Overview

Each Tricon chassis includes two power modules, with either one capable of operating the Tricon at full load and rated temperature independently. These modules are hot-swappable, allowing for online replacement. Positioned on the left side of the chassis, the power modules convert line power to DC power suitable for all Tricon modules.

System grounding, incoming power, and hardwired alarm terminal strips are located at the lower left corner of the backplane. The incoming power should be rated for at least 240 watts per power supply.

Power module alarm contacts are activated under the following conditions:

• A module is missing from the system.
• The hardware configuration conflicts with the control program’s logical configuration.
• A module fails.
• A main processor detects a system fault.
• Primary power to a power module fails.
• A power module has a "Low Battery" or "Over Temperature" warning.
