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.
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.

This alarm comes up when the DHCP server is unavailable or when the IP address is assigned Address Fault to some other node in the network and cannot be assigned to the TTM 01-G Ethernet port. Under such situations the Ethernet port defaults to a link local address.
SMA male connector center pin is straight before plugging in. Antenna Cable Considerations The TTM 01-G antenna port expects a signal with a gain of at least 15 dB, and no more than 35 dB, with 20 – 35 dB being the optimal gain range.
ETH: Ethernet Interface (ST Fiber / RJ-45) TTM 01-G units are fitted with either an RJ-45 10/100 Mbps Ethernet interface or an ST multi-mode Fiber 100BASE-FX Ethernet interface. The unit can be configured over the LAN (Local Area Network) and can be loaded with PTP or NTP / SNTP Licenses.
The TTM 01-G operates with the alarm relays energized during normal operation, and de-energized in the alarm state. It follows that, in the event of all power to the TTM 01-G being lost, the alarm relay defaults to the “alarm”...
Software Configuration Tool The TTM 01-G can be configured via Ethernet. The configuration tool can be downloaded from the Tekron Support website: www.support.tekon.com. By default, the unit is shipped with DHCP enabled for automatic IP address assignment, with a fall back to link local addressing (169.254.xxx.xxx) if no DHCP server is present.
Installation Identification Each TTM 01-G unit is shipped with an identification label on the side of the case. The label provides details of the optional output (if any), the power supply fitted to the unit, and the unit’s serial number.
Figure 5). This must be connected to earth for full protection of the TTM 01-G. Figure 5 - GND screw clamp The unit must be safety earthed whenever it is powered on, using the earth terminal as pictured in Figure 5 .
Mounting the TTM 01-G The TTM 01-G is designed to be mounted to a standard 'Top Hat' din rail mount using the supplied clips on the base (see Figure 6). The clips can also be used to screw mount the unit by extending them beyond the case edge.

Factory Reset The TTM 01-G features the ability to reset to factory default settings in the event that the administrator password is forgotten, or if the time server is rendered unreachable on the network due to incorrect settings, provided that physical access to the unit is available.
Optional Output Cards The TTM 01-G has a slot for one I/O card, to allow a variety of user interfaces. Each card is limited to one additional port with at least 3 kV isolation from the rest of the system to avoid current loops.
The power supply isolation varies from 1.6 kV for low and medium voltage power supplies to 3 kV for the high voltage power supply. In addition, isolation protects the internal electronics from longitudinal transient voltages and transient suppression devices protect from transverse transient voltages.

A lightning protection kit should be fitted into the antenna lead-in cable if lightning strikes are a risk in the location of installation. The Tekron supplied antenna kit can be ordered with a lightning arrestor, two coaxial cable connectors, a connector crimp tool, and mounting hardware.
