This equipment is guaranteed for twelve months from the date of delivery. The terms
of this guarantee are valid provided that CONTROL TECHNOLOGY is informed of
the fact within fourteen days of equipment malfunction and the equipment is returned
to the nearest agent with a factory accredited service department. The equipment
should be suitably packed and the transport prepaid.
WARNING
THIS EQUIPMENT MUST BE HANDLED WITH THE UTMOST CARE, AS
DANGEROUS ELECTRICAL POTENTIALS ARE PRESENT WHEN A SUPPLY
VOLTAGE IS APPLIED. WHEN PRINTED CIRCUIT BOARD REPAIR OR PART
REPLACEMENT IS REQUIRED ALWAYS ISOLATE ALL SUPPLY VOLTAGES
TO THE SYSTEM.

PRODUCT OVERVIEW
The PHANTOM IV is a dual purpose controller designed to operate either as a two
quadrant DC brake or for exciting DC motor fields. With regard to the latter, it is
possible to configure the controller to operate in the field spillover mode. When used
as a straight field exciter it will accept either a voltage or current reference.
One model caters for all the single phase ranges.
Two dual thyristors in isolated packages, configured as a DC bridge ensure chassis to
mains isolation. The speed of the DC motor, armature or field, is controlled using
linear closed loop circuitry with either armature\field voltage or tachogenerator
feedback. The armature\field voltage is isolated from the control circuit by a high
impedance buffer. An ACCT derived, current feedback signal, galvanically isolated
from the control circuitry, completes the current loop.

OTHER STANDARD FEATURES
TWO QUADRANT CONTROLLER
* 220 or 380 vac supply voltage link selectable.
* Field supply selectable for 220vac or 380vac.
* On board high speed fusing of field and armature.
* Torque reference input.
* Single board simplicity, bolts directly on SCR's.
FIELD REGULATOR
* Speed linearising curve. Corrects the exponential relationship between field
excitation and motor speed.
* Current reference input, eliminates speed variations due to temperature changes in
the motor.
* Field OK relay with a normally closed potential free contact.
* Field economy. In spill-over mode the field voltage is reduced to 50% if the
armature voltage is absent for 90 seconds.
* Full block firing. Allows for trouble free control of highly inductive loads.

INSTALLATION INFORMATION
Before commissioning it is essential to ensure the following installation information
has been complied with.
1. A good air flow is essential for maximum cooling. When fitting in an enclosure
allow 100 mm clearance on all sides. If a smaller enclosure is used it may be
necessary to fit a cooling fan. When fitting in a system with cable trunking ensure
a 50 mm clearance top and bottom and 25 mm side clearance.
2. Operating temperature range 0 - 40 deg. C.
3. Avoid vibration. Excessive vibration can cause general deterioration of
connections and component damage.
4. Ensure that the motor is correctly mounted and aligned as per the manufacturer's
specifications.
5. Ensure that motor cooling accessories and
louvers are functional.
6. Check dynamic mechanical integrity of all bushes, bearings and brushgear by
manually rotating the motor.
7. Check that pulleys are correctly aligned.

8. Measure the resistance of the windings for
correct terminal allocation.
a) Low impedance across armature.
b) High impedance across shunt field.
c) Low impedance across series field.
(NOTE Shunt field should be left unconnected in a regenerative system.)
d) More than 2 mega ohm from any terminal to ground.
9. All control cabling should be 0.75 sq.mm. minimum. A noisy environment could
necessitate screening of the reference and feedback control signals. Care should be
taken in the grounding of the screen conductor so as to avoid earth loops.
CONNECT SCREEN TO EARTH ONLY AT CONTROLLER END.
10. Power cable to be minimum 600 vac rated at 1.5 X armature\field current.
11. High speed rated, are protection unit which fuses or circuit breakers, suitably
recommended for incoming supply on all versions except the 2.2 KW is internally
fused.
2.2 KW 20A
3.7 KW 25A
5.5 KW 30A
7.5 KW 40A
12. Ensure good quality earth bonding.
