FACTORY INSTALLED STANDARD EQUIPMENT (Continued)
Feature
Switchgear The monitoring system includes a mimic one line that shows the generator with it's
Monitoring respective circuit breaker in a one-line representation of the system. The graphic
COLOR LED indicators display the following information:
- Generator circuit breaker open/closed/tripped
- Engine running
- System summary alarm
The monitoring system also includes an additional display conveniently monted in the
EMCP 3.3 panel. This display is a 4 line text display with pushbuttons for various
controls. This display provides quick module set up with all parameters
stored in non-volitile memory. In addition to individual module information,
each module also provides overall plant information including:
overall power production; and alarm / shutdown status of each MODULE.
The control system monitors and manages various module functions. This includes
the automatic lube oil make up system, alarms and emergency stop functions.
The 693 frame generator is provided with winding temperature sensors as standard.
The control system monitors and displays these values, providing alarm and
shutdown. Various diagnostic features are provided including breaker synchrnonizing
time out and reclose alarms, circuit breaker posistion feedback,
phase rotation mismatch, network communication error alarms,
sensor diagnostics, and multiple unit configuration checks.
