2.2.3 Overload Indication
Coaxial socket SKT5 is energised when the power supply overload circuits operate,
and it should be connected to the central overload trunking. The centre pinis line and,the screening
is connected to common rail. .
2.2.4 Monitor Socket
The Plessey socket SKT6 carriesall the stabilised HT supplies and may be connected
to the central overload position to provide remote monitoring of the supply lines.
2.2.5 Monitor Socket
The coaxial socket SKT7 mounted on the front panel of the instrument may be connected
to each of the stabilised HT lines in turn by depressing the relevant button. This provides local
voltage measurement. The centre pin is line and the screening is common rail.
Note: The push buttons are electrically interlocked to prevent any accidental shorting of two lines
through the meter. If more than one button is pressed, the meter will read the most negative vol-
tage selected. Following the pin assignments given, connect the unit into the equipment it is to
supply. .

2.3 Supply Voltage Setting
Set both mains voltage selector panels to the local supply voltageand set the switch SA to 110V
or 220V according to the range of voltage in use. These controlsare onthe rear of the instrument.
2.4 Rail Voltage Setting
2.4.1 Switch on L.T. mains and allow valves time to warm up. Check that heaters are
glowing in all valves except V16 and V17.
2.4.2 Switch on H.T. mains, plug in a suitable meter to the monitor socket on the front
panel. Push the +300V button and adjust RV3 to give +300V reading.
2.4.3 Reverse the meter lead polarities and push the -200V button; adjust RV2 to obtain a
reading of -200V.
2.4.4 Push the -308V button and check that the meter reads 308 +4 volts.
2.4.5 Connect the meter between pin A and pin 6 onthe printed circuit board of the centre
tray. Adjust RV1 to givea reading of 0 +20V.
2.5 Final Checks
Install the unit in the rack and connect all lines, switchon L.T. supply. Allow approximately
one minute warm up time then switch on H.T. Check that 'H. T. on' lampis glowing. Use remote
monitoring facilities.to check line voltages.
2.6 Resetting
If the unit trips following an overload, clear the fault condition from the equipment, then press
the button marked L.T. then the button marked H.T. If the remote power switches have been left
on, a suitable warm up period must elapse before the H.T. button is pressed.

CIRCUIT DESCRIPTION
General *
3.1 The circuit description which follows should be read in conjunction with the circuit diagrams
at the rear of the manual. It is written in sections corresponding to the circuit functions which are
illustrated in the block diagram.
Power Input
3.2 The power input to the supply is through a six pin Plessey plug PL1, the pin assignments of
which are listed in paragraph 2.2.1. The supply lines then pass through the double pole switch SA
to the overload cutouts CB1 and CB2. SA is.set to either 110V or 220Vandselectsa suitable current
rating for the cutouts. Both sides of the supply are then connected through the mains voltage selec-
tor panel to the primaries of the two transformers.
3.3 The primary of each transformer has two identical windings which are connected in parallel
for 110V working and inseries for 220V working. Five volt stepsare provided from 100-120V and
ten volt steps from 200-250V.
L.T. Supplies
3.4 The L.T. transformer has nine secondary windings which are allocated as follows:

+300V and C/R and these windings operate ata d.c. potential of approximately +25V. One side of
3.6 The +300V Supply
The +300V line is obtained from the rectified output of secondary 1 on the H.T. transformer.
This winding delivers 310V RMS on pins 11 and 12 and is rated at 450mA. The rectifier uses 8
silicon diodes MR3 to MR6 and MR11 to 14 connected as a bridge with two diodes in series in each
arm. The rectified output is smoothed by the reservoir capacitor C5.
3.7 The series control element consists of six triode-connected pentodes V1, 3, 5, 8, 10 and 12,
in parallel. The potential across these valves is, varied by the control amplifier to obtain a stabilised
constant voltage output. A one amp fuse in the anode circuit of these valves protects the supply
against overload on this line only.
3.8 The voltage reference tube V16 is connected in series with R90 between the C/R and the -200V
supply and provides an 85V reference. This is compared with the +300V supply in the feedback net-
work consisting of R86, RV3, R87 and R88. DC Signals are taken from the wiper of RV3 to the
grid of the control amplifier V13B through R84. C19 connected directly from the +300V lineto V13B
ensures no loss of loop gain to a.c. Signals.
3.9 The control amplifier consists of V13B, V14B and V14a. Signals are amplified in the pentode
V13B and coupled into the cathode of V14B. The screenof V13B andthe gridof V14B are referred
to the same d.c. potentialatthe junctions of R76 and R74. The Signals further amplified in V14B,
are coupled to the grid of V14A, connected as a cathode follower. This provides a low impedance
drive signal for the grids of the series control valves.
3.10 The -200V Supply
The -200V line is obtained from the rectified output of secondary 2 on the HT transformer .
This winding delivers 230V RMS pins,13 and 14, andis rated at 450mA. The rectifier uses 8 silicon
diodes MR7, 8, 9 and 10, 15, 16, 17 and 18 connected as a bridge with two diodes in series in each
arm. The rectified output is smoothed by the reservoir capacitor C6.
3.11 The series control element consists of five triode connected pentodes V2, 4, 6, 9 and 11 in
parallel. The potentialacross these valves is varied by the controlamplifier to obtaina stabilised
constant voltage output. A one amp fuse in the anode circuit of these valves protects the Supply
against overload on this line only.
3.12 The feedback network consists of R89, RV2 and R85 in series between the +300V line and the
-200V line. DC Signals are takenfrom the wiper of RV2 tothe grid of V1I5B. C21 connected from
-200V to the grid of V15B ensures no loss of loop gain for AC.
the amplifier, C11/60 is a response shaping network to improve amplifier Stability. The output
from the cathode of V13A drives the series control valves.
3.14 The -308V Supply
The -308V Supply is obtainedfrom the rectified output of secondary 3 onthe HT transformer.
This winding delivers 140V onpins 15 and 16 andis rated at 20mA. The rectifier uses two silicon
diodes MR1 and 2 connected in series as a half wave rectifier. The rectified output is smoothed
in the reservoir capacitor C4a and in the Smoothing network R7/C4b.
3.15 The positive of this Supply is connected to the -200V line. The negative side feeds the neon
V17 through resistor R10. Theneonhas anormal burning voltage of 108 volts which, added to - 200V ,
gives a bias Supply at -308v,
3.16 The Overload Circuits
The comprehensive overload protection can operate in several ways to give protection if either
Supply deviates unduly or if there is a drastic overload.
3.17 In the event of a serious overload either on the HT or LT transformer, or both, the main cir-
cuit breakers CB1/CB2 will Operate. This removes power from the overloaded circuits and connects
the supply line through R45 and ILP2 to the overload circuits. The Signal is then coupled through
C8 to the central overload trunking.
follower V7B. If the ~200V line potential moves out of tolerance the voltage across the overload
neon ILP2 will reach Striking potential. The heater voltage of V7 will then be coupled through C8
to the central overload trunking.
