Over-temperature Protection
The UCSC controller uses internal temperature readings and logic to protect its internal electronics. Internal circuitry
generates a warning at 85°C (185 °F) and shuts down at 95°C (203 °F). The UCSC will reboot once the internal circuitry
detects the temperature has dropped below 75°C (167 °F). Independently, the microprocessor monitors its operating
temperature and generates a warning at 105°C (221 °F) and shuts down at 107°C (225 °F). A power cycle is required to
recover from a microprocessor over-temperature shut down. Both of these warnings drive the OT LED and are annunciated as
diagnostic alarms.
2.1.5.4
UCSC COM Port
Typically used by GE to troubleshoot in the field, the UCSC COM port accepts a UCSC COM port
and a standard
serial to USB cable is used to connect to another computer. Use Cat5e or better Ethernet cable for this connection. The COM
port can also be used to set the controller’s UDH network address. For these instructions, refer to the
ToolboxST User Guide
for Mark VIeS Functional Safety Systems
(GEH-6862), the section
Configure and Transfer IP Address to UCSC Controller
.

UCSC Embedded Field Agent (EFA)
The Embedded Field Agent (EFA) provides connectivity to GE Predix* cloud-hosted applications and datastores through a
local Predix machine interface that runs within a Linux virtual machine on the UCSCH1. The EFA has two primary functions:
•
Collecting and transmitting machine data securely
•
A platform for running Predix apps on the Edge directly on the machine
Once a Field Agent is up and running, data is transferred from the plant to the cloud over encrypted channels, preserving its
time stamp, quality, and fidelity. It also provides a rich domain application environment for edge processing, so logic can be
executed at the most appropriate place in the architecture — locally on the machine or in the cloud.
