Installation
400A series clocks are available with cases suitable for surface wall mounting, flush mounting in a panel with
rear access, flush mounting in a wall box and single or double sided ceiling suspension. The surface wall
mounting case is supplied with special mounting brackets to enable the angle of the front face of the clock to
Issue 2.2

Introduction - 3
be varied to reduce or eliminate unwanted reflections. Please refer to pages 24 to 28 for further mounting
information.
Power Supply Connection
400A series clocks may be supplied for 230v ac, 110/120v ac, 12v dc, 24v dc or 48v dc. The clock must be
connected to the appropriate supply after first verifying the correct voltage by reference to the supply voltage
label fixed to or printed on the rear panel of the clock.
A connection to the earth line must be made to ensure safe operation and ensure compliance
with EMC regulations.
To ensure conformance with EN60950:
(A) For installations where the 400A clock is to be permanently connected into the mains power
circuit, a readily accessible disconnect device should be incorporated in the fixed wiring.
(B) For installations where the 400A clock is to be plugged into the mains power circuit, a
socketed outlet should be installed near the equipment and should be easily accessible.
All installation work should be performed in accordance with the Sixteenth Edition of the IEE
Wiring Regulations.
An internal automatically re-charging battery will, when fully charged, maintain the internal time count for a
period normally in excess of 60 hours if the mains supply is interrupted.
The power supply is fitted with an internal 100mA fuse (450A, 490A.05 etc = 160mA fuse). In case of fault
the fuse should only be replaced by a suitably qualified engineer after disconnection from the mains
power supply and correction of the fault condition.
External Signal Connection
A six way terminal block is located on the rear panel of the clock to enable the connection of external signals.
Details of the connections for various signal configurations are shown on page 28.
The mains power supply must be disconnected when making connections to external signals.
Manual Time Synchronisation
The 400A clock or calendar clock should be set to time of day, when used in stand-alone mode, prior to the
connection of a synchronising impulse signal or in the absence of the required synchronising code or radio
signal, by means of the three time setting switches located on the rear of the clock. The locations of these
switches are illustrated on pages 24 and 28 and the setting sequence is detailed on pages 4 and 5.
401A, 420A and 490A series clocks which normally display time only may also be set to date in order to
enable automatic pre-programmed seasonal time-changes and to provide date information for serial ascii data
outputs if an optional internal serial interface module is fitted.
Optional Internal Interfaces
A range of optional internal interfaces allow connection of the clock to a variety of signals and external
equipment. The appropriate interfaces are normally factory fitted in accordance with order specification.
If it is necessary to fit a new internal interface in order to change the specification of the clock the work must
be carried out by a suitably qualified engineer in accordance with the instructions on page 20.
Guarantee
The 400A series clocks are fully guaranteed, on a return to works basis, against failure due to faulty parts or
workmanship for one year from date of purchase. In the event of failure, either within or outside the warranty
period, please pack the unit with care and return it to our factory for examination and repair.

Serial ASCII Data Formats
400A Series clocks and calendar clocks, when fitted with a 404.2 (RS232) or 404.4 (RS485) optional internal
interface module, are capable of synchronisation to one of three serial ASCII data message formats and will
transmit messages in seven formats. The clock may be programmed to receive or transmit messages at 1200,
2400, 4800 or 9600 baud - program function 10 -, seven or eight data bits - program function 11 - and odd
or even parity - program function 12.
When programmed to transmit serial messages - by selecting options 1 to 7 of program function 9 - the clock
will transmit a new message at every second edge. If the clock is programmed to transmit in one of the two
`on-demand’ modes - program function 7 , selections 4 or 5 - the message will only be transmitted following
the receipt of an ASCII `T’ or `t’ - program function 7, selection 4 - or the closure of an external voltage free
switch contact - program function 7, selection 5.

402A Stopwatch Controller - 1
The 402A Stopwatch Control unit enables a 401A,420A or 490A series clock to be used both as a
multifunction stopwatch and a time-of-day clock with the display freely switchable between time-of-day and
stopwatch time. The time-of-day count may be synchronised to a wide variety of external time codes, impulses
and time signals.
Four switches control the stopwatch count, display selection and function programming of the control unit.
The operation of these switches is illustrated on the following pages.
The stopwatch function can be programmed to count:
•
•
•
Up from zero - program function SA, selection 1.
Down from a pre-programmed start-time to stop at zero - program function SA, selection 2.
To count down and then up through zero - program function SA, selection 3. In this mode a minus
sign will appear in the left hand character position when the count is minus and the most significant
digit is zero.
•
To continuously count down to zero with automatic re-start from a pre-programmed start time -
program function SA, selection 4.
The stopwatch can be programmed to operate:
•
•
In a simple start-stop mode - program function SB, selection 1.
With one of four programmed spilt actions to enable the time intervals between sequential events to
be timed incrementally or accumulatively. Please refer to pages 14 and 17 for further information. -
program function SB, selections 2 to 5.
The stopwatch display can be programmed to show:
•
•
•
Minutes, seconds and one hundredth seconds (minutes and seconds for 420A series clocks) -
program function SC, selection 1.
Hours, minutes and seconds (hours and minutes for 420A series clocks) - program function SC,
selection 2.
Minutes, seconds and one hundredth seconds (minutes and seconds for 420A series clocks) unless
the hours count is one or more in which case the display automatically switches to show hours,
minutes and seconds (minutes and seconds for 420A series clocks) - program function SC,
selection 3.
The countdown start time can be programmed in hours, minutes and seconds (hours and minutes for 420A
clocks). The programmed time is held in non-volatile EEPROM and is automatically recalled whenever the
stopwatch is in a countdown mode and the `RESET’ switch is pressed or automatically when count option - 4
- is selected.
An optional internal interface module (404.R) provides a normally open voltage-free relay contact pair, rated
at 24v 1A dc and programmable from one to three seconds contact closure duration in steps of 0.1 seconds,
which starts when the countdown reaches zero - program function SD, selections 0 (no contact closure) to 30
(3 seconds closure).
The 402A Stopwatch Control unit can also be used to remotely set the clock to time and date.
The 402A controller unit is connected to the 401A, 420A or 490A clock by means of the three metre long
three core cable provided. The interconnecting cable may be extended to ten metres length using a screened
cable. Please refer to page 24 and 28 for details of the connections to the clock.

