4 PREFACE
The information contained in this manual refers exclusively to JT
control systems.
It is essential that you read this manual before installation and
commissioning.
The limits specified in the technical data must be observed when using
the control system.
The guarantee for manufacturers' drives and equipment does not
cover defects caused by misuse or incorrect use of these control
systems.
The manual is divided into individual sections in accordance with the
table of contents.
Section 1 "Electrical safety" and Section 2 " Notes on EMC legislation"
must be read before working with the JT control system.
It is essential that the user familiarises himself with this manual before
using the drive/equipment or before carrying out adjustment work
specific to the operations.
Please contact the manufacturer directly if you have any questions
about the JT control system.
The manufacturer reserves the right to make product changes without
prior notice.

5 PURPOSE
The JT Control Systems are intended for the operation of vibrating
systems with manufacturers` electromagnetic drives from an a.c.
mains.
With the JT Control System the stroke (vibration amplitude) of such
an installation can be adjusted from almost 0 to maximum.
In the control mode 'K' (= voltage regulation), fluctuations in the
supply voltage of ±10% have nearly no effect on the stroke.
In the control mode 'Y' (= stroke regulation), fluctuations of ±10%, as
well as a change in the mass conditions, e.g. through bunker
pressure, have no effect on the stroke.
6 OPERATING PRINCIPLE
With the potentiometer supplied or an external mA- or voltage signal
as the setpoint source, the stroke and therefore the feed rate of an
electromagnetic vibratory system can be continuously adjusted
within certain limits (minimum or maximum value resp.).
The setpoint signal is compared with the actual value signal. (The
actual value signal is, with the control mode 'K', the output voltage of
the control system to the drive and, with the control mode 'Y', the
signal of the stroke sensor on the vibratory system). The differential
signal (regulation deviation) is passed to a PI-action controller, which
generates the setting signal for the phase control system. The
setting signal determines the firing point of the thyristor-module.
The firing pulses are passed to the thyristor-module for galvanic
separation via a firing transformer. Firing takes place only within the
positive sinusoidal half-wave. The negative is suppressed by the
thyristor. The phase control within the positive sinusoidal half-wave
controls the electrical output of voltage and current, which is passed
to the vibratory system.

The JT control system is
cooled by natural
convection. In order to
guarantee an adequate
air flow, the equipment
must be mounted upright
and the minimum
distances shown in the
adjacent illustration
observed. The cooling
air must be as clean as
possible and free of
aggressive substances.
Should the cooling air
contain dust, the cooled
areas must be cleaned regularly.

Mounting:
Fixing dimensions, also for the mains filter, are to be found in the
appendix.
The JT Control system is fixed on the assembly board with four
screws inserted through slots.
Fit four fixing screws, hook on the control unit and tighten the four
screws.
The control system should be placed in a shock- and vibration-free
position.
7.3 WIRING
Mains and drive cable sizes:
Values are based on a cable length of 50 m between the control
system and drive. The cable diameters must be increased
appropriately for longer distances.

The local regulations governing earthing and cables must be
observed.

To be used within the scope of the EC directive 89/336/EEC
concerning EMC.
As the connecting cable between electromagnetic drive and
stationary terminal box we recommend the use of a flexible cable of
the type H07RN-F resp. NSSHöU-J. For the use of screened cables
we recommend the type ÖLFLEX 540 CP.
Additional measures within the scope of the EMC
directive 89/336/EEC:
(also refer to connection diagram in the appendix)
Mains supply: For this case, the delivered mains filter must be
switched into the mains supply line of the JT
control system. The filter must be directly mounted
on the left hand side next to the JT control system.
Sufficient ground contact must be observed. The
connection between the filter (wiring side named
„LOAD“) and the JT control system must be as
short as possible. For the filter types upto 2x35 the
filter-own output wires must be used. As from the
filter type 2x50 the connection must be made by
single wires of max. 20 cm length.

For the mains supply all filters are fitted with
clamps on the „LINE“ side. The connection of the
ground conductor is built as threaded bolt as from
filter type 2x50.
Drive connection:A screened cable between JT control system
and drive must be used. The screen connection
must be as short as possible and connected to
ground on both ends.
Control cable:
The control cable must be screened
multicore flexible cable with a conductor cross-section of 0.5 or 0.75
mm² for the control system connection.
N:B.: Earth the cable screen - as short as possible - at the JT control
system end. Use the assembling bolt (see 7.1 „Construction“,
Pos.10).
The control cables must be positioned at least 0.5 m from the drive
cable, to prevent interference.
7.4 CONNECTIONS
Please refer to the connection diagram in the appendix or the
connection sheet enclosed with the control system for the assignment
of terminals for the mains, drive and control system cables.
N.B.: If the setpoint potentiometer is used, please ensure that the
correct connection sequence is observed.
7.5 SPECIAL CHARACTERISTICS
7.5.1 Regulator release
The control system is fitted with an input for the regulator release
(control system terminals X2.14/15).
The regulator is blocked when the terminals are open. The drive will
be idle.
The regulator is released when the terminals are shorted. The drive
will vibrate.
. We recommend a screened,
When the drive is switched off by the regulator release,
connection terminals X1.3/4 will not be disconnected
from the mains.
If the operating process requires the drive to be switched on and off
frequently, the "regulator release" must be used instead of switching at
the mains. The control system therefore remains connected to the
mains current.
7.5.2 Output-side switching
It is only permissible to switch the output if the control system is
switched off (at the mains end or via the regulator release). Switches
or contactors with appropriate maximum loads must be used for this.
