vibrator or feeder for shorted or open circuited magnet coil.

2.6 Field Checking the Silicon Controlled Rectifier (SCR)
An SCR can be difficult to check in field, because its characteristics under load are somewhat different than
when in a cold state.
A simple and effective cold state check of an SCR to determine a complete open or short is outlined below:
Isolate equipment prior to commencement of any work.
1. Disconnect the SCR from the Controller circuit.
2. Referring to Figure 10.1, construct a simple DC circuit using two flashlight batteries and a flashlight
bulb.
3. Connect the positive (+) lead to the SCR anode.
4. Connect the negative (-) lead to the SCR cathode.
IF THE BULB LIGHTS AT THIS POINT, THE SCR IS SHORTED AND SHOULD BE REPLACED.
If the bulb does not light, continue with the test.
5. Connect one end of a jumper on the anode side of the SCR.
6. Momentarily touch the gate of the SCR with the other end of the jumper lead. The bulb should now
light and stay lit.
IF THE BULB DOES NOT STAY LIT AFTER THE GATE IS MOMENTARILY TOUCHED, THE SCR IS
OPEN AND SHOULD BE REPLACED.
As mentioned before, this test is effective only if the rectifier is completely open or shorted.
Any partial breakdown of an SCR under load conditions can be determined and remedied only by
replacement of the defective SCR.
NOTE: A portable SCR tester, Part No. 047C0001, is available to perform the above functions.