Internal Interface Installation
The 400A series of clocks and calendar clocks may be programmed to synchronise to and to output a wide
variety of signals. In a number of applications, as detailed throughout this manual, an optional internal
interface module must be added in order to convert the external signals into the logic levels required by the
400A series clock or to generate the appropriate output signal levels.
The required interface module will normally, if specified at time of order, be factory installed during the testing
procedure prior to dispatch. If it is necessary to subsequently install an interface module in a 400A series clock
the following steps must be taken.
•
•
Ensure that any power supply to the clock is completely disconnected.
Place the clock on a conductive, grounded, work-surface ensuring that the case body is protected to
avoid damage to the finish of the case and the front display filter.
•
•
•
•
Unscrew the cross-head self-tapping screws which hold the rear panel to the clock case body.
A ‘Pozidrive’ type screwdriver should be used and the screws saved for re-assembly.
Locate and remove the battery connection jumper - J4 - which is located above the end of the
right-hand battery. To avoid loss retain the jumper on one pin of the J4 header.
By reference to the drawing below, locate the ten pin vertical header - J5 - and remove the
standard jumper connecting pins 2 and 3.
The optional interface module must be installed with the ten way female socket mating with header
- J5. The body of the female socket must be towards the square processor chip and on the side of
the interface module away from the transformer and batteries. The side of the module carrying
surface mounted components must be towards the batteries and transformer.
•
•
Ensure that the module socket is correctly aligned with the - J5 - header pins.
Ensure that the flat, 20 way, interconnecting cable assembly between the display printed circuit
board and the power/logic printed circuit board is correctly in place with the cable mounted socket
securely seated on the shrouded board mounted plug - J6.
•
•
Replace the J4 jumper to re-connect the battery.
Carefully replace the back cover of the clock ensuring that no strain is placed on the interconnecting
cables. All of the original retaining screws must be replaced to ensure electrical and mechanical
safety and EMC screening. If any screws have been misplaced they may be replaced with No. 4 x 3/8”
self tapping countersunk screws.

