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 wall mounting brackets. Please refer to pages 14
and 15 for further mounting information.
Power Supply Connection
470/474A series of time zone displays are manufactured with universal mains power supplies enabling
operation at voltages from 100 to 240V ac 50/60Hz without adjustment.
Issue 2.1

Introduction - 2
A connection to the earth line must be made to ensure safe operation and compliance with EMC
regulations.
To ensure conformance with EN60950:
(A) For installations where the 470/474A 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 470/474A 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, or equivalent local standard.
When time zone displays are used as stand-alone units an internal automatically recharging battery will, when
fully charged, maintain the internal time count, for a period normally in excess of 24 hours, if the mains
supply is interrupted.
The power supply is fitted with an internal fuse. In case of fault the fuse should only be replaced with a fuse of
the same rating, 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,
radio time code receivers and slave displays. Details of the connections for various signal configurations are
detailed on page 16.
The mains power supply must be disconnected when making connections to external signals.
Clocks supplied for ceiling suspension are supplied with flying leads to allow for external connection of mains
power and synchronisation signal. Please specify external synchronisation type at time of order to ensure that
the 470/474A time zone display is supplied correctly configured.
System Programming
470A series time zone displays are normally supplied factory programmed to operate in accordance with the
customer’s order specification. The program settings may be checked or altered at any time by following the
steps detailed on pages 5 to 11 of this manual. In case of doubt please do not hesitate to contact your
supplier or our factory technical support.
408 Remote Control
A 408 Remote control unit is available for to allow remote programming of your 470/474A series time zone
display. The 408 Remote control has a range of 3 metres and replicates the buttons located on the rear of the
time zone display. When the remote control is used with 474A style time zone displays the remote should be
aimed towards the right most time zone when the buttons are pressed. With a 470A time zone display the
remote control should be pointed towards the bottom time zone.
If you would like to purchase a 408 Remote control for use with a 470/474A series time zone display, please
contact your local sales representative.
Guarantee
The 470A series time zone displays 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.

Operation with 482D, 4800 and 4850 Master Clocks
w482 Time Code Operation
Most 470/474A time zone displays are used in conjunction with a 482D, 4800 or 4850 master clock. The
Master Clock provides centralised control of one or more 470/474A series time zone displays using the
w482® time code system.
The w482® signal was developed for controlling electronic clocks, using a single cable pair data
interconnection, in electrically noisy environments. A principal advantage of w482® is the ability to provide
time information in any one of fifteen different synchronised time zones. All fifteen time zones can be
individually configured on the Master Clock to provide automatic seasonal time change correction.
The w482® signal is transmitted at 4-24v amplitude at a rate of 50 bits per second. The signal is virtually
immune to electromagnetic interference. One 482D, 4800, or 4850 unit can control up to fifty 470/474A
series time zone displays located up to 1km from the Master Clock unit using a simple, non-critical cable pair.
If your 470/474A series time zone display has been supplied with a Master Clock, it will already be
programmed so that the individual time zones are set to display the correct w482® zones. ( i.e. If the Master
Clock is setup so that Zone 1 is New York time, then the zone labelled “New York” on the 470/474A time zone
display should be set to Zone 1 or Z1.)
Refer to page 16 for w482® connection information.
If the 470/474A series time zone display is to be used with an existing system, the setup should be checked
and adjusted as follows:
•
Refer to page 5 - Function Programming, and ensure that program PC 07 is set to w482.
•
Refer to page 6 - w482 Code Synchronisation - Zone Allocation, and check the setup of the various
zones. Adjust if necessary.
•
If the time zone display is a 470A or 475A unit refer to page 11 - 470A and 475A Calendar Display
Programming, and check the calendar language setting and the linked time zone.
Once the 470/474A series time zone display is connected to the Master Clock all the time zones should
synchronise correctly following the next minute edge.

