TTM 01-G Manual / October 2018 4
Introduction
Welcome to the TTM 01-G user manual! This document contains everything you need to know about the key
features, hardware, and installation process of the TTM 01-G.
Product Overview
The TTM 01-G is a powerful and cost-effective synchronization solution for Remote Terminal Units (RTUs),
Protection Relays and other Intelligent Electronic Devices used in electrical sub-stations and industrial control
installations.
Utilizing state of the art technology, this compact unit locks onto atomic clock references from the GPS and
GLONASS satellite constellations and produces time codes and pulses with sub-microsecond accuracy and
precision.
The TTM 01-G clips onto a standard DIN rail. Its rugged compact design is suitable for noisy electrical
environments, while built in electrical isolation combined with strong push pull drives on outputs simplifying
wiring schemes and enhancing reliability. Refer to Figure 1.
Figure 1 - TTM 01-G Front View
Accessories
The TTM 01-G comes complete with Ethernet cables to allow for customization and easy setup from the
Windows™ Configuration software which is available to download from www.support.tekon.com
Optional accessories include antenna, low loss antenna cable, antenna pipe mounting components, lightning
protection kit and BNC to 2-pin connector adaptor.

LED Indicators
The top of the TTM 01-G features two LED indicators. The SYN LED shows synchronization status, while the ALM
LED shows the alarm status of the unit.
Outputs are synchronized to UTC time only when the SYN LED is fully illuminated.
Table 1, Table 2 and Table 3 below provide information regarding the interpretation of the LEDs.
SYN LED
Meaning
Off
The TTM 01-G has no power.
Slow Flash
(1x flash per
second)
The TTM 01-G is operating in the “holdover” state (holdover timer is running) or is
operating in the “tuning” state (time server is gaining synchronization).
Fast Flash
(5x flashes per
second)
The TTM 01-G is not synchronized (out of sync and not in holdover).
On
The TTM 01-G is synchronized.
Table 1 - SYN LED Functionality
ALM LED
Meaning
Off
The TTM 01-G is operating normally and has no alarms.
Fast Flash
(5x flashes per
second)
At least one alarm is active. Refer to the alarm window in the Clock tab of the Configuration
Tool to find the name of the active alarm(s). Refer to Table 3 below for the details on each
alarm by name.
Table 2 - ALM LED Functionality
Alarm Name
Specification
Satellites Low
The number of satellites currently being used for time and position calculations is below the
threshold.
No Sync
The TTM 01-G is not synchronised to any source, or holdover period has expired, or the
timing output inaccuracy has been exceeded.
Holdover
The TTM 01-G has lost synchronization to any source and is now in holdover.
No Antenna
The antenna circuit current drain is low (typically under 3mA). This could be caused by poor
connections, or if the connected antenna has a lower current drain specification or if a
component in the antenna system is providing power to the antenna and therefore the TTM
01-G is not seeing a connected load, or if there is no antenna connected.
Antenna
Short
The antenna circuit current drain is high (typically over 100 mA). This is caused by a short in
the antenna circuit, or by moisture ingress in the circuit, or if the antenna connected has a
higher current drain specification.
Antenna
Fault
This alarm is generated if there is high current or low current detected on the antenna input.
Factory Reset
Armed
This alarm is generated if the Forgotten Password Reset (Factory Reset Process) is enabled
and has been initiated by the user.