Special Operating Modes
Temperature Display
Two temperature display modes are available. The temperature may be displayed continuously or alternately
exchanged with the hours and minutes time display. When the alternate time/temperature display mode is
selected the period between display changes may be adjusted by the user.
An external type 406 Temperature Sensor module is required to allow temperatures in the range -17°C to
+50°C to be displayed. The 406 module is normally supplied with a three core, 5m connecting cable which
may be user extended up to a maximum of 100m. The connection of the module to the 400A series clock is
illustrated on page 28 of this manual.
The 406 module is housed in a two part, clip together, ventilated case measuring 70mm x 70mm x 25mm
deep. The module may be mounted on a suitable vertical surface, either by the use of two strips of double
sided tape or by mechanical fixing via two screws through the marked positions in the detachable base plate
of the unit. The module must be mounted in a position where it is not subject to direct rain or other water
spray.
Please refer to pages 4 - 9 of this manual for programming information.
Important note: The clock should be programmed to the required temperature display function with the
temperature sensor disconnected. The temperature sensor must be connected to the clock after the required
display mode has been programmed.
To program a 400A series clock to display temperature information program function 7 should be set to
selection `C’ to display alternating time and temperature or selection ‘°’ to display the temperature only.
The temperature sensor is factory calibrated to +/- 1°C. However any temperature display system is subject to
errors caused by installation location related environmental conditions. The correct temperature should be
established by reference to an accurate shielded thermometer. Program function 8 allows the displayed
temperature to be corrected to compensate for errors, when program function 8 is selected the display flashes
on/off showing the adjusted temperature. The displayed value may be adjusted, up or down by up to 5
degrees, to the required corrected value by use of the `B’ setting switch. The correction factor is permanently
stored in non-volatile memory.
Program function 13 allows the `hold time’ between display changes to be set in the range 1 to 15 seconds.
Note that the alternating cycle is always returned to show time information at the start of each new minute.
Local Master Clock Mode
The local master clock mode enables any 400A series clock, when fitted with an internal 404.M interface
module, to control up to ten 400A clocks operating as slaves with a maximum cable length of 200m.
A 400A clock will only operate as a `local master’ clock if, in addition to having a 404.M module installed, it
is maintaining its timekeeping from the internal high stability crystal (stand-alone synchronisation mode) or it
is synchronised to MSF or DCF radio time code via a 484 series receiver.
Any 400A clock will operate as a `local slave’ as the interface circuit is present as standard.
The master clock should be programmed, by reference to pages 4 - 9 of this manual, as follows:
•
•
•
Program function 3 - Synchronisation mode - selection 1, 9, 10, 11 or 12 as appropriate
Program function 7 - External Controller mode - selection 0
Program function 9 - Serial Output mode - selection 0
Each slave clock should be programmed as follows:
Program 3 - Synchronisation mode - selection 17
•
The slave clocks should be connected in parallel to the master clock, by reference to the connection diagrams
shown on page 28 of this manual, using a single twisted pair cable.
The interconnecting cable may be unscreened in the majority of installations but should be screened in the
presence of high levels (1Vm) of radio frequency emissions or when the interconnecting cable runs are
adjacent to machinery or equipment likely to produce significant levels of electrical noise.
If screened cable is used the screen should be grounded at the 400A local master clock end only.
Issue 2.2
22
Radio Time Code Synchronisation
The 400A series clocks will, when connected to an appropriate 484 series radio receiver and programmed for
radio time code synchronisation, automatically synchronise to the radio time code information transmitted
from radio station DCF located at Mainflingen near Frankfurt or from MSF at Rugby. The clock may display
BST - program function 3, selection 9 - (MSF synchronised), CET - program function 3, selection 11 - (DCF
synchronised) or UTC (GMT) from either MSF - selection 10 - or DCF - selection 12. The DCF signal is
transmitted at 77.5KHz and is derived from an atomic clock at the Physics Institute of Brunswick. The MSF
signal is transmitted at 60KHz and is referenced to the Caesium Beam Oscillator at the National Physical
Laboratory.
The type 484.02 (MSF) and 484.03 (DCF) time signal receivers are housed in a compact weather-proof case
and are connected to the clock or master clock by a single cable pair. In many locations the receiver will
operate within the building. In difficult reception areas, where an external mounting point is required, the
receiver unit may be located up to 200 metres from the clock.
The type 484.06 (MSF) and 484.07 (DCF) time signal receivers are low cost units for internal use only.
Installation
The 484 series radio time code receiver should be mounted:
•
•
At least 2 metres from the 400A series clock.
At the greatest practical distance from:
Other electrical equipment including computers, fluorescent lights and signs, metal girders and
reinforced concrete walls. Any other sources of electrical noise.
•
•
Preferably on the outside of the building (484.02 and 484.03 only) as high as possible. The case is
weatherproof to IP65 but it is preferable to provide some protection from direct rain.
With the cable entry on the lower face of the case (484.02 and 484.03).
The 484 series receiver may be connected to the 400A series clock directly by means of the cable provided or,
at a greater distance, by means of a suitable extension cable.
At distances of up to 10 metres unscreened two core cable may be used. At greater distances, or in areas of
high electrical noise, a two core screened cable must be used with the screen grounded at one end only. The
maximum recommended distance between the receiver and master clock is 200 metres.
Alignment
The 484.02 and 484.03 radio receivers have dual ferrite antenna which normally permit location regardless of
orientation to the transmitter. The receiver is mounted by means of the four fixing holes in the rear surface
which are accessed after removing the front cover. The four mounting holes are located outside of the central
sealed compartment. The 484.06 and 484.07 receivers have a single antenna element and are supplied with
an adjustable mounting bracket to enable orientation with the longest face of the receiver at 90° to the
direction of the transmitter.
The front cover of the 484.02 and 484.03 receivers may be removed to enable an indicator LED to be viewed.
The indicator LED for the 484.06 and 484.07 receiver is located in the front face of the unit. The alignment of
the receiver is correct when the LED flashes on/off once per second.
Signal Reception
Under normal circumstances the DCF signal provides reliable operation at distances of up to 1500km. MSF
signals are normally usable up to 1000km. Greater operating ranges are possible at night. The received and
decoded signal provides an operating accuracy of better than +/- 20ms and provides completely automatic
seasonal time changes.
In best conditions the 400A series clock will take three minutes to synchronise with the transmitted time code
from either DCF or MSF. When the 400A series clock is `locked’ to the transmitted signal, the colon between
the hours and minutes characters is illuminated continuously. During periods of signal failure or signal
corruption the clock will maintain timekeeping using its internal high stability quartz crystal oscillator and the
colons will flash on/off every second.
It should be noted that MSF is off the air for maintenance purposes from 10:00 to 14:00 on the first Tuesday
of each month and usually for up to two weeks during the summer months for annual maintenance. The MSF
transmission status can be checked by telephoning 020 8943 6493.