Stand-alone, MSF, DCF, GPS and Local Synchronised Operation
Stand-alone Operation
The 470/474A series of time zone displays can be used as stand-alone displays, deriving the timekeeping from
a highly accurate internal quartz crystal oscillator. Each time zone can be programmed to automatically adjust
for individual seasonal time changes according to British, European or North American conventions.
The first time zone on the left of the display (bottom time zone for 470A displays) is the master time zone.
The master time zone allows the current minutes and seconds values to be set. For the other time zones, the
offset from this zone is programmed in 30 minute increments.
The procedure for setting up a 470/474A series time zone display for stand-alone operation is as follows:
•
Refer to page 4 - Function Programming, and ensure that program PC 07 is set to SA.
•
Refer to pages 7-10 - Time and Date Setting 1-4, and set the current zone times.
•
If the time zone display is a 470A or 475A unit refer to page 11 - 470A and 475A Calendar Display
Programming, and check the calendar language setting and the linked time zone.
MSF, DCF and GPS Operation
Time zone displays can be used with both the 484 series of MSF and DCF radio receivers and the 488 GPS
receiver to provide accurate time synchronisation. Refer to pages 12 - 13 for more information on installing
and using MSF, DCF and GPS receivers.
•
Refer to page 4 - Function Programming, and ensure that program PC 07 is set correctly:
~
PC 07 set to MSF if the 470/474A time zone display is being used with a 484.02 or 484.06 radio
receiver.
~
PC 07 set to DCF if the 470/474A time zone display is being used with a 484.03 or 484.07 radio
receiver.
~
PC 07 set to GPS if the 470/474A time zone display is being used with a 488 GPS receiver
system.
•
Refer to pages 7-10 - Time and Date Setting 1-4, and set the current zone times. The setting “SM”
(Synchronisation Mode - page 9) determines whether only the current zone minutes and seconds are
synchronised to the input time signal (setting “M”), or if the zone time is completely synchronised to
the input signal (setting “C”).
•
If the time zone display is a 470A or 475A unit refer to page 11 - 470A and 475A Calendar Display
Programming, and check the calendar language setting and the linked time zone.
Local Master Operation
A 470/474A series time zone display can be used to synchronise 10 other 470/474A displays at a distance of
up to 100m using a simple cable pair. When synchronised to a Local Master, only the minutes and seconds of
each time zone are synchronised.
•
Refer to page 5 - Function Programming, and ensure that program PC 07 is set to LOC.
•
Refer to pages 7-10 - Time and Date Setting 1-4, and set the current zone times.
•
If the time zone display is a 470A or 475A unit refer to page 11 - 470A and 475A Calendar Display
Programming, and check the calendar language setting and the linked time zone.
•
Refer to page 16 - External Signal connection, for details of how to connect 470A series clocks using
the Local Master function.

MSF, DCF and GPS Time Code Synchronisation - 1
470A series time zone display units will, when connected to the appropriate 484 series radio receiver and
programmed for radio time code synchronisation, automatically synchronise to time and date information
transmitted from radio station DCF located at Mainflingen near Frankfurt or from MSF at Rugby.
Only the local or other appropriate zone - refer to ‘SM’ programming function on page 9 - will be totally
synchronised to the radio signal with automatic seasonal time change correction. The minutes and seconds
count of the remaining time zones will be maintained in synchronisation with the radio signals, the hours and
date count incrementing normally unless altered manually or by an individually pre-programmed seasonal
change.
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 3 metres from the 470/474A 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 470/474A 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 time zone display is 200 metres.
Alignment
The 484.02 and 484.03 radio receivers have dual ferrite antenna which will normally permit installation
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
90º 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, with greater operating ranges possible at night. The received and
decoded signal provides an operating accuracy of better than +/- 20ms seconds and provides completely
automatic seasonal time changes.
In ideal conditions the 470A series time zone display will take three minutes to synchronise with the
transmitted time code from either DCF or MSF. When the 470/474A series clock is ‘locked’ to the transmitted
signal the colon between the hours and minutes characters is illuminated continuously. During periods of DCF
12
Issue 2.1
MSF, DCF and GPS Time Code Synchronisation - 2
and MSF Radio Time Code Synchronisation signal failure or signal corruption the clock will maintain
timekeeping using its internal high stability quartz crystal oscillator and the colons on the ‘local’ display 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.

GPS Satellite Time Code Synchronisation
470A series time zone displays can be synchronised to the time signals from the 21 satellites forming the GPS
navigation network.
The GPS satellites transmit highly accurate, real time, worldwide navigation information at a frequency of
1575.42MHz.
The 488GPS receiver system comprises an active antenna and receiver/decoder units which provides a UTC
based w482 time code output which can be used to synchronise a master clock system or up to ten individual
470A series time zone displays.
470A series time zone displays synchronised by GPS signals are accurate to within 5mS at any point on the
surface of the earth.
The 488GPS system is designed for simple installation and operation. Please request a 488GPS system data
sheet for further information.
