LTMTCUF Firmware Upgrade Using TeSys Programmer Tool

Overview

The firmware of the LTMTCUF control operator unit can be updated by using the TeSys Programmer Tool version 3.2.000 and above.

This chapter describes how to upgrade or downgrade the TeSys Tera LTMTCUF firmware. It explains how to prepare the LTMTCUF control operator unit and the PC, how to connect them, and how to start the TeSys Programmer Tool.

The latest LTMTCUF firmware version is LTMTCUF_HW2_V002.000.000_TERA.bin.

Setup

The following procedure describes how to establish physical link between the PC and the LTMTCUF control operator unit, and from the LTMTCUF control operator unit to the LTMT main unit:

1. Power on LTMT main unit from a separate, externally supplied control power source that is switched from outside the enclosure.

2. Connect the USB/RJ45 cable from a USB port of the PC, to the RJ45 connector port on the front face of the LTMTCUF control operator unit.

3. Connect the free end of the LTMT9CU10S cable to the HMI port on the left side of the LTMT main unit.

   NOTE: It is recommended to make a direct link between the LTMT main unit and LTMTCUF control operator unit with the LTMT9CU10S cable.

4. Route the cables to the outside of the enclosure to perform the update without exposure to energized equipment (doors closed and interlocked).

5. Use a separate externally supplied control power source that is switched from outside of the enclosure, for the power connection. The control voltage supply must match the LTMT main unit input voltage.

   NOTE: Before proceeding, make sure that the power is OFF.
