1INTRODUCTION

TCG 01 Time Code Generators produce precision time code signals, serial strings and

pulses for use in synchronising industrial control and SCADA equipment. They are ideally

suited to providing time synchronisation simultaneously to many different devices, such

as Remote telemetry Units (RTUs), Protection Relays and other Intelligent Electronic

Devices (IEDs) used in electrical sub-stations and industrial control installations.

The TCG 01 features one AM Modulated IRIG-B output, three programmable outputs

and a serial port which is user-configurable to output serial strings and report events for

units fitted with event recording capability. Factory options include an embedded

Network Time Server, and a choice of output connectors: BNC, 2-pin plug, or ST Fibre.

Non-fibre outputs that can be ordered are TTL, RS422, or high voltage switching.

All TCG 01 units feature a front panel display, giving visual feedback about the time data

being generated on the outputs. LED indicators provide “at a glance” status information.

Figure 1 – TCG-01 Front Panel

The optimised receiver/antenna system used by TCG 01 obtains time with similar to

atomic clock precision from the GPS satellite constellation. The result is output timing

accuracy similar to that normally seen only in laboratory instruments.

However, unlike laboratory instruments, TCG 01 is suited for hostile electromagnetic

environments such as sub-stations and electrical switchyards. Each output of the TCG 01

is isolated from every other output, so that attached wiring can feed out to operating

areas in different earth potential zones without compromising the overall site earthing

security. Further isolation protects the internal electronics, and transient suppression

devices protect i/o from both longitudinal and transverse high voltage events.

TCG-01 occupies less than half the width of a 1U rack space. It is supplied complete with

all hardware and software required for installation, including rack-mount kit, connectors,

30m lead-in antenna cable, and antenna.

2INSTALLATION

2.1 Packing list

Each TCG 01 kit is shipped with the following:

xTCG 01 Time code generator

xUser Manual – this document

xGPS Antenna optimised for stationary applications, with pedestal for pipe mount

xAntenna lead-in cable fitted with matching connectors

x19” Rack mounting Plate & fasteners

xMatching plug-in connectors

xRS232 Interface cable

xConfiguration Software

2.2 Mounting

The clock is designed to be mounted in a 19” rack, but may be used on a bench. The

unit is attached to the rack mount plate via the four screws shipped installed in the four

corners of the front panel.

GPS Antenna:

Detailed antenna mounting instructions are contained in Appendix A on

page 25. The antenna should be located in a position with as clear a view of the sky as

possible, over as wide an angle as possible.

The antenna should also be mounted in a

“lightning-protected zone” as far as is possible.

In practice, this means ensuring that

there is at least one other earth-bonded structure located in the same rooftop area (e.g.

another antenna, or a lightning rod) that reaches significantly higher than the top of the

GPS antenna. The GPS Antenna should be mounted so that it lies within a 45-degree

angle “skirt” from the top of the other earth-bonded structure. The GPS antenna mount

itself should also be securely bonded directly to the building protection earth – and

not

connected via any of the other earthed structures.

A lightning protection kit is available for installation in the antenna lead-in cable for

additional protection of the equipment. (See section 7.3 on page 16 for details.)

All TCG 01 antenna installations should follow the guidelines above.

3OPERATION

Connect the antenna lead and the antenna (with a good view of the sky). Then connect

the power source to P

Check the label on the base for voltage requirements before switching on!

The time required that will achieve tracking and synchronisation given a good “view” of

the sky is typically within a minute. Although reactivating a unit that was previously

synchronised 1000’s of km away from the present position will take longer but not more

than 45 minutes.

4FRONT PANEL

Figure 2 – TCG 01 Front Panel

TCG01featurestwoLEDindicatorsonthefront panel, together with a 2-line by 16-

character LCD display. The display is optimised for viewing straight on, or from below, as

the clock is a lightweight device, normally mounted at eye level or higher in an

equipment bay.

LCD DISPLAY:

The display unit updates every second, displaying day, date, time, and time

offset from UTC. It also provides more information on the GPS receiver

operation. A recessed push-button located on the front panel between the

two indicator LED’s is used to switch between display pages.

SYN LED:

This LED operates in parallel with the Sync Relay, and is active at all times

when the unit is operating with time code outputs accurately tracking the

GPS time signals.

GPS LED:

Flashing cadences indicate the status of the GPS receiver.

4.1 LCD Display

The LCD display shows a copyright message, along with the serial number and revision

level of the unit for approximately 10 seconds following power-up, (Figure 3[a]). The

display then automatically changes to the operating default, (Figure 3[b]). The user may

cycle between all four of the screens by pushing the recessed pushbutton on the front

panel between the LED indicators. The display examples below all show the same instant

in time.

[a] Start Up (Clock ID) [b] Operating Default

[c] Local Time [d] UTC Time

Figure 3 – LCD display screens

The top line of screen [b] shows the UTC offset in hours and minutes and the local date.

The local day-of-year and time-of-day are on the bottom line.

The rightmost bottom three characters provide satellite tracking information. “UTC”

denotes UTC time (similar to GMT) while “LST” denotes Local Standard Time. If daylight

savings time is active, “LST” in screen [c] changes to “LDT”, denoting Local Daylight Time.

Screen [b] shows that the clock is operating with a local time offset of 12 hours ahead of

UTC. The local date is 17th March 2003, and the local time is 11:16:53 in the morning.

Screen [c] shows the same time and date, but also indicates that the time displayed is

Local Standard Time, and that the day is Monday.

Screen [d] shows the UTC time and date, which is 11:16:53 on the evening of Sunday 16

March 2003.
